Description
本申请属于智能公共交通技术领域,特别涉及一种交通管理与控制服务指数的评价方法。This application belongs to the field of intelligent public transportation technology, and in particular relates to an evaluation method of a traffic management and control service index.
当前,中国已进入新型城镇化建设与快速发展时期,党的“十九大”明确提出“交通强国建设”、“交通运输引领支撑社会经济发展”战略,提出构建现代综合交通运输体系的目标,将推广智能化技术在交通运输行业的应用作为一项重点工作内容。伴随着快速城市化发展进程,实施新型城镇化建设,从供给侧进行结构性改革,需求侧管理,着力降成本、补短板、高品质、强服务,更好地服务保障社会经济平稳健康发展。城市在转型,城市交通也在转型,交通***正处在由过去历史的、静态的小数据分析模式向实时的、动态的大数据研判模式的转变。At present, China has entered a period of new-type urbanization and rapid development. The party's "19th National Congress" clearly put forward the strategies of "building a powerful transportation country" and "leading transportation to support social and economic development", and proposed the goal of building a modern comprehensive transportation system. The promotion of the application of intelligent technology in the transportation industry is a key task. With the rapid urbanization development process, the implementation of new urbanization construction, structural reform from the supply side, demand-side management, focus on reducing costs, complementing shortcomings, high-quality, strong services, better services to ensure the stable and healthy development of social economy . The city is transforming, urban transportation is also transforming, and the transportation system is changing from the historical and static small data analysis mode to the real-time and dynamic big data research and judgment mode.
近年来,我国城市的快速城市化建设进程和城市机动化速度不断加快,对交通***需求迅猛增长,交通***问题也日益突出,成为城市社会经济发展的瓶颈问题。如何解决困扰城市发展的交通***问题,是摆在我国城市发展面前的严峻课题。In recent years, the rapid urbanization process of cities in my country and the speed of urban motorization are accelerating. The demand for the transportation system is growing rapidly, and the problems of the transportation system are becoming increasingly prominent. How to solve the traffic system problem that plagues the development of cities is a stern subject facing the development of cities in my country.
交通***管理与控制服务指数评价体系既是交通***管理与控制的评价体系,也是交通***治理处置引导体系。作为交通***服务指数体系,能够衡量一个城市不同时期交通管理与控制水平的变化,也能够评价同一时期不同城市交通管理与控制水平的差异。此外,以交通***管理与控制服务指数分析城 市交通问题的关键症结和严重程度,以提高对症下药的治理方案科学性。作为交通***管理与控制的服务指数引导体系,它帮助交通规划、建设、管理与控制等相关政府部门建立***工程的方法,以及解决城市交通***问题的总体思路,给出解决城市交通问题的总体框架和城市交通管理与控制的发展前景,引导城市交通管理的科学化、现代化、国际化、一体化发展进程,进而引导交通***可持续发展的交通管理与控制服务体系建立。The traffic system management and control service index evaluation system is not only the evaluation system of traffic system management and control, but also the guidance system of traffic system governance and disposal. As a transportation system service index system, it can measure the changes of traffic management and control levels of a city in different periods, and can also evaluate the differences in traffic management and control levels of different cities in the same period. In addition, the transportation system management and control service index is used to analyze the key crux and severity of urban traffic problems, so as to improve the scientificity of the appropriate treatment plan. As a service index guidance system for transportation system management and control, it helps transportation planning, construction, management and control and other relevant government departments to establish system engineering methods, as well as general ideas for solving urban transportation system problems, and gives an overall solution to urban transportation problems. The framework and the development prospects of urban traffic management and control will guide the scientific, modern, international and integrated development of urban traffic management, and then guide the establishment of a sustainable traffic management and control service system for the transportation system.
交通管理与控制学科是随车辆与道路交通而生,由交通管理与交通控制两个部分构成;交通管理是对道路上的行车、停车、行人、道路使用,执行交通法规的“执法管理”,用交通工程技术措施对交通运行状况进行改善的“交通治理”统称;交通控制是依靠交通警察或采用交通信号控制设施,随交通变化特性来指挥车辆、行人的通行。从宏观上来说,交通控制是交通管理的某一表现方式,因此在现代交通管理中,交通管理与交通控制是一个有机结合的整体。交通管理与控制措施,按其是否具有法律意义,在性质上可分为两类:具有法律意义且必须强制执行的管理措施,是指在交通法规中规定的,为维护交通秩序,保障交通安全所必须的基本交通规则;用来改善交通状况的工程技术措施,这些措施本身不具有法律意义,但要使这些措施能得到有效实施,还需依靠具有法律意义的管理措施来强制执行,或依靠经济手段来诱导执行。The discipline of traffic management and control is born with vehicles and road traffic, and consists of two parts: traffic management and traffic control; traffic management is the "enforcement management" of traffic laws, parking, pedestrians, and road use, and the implementation of traffic regulations. "Traffic governance" that uses traffic engineering technical measures to improve traffic operation conditions is collectively referred to; traffic control is to rely on traffic police or use traffic signal control facilities to direct the passage of vehicles and pedestrians with the changing characteristics of traffic. From a macro perspective, traffic control is a certain expression of traffic management. Therefore, in modern traffic management, traffic management and traffic control are an organically integrated whole. Traffic management and control measures, according to whether they have legal significance, can be divided into two categories in nature: management measures that have legal significance and must be enforced refer to those prescribed in traffic regulations to maintain traffic order and ensure traffic safety Necessary basic traffic rules; engineering and technical measures used to improve traffic conditions. These measures themselves have no legal significance, but for these measures to be effectively implemented, they must also be enforced by legally meaningful management measures, or rely on Economic means to induce execution.
