信控交叉口交通参数与评价指标综合观测法

在研究分析信控延误与饱和流量的常用观测分析方法的基础上，提出了信控交叉口评价指标、设计参数综合观测、统计、分析的新方法。新方法采用摄（录）像或人工现场观测与计算机软件统计分析的方法，不仅能获得信控延误、停车次数、停车率、停车平均延误等与延误相关的信控交叉口评价指标的实测数据，还能获得车头时距、饱和流量、起动损失时间、交通量等信控交叉口设计与配时所需的交通参数，故简称为“综合”法。

A New Method of Saturation Flow and Signal Control Delay Survey

In this paper, a new method of saturation flow and signal control delay survey is presented, base on the analysis of saturation flow, signal control delay and their traditional survey method. The new method adopts video record survey or field investigation and integrates with software technique for analyzing survey data. Many performance index related with delay, signal control delay, the number of stopped vehicle, the rate of stopped vehicle, average delay of stopped vehicle and many design parameters of signalized intersection can be obtained at one time through this new method named Integration method.
