基于VISSIM模拟的“运行车速断面图”

“Driving Speed Section Profile” Based on VISSM Simulation

运行车速断面图能较好地对道路的线形进行评价,从而分析交故事故的潜在原因。目前计算运行车速会耗大量的人力、物力和财力。运用软件VISSIM模拟道路运行车速的方法,对于已建道路的线形安全分析能节省很大财力;对于正在设计的道路线形也有很好的预测和分析作用。

Road line type can be evaluated well with ＂driving speed section profile＂,and the hidden reason of traffic accident can be analyzed.At present,the calculation of driving speed consumes a number of manpower,financial expenditure and material resource,but it can save financial expenditure by VISSIM software to analyze existed road line.The software can also predict and analyze road line type which is under designing.