随着社会及小汽车工业的发展,交通管理与控制的目的也在不断变化。初期的交通管理是最基本的交通要求,即保障交通安全。随着车辆保有量的增加,道路上出现了车辆拥挤、阻塞现象,在保障交通安全的基础上,还要求交通管理与控制达到疏导交通、保障交通畅通。在采取了疏导交通之后,车辆依然在不断地增长,交通拥挤、交通安全、交通污染现象日趋严重;道路交通工程设施的建设速度总是跟不上车辆增长的速度,现有的道路交通设施的交通效率总 是有限。因此,近年来在交通管理与控制领域产生了一种新思路,即通过采用交通需求管理的方法,来控制道路上的汽车交通量需求。现代化交通管理与控制服务指数的目的是除了为保障交通安全、疏导交通、提高现有交通设施的通车效率的传统目的外,着重采取各种交通需求管理措施来减少道路上的车辆交通总量、缓解交通拥堵、保障交通安全与畅通,并降低汽车对交通环境的污染,实现采用数字量化衡量交通管理与控制服务水平以及服务模式的趋势。With the development of society and the car industry, the purpose of traffic management and control is constantly changing. The initial traffic management is the most basic traffic requirement, which is to ensure traffic safety. With the increase in the number of vehicles, vehicle congestion and congestion have appeared on the roads. On the basis of ensuring traffic safety, traffic management and control are also required to facilitate traffic and ensure smooth traffic. After adopting traffic diversion, vehicles are still growing, traffic congestion, traffic safety, and traffic pollution are becoming more and more serious; the construction speed of road traffic engineering facilities is always unable to keep up with the growth rate of vehicles. Traffic efficiency is always limited. Therefore, in recent years, a new idea has emerged in the field of traffic management and control, that is, to adopt the method of traffic demand management to control the demand for automobile traffic on the road. The purpose of the modern traffic management and control service index is to focus on adopting various traffic demand management measures to reduce the total amount of vehicle traffic on the road, in addition to the traditional purposes of ensuring traffic safety, channeling traffic, and improving the efficiency of existing traffic facilities. Alleviate traffic congestion, ensure traffic safety and smoothness, and reduce the pollution of cars to the traffic environment, and realize the trend of using digital quantitative measurement of traffic management and control service levels and service models.
交通管理与控制是一个新型的学科领域,包括交通管理、交通控制、交通诱导、交通事故、交通教育、交通执法、交通信息工程、交通大数据云计算、人工智能、交通指挥机器人、交通云机器人、深度学***等诸多方面得到反映。此外,城市交通结构的合理化,城市土地利用的调整以及管理体制、交通投资、交通规划的制定与措施均是解决交通***问题不可缺少的重要内容。在评价交通管理与控制时,必须采取多目标原则,对影响道路交通管理水平的各个方面进行定量计算和定性分析,确定评价标准和方法,综合评价整个交通管理与控制的总体水平和能力。所以,选取交通管理与控制服务指数指标体系时,既要注重交通管理效果评价,也要注重管理手段、管理过程的科学指导。Traffic management and control is a new discipline, including traffic management, traffic control, traffic guidance, traffic accidents, traffic education, traffic law enforcement, traffic information engineering, traffic big data cloud computing, artificial intelligence, traffic command robots, traffic cloud robots , Deep learning and other interdisciplinary composite comprehensive technologies, the management and control effects can be reflected in many aspects such as traffic order, traffic congestion, traffic accidents, and traffic service levels. In addition, the rationalization of the urban transportation structure, the adjustment of urban land use and the formulation and measures of management systems, transportation investment, and transportation planning are all indispensable important elements for solving the problems of the transportation system. When evaluating traffic management and control, the multi-objective principle must be adopted to quantitatively calculate and qualitatively analyze various aspects that affect the level of road traffic management, determine evaluation criteria and methods, and comprehensively evaluate the overall level and capability of the entire traffic management and control. Therefore, when selecting the index system of traffic management and control service index, it is necessary to pay attention not only to the evaluation of traffic management effects, but also to the scientific guidance of management methods and management processes.
