干线公路期望车速确定方法分析

Main Highway Expectation Vehicle Speed Definite Method Research

调查小客车和大货车在甘肃省4条国道干线公路上的运行车速情况,并根据期望车速的概念,对期望车速影响因素进行分析,同时对4条干线公路上典型路段的车速测量数据进行研究,提出干线公路期望车速确定方法,并结合甘肃省干线公路的实际车速测量数据,对期望车速模型进行验证。

Investigate the small passenger vehicles and large goods vehicles at the four State Road in Gansu province on the main highway running speed, and speed in accordance with the concept of expectations, expectations of the speed of the influencing factors were analyzed simultaneously on the four main highway on a typical road sections, their speed measurement data conducted a study on the expectations raised high- way speed to determine methods and combination of arterial highways in Gansu Province actual speed measurement data, the expectations of the speed model of the actual authentication.
