The characteristics of traffic flow are recognized by studying the traffic flow variation law of multi-lane tunnel, which provides theoretical support for the management and control of multi-vehicle tunnel on expressway. By collecting traffic flow data of typical multi-lane tunnel, the relationship among running speed, traffic volume and mixing rate of large vehicles is analyzed. It is found that the inner lane has the highest speed, and the outward lane decreases successively. The higher the speed, the greater the speed difference between vehicles; The lower the mixing rate of large vehicles, the greater the velocity difference between vehicles; There is a negative correlation between the speed and the mixing rate of large vehicles. Finally, combined with the traffic volume and the mixing rate of large vehicles, the speed control strategy for different lanes is proposed. |
