摘要:

临近交叉口的车辆往往呈现出复杂多样的跟驰换道行为.基于二维最优速度 (OV)交通流模型,本文构建了一个改进的双车道车辆跟驰换道模型,以刻画交叉口前路段上的车辆跟驰换道机制及车流宏观特征.借助模型分析了换道车辆比例、换道期望参数和跟驰安全距离等对交通流宏观特征的影响.结果表明:换道车辆比例对通过停车线的进口道流量有负面影响,换道行为越多,进口道流量越小.换道期望参数越大,换道成功率越大;当道路拥堵时,增大换道期望会减少进口道流量.增大安全距离,容易提升换道成功率但会减小进口道流量,同时促使拥堵发生.

Abstract:

Car- following and lane-changing behaviors near an intersection exhibit the diversity and complexity of features. This paper proposes an modified two lane car- following and lane- changing model based on a two-dimensional optimal velocity (OV) model to explore the interaction mechanism between carfollowing and lane-changing and macroscopic traffic flow characteristics in front of the intersection. Using the model, the impact of different percentages of lane-changing vehicles, safety distances and desired parameters of lane-changing on traffic characteristics are investigated. The results show that the lanechanging behavior near the intersection has negative impacts on traffic flow. The traffic state becomes more seriously with larger percentages of lane-changing vehicles. The lane-changing success rate becomes larger as the increase of desired lane-changing parameter. The increase of desired lane-changing parameter leads to decrease of flux, when traffic congestion appears. The larger safety distance is easier to cause traffic congestion, because of the decrease of flux, while the success rate of lane-changing is improved.
