With the increasing demand for transportation, more low speed large-scale trucks get into expressway and force the following vehicles to decelerate, which leads to an inefficient traffic flow. In view of this, this paper attempts to determine, based on the traffic flow wave theory, the state changes of traffic flow caused by on-road large-scale trucks, through a quantitative analysis of the relationships among the length of lane occupied by large-scale trucks, the jamming time, and the blocked vehicles, indicates the extent to which the on-road trucks affect the traffic flow, and finally points out the importance of a clear division of large-scale truck lanes, the importance of the expressway minimum speed and that of the limited expressway truck proportion, with an aim to provide the basis for expressway mixed traffic flow management.
