中观仿真模型以车辆群体为分析单元，与宏观模型相比具有分析精度高、分析指标全面等特点，与微观模型相比具有建模工作量小、运行速度快、路径分析功能强等优点，是进行区域交通分析最适合的工具。以中观仿真模型TransModeler为研究对象，从路段和交叉口两个层面说明模型的车队分离和合并原则，从车队的头车和尾车的速度模型分析车队的整体运行模式以及区域交通的工作流程，详细说明可以参照宏观模型划分区域小区，利用路段流量反推OD矩阵、模型校核流程及区域仿真评价指标等。该研究为中观仿真模型的研究提供理论借鉴，并为利用TransModeler从中观层面分析区域交通奠定基础。

Mesoscopic traffic simulation model take traffic cell as analysis unit ,each traffic cell consists of a list of vehicles that move together according to the same traffic dynamics .Compared with the macro model , meso model has many characteristics such as high accuracy in analysis , analysis indicators comprehensive etc .Moreover ,it also has some advantages compared with micro model ,such as less modeling workload ,faster program running speed ,stronger path analysis function etc .So that it could be a best choice to do the regional analysis . This paper takes TransModeler software as research object , introduce the principles of traffic cells in merging and splitting situation and the operational mode of traffic streams based on the speed model of the “head” and “tail” vehicles . Further descript the w orkflow of regional transportation analysis based on meso‐model ,such as the division of traffic zones with reference to the macro model , inverse deduction of O‐D matrix based on the link flow s , the process of model verification and regional simulation evaluation index etc .Overall this paper provides a theoretical reference to mesoscopic traffic simulation model research and lay a foundation of regional analysis from meso level based on TransModeler software .
