Abstract
Provided are a vehicle/road interaction signal control method and apparatus, including: expanding the range of an intersection, extending to an upstream intersection along each approaching vehicle direction, and determining signal phases according to traffic flow conditions; acquiring the current speed and the current position of each moving target in each phase; according to the current speed and the current position of each moving target in each phase, calculating the time for each moving target to reach the intersection; according to the time for each moving target to reach the intersection, obtaining a time sequence of the moving targets in each phase for reaching the intersection; according to the time sequence of the moving targets in each phase for reaching the intersection, determining a release order and a release duration for each phase; sending information to onboard terminals.
