| 摘 要： | 以机动车尾气扩散模型为核心,采用集成微观交通仿真平台PARAMICS和地理信息系统建立城市道路交通环境模拟系统(UTESS)的方法,将交通仿真技术与GIS技术应用到机动车尾气污染扩散模拟中。以广州市为例,给出了该系统的验证过程与应用实例。文章通过模拟道路下风侧接受点逐时的CO与NOX浓度进行验证,模拟值与实测值的平均相对误差分别为25.1%和15.6%;应用实例采用UTESS模拟路网上空10m高度的CO浓度分布,模拟结果较好的反映了不同路段交通流对CO浓度空间分布的影响。

| Abstract: | Simulation system of urban road traffic pollution-UTESS which based on a vehicle emission dispersion model that integrated with microscopic traffic simulation system-PARAMICS and geographic information system(GIS)was established to simulate air pollution induced by vehicles exhaust.Taking Guangzhou for instance,hourly concentrations of COD and NOX on leeward side of street were simulated,with average relative errors of analog values compared with measured values of 25.1% and 15.6% respectively.UTESS was use... |
