Research On Traffic Organization Optimization Of Urban Expressway

In the process of urban expressway construction,traffic organization is a major problem in construction.The construction of urban expressway will inevitably be carried out on the existing roads.The road occupation construction will inevitably reduce the traffic capacity of the existing roads,interfere with the normal traffic order,and bring more severe challenges to the already congested urban traffic.In view of this phenomenon,it is of great guiding significance for the construction of urban expressway to carry out traffic investigation and prepare reasonable traffic organization scheme.At the same time,the means of traffic demand prediction can balance the contradiction between supply and demand brought by traffic development,avoid the phenomenon of congestion when roads are completed,and then reasonably predict the construction significance of urban expressway.Finally,by means of traffic evaluation,systematically analyze the impact of urban road construction,study and formulate scientific and reasonable traffic organization scheme,and optimize the traffic organization scheme according to the project implementation,which has important practical significance to alleviate the traffic pressure caused by urban expressway construction.Starting from the research status at home and abroad,this paper studies and analyzes several important influencing factors,principles and traffic impact on urban expressway construction.Traffic demand forecasting uses the traffic planning software Trans CAD and the traditional "four stage" model.Its traffic prediction model uses a mathematical model to simulate the characteristics of travel,that is,travel occurrence,travel distribution,traffic mode division and traffic allocation.The optimization of traffic organization scheme is studied and analyzed from the macro and micro perspectives to judge that different optimization methods are suitable for different construction situations.On the basis of theoretical research,this paper first puts forward the traffic organization scheme of the municipal project of the South extension of Ruyi road to the East transit channel,including construction and surrounding traffic development,traffic investigation and construction methods,and then forecasts the traffic demand of the municipal project of the South extension of Ruyi road to the East transit channel,Analyze the importance and significance of project construction.Finally,the traffic organization scheme is optimized and analyzed,and the scheme effect is evaluated.According to the actual construction of the project,the optimization of the traffic organization scheme has achieved good construction results.The traffic organization optimization analysis idea proposed in this paper provides a good reference value for the preparation of traffic organization scheme for urban expressway construction in China.
