Abstract
Typical points are selected on Ganmo Highway, the only bidirectional four-lane highway of Xinjiang Production and Construction Corps (hereinafter referred to as “Xinjiang Corps”), so as to measure the speeds of vehicles on the overtaking lane and corresponding inside clearances. The relationship between the inside clearances and speeds of different types of vehicles is studied by mathematical statistics so as to establish a model of the relationship between inside clearances and speeds. Based on the collision deformation of different barrier types and the demand for the actual functions of the central strip, how to select the width of the central strip and the barrier type of the arterial highway of Xinjiang Corps is analyzed. According to the results, there is a linear relationship between inside clearances and speeds of vehicles; monolithic concrete barriers require a small width of the central strip and they are cheap on the whole and suitable for the corps area.
