Abstract
A method of avoiding collisions and preempting traffic signals, including the steps of predicting a first likely travel route of a first vehicle along established roadways; predicting a second likely travel route of a second vehicle along the established roadways; preempting a normal operation of at least one traffic signal at an intersection of roadways along at least one of the first likely travel route and the second likely travel route allowing at least one of the first vehicle and the second vehicle to traverse the intersection; and determining whether both the first vehicle and the second vehicle will be at the intersection within a predefined time interval of each other.