现有的大数据环境交通管理与控制服务指数方法及***主要存在以下缺点:The existing big data environment traffic management and control service index method and system mainly have the following disadvantages:
1、当前,交通服务指数领域中通常是采用向市民发放交通出行问卷、归纳统计分析整理问卷后,来发布城市与区域交通服务指数方式进行的。这种方式存在着发放问卷调查周期长、问卷发放范围与取样比例不足、对问卷的问题回答不十分准确、不能进行连续动态对交通服务数据及时进行评价等问题。1. At present, in the field of transportation service index, the urban and regional transportation service index is released by issuing the transportation questionnaire to the citizens, summarizing the statistical analysis and sorting out the questionnaire. This method has the problems of long questionnaire survey cycle, insufficient questionnaire scope and sampling ratio, inaccurate answers to questionnaires, and continuous and dynamic evaluation of transportation service data.
2、在城市道路交通指数单一方面,虽然有了个别的道路交通指数发明,但是对于城市交通体系整体服务指数上,缺乏全面性、***性的总体评价与总体描述城市交通运输体系服务的一体化、可量化、可视化的交通管理与控制服务指数方法发明提出,明显缺乏全面评价城市交通与区域交通服务指数的方法与***。2. In the single aspect of the urban road traffic index, although there are individual road traffic index inventions, the overall service index of the urban transportation system lacks a comprehensive and systematic overall evaluation and overall description of the integration of urban transportation system services The invention of a method for the management of traffic management and control service index based on quantization, quantification and visualization clearly proposes that there is obviously a lack of a method and system for comprehensive evaluation of urban traffic and regional traffic service index.
3、国外发达国家对城市交通服务水平的评价进行了***和周密的研究,形成了较完整的体系,但是构建基于交通大数据实时发布交通管理与控制服务指数的方法与***模式还属空白。在这些国家中城市交通服务水平的指标体系已经成为编制城市交通规划的重要依据,也是政府部门为交通运输企业制订运营任务和目标的工具,更是公众市民对城市交通***服务进行监督和评价标准的手段。3. The developed countries have carried out systematic and thorough research on the evaluation of urban traffic service levels, forming a relatively complete system, but the method and system model for building real-time traffic management and control service index based on traffic big data is still blank. In these countries, the index system of urban transportation service level has become an important basis for the preparation of urban transportation planning, and it is also a tool for government departments to formulate operational tasks and goals for transportation enterprises. It is also a standard for public citizens to supervise and evaluate urban transportation system services. s method.
4、国内目前依然缺乏***地评价城市交通服务水平的指标体系,《城市道路交通规划设计规范》中有关城市交通的章节,其内容侧重于交通设施规划,涉及的指标也多为设施配置与建设指标,并不是城市交通运行服务指标,特别是当前城市交通转型期就更不适用。也有学者在研究城市交通发展水平方面,提出综合评价指标体系时提出一些的运营服务水平指标,然而这些服务水平指标的提及并没有进行与选择交通方式的行为决策过程结合起来,缺乏交通行为(交通行为的运作、交通行为的通道、交通行为的控制与保障)的分析研判,也没有涉及到城市交通服务水平指标等级的划分与确定,更没有建立交通大数据环境下实时发布交通管理与控制服务指数的方法与***。4. At present, there is still a lack of an index system for systematic evaluation of urban transportation service levels in China. The chapter on urban transportation in the "Code for Design of Urban Road Transportation Planning" focuses on transportation facility planning, and the indicators involved are mostly facility allocation and construction. Indicators are not indicators of urban transportation operation services, especially in the current urban transportation transformation period. Some scholars have put forward some operational service level indicators when they put forward a comprehensive evaluation index system in the study of urban transportation development level. However, the mention of these service level indicators has not been combined with the behavioral decision-making process of selecting transportation methods, and lacks traffic behavior ( The analysis and judgment of the operation of traffic behaviors, the channels of traffic behaviors, the control and guarantee of traffic behaviors, nor the classification and determination of the index level of urban traffic service levels, nor the establishment of real-time traffic management and control under the traffic big data environment. Method and system of service index.
综上所述,国内外在大数据环境交通管理与控制服务指数方法及***上,尚未见到完整的、一体化的、可量化的、可视化的发明记载。我国在城市交通服务水平指标体系研究方面和基于交通大数据交通管理与控制服务指数的方 法相对滞后的状况,严重影响了城市交通***建设和健康发展,特别是公众出行对城市交通***服务水平监督的需求满足。因此,迫切需要提供可量化、可视化指标体系的方法对交通***服务进行分析与研判。In summary, at home and abroad, there has not been a complete, integrated, quantifiable, and visual record of inventions in the big data environment traffic management and control service index method and system. The relatively lagging situation in the research on the index system of urban traffic service level and the method of traffic management and control service index based on traffic big data in China has seriously affected the construction and healthy development of the urban traffic system, especially the public travel supervision of the urban traffic system service level The needs are met. Therefore, there is an urgent need to provide a quantifiable and visual indicator system to analyze and judge traffic system services.

