Analysis Of Conflict And Traffic Organization Optimization At Signalized Intersections With Channelized Right Turn Lanes

With the widespread use of channelized right turn lane,some traffic conflict has changed but there is a mountain of study work need to do.The thesis relies on national nature science found of China(Project Name: Research on mixed-traffic flow operational mechanism at intersection based on total time and space information.Project Number: 51278220).On the basis of learning of previous studies,this dissertation explored two typical conflicts at channelized right turn signalized intersection and proposed some systematical and efficient methods.Full text contains five chapters.The first chapter is an introduction about research background,research significance,research contents and innovation points.The second chapter introduced the main method we used.This chapter also discussed the application of this method on traffic domain and the feasibility on this article.This chapter aims to get better awareness of the conflict between channelized right turn vehicles and pedestrians at signalised intersections.After the conflict risk analysis of pedestrians who wanted to cross the road,what can be concluded is that pedestrians' yielding behavior to vehicles and the occurrences of vehicle-pedestrian conflict are influenced by the speed of pedestrians,the scale of groups,the trajectory chose by pedestrians to cross the intersections and the direction whether the pedestrians are entering or exiting the intersection.The third chapter probed into the influence of channelization approach to conflicts between vehicles and vehicles at channelized right turn lane exit and classified channelization approach by conflict forms.This chapter also analyzed the enforcement effect of channelization line in Changchun by before and after comparison as well as put forward corresponding improvement measure.The forth chapter proposed the objectives and principles of organization optimization as well as some improvement measures.All the proposals are based on observation and study results on preceding chapters.The fifth chapter is the summary and outlook for the study.This part summarized present work product and deficiency,in the meantime,it illuminated further study orientation.
