一种恶劣天气下高速公路车流稳健控制方式

A moderate expressway vehicle flow control under atrocious weather condition

高速公路的安全运营受恶劣天气影响显著,尤其是在极端恶劣的天气情况下。在车辆跟驰理论的基础上提出了一种车流控制方式,并结合车间距和车流安全的影响因素,推导得出了恶劣天气下能见度与高速公路安全行车速度的关系。研究为恶劣天气条件下高速公路的不间断安全运营提供了理论依据。

The safety of expressway operations dues to atrocious weather significantly,particularly in the extreme atrocious weather conditions.This article brings forward a vehicle flow control mode on the basis of the car following theory,combining traffic safety with the safe interval distance establishes the relationship between visibility and the expressway safety speed.The application of the achievement in this paper provides a way to strengthen the expressway safety and non-stop operation under the atrocious we...
