Ensuring Absolute Transit Priority Through Trajectory Based Control of Connected and Automated Traffic

This paper proposes a Trajectory Based Control (TBC) method for connected automated traffic. The goal is to ensure absolute transit priority without heavy sacrifices from the general traffic. To achieve the goal, a Bus Priority Lane (BPL) is designed. The BPL is open for general traffic if needed. To implement the BPL, the proposed TBC controller would control whether and how general traffic accesses the BPL so that the sacrifice of general traffic is minimized. The proposed TBC controller is evaluated through comparison against the non-control baseline that ensures absolute transit priority with a Dedicated Bus Lane (DBL). Sensitivity analysis is conducted under different congestion levels. The results demonstrate that the proposed TBC controller outperforms the non-control baseline in terms of throughput benefits.
