This paper presents a newly developed microsimulation model for motorway roadwork sections to evaluate the efficiency of different temporary traffic management schemes (TTMSs) such as the use of narrow lanes, offside and inside lane closures. The effect on traffic performance of various parameters (e.g. flow rates, percentage of heavy goods vehicles (HGVs), roadwork zone lengths and speed limits) has been tested. The model was built using the FORTRAN programing language. It was developed based on car-following, discretionary lane changing, mandatory lane changing, gap acceptance and narrow lanes rules. Data from four sources (including data taken from different UK motorway sites) were collected and analyzed. The data were used in the verification, calibration and validation processes of the model. Observations from motorway roadwork sites with the narrow lanes scheme show certain prominent drivers’ behaviors, namely avoiding passing HGVs traveling on adjacent lanes and lane repositioning before passing a HGV. Such behaviors were included in the modeling process which suggested that the presence of HGVs had a noticeable impact on reducing section capacity.

窄车道高速公路道路工程微观仿真模型的开发

本文提出了一种新开发的高速公路道路施工段微观仿真模型，以评估不同临时交通管理方案 (TTMS) 的效率，例如窄车道的使用、越位和内侧车道封闭。已经测试了各种参数（例如流量、重型货车 (HGV) 的百分比、道路施工区长度和速度限制）对交通性能的影响。该模型是使用 FORTRAN 编程语言构建的。它是基于跟车、自主变道、强制变道、间隙接受和狭窄车道规则而开发的。收集并分析了来自四个来源的数据（包括来自不同英国高速公路站点的数据）。这些数据用于模型的验证、校准和验证过程。对采用窄车道方案的高速公路道路施工现场的观察显示了某些突出的驾驶员行为，即避免超车在相邻车道上行驶的重型货车和在超车前重新定位车道。这种行为被包含在建模过程中，这表明 HGV 的存在对降低部分容量有显着影响。
