The traffic congestion in ramp areas is becoming increasingly prominent. In the upstream segments of ramp areas, effective management and control of lane-changing behaviors can improve the road capacity and make full use of the existing road resource. With the continuous development and application of connected vehicle technologies, lane-changing behaviors can be performed by vehicle groups. Under a connected vehicle environment, the lane-changing behaviors by vehicle groups are controlled in the upstream segment in a ramp area, and the lane-changing behaviors can be completed prior to entering the ramp area. Finally, lane-changing strategies are optimized and identified. VISSIM simulates these proposed strategies. This paper considers the delay as the output index for analyzing and comparing various strategies. The results demonstrate that the delays of different lane-changing strategies are also different. If the delays of ramp areas are to be substantially reduced, it is necessary to continuously optimize the lane-changing strategies by vehicle groups in the upstream segments. This optimization of lane-changing strategies will effectively regulate drivers’ lane-changing behaviors, improve road safety, and increase traffic capacity.

基于VISSIM的匝道区域上游路段的仿真和分析，以优化车辆组换道行为

坡道地区的交通拥堵日益突出。在坡道上游段，有效管理和控制变道行为可以提高道路通行能力并充分利用现有道路资源。随着互联车辆技术的不断发展和应用，车辆组可以执行变道行为。在连接的车辆环境下，可以在坡道区域的上游段中控制车辆组的变道行为，并且可以在进入斜坡区域之前完成变道行为。最后，对换道策略进行了优化和识别。VISSIM模拟这些建议的策略。本文将延迟作为分析和比较各种策略的输出指标。结果表明，不同换道策略的延误也有所不同。如果要大幅度减少坡道区域的延误，则必须通过上游路段的车辆组不断优化换道策略。换道策略的这种优化将有效地调节驾驶员的换道行为，提高道路安全性，并增加交通容量。
