two-lane traffic造句

• Second , we introduce a two - lane traffic model which is based on the ( 0 , 2 ) and ( 0 , 1 , 2 ) models . we mainly study the coupling effect of lanes . in two - lane traffic , vehicles can change lanes and overpass . the interactin between lanes is considered as coupling effect . the computer simulation indicate that ( dthe current of the system with cupling is greater than that without coupling ; 0for a certain initial density , the average flow and speed are indepent on the coupling coefficient which is greater than zero ; when the initial densities ( speeds ) of lanes are different , the characters of traffic system will be different
  在单车道模型的基础上，建立v _ ( max ) = 2双车道模型，研究车道的耦合效应。双车道模型中车辆可以进行转道、超车，两道之间有耦合作用。模拟结果说明，有耦合时系统的流量比没有耦合时大；在固定的初密度条件下，只要耦合系数b 0 ，两道间的耦合强弱对流量和速度无影响；两道初密度分布不均匀和速度分布不均匀都能使交通系统特性发生变化。
