The Convergence Model Of Viaduct Expressway Exit Ramp And Conventional Road With Simulation Research

In this thesis, on the basis of a comprehensive and systematic analysis betweenurban elevated expressway and conventional road system in convergence system andflow characteristics.Analysis Expressway exit ramp of macro-and micro-location,theproposed exit ramp is the study of expressway and conventional road of the priorities ofconvergence problem.Taking into account the impact of driving ramp traffic and theground road traffic caused by interleaving,Established emplaced location model basedon transfer matrix theory elevated freeway exit ramp,on this basis, proposed some viewsof the Expressway and conventional roads converge at the ground position.Insimulation research,through the simulation evaluation of the convergence area andsubstituted into the traffic data collected samples of the proposed model,timulationverified by comparing the results obtained with the actual situation emplaced validity ofthe model can improve the efficiency of vehicle traffic.Expressway exit rampconvergence at the traffic conditions optimized and Expressway construction planningand construction to provide some reference.
