Intermittent bus lane control method based on dynamic clearance

The implementation effect of intermittent bus lane (IBL) is closely related to the setting of their clearing distances, and existing studies mainly focus on fixed clearing distances, which are difficult to adapt to real-time road traffic conditions. To address this, considering the characteristics of the vehicular networking traffic environment, a control method for IBL based on dynamic clearance is proposed, and a control model for IBL considering the queuing at downstream intersections is constructed. According to the location of connected vehicles on the IBL and the degree of impact on the operation of buses, different lane-changing rules and decision models are formulated. The SUMO simulation experiment is used for verification, and the results show that the proposed control method model can reduce bus delays, improve bus speed, and to some extent, enhance the traffic capacity of the IBL, without excessively increasing the delay impact on social vehicles. At the same time, this control method is more sensitive to the penetration rate changes under high traffic volume.
