Research On The Method Of Dynamic Traffic Guidance Location In Urban Area

As an important indicator to measure the healthy development of cities,the inevitable requirement of rational allocation of urban resources,the realization of intelligent transportation promotes the stable development of modern cities,and urban dynamic induction as an important part of intelligent transportation has a significant role in alleviating traffic congestion in modern cities.There are few studies on dynamic traffic guidance placement in China.The current dynamic traffic guidance placement is based on the experience of traffic managers.The theoretical research is mostly considering a single layout model based on road traffic conditions,Therefore,this paper proposes to consider the method of dynamic traffic guidance placement in urban areas from the perspective of drivers.The main research contents of the paper include the following:(1)Obtain the driver's personal information data through SP survey,the evaluation of the effect of urban dynamic traffic guidance and the driver's route selection behavior data under the guidance information,and obtain the influencing factors of the driver's route selection behavior,and analyze many factors.The relationship with the driver's routing behavior.(2)Take the probability of the driver changing the path under the influence of the road information as the breakthrough point of the study,study the behavior of the driver changing the path according to the road information,and establish a driver to change the path The model with the maximum ratio finally obtains a parameter equation for the driver to change the path frequency due to the induction and measure the frequency by regression analysis of the model on the SP survey data.(3)Taking a county in Shandong Province as an example,a case verification method based on the driver route selection model is verified.The calculation example collects the basic data required for the simulation,VISSIM simulation separately simulates the presence or absence of dynamic induction,and compares the improvement effect of road network traffic operation with different induction compliance rates under congestion,thereby verifying the feasibility of the location method.
