Arterial Coordination Control Partition Criteria For Dedicated Bus Priority

With the economy growing,construction of urban public transport service is becoming the top priority of the urban road traffic development.Thanks to the bus signal priority arterial cooperative could achieve easy implementation and remarkable results that can enhance the level of urban public transport services.The further research about arterial priority control methods will be of great practical value once the bus transit lane is continually promoted.this review focuses on bus dwell time prediction,the control work zone partition for bus signal priority arterial cooperative,and the coordination control of bus signal priority arterial cooperative.Mainly including the following three parts:Firstly,make use of the data preprocessing technology to get core data matrix consists of bus arrival time and dwell time,Using regression analysis to work out the best relevance regression function between bus arrival time and bus dwell time,and then we get the prediction bus dwell time by function analysis.At last,with dynamic optimization strategies to optimize the forecast results in real time condition;Secondly,based on the prediction bus dwell time,the average speed of the arri-station and the average speed of the off-station,we calculate the time when the bus arrives at the downstream intersection through the detector to obtain the bus arrival time;Combined with downstream intersection signal control scheme we get the probability of bus through the intersection without stopping,and then divide the control work zone partition for bus signal priority arterial cooperative by probability.At lasr,verify the results by simulation;Thirdly,this review determine the weighted proportion between bus and social vehicle by using spectral clustering(SC)method.And then design multi-period division program for intersection by using Piecewise Aggregate Approximation(PAA).Finally design scheme of bus signal priority arterial cooperative under multi-period condition.
