货车交通对高速公路安全性的影响

Influence of Heavy Vehicles on Traffic Safety of Freeways

根据国内某典型重载高速公路近几年交通事故的统计,在现场调研和车速观测的基础上,充分考虑汽车行驶理论、道路环境和驾驶员特征,就载重货车交通对高速公路运营安全性的影响进行了研究.研究结果表明,事故的发生与车辆的实际操纵性能有关,超载、不同车型之间运行车速的显著差异、行车注意力不集中及纵向间距不足等是造成货车交通事故的主要原因.从工程、交通管理等角度对提高高速公路运营安全水平提出了相应的改进措施.

In terms of traffic accident statistics in recent years sampled from a typical heavy transportation freeway in China and based on the field survey of vehicle operating speed on highway sections,the influence of heavy vehicles on freeway safety with regard to vehicle running theory,freeway environment and drivers' characteristic,and so on was studied.The research result shows that the main causes of accidents are related to driving performances,such as over-loading,significant speed variation among various types of vehicles,driving inattentively and following too closely.In view of this,the paper puts forward the corresponding measures for safety improvement from aspects of engineering and traffic management.