针对传统数据中心架构面临的主要挑战以及对数据中心的理解,分布式云平台数据中心的总体架构设计主要包括两类数据中心:第一是策略与备份节点类数据中心,第二是分布式业务节点类数据中心。在物理上两者可以合设,也可以分开。In response to the main challenges faced by the traditional data center architecture and the understanding of the data center, the overall architecture design of the distributed cloud platform data center mainly includes two types of data centers: the first is the strategy and backup node data center, and the second is the distributed business Node data center. Physically, the two can be co-located or separated.

步骤300:基于区域交通与城市交通大数据云计算平台,根据交通管理与控制服务指数指标关联与评价进行建模,形成对交通***服务水平和服务能力的评价。Step 300: Based on the regional transportation and urban transportation big data cloud computing platform, modeling is performed according to the correlation and evaluation of the traffic management and control service index indicators to form an evaluation of the service level and service capability of the transportation system.
在步骤300中,交通管理与控制服务指数评价指标体系主要是建立在交通管理服务指数方面和交通控制服务指数两个方面进行关联设计,两个方面的服务指数评价指标分别建立在交通管理与控制领域内容。交通管理与控制服务指数评价的指标体系种类设计,关系到交通管理与控制服务的有效性和服务水平的科学性评价,基于交通管理与控制学科的专业性评价指标含义,建立基于交通大数据云计算的服务指数评价指标体系,详见如下表所示。In step 300, the traffic management and control service index evaluation index system is mainly based on the traffic management service index and the traffic control service index. The two aspects of the service index evaluation index are based on traffic management and control. Field content. The design of the index system of traffic management and control service index evaluation is related to the scientific evaluation of the effectiveness and service level of traffic management and control services. Based on the meaning of the professional evaluation indicators in the discipline of traffic management and control, the establishment of a traffic-based big data cloud The calculated service index evaluation index system is shown in the following table.
交通管理与控制服务指数评价指标体系关联结构设计,基于这一评价指标体系关联结构,可以建立交通管理与控制服务指数可量化、可视化的评价指标体系。交通管理与控制服务指数评价模型和评价方法是在交通***服务指数评价指标体系建立后,基于交通大数据云计算平台,建立交通管理与控制服务数评价指标与交通大数据的匹配关联性评价建模,形成对交通***服务水平和服务能力的评价方法,这是衡量交通***管理与控制高品质提升的可量化、可视化重要方法,主要包括多目标决策方法、层次分析法、广义函数法及评价方法的应用与选择。上述的交通管理与控制服务指数评价的指标体系种类内容中,没有哪一个指标能够单独作为评价整个交通***的依据。因此,还需要建立一个综合性指标,它能够全面地反映交通***状况,以利于各个城市交通***之间或同一城市交通***不同时期之间比较。多目标决策是具有两个以上的决策目标,并且需用多种标准来评价和优选方案的决策。大多是交通管理与控制服务指数评价决策中最重要的战略决策。例如一个重大交通***项目的决策,就要考虑经济效益、社会效益、安全施工与环境保护等多方面的目标,需要用多种标准进行评价方案和优选方案。其特点是:第一,由于目标和标准的多样性,造成方案比较优劣的工作比较复杂,难以找到使所有目标达到最佳的方案;第二,决策过程是从淘汰较差方案开始,在剩下的方案中选取满意的方案,用满意标准取代最优标准。多目标决策法的基本原理:从人们在多目标条件下合理进行决策的过程和机制,多目标决策的理论主要有:多目标决策过程的分析和描述;冲突性的分解和理想点转移的理论;多属性效用理论;需求的多重性和 层次性理论等,它们是构成多目标决策分析方法的理论基础。在多目标决策中,有一部分方案经比较后可以淘汰,称为劣解;但还有一批方案既不能淘汰,又不能互相比较,从多目标上考虑又都不是最优解,称为“非劣解”(或“有效解”、“帕累托解”)。决策分析是在交通***规划、建设、管理、运行阶段为解决当前或未来可能发生的问题,在若干可选的方案中选择和决定最佳方案的一种分析过程。在交通经济***的研究管理与控制过程中我们所面临的交通***决策问题常常是多目标的,例如我们在研究交通运输组织生产过程的组织决策时,既要考虑交通***的运输能力最大,又要使运输服务质量高,运输成本低等。这些目标之间相互作用和矛盾,使决策过程相当复杂,使决策者常常很难轻易作出决策。这类具有多个目标的决策总称就是多目标决策,多目标决策方法现已广泛地应用于交通运输工程、智能交通工程等领域。The associative structure design of the evaluation index system of the traffic management and control service index. Based on this associative structure of the evaluation index system, a quantifiable and visual evaluation index system of the traffic management and control service index can be established. The traffic management and control service index evaluation model and evaluation method is based on the establishment of the traffic system service index evaluation index system, based on the traffic big data cloud computing platform, to establish a matching correlation evaluation evaluation index of traffic management and control service number and traffic big data. Model to form an evaluation method for the service level and service capability of the transportation system. This is an important method to measure the high-quality improvement of transportation system management and control. It mainly includes multi-objective decision-making methods, analytic hierarchy process, generalized function method and evaluation. Application and selection of methods. Among the types of index systems for the above traffic management and control service index evaluation, no single index can be used as the basis for evaluating the entire transportation system. Therefore, it is also necessary to establish a comprehensive indicator that can comprehensively reflect the status of the transportation system, so as to facilitate comparison between various urban transportation systems or between different periods of the same urban transportation system. Multi-objective decision-making is a decision that has more than two decision-making goals, and needs to use a variety of criteria to evaluate and optimize the program. Most of them are the most important strategic decisions in traffic management and control service index evaluation decisions. For example, in the decision-making of a major transportation system project, it is necessary to consider the economic, social benefits, safe construction and environmental protection and other objectives. It is necessary