Research On Traffic Flow Equilibrium Strategy In Time And Space

At present, the problems of urban traffic congestion are getting more and more serious. The generation of traffic congestion is a product of interaction of multiple factors. Different angles should be considered to solve the problems of traffic congestion, and not only the short-time interests and efficiency should be considered, but also the sustainable development strategic should be embodied fully.Zibo is one of a few cities with typical group character in our country. All urban areas are centralized relatively and present the "Cross" structure, but, the whole city shows a phenomenon that is centralized and not aggregation. Taking ZiBo city as an example, space-time balancing strategies are used to study the transport development strategy based on the analysis of "group" character and the transportation. Some aspects are included as follows:Firstly, trip characteristics are analyzed based on survey data.Secondly, typical problems of urban traffic are analyzed, and the solution countermeasures are proposed from the angles of green transportation and equilibrium in time and space;Thirdly, optimization of the road system of ZiBo city, traffic organization development strategy of Gaoqing, the tactic of variable message signs, parking guidance and the tactic of one-way traffic are studied from macroscopic, middlescopic and microscopic based on the situation of ZiBo city. And the traffic simulation software VISSIM is used to evaluate some programs;Finally, the paper is summarized and looked into the future.
