一、测定车速的意义速度是交通运行情况的基本量度。为了探求公路发展的趋势,制定国家公路工程技术标准,分析公路经济效益与线形几何设计是否合理,估计道路交通阻塞程度,检验公路养护管理优劣及交通控制效果,事故分析,评价道路服务质量及通行能力,在城市里作交通规划等。为此,应尽快、准确、方便的寻求出车速测定方法。本文提出用 PC-1500计算机直接采集原始数据,进行处理分析并输出结果,获
First, determine the meaning of speed Speed is the basic measure of traffic conditions. In order to explore the trend of highway development, formulate national highway engineering technical standards, analyze the reasonableness of highway economic benefits and linear geometric design, estimate the degree of road traffic congestion, test the pros and cons of highway maintenance management and traffic control effects, analyze accidents, evaluate the service quality of roads and Capacity, traffic planning in the city. To this end, as soon as possible, accurate and convenient to find a speed measurement method. This paper proposes to use PC-1500 computer to directly collect the raw data, analyze and output the results
