摘要
城市道路阻抗模型是交通分析软件系统的重要组成部分,其合理与否直接关系到预测结果的科学性。针对我国城市道路混合交通流的特点,结合深圳市城市道路交通流调查和交叉口延误调查结果,建立行程时间的分段模型,可使交通预测的结果更加科学合理。
The link travel time function for urban road is one of important parts of the software of the traffic analysis. Its rationality directly associates with the science the forecast results. Based on the charac- teristic of the mixed traffic flow in China city, the partial model of the travel time was put forward combining the survey results of the traffic road flow and the intersection in Shenzhen, which makes the forecast results more scientific and rational.