to use a variety of criteria for evaluation and optimization. Its characteristics are: first, due to the diversity of goals and standards, the work of comparing the advantages and disadvantages of the plan is more complicated, and it is difficult to find the best plan for all goals; second, the decision-making process starts from eliminating the poorer plan. Among the remaining plans, select the satisfactory plan and replace the optimal standard with the satisfactory standard. The basic principle of multi-objective decision-making method: from the process and mechanism of people making decisions rationally under multi-objective conditions, the theory of multi-objective decision-making mainly includes: analysis and description of multi-objective decision-making process; the theory of conflicting decomposition and ideal point transfer ; Multi-attribute utility theory; multiplicity and hierarchical theory of demand, etc., which constitute the theoretical basis of the multi-objective decision analysis method. In multi-objective decision-making, a part of the schemes can be eliminated after comparison, which is called inferior solution; but there are a batch of schemes that can neither be eliminated or compared with each other, nor considered optimal in terms of multi-objectives, called "non- Inferior solution" (or "effective solution", "Pareto solution"). Decision analysis is an analysis process that selects and decides the best one among several alternatives in order to solve the current or future problems in the planning, construction, management and operation of the transportation system. The transportation system decision-making problems we face in the research management and control process of the transportation economic system are often multi-objective. For example, when we study the organization and decision-making of the transportation organization production process, we must consider the maximum transportation capacity of the transportation system, and It is necessary to make transportation services of high quality and low transportation costs. The interaction and contradiction between these goals make the decision-making process quite complicated and make it difficult for decision-makers to make decisions easily. This type of decision-making with multiple objectives is generally called multi-objective decision-making. Multi-objective decision-making methods are now widely used in transportation engineering, intelligent transportation engineering and other fields.
多目标决策的原则:交通管理与控制服务指数评价的多目标决策原则是在多目标决策实践中应遵循的行为准则。主要包括:The principle of multi-objective decision-making: The multi-objective decision-making principle of traffic management and control service index evaluation is the code of conduct that should be followed in the practice of multi-objective decision-making. mainly includes:
在满足决策需要的前提下,尽量减少交通管理与控制服务指数评价目标个数;可采用剔除从属性目标,并通过交通大数据关联性匹配把类似的目标合并为一个目标,或者把那些只要求达到起码标准而不要求达到最优的次要目标降为约束条件;以及通过同度量求和、求平均值或构成综合函数的方法,用综合评价指标来代替单项评价指标的办法达到目的。Under the premise of meeting the needs of decision-making, try to reduce the number of evaluation targets of traffic management and control service index; you can use the elimination of dependent targets, and merge similar targets into one through traffic big data correlation matching, or combine those that only require Reaching the minimum standard without requiring the achievement of the optimal secondary goal is reduced to constraints; and the method of summing, averaging or composing a comprehensive function with the same measure, using a comprehensive evaluation index instead of a single evaluation index to achieve the goal.
按照交通管理与控制服务指数评价目标的轻重缓急,决定目标的取舍。为此,就要将目标按重要程度排列出一个顺序,并规定出重要性系数,以便在选优决策时有所遵循。According to the priorities of the traffic management and control service index evaluation goals, the choice of goals is determined. To this end, it is necessary to arrange the goals in order of importance and specify the importance coefficients so that they can be followed in the selection of optimal decisions.
对交通管理与控制服务指数评价相互矛盾的目标,应以总目标为基准进行协调,力求对各目标全面考虑,统筹兼顾。For the conflicting goals of the traffic management and control service index evaluation, the overall goal should be used as the basis for coordination, and all goals should be considered in a comprehensive manner, taking into account the overall consideration.
交通管理与控制服务指数评价模型:当交通管理与控制服务指数评价决策对象具有多个评价目标时,从若干可行方案(也称解)中,选择一个满意方案(解)的决策方法。进行多目标决策时,根据服务指数评价事前确定的评价标 准,从一组非劣解中,通过“辨优”和“权衡”找出一个令人满意的解。Traffic management and control service index evaluation model: When the traffic management and control service index evaluation decision-making object has multiple evaluation objectives, from a number of feasible solutions (also called solutions), choose a satisfactory solution (solution) decision method. When making multi-objective decision-making, according to the evaluation criteria determined in advance by the service index evaluation, from a set of non-inferior solutions, find a satisfactory solution through "distinguishing" and "trade-off".
