Dedicated Bus Lane (DBL) is a typical strategy to ensure priority for public transportation. However, when the frequency of bus departures is low, the DBL often remains vacant, reducing the efficiency of traffic utilization. Variable bus lane (VBL) strategy allows for the provision of service to social vehicles in specific scenarios, aiming to alleviate traffic congestion and improve emission efficiency at intersections. To analyze the impact of this strategy on dynamic queuing behavior and traffic efficiency at an isolated intersection, this paper proposes a multidimensional stochastic queuing model. The model incorporates various factors such as traffic demand, signal timing, bus arrival time, and the length of the variable area at intersections. By examining the steady-state distribution of queue length and calculating performance indicators, the effectiveness of VBL in improving intersection performance is evaluated. Numerical simulations have demonstrated that the proposed model accurately describes the vehicle queuing process at intersections under different conditions. Theoretical analysis confirms that the implementation of VBL strategy can effectively improve traffic efficiency at intersections and minimize the queue length of vehicles. [ABSTRACT FROM AUTHOR]

From the perspective of driver's visual characteristics, based on the influence of the two-point preview steering decision and stopping sight distance on the car-following behavior in small-radius curves, the new car-following model considering driver's desired visual angle on curved roads is proposed in this paper. The dynamic performance and safety of the new model are explored subsequently. First, the neutral stability condition of the new model is derived by linear stability analysis. Then, the evolution process of small disturbance of traffic flow is analyzed by numerical simulation, and the same conclusion of linear stability is obtained. That is, introducing the effect of the driver's desired visual, designing a reasonable curve radius, and the large vehicle becoming the leading vehicle is conducive to improving the stability of the traffic flow and effectively alleviating traffic congestion. Finally, the safety of the new model is analyzed by using the stopping sight distance, which shows that the newly introduced factor can also effectively improve the safety of car-following behavior on curved roads. • The desired visual angle following model for small radius curves is proposed. • Two-point preview steering decision is considered in the new car-following model. • The safety of the car-following model was evaluated using the stopping sight distance on the curved road. • The stability condition of the new model is deduced.
