Investigation and Analysis of Two-Lane Highway Driving Track in Turn

摘要

Six simple curves were selected to survey driving track because of the features of many collision accidents in two-lane highway curves. Based on the analysis of trajectory excursion about large trucks, buses, small trucks and small passenger cars in the upward and downward direction, the characteristics of vehicle lateral excursion of different types were researched. And the relationship was established among vehicle types, radius of curve and cross-area tracks by measuring cross-area tracks of different radius. The result may provide some references for geometric design in two-lane highway.