多目标决策问题的某一可行方案与其他可行方案两两比较时,其结果有三种可能:第一,所有目标都是最优的方案,称为完全最优解,这种情况极少出现;第二,所有目标都是最劣的方案,称为劣解,立即可以淘汰;第三,目标有优有劣,既不能肯定方案为最优,也不能立即予以淘汰,这种方案称为非劣解,又称有效解或帕雷托最优解。多目标最优问题的数学模型为:设交通管理与控制服务指数评价***有m个目标f1(x),f2(x),...,fm(x),要求评价由n个变量组成的方案x=(x1,x2,...,xn)T,如果这些目标都要求最大(或最小),并要求解满足约束条件集合R,则数学模型可表达成如下形式:When a feasible solution of a multi-objective decision-making problem is compared with other feasible solutions in pairs, the result has three possibilities: First, all goals are the optimal solution, called the complete optimal solution, which rarely occurs; Second, all goals are the worst solutions, called inferior solutions, and can be eliminated immediately; third, the goals have advantages and disadvantages, and neither can be sure that the solution is optimal, nor can it be eliminated immediately. Inferior solutions, also known as effective solutions or Pareto optimal solutions. The mathematical model of the multi-objective optimal problem is: suppose that the traffic management and control service index evaluation system has m objectives f1 (x), f2 (x), ..., fm (x), and requires evaluation of n variables Scheme x = (x1, x2, ..., xn) T, if these goals require maximum (or minimum), and the solution is required to satisfy the set of constraints R, then the mathematical model can be expressed as follows:
式(1)中F(x)=(f1(x),f2(x),...,fm(x))为目标向量。In formula (1), F(x)=(f1(x), f2(x), ..., fm(x)) is the target vector.
多目标决策方法应用模式分析:在大数据环境交通管理与控制服务指数方法及***发明中,用于多目标交通管理与控制服务指数决策的综合评价方法很多,如层次分析法、单纯矩阵评价法、模糊分析法、广义函数法、加权相对偏差距离最小法、集合分析法、模糊综合评判发、主成分分析法、因子分析法等,各种方法所需要的前提条件不同,各自的用途也不同。本发明中只是介绍相关理论方法的应用模式,具体应用时可以结合不同城市交通***的特点以及同一城市交通***不同时期的管理与控制服务指数的不同评价模式进行选择。Multi-objective decision-making method application mode analysis: In the invention of the big data environment traffic management and control service index method and system, there are many comprehensive evaluation methods for multi-objective traffic management and control service index decision-making, such as AHP and simple matrix evaluation method , Fuzzy analysis method, generalized function method, weighted relative deviation distance minimum method, set analysis method, fuzzy comprehensive evaluation, principal component analysis method, factor analysis method, etc., various methods require different prerequisites, and their respective uses are also different . The present invention only introduces the application mode of related theoretical methods. In specific application, it can be selected by combining the characteristics of different urban transportation systems and the different evaluation modes of the management and control service index of the same urban transportation system at different periods.
层次分析法用于建立交通管理与控制服务指数评价决策体系的分层评价结构,并利用服务指数评价指标与交通大数据关联性匹配所得到的判断矩阵求出各项评价指标的权重。The analytic hierarchy process is used to establish the hierarchical evaluation structure of the traffic management and control service index evaluation decision system, and the weight of each evaluation index is obtained by using the judgment matrix obtained by matching the correlation between the service index evaluation index and the traffic big data.
单纯矩阵评价法是利用服务指数评价指标与交通大数据关联性匹配所得到的判断矩阵确定各个城市交通***服务指数评价指标得分,用于可量化的定性指标确定。The simple matrix evaluation method is to use the judgment matrix obtained by matching the correlation between the service index evaluation index and the traffic big data to determine the score of each urban transportation system service index evaluation index, which is used to determine the quantifiable qualitative index.
模糊分析法是利用判断矩阵对各个城市交通管理与控制服务指数评价指 标排序,实际上是前两种方法的简化处理。The fuzzy analysis method is to use the judgment matrix to rank the evaluation indicators of each urban traffic management and control service index, which is actually a simplified treatment of the first two methods.
广义函数法是在已知权重和所有城市交通管理与控制服务指数的各项指标值后,再经过分级标定,把指标值转化为得分,然后采用加权求和的方法得到总分。The generalized function method is to know the weights and all the index values of all urban traffic management and control service indexes, and then pass the grading calibration to convert the index values into scores, and then use the weighted sum method to get the total score.
加权相对偏差距离最小法是在已知权重和所有城市交通管理与控制服务指数评价的各项指标值后,构造“虚拟最佳城市交通***”,以各个实际城市与“虚拟最佳城市交通***”的加权相对偏差距离大小来判断各个城市交通管理与控制服务指数的优劣。The weighted relative deviation distance minimum method is to construct a "virtual optimal urban transportation system" after knowing the weights and all index values of all urban traffic management and control service index evaluations. The weighted relative deviation distance is used to judge the pros and cons of each urban traffic management and control service index.
