Abstract: This patent provides a process that utilizes the vehicle to infrastructure communication process to gather anonymous vehicle trajectories that describe vehicles approaching a signalized intersection. This information is used to project forward in-time the positions of vehicles to calculate the optimal time to change the traffic signal at a point that will minimize the delay to the traffic.
