Analysis And Design Of Urban Traffic Microscopic Simulation System Core Module

With the further development of cities, the urban traffic congestion has become severe problems of countries all over the world especially the developed countries. For the purpose of solving the urban traffic problems, countries all over the world put huge efforts in infrastructure and traffic management, at the same time all the organizations of scientific research actively make good use of all kinds of advanced technological productions to provide ways of improving traffic conditions. Traffic microscopic simulation technologies provide effective ways of solving these problems. Through traffic simulation, can carry through reasonable evaluation and make up the corresponding measures to realize the purposes of improving traffic conditions and save costs given the premise of not changing the current traffic infrastructures. This paper starts with the analysis of the road network model and vehicle model in the traffic microscopic simulation system, and puts up the methods of solving traffic problems using the object-oriented ideology thought combined with computer software technology through the software realization of the road network framework and basic functions of vehicles in the core subsystem of traffic microscopic simulation system.This paper firstly introduces the development situation of domestic and foreign traffic microscopic simulation system, secondly analyzes the structures and models of traffic microscopic simulation system in detail, then discusses the analysis and design of the core subsystem of traffic microscopic simulation system at emphasis, and carries through the primary validation of road network framework and basic functions of vehicles by means of designing a simulation case alone.Main work:(1) On the basis of control of the total structure of traffic microscopic simulation, put great emphasis on the requirements analysis and design thought of core subsystem.(2) Carry through the further optimization and improvement using linklist structure aiming at the relevant classes and functions of the road network module and vehicle module in the core subsystem of traffic microscopic simulation system, demonstrate the object-oriented thought well.(3) On the basis of deeply understand of structure and function of vehicle module, make further analysis and research on how to save and transfer the vehicles' dynamic information in time using ADO technology accessing simulation traffic dynamic...
