Summary Information

This study evaluated the potential of connected vehicles to predict future states of intersection signal control logic to optimize intersection approach speeds and improve fuel economy and trip time while maintaining safe headways between vehicles. The performance of a predictive cruise control (PCC) algorithm was evaluated using a simulation model to emulate 10 intersections having decentralized fixed signal phase and timing (SPaT) control in Greenville, South Carolina.

Simulations were run with and without PCC functions. Performance was evaluated for scenarios with single and multiple connected vehicles operating on the network.

FINDINGS
  • In a suburban driving scenario, predictive cruise control (PCC) equipped vehicles used 47 percent less fuel and generated 56 percent fewer CO2 emissions compared to baseline conditions without PCC. Travel times were similar even though the PCC vehicle traveled a longer distance.
  • In a city driving scenario PCC vehicles used 24 to 29 percent less fuel compared to the baseline.
