摘要
交通堵塞成为城市发展的障碍,对交通系统的性能影响较大。路网结构是城市交通系统性能的一个重要影响因素。为缓解城市交通拥堵,研究矩形城市交通路网结构对城市交通系统性能的影响具有重要意义。保持矩形交通路网的总面积不变,改变矩形交通路网的长宽比,在具有时变加载过程的开边界条件下,模拟了地理最短路径选择策略(GSP)和时间最短路径选择策略(TSP)情况下的交通系统性能。模拟结果显示正方形交通路网具有较好的性能。
Traffic congestion has become an obstacle for urban development,which has a great impact on the performance of traffic system.The road network structure is an important influencing factor of the urban traffic system,the impacts of rectangular urban traffic road network structure on the performance of traffic system is studied.Keep the total area of rectangular road networks and change the length-width ratio of rectangular urban traffic road network structure.Under the open boundary condition with time-varying loading process,the traffic system performance with both geographic shortest path routing strategy(GSP)and time shortest path routing strategy(TSP)is simulated for the different length-width ratio.The simulation results show that the square road network has better performance.
