摘要
详细设计城市路网可靠性动态交通仿真及评价系统,阐述各组成模块的功能和作用及相互关系。在采集实时交通数据的基础上,以PARAMICS为基础,利用其OD估计模块Estimator,推导城市路网全天的动态交通需求,针对微观交通仿真输出结果的特点,选择90%分位行程时间和行程时间波动性两个指标建立行程时间特性评价模块,并设计其功能界面,利用PARAMICS的二次开发功能,将行程时间评价植入其仿真模块(Modeller),实现仿真、评价的一体化和自动化。最后通过昆明市学府路、一二一大街片区路网验证系统的可行性。
A dynamic traffic simulation and evaluation system of urban road network reliability was designed in detail, and the module functions and roles and relationships between the modules were expounded. On the basis of collecting real-time traffic data, the road network dynamic traffic demand throughout the day was deduced based on the OD estimation module Estimator of PARAMICS. Considering the characteristics of the microscopic traffic simulation output, travel time characteristic evaluation module was built through selecting two indicators of the 90% sub-bit travel time and travel time fluctuation, and then its function interface was designed. Then travel time evaluation was implanted to the simulation module （Modeller） by using the secondary development function of PARAMICS, to achieve integration and automation of simulation and evaluation. Finally, the feasibility of the system was verified by an instance of Xuefu and 121 street area network of Kunming.