集合分析法也是在已知交通管理与控制服务指数评价指标值矩阵和权重后,由排序矩阵、指数矩阵得到城市交通管理与控制服务指数的排序。The ensemble analysis method also obtains the ranking of the urban traffic management and control service index from the ranking matrix and the index matrix after the evaluation index value matrix and weights of the traffic management and control service index are known.
模糊综合评判法是依次确定因素(评价指标)集、判断集,并通过单因素评判得到模糊矩阵,用模糊矩阵与权重向量共同得到交通管理与控制服务指数综合评判结果。The fuzzy comprehensive evaluation method is to determine the factor (evaluation index) set and judgment set in turn, and obtain the fuzzy matrix through single factor evaluation, and use the fuzzy matrix and the weight vector to obtain the comprehensive evaluation result of the traffic management and control service index.
主成分分析法和因子分析法都是在已知多个样本数据条件下,计算各个指标的相关矩阵,得到主成分或主因子,从而确定交通管理与控制服务指数综合评价指标的计算,因子分析法是主成分分析法的推广。Principal component analysis method and factor analysis method both calculate the correlation matrix of each indicator under the condition of known multiple sample data to obtain the principal component or principal factor, so as to determine the calculation of the comprehensive evaluation index of traffic management and control service index, factor analysis method It is the promotion of principal component analysis.

城市交通实时动态信息发布的顺序图和协作图统称交互图,它们用于分析刻画***用例实现中对象间的动态交互和消息传递,帮助识别类、职责,并在协作者之间分配职责,还用于识别接口和抽象类。The sequence diagrams and collaboration diagrams for the release of real-time dynamic information of urban transportation are collectively referred to as interaction diagrams. They are used to analyze the dynamic interaction and message passing between objects in the realization of the use cases of the portrayal system, help to identify classes and responsibilities, and distribute responsibilities among collaborators. Used to identify interfaces and abstract classes.
顺序图显示对象如何通过交互来执行部分或全部用例的行为,一个或多个顺序图可以阐述用例的对象交互,顺序图典型的组织方式是:一个顺序图用于主要的事件流,一个顺序图用于用例的每个独立子流程或备选流。顺序图对于设计人员而言尤其重要,因为顺序图阐明了对象在流程中的角色,为确定类职责和接口提供了基础输入信息。与协作图不同,顺序图包括了按时间排定的序列,而不包括对象关系。顺序图和协作图表达相似的信息,但显示方式不同。顺序图显示了消息的明确序列,需要对消息的时间排序进行可视化建模时,顺序图尤其适用。如果需要分析交互中的实例之间的结构关系,则使用协作图。使用顺序图设计用例,主要识别平台相关的设计类、属性和方法。Sequence diagrams show how objects perform some or all of the use cases through interaction. One or more sequence diagrams can illustrate the object interactions of use cases. The typical organization of sequence diagrams is: a sequence diagram for the main event flow, a sequence diagram Each independent sub-process or alternative flow for use cases. Sequence diagrams are especially important for designers because sequence diagrams clarify the role of objects in the process and provide basic input information for determining class responsibilities and interfaces. Unlike collaboration diagrams, sequence diagrams include chronological sequences, but not object relationships. Sequence diagrams and collaboration diagrams express similar information, but they are displayed differently. The sequence diagram shows a clear sequence of messages. The sequence diagram is especially suitable when you need to visually model the chronological order of messages. If you need to analyze the structural relationship between the instances in the interaction, use a collaboration diagram. Use sequence diagrams to design use cases that primarily identify platform-related design classes, attributes, and methods.
当查看交通拥挤地图用例时,用户通过页面请求查看交通拥挤地图。QueryTrafficMapAction向MapProcessor发出地图绘制请求信息,MapProcessor首先用SEConnection连接GEODatabase获取地图绘制基本信息,然后调用ArcIms的一些API将地图绘制出来并显示在display_map.jsp页面上。用户可以通过放大缩小来查看某一路段的详细信息,也可以通过选定某一路段查看详细信息。如果通过选定某一路段来查看,则MapProcess根据所选位置的X、Y坐标通过用SEConnection连接GEODatabase来进行LinkID的匹配,然后QueryTrafficMapAction通过ServiceLocator获取对应的Home接口,由该Home接口产生Remote实例,调用该实例的某一方法即:根据该LinkID得到和所选路段所有相关的Link,通过某算法计算该路段的当前平均车速、标准车速和预测车速。MapProcessor通过ArcIMS将所选路段详细信息在display_road_detailed_into.jsp上发布出来。将查看交通拥挤地图的基本流分为两部分:生成交通拥挤地图和查看某路段动态交通信息。When viewing the traffic congestion map use case, the user requests to view the traffic congestion map through the page. QueryTrafficMapAction sends a map drawing request message to MapProcessor. MapProcessor first uses SEConnection to connect to the GEODatabase to obtain basic map drawing information, and then calls some ArcIms APIs to draw the map and display it on the display_map.jsp page. The user can view detailed information of a certain road segment by zooming in or out, or view detailed information by selecting a certain road segment. If you check by selecting a certain road segment, MapProcess matches the LinkID by using SEConnection to connect to the GEODatabase according to the X and Y coordinates of the selected location, and then QueryTrafficMapAction obtains the corresponding Home interface through ServiceLocator, and the Remote instance is generated by the Home interface. Calling a method of this instance is to obtain all related links with the selected road segment according to the LinkID, and calculate the current average speed, standard speed and predicted speed of the road segment through an algorithm. MapProcessor publishes the detailed information of the selected road segment on display_road_detailed_into.jsp through ArcIMS. The basic flow of viewing traffic congestion maps is divided into two parts: generating traffic congestion maps and viewing dynamic traffic information of a road segment.
