摘要
把NaSch模型的刹车概率分开为独立的加速和减速概率,引入转道规则,建立了双车道多速车辆的混合交通流模型.通过计算机数值模拟,得出了不同参数下混合交通的速度和流量与密度关系的基本图.结果表明,转道概率、混合比例和加减速概率对混合交通都有重要的影响,慢车的特性对混合交通起着决定性的作用.
Based on the Nagel-Schrekenberg(NS) model,we present a mixing traffic flow model for a two-lane traffic system. In this model, the stochastic noise P in NS model is replaced by accelerating probability P-a and braking probability P-d. The fundamental diagrams of the mixing traffic under different conditions are given by the numerical simulations. We found that the lane-changing probability,the mixing rate and acceleration, the braking probability have a great influence on the mixing traffic flow. The slow cars have a decisive action on the mixing traffic.
