The invention discloses a
bus priority
signal control method based on multiple requests in a vehicle networking environment, aiming at overcoming problems that a current
bus priority
signal control method has low prediction precision and cannot satisfy priority of multiple buses. The
bus priority
signal control method based on multiple requests in the vehicle networking environment includes the following steps: 1, collecting real-
time information in the vehicle networking environment, and detecting multiple
bus priority requests; 2, determining running statuses of the buses and determining whether the bus is behind a timetable; 3, predicting the time when the bus arrives at an intersection; 4, determining a signal control scheme that satisfies priority of multiple buses, including 1) solving
green time required to meet the priority requests of multiple buses, 2) calculating a
bus priority signal control scheme for a
current period, 3) solving a signal control scheme of the next periodbased on a
green time compensation algorithm, 4) calculating
total delay of the intersection of each signal control scheme, and selecting the priority signal control scheme with the smallest
delay.
