摘　　要：驶入高速公路的车辆从匝道进入加速车道后,将尽快选择时机汇入主线,换道行为难免会对后随车造成干扰,破坏主线交通流稳定性。随着车联网技术的发展,为上匝道车辆设置统一的车道选择决策算法成为可能,目前鲜有模型能够从减小对主线系统车流影响的角度研究上匝道车辆的车道选择行为。该模型基于车联网环境分析了高速公路入口交织区的车道选择决策过程,用能耗值量化上匝道车辆造成的交通干扰,并以最小化主线系统能耗为目标建立了上匝道车辆车道分配模型。研究结果表明:模型能够从系统能耗最优的角度输出上匝道车辆的车道分配方案。After entering the acceleration lane from the ramp,vehicles that want to enter the expressway will choose the opportunity to join the main line as soon as possible,the lane-changing behavior will inevitably cause interference to the following vehicles and damage the stability of the main traffic flow.With the development of vehicle networking technology,it is possible to set up a unified lane selection decision algorithm for on-ramp vehicles.At present,few models can study the lane selection behavior of on-ramp vehicles from the perspective of reducing the impact on the traffic flow of the main line system.This model analyzes the lane selection decision-making process of the expressway entrance weaving area based on the vehicle networking environment,quantifies the traffic interference caused by the on-ramp vehicles with the energy consumption value,and establishes the lane allocation model of the on-ramp vehicles with the goal of minimizing the energy consumption of the main line system.The research results show that the model can output the lane allocation scheme of on-ramp vehicles from the perspective of optimal system energy consumption.