城市交通实时动态信息发布的协作图有对象和参与者实例,以及链接和消息(描述对象是如何相关和交互的),***协作图描述对象如何通过互相发送消息进行通信,描述参与的各对象的行为,在用例实现中通常为用例事件流的每个变体设计一个协作图。协作图用于显示对象如何交互以执行特定用例或一部分用例的行为,使用协作图和序列图来定义和阐明对象角色,这些对象执行特定的用例事件流,它们是用于确定类职责和接口的主要信息源。与序列图不同,协作图显示了对象之间的关系,序列图和协作图表达了类似的信息,但以不同方式显示这些信息。协作图显示了对象之间的关系,更适用于理解给定对象上的所有效果,更适用于过程设计。由于协作图的形式,它更适用于分析活动,适用于描述较少量对象的较简单交互。Collaboration diagrams published by the real-time dynamic information of urban transportation include objects and participant instances, as well as links and messages (to describe how the objects are related and interacted with). System collaboration diagrams describe how objects communicate by sending messages to each other, and describe the various objects involved. Behavior, in the use-case realization usually design a collaboration diagram for each variant of the use-case event flow. Collaboration diagrams are used to show how objects interact to perform a specific use case or part of the use case behavior. Collaboration diagrams and sequence diagrams are used to define and clarify object roles. These objects perform specific use case event flows. They are used to determine class responsibilities and interfaces. The main source of information. Unlike sequence diagrams, collaboration diagrams show the relationship between objects. Sequence diagrams and collaboration diagrams express similar information, but display the information in different ways. Collaboration diagrams show the relationship between objects, and are more suitable for understanding all the effects on a given object, and more suitable for process design. Due to the form of the collaboration diagram, it is more suitable for analysis activities and for describing simpler interactions with a smaller number of objects.
***设计主要采用协作图识别类、属性、方法和关系,在协作者之间分配职责,具体设计职责的实现方式,识别关键接口并进一步设计出对应业务组件。当查看交通拥挤地图用例实现时,用户直接访问交通拥挤地图页面,通过 ActionServlet访问MapProcessor接口,发布拥挤地图,需要查询动态交通信息时,通过ServiceLocator对象,查找到交通拥挤地图业务组件的Home接口,进行初始化,然后通过获取交通拥挤地图组件的Remote接口获得相关服务。System design mainly uses collaboration diagrams to identify classes, attributes, methods, and relationships, distribute responsibilities among collaborators, implement specific design responsibilities, identify key interfaces, and further design corresponding business components. When viewing the traffic congestion map use case implementation, the user directly accesses the traffic congestion map page, accesses the MapProcessor interface through the ActionServlet, and publishes the congestion map. When querying dynamic traffic information, the ServiceLocator object is used to find the home interface of the traffic congestion map business component. Initialize, and then obtain related services by obtaining the Remote interface of the traffic congestion map component.
对于每个用例实现,可能有描绘其参与类的一个或多个类图,***设计对每个用例实现识别出了具体的类和接口,并按照MVC设计模式,对各个参与类定义属性和方法,结合具体实现技术对类的属性和操作进行了定义。类图显示为一组(静态的)声明的模型元素(例如类、包以及它们的关系),以图的方式互相连接。可以将类图组织成包(并由包所拥有),显示特定包中的相关内容。除了表示类、属性和职责,类图中还必须对类之间的关系加以描述。For each use case implementation, there may be one or more class diagrams depicting its participating classes. The system design identifies specific classes and interfaces for each use case implementation, and defines attributes and methods for each participating class according to the MVC design pattern , Combined with the specific implementation technology to define the attributes and operations of the class. Class diagrams are displayed as a set of (static) declared model elements (such as classes, packages, and their relationships), connected to each other in a graphical manner. Class diagrams can be organized into packages (and owned by packages), showing related content in a specific package. In addition to representing classes, attributes, and responsibilities, class diagrams must also describe the relationships between classes.
