双向两车道交通流模型的车辆转道规则研究

Study on Lane Changing Rules of Two-lane Bidirectional Traffic Flow Model

在对已有双向两车道模型的车辆转道规则研究的基础上,考虑驾驶员转道特性,提出均一车辆双向交通流模型两种新的车辆转道规则,并绘制了新车辆转道规则的交通流基本图.模拟结果表明,当逆行道初始密度较小时,与单车道模型相比,两种新规则均能够提高母车道的车辆通行能力,且通过选择合适的模型参数,模拟误差率<5‰,与实测数据近似.

Based on the existing lane changing rules for two-lane bidirectional traffic flow model,two new rules were proposed by taking into account the driver＇s turning characteristics. The fundamental diagrams of traffic flow under these new rules were obtained. Simulation results showed that compared with the sin- gle-lane model, the models with two new lane changing rules could enlarge the home lane traffic flow when the density on the opposite lane was small. By choosing the appropriate model parameters, the simulation results were similar to the experimental data with an error rate less than 5 per thousand.
