Traffic States under Influence of Different Vehicle Types on Freeway with Two Unidirectional Lanes

Abstract:

The high proportion of heavy vehicles on Chinese freeway brings important effects to the operation of freeway and makes the traffic very complex. The exhibition and mechanic of the influence between different vehicle types vary under different traffic flow and heavy vehicle proportion. In this paper, field survey was carried out and the characteristic of Chinese mixed traffic was gotten. Based on the phenomenon observed in the field survey, models were built to analysis the mechanic of the influence between different vehicle types. The influence states were divided into four aspects according to different exhibition and mechanic, that is: free flow condition, independent heavy vehicle impact, heavy vehicles and cars in different lane, drive in disorder. The influence states will transfer with the temporary variation of traffic flow composition. It is result from the self-organizing behavior of vehicles which pursue higher speed and brings dynamic change of capacity and level of service in time and space.
