two-lane roadway meaning in English

双车道道路

In the third chapter , an improved ca model of the traffic flow in the two - lane roadway is proposed to describe highway traffic under the open boundary conditions by the consideration of the relative motion of vehicles and the relation of deceleration probability . numerical simulations have been carried out
本文先在改进的ns元胞自动机交通流模型的基础上，提出一个高速公路双车道元胞自动机模型来模拟开放性边界条件下的车流运动，并考虑两车道之间左边界开放程度的比例系数及车辆加减速概率影响。
First , the recent studies of ca models for traffic flow , based on the statistical physics , are introduced in the thesis . at the same time , all kinds of models based on the determined ca are also introduced in detail . second , we introduce the improved ns model presented by xueyu to the ca traffic flow model of a two - lane roadway in a highway and on a urban main road
本文首先综述了各种交通流模型，在简单介绍了元胞自动机及其理论的基础上，重点介绍了元胞自动机交通流模型，并在此基础上，对薛郁提出改进的ns模型加以应用和推广到双车道高速公路交通流模型和城市主干道交通流模型中。
