By the adoption of the method, the timing on crossing traffic signals is simple and visual, and the operation is facilitated.
Description
Technical field
The invention belongs to intelligent transportation field, particularly a kind of method that is used for the crossing traffic signal timing dial of urban traffic signal control system.
Background technology
Traffic signal control system is the basic application of intelligent transportation system (ITS) in traffic administration work, also is the most direct, most basic application system in the municipal intelligent traffic control system.
System design is according to city road network structure and traffic flow distribution situation; With rationalization's traffic flow, improve urban highway traffic infrastructure, the Modern Traffic consciousness that improves traffic participant is prerequisite; Real time monitoring, detection, control, coordination are carried out in traffic flow in the control area, and the traffic of improving effectively in the control area is the control of target traffic signals.Through traffic signals control, under the unsaturation transportation condition, reduce vehicle ' and incur loss through delay, reduce the red parking number of times, shorten the running time of vehicle in road network, improve the whole traffic capacity of road network; Under saturated transportation condition, traffic flow is advanced in order, the shunting vehicle is alleviated and is stopped up.It improves road passage capability to road improvement safety, reduces energy consumption and environmental pollution and has played crucial effect.
The main control parameters of traffic signals control has three: cycle, split and phase differential.
Cycle is meant that the various light colors of signal lamp show the time that circulation is used, i.e. red light amber light and green light three's time sum, and unit is second.In general, the cycle with the value of signal lamp between 36 seconds to 2 minutes, if the cycle is too short; The phenomenon that then possibly block up, the vehicle that just can not guarantee several directions is smoothly through the intersection, if the cycle is oversize; Then can cause the wagon flow stand-by period of this direction to prolong and cause being discontented with of driver; Therefore, cycle duration is the key factor of decision traffic control effect, is the main research object of signal timing dial design.Correct Cycle Length should be: the green time of a direction just makes this direction porch wait for that fleet's clearance finishes.
Split is promptly several in the ratio formula of Effective Green Time duration and the cycle duration of a signal phase to be split.The size of split has directly influenced the vehicle formation length and the vehicle stand-by period at crossing, through the green time (split) of each vehicle flowrate direction of rational distribution, just can effectively reduce the vehicle delay of all directions, the stand-by period.
Sometimes also be referred to as " time difference "; Phase differential mainly is to the controlled variable of a plurality of crossings of adjacency, as when line traffic control is carried out in a series of crossings, makes the signal lamp of adjacent intersection show same light color with it; Not as making it stagger some to guarantee quick and smooth the passing through of vehicle; Here " staggering " is phase differential, sees that from definition phase differential can be divided into absolute phase difference and relative phase difference; See that from its basic classification mode phase differential can be divided into preferential phase differential mode peace equiphase difference mode again.
Traffic signals control timing scheme configuration method generally is employed in the dialog box through traditional input method configuration such as list box, edit box and text box traffic signals controlling schemes; This method can only dispose at crossing, a crossing, can not adapt to the demand of traffic control far away.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
To above-mentioned existing in prior technology problem and shortage, the purpose of this invention is to provide a kind of method of the method configuration crossing traffic signal timing dial with time space graph, the timing of its oral sex messenger that satisfies the need is succinctly directly perceived, is convenient to operation.
For realizing above-mentioned purpose, the present invention can adopt following technical scheme with the method for the method configuration crossing traffic signal timing dial of time space graph:
A kind of method of the method configuration crossing traffic signal timing dial with time space graph provides time space graph, this sequential chart with the time as horizontal ordinate, with the distance between the adjacent crossing of road as ordinate; Each crossing is provided with a timing bar, and through the allotment phase lengths, the change cycle makes the average velocity of up-downgoing reach actual demand; Period figure is provided, and the period, figure was divided into one day some periods in chronological order, in the different periods, adopted various signals timing scheme, pressed the time situation of change with the reflection magnitude of traffic flow.
The method of the method configuration crossing traffic signal timing dial with time space graph disclosed by the invention only need be allocated phase sequence timing length, phase differential through the dilatory mode of mouse during configuration timing scheme, increases the period of intersection through double-clicking mouse.Through the allotment phase lengths, the change cycle makes the average velocity of up-downgoing reach actual demand, and this adjacent intersection can be realized the control coordinated, and its interface is succinctly directly perceived, is convenient to operation.
