 This paper proposes a dynamic right-of-way priority control approach, PDRE versus, for emergency vehicles to improve their efficiency on basic road sections and cities. PDRE versus uses a movable physical function area in front of the emergency vehicles to prevent connected vehicles from entering a lane or to request them to change lanes to avoid a collision. Additionally, a dynamic monitoring area is set up in front of the emergency vehicles to monitor the connected vehicles headway distribution in the inner lane. When connected vehicles enter the buffer area, a lane change request is sent and the traversal search method predicts the optimal time and rate of speed to change lanes and guide the connected vehicles ahead of the emergency vehicles to merge into the target gap. Simulations with the Sumo platform showed that the priority of the PDRE versus reduced the average delay of the emergency vehicles by over 70% under certain conditions without significantly increasing the delay of the connected vehicles. Furthermore, the simulations demonstrated that the long buffer area was suitable for low volume conditions whereas the short buffer area was suitable for high volume conditions.
