【摘要】 二维交通仿真的输出界面粗糙,对城市环境及各种交通状况的描述也只能做到几何形态上的粗略表达,而三维仿真能够克服这些缺点,制作出精细的城市交通模型。为此使用韦伯斯特(Webster)算法得出1个交叉路口交通信号灯的配时方案,然后使用三维动画软件3DS MAX对交叉路口进行建模和交通控制信号灯的仿真,汽车运行的仿真应用3DS MAX内置的脚本语言MaxScript实现。通过仿真,可以看出三维仿真比二维仿真更加直观,而动画效果,使路网中的交通问题更加显而易见。更多还原

【Abstract】 The output interface of 2D simulation on traffic is very coarse.2D simulation on traffic can only display the city and the traffic with simple geometric objects.3D simulation can overcome these shortcomings,and it can make an elaborate model for urban traffic.This paper calculates the time for traffic signals of a multiphase single intersection with Webster algorithm.Then a model for the single in- tersection is created and simulation for the signals is set with 3DS MAX.At last the simulation for the cars on the traffic going through the intersection is realized with MaxScript built in 3DS MAX.3D simu- lation on traffic is more conspicuous than 3D simulation,and the animation makes the problems in the traffic obvious.更多还原
