The intersection with special width approach lane (SWAL) is a newly proposed unconventional intersection design. A microscopic traffic flow model was proposed for describing the operation of vehicles at signalised intersections with SWAL. The operation process of driving on the SWAL was divided into four segments, including entering segment, transition segment, special width lane segment, and exiting segment. The car-following and lane selection behaviours of vehicles in these segments are analysed. The parameters used in the model were calibrated using the field data collected in Germany. The proposed model was realised in a time-discretised simulation. The sensitivity analyses of geometric, traffic, and signal factors were conducted. The results show that for the car-following behaviour, the passenger cars on the narrowed lanes cannot drive as efficient as on the normal width lane. For lane selection behaviour, it mainly depends on the distance between the two nearest vehicles in front of the two narrow lanes. The effectiveness of the SWAL depends on whether it is long enough to accommodate the queuing vehicles, which is a combined result of the layout design and the signal timing.

根据现场数据对具有特殊宽度进近车道的信号交叉口的车辆运行进行建模

具有特殊宽度进近车道的交叉口（SWAL）是新提出的非常规交叉口设计。提出了微观交通流模型，用于描述在带有SWAL的信号交叉口处车辆的操作。SWAL上的驾驶操作过程分为四个部分，包括进入部分，过渡部分，特殊宽度车道部分和出口部分。分析了这些路段中车辆的跟车行为和车道选择行为。使用在德国收集的现场数据对模型中使用的参数进行了校准。所提出的模型是在时间离散的仿真中实现的。进行了几何，交通和信号因素的敏感性分析。结果表明，对于跟车行为，狭窄车道上的乘用车不能像正常宽度车道上那样高效地行驶。对于车道选择行为，主要取决于两个狭窄车道前面的两个最近车辆之间的距离。SWAL的有效性取决于是否足够长以容纳排队的车辆，这是布局设计和信号时序的综合结果。
