Description

A kind of urban traffic signal controls operational diagnostics system
Technical field
The invention belongs to technical field of traffic signal control, it is mainly used in and Controlling Traffic Signals in Urban Roads system is transported Science diagnosis and the assessment of row state and effect, at the same time as Traffic Engineering student experimenting educational aid.
Background technology
Urban traffic signal controls as the core means alleviating crossing congestion, raising traffic flow safety, in traffic system Very crucial effect is played in system.On the one hand, the signal control strategy that it passes through to optimize improves bus capacity, reduces and prolong Between mistaking;On the other hand, it can ensure the safety of vehicle and pedestrian by key parameter during adjustment signal Phase-switching. Therefore, the quality of whistle control system is directly connected to safety and the efficiency of roadnet.
However, in real City road traffic system runs, several situations are of common occurrence below:Green light period no car By but other direction queue up longer;Close to an end the vehicle that the vehicle constantly passing through begun through with other direction in green light Clash;Pedestrian makes a dash across the red light because the waiting time is long;When pedestrian goes to road central authorities, pedestrian signal terminates and to car Begin through etc..The generation of the above phenomenon none be not that whistle control system runs and improper causes.Its main cause There are following several respects:
1st, the whistle control system of current China each big city use, mainly based on external, has indiscriminately imitated foreign system fortune Row mode and have ignored its suitability because there is larger difference in domestic and international traffic flow, especially domestic non-motor vehicle and row People's ratio is higher;
2nd, the domestic selection to modes various in whistle control system and parameter is often alternatively sentenced with Heuristicses Disconnected foundation, lacks theories integration;
3rd, after whistle control system runs longer one period, its system operation measured value exists necessarily with setting theoretical value Deviation, but domestic still lack existing signal is controlled run truly effectively, objectively diagnosis and evaluation system.
In addition, the evaluation traditionally traffic signal control system operational factor and benefit being carried out, no matter in evaluation side Still all there are some defects in terms of evaluation index in formula aspect.
In terms of evaluation method, traditional evaluates the direct observation mainly carrying out scene in intersection, by system The traffic flow data at meter scene is analyzed and evaluated.This evaluation method feasibility is not high, needs to put into substantial amounts of manpower and materials Cost carries out field test, cumbersome and time consuming.In addition, this evaluation method is normally only the running status to semaphore entering Can row assessment meet current traffic flow environment, especially under complicated transportation condition it is impossible to evaluate signal timing plan (For example bus signals are preferential)The real-time of the situation of the running of traffic control system and phase information and Rationality Assessment aspect There is exceptional hardship.If more importantly directly tested at the scene, a little error may cause the big congestion of traffic, very To initiation vehicle accident.
In terms of evaluation index, traditionally mainly pass through vehicles average delay, stop frequency and queue length etc. and refer to Mark weighs integrative design intersection effect.However, the index such as vehicles average delay itself compares difficult survey, the calculated results are serious Real-valued error is big.In addition, these index one side existing can not reflect intersection traffic stream running status comprehensively, exactly;Separately On the one hand these indexs only only account for the result that signal controls operation, consider to lead to the middle control parameter of these results Quality.
Content of the invention
Based on above-mentioned situation, it is an object of the invention to proposing a kind of urban traffic signal to control operational diagnostics system, with The Traffic flow detecting data under traffic signalization and signal timing dial data can be read in real time, then it is carried out objective, complete Face, effective diagnostic evaluation, and provide intuitively diagnostic result for manager, thus being conducive to manager to regulate and control and improving existing Control mode signal and systematic parameter, realize the maximizing the benefits of road traffic system.
