Research On The Optimization Plan Of Signal Timing In The Urban District Of Urumqi

With the rapid economic development of Urumqi,the number of motor vehicles has increased rapidly,traffic at urban intersections has increased significantly,and traffic jams at intersections frequently appear.Faced with the changing demands of people and vehicles,the signal timing of major intersections in the urban area is not adjusted in time,and the traffic organization planning is unreasonable,resulting in a decrease in traffic order and efficiency.For the fast-growing city of Urumqi,based on the existing road construction and traffic demand distribution,this is a very crucial issue to be solved.There is an urgent need to use new technologies and new methods of intelligent transportation to deal with urban traffic management,especially traffic organization and traffic signal management.First of all,the paper is based on the several source traffic data of social vehicles,public transportation vehicles,rapid transit,rail transit,etc.of the Urumqi City Transportation Comprehensive Management Platform,exploring deeply of the traffic congestion points from the express road network,primary and secondary road network,key regional road network traffic congestion point;traffic congestion evolution process(time level,spatial level),key congestion points and key congested road sections.Secondly,it analyzes and selects the general light management ideas,goals and analysis indicators,and elaborates the elaborate management ways.supported the investigation of basic information and current traffic conditions,the regional traffic organization identification and optimization ways area unit developed to make key points.Regional control optimization ways and style,establish an expert work framework for urban light services,and propose optimum solutions for traffic organization and signal temporal arrangement optimization;finally,the traffic simulation software system VISSIM is employed for simulation verification to verify the practicalness and effectiveness of the simulation,and also the results it shows that the optimization of light management will effectively cut back the typical delay and also the range of stops of the traffic flow,and also the traffic potency of the traffic flow has been considerably improved.Regarding a single intersection as the smallest unit of signal control,and the coordinated control of arterial and regional signals as the optimal signal control scheme,it is of great significance and practical research value to improve the capacity of urban roads,improve the efficiency of road networks,and alleviate urban traffic congestion.Wishing on the technological and intelligent means that of traffic management,this text builds a symbol management application atmosphere with comprehensive perception,active analysis,and precise management,realizes comprehensive transportation management and sensible transportation prospective application demonstration,comprehensively improves transportation capability and comprehensive service level,and builds a progressive international The pattern of transportation development with coordinated urban functions.
