SOA下的城市道路交通网络极限容量判定模型

Decision Model of Urban Road Traffic Network Limit Capacity Based on SOA

基于出行者出行行为,研究基于面向服务架构(Service-Oriented Architecture,SOA)的城市道路交通网络极限容量判定模型。考虑路段通行能力等约束条件下的极限流量问题,基于信息共享平台获取交通信息,应用美国联邦公路局(Bureau of Public Road,BPR)函数与启发式算法,获取极限容量判定结果。实验结果显示,基于判定结果调整道路交通网络结构后,可实现城市道路交通网络供需平衡。

Based on the travel behavior of travelers,a model for determining the ultimate capacity of urban road traffic networks based on Service-Oriented Architecture(SOA)is studied.Considering the limit flow problem under constraints such as road capacity,traffic information is obtained based on an information sharing platform,and the Bureau of Public Road(BPR)function and heuristic algorithm are applied to obtain the result of determining the limit capacity.The experimental results show that adjusting the road traffic network structure based on the judgment results can achieve a balance between supply and demand in urban road traffic networks.
