在加速车道行驶时,要增加车速至同高速上车辆相适合。
The length design of the acceleration lane depends on not only traffic speed but also traffic volume of the main line and ramp of expressway interchanges.高速公路加速车道的设置长度不仅取决于主路及匝道的设计速度,还与主路及匝道的交通量有关。
Considering the vehicles' changeable critical headway when driving along the acceleration lane of an on-ramp, a vehicle merging model was proposed using differential method.考虑驾驶员在入口匝道加速车道上行驶过程中车辆汇入的临界间隙变化的情况,应用微分法推导求得加速车道上车辆的汇入概率模型。
