寒冷地区二级公路路段交通微观仿真研究

Research on the traffic simulation of second class highway in cold area

以通行能力研究为主要目的 ,在调查掌握寒冷地区二级公路交通流特性的基础上 ,借鉴国内外成熟的交通流仿真模型 ,建立了以发车模型、自由行驶模型、跟驰模型和超车模型为主要模块的寒冷地区二级公路路段交通仿真模型 ,并对各子模型进行了详细的描述 ,最后给出寒冷地区二级公路的路段通行能力及车辆换算系数。

The paper establishes the traffic simulation model which includes generation model,free travelling model,car following model and overtaking model.The simulation model integrates the concept of some advanced models in traffic simulation.The traffic flow characteristics of second class highway in cold area are considered as well.The sub models are described at full length in the paper.At last,the capacity and PCE of second class highway in cold area are suggested.
