| Along with the increasing development of social economy and urbanization, the urban traffic problem has been put outstanding. Urban arterial road is the main undertaker of the urban transportion.Theerfore, the study on the traffic organization and optimization should be the major course in solving and improving the urban traffic problem.The dissertation catches the urban arterial road as studying object, makes some researches on the urban main road traffic organization and optimization from two aspects: traffic channelization and traffic signal coordinated control. Firstly, the paper makes a deeply analyses on the traffic organization in main road segment, including the linking section of intersection and road segment, the roadway, passing-street for pedestrian, public transportation and road speed. Then, the optimized route guidance procedure for segment traffic is offered.As the node of city road net, intersection would be a bottleneck if its traffic flow not be put in order. Analyzing the traffic characteristics of intersection especially the channelization of signalized intersection, the thesis gives the control idea that collision can be decreased and the capability and security can be improved by combining space with time intersection. The design of multiphase channelization control based on the Guangming-Heping intersection in Handan city is delivered in this thesis.In the end, the dissertation summarizes the findings and achievements, and puts forward the issues, urban traffic organization and optimization,for further research direction. |
