On one hand, the passenger car and the freight car have large difference in the aspects of external contour size, total design mass, dynamic property and the like, the difference of the driving speeds of the passenger car and the freight car is large, so that local congestion and slow driving are easily caused, traffic accidents such as rear-end collision and the like are induced, and the freight car generates huge collision energy when the traffic accidents occur, so that serious damage results are easily caused.
On the other hand, compared with a one-way passenger-cargo separation road for two passengers and two passengers, the passenger-cargo mixed traffic road with 4 lanes has smaller traffic capacity compared with the passenger-cargo separation road, and the traffic capacity of the passenger-cargo mixed traffic road is obviously reduced when the mixing rate of the trucks is increased. Therefore, the management and control of the safety and traffic efficiency of the highway freight vehicles are particularly important.
Static management measures of passenger-cargo vehicle lane-by-lane running are adopted on the expressway, and the traffic safety is improved to a certain extent.
However, because the traffic flow has variability and non-uniformity, the road resources are wasted and the traffic capacity is not fully utilized due to a single static management measure. Therefore, the passenger-cargo lane management needs to adopt corresponding dynamic control based on the change of the traffic demand of the expressway.
Therefore, how to improve the fine management level of the lane-dividing driving of the passenger-cargo vehicles by an informatization means and further improve the passing efficiency of the expressway and the traffic safety become technical problems which need to be solved by technical personnel in the field.
