针对我国高速公路安全事故多、运输效率偏低、运营成本高的问题,基于国内高速公路交通安全及交通效率的现状,探究了我国现阶段高速公路在交通运行特点、交通安全状况、交通效率特征下的限速体系。从高速公路线形、车辆、环境、管理和驾驶者等方面分析了影响车速的因素,提出了在高效、快捷、顺畅条件下实施科学的限速体系是保障高速公路安全水平和运输效率的主要措施。
Aiming at the problems of many highway accidents, low transport efficiency and high operation cost in our country, this paper explores the characteristics of traffic operation, traffic safety and traffic efficiency in our country at the present stage based on the current situation of traffic safety and traffic efficiency of expressways in our country. Under the speed limit system. The paper analyzes the factors that affect vehicle speed from the aspects of expressway shape, vehicle, environment, management and driver, and puts forward that implementing a scientific speed-limiting system under high efficiency, speed and smoothness is the main measure to ensure the safety level and transportation efficiency of expressway .
