该模型方程反映了以下特性: • 模拟更新时间步长等于反应时间∆t。 • 如果当前速度大于vsafe - a∆t或v0 - a∆t,则车辆将在下一个时间步骤中达到v0和vsafe的最小值之一。(严格来说,这意味着减速(v - vsafe)/∆t并不限于b。在多车道模拟中,如果另一辆车在被考虑的车辆前面“插入”,它可...

跟车模型是交通流仿真中采用的一个基本模型 。 3. Aimed to solve the deficiency of neglecting the different performances among various individual vehicles,which exists in the present car following models used for traffic simulation,this paper puts forward a pure-micro car following model. 针对目前在...
该模型的基本思路是:一旦后车驾驶员认为他与前车之间的距离小于其心理(安全)距离时,后车驾驶员开始减速。由于后车驾驶员无法准确判断前车车速,后车车速会在一段时间内低于前车车速,直到前后车间的距离达到另一个心理(安全)距离时,后车驾驶员开始缓慢地加速,由此周而复始,形成一个加速、减速的...
