Agent-Based Simulation of Eco-Speed Controlled Vehicles at Signalized Intersections
Summary Information
Using a simulation model this research demonstrated the concept of an eco-speed control system enabled by V2V and I2V communications at an urban intersection in Blacksburg, Virginia. Using field data such as roadway vertical profile, roadway surface condition, traffic volumes, and traffic signal timing information, an agent-based simulation model was constructed to evaluate how an eco-speed control system can optimize vehicle trajectories using information broadcast through V2V and I2V communication systems at an intersection to minimize fuel consumption and improve mobility under varied traffic volumes and market penetration levels.
The following conclusions were derived from 38 simulation runs:
- Eco-speed control is able to reduce the overall fuel consumption of vehicles by approximately 30 percent in the vicinity of signalized intersections.
- The increase in average travel-speed for all cases was 210 percent.
- Fuel savings were greater for the major street compared to the minor street at the test intersection due to the short red-time for the major approach.
Note that benefits will vary depending on the trip profile including the number of intersections and total trip length.
