Bus signal priority control method and device based on ecological benefits and storage medium

The invention discloses a bus signal priority control method and device based on ecological benefits and a storage medium, and the method comprises the steps: obtaining a signal-priority first bus set and an intersection signal timing scheme of each first bus according to a preset intersection signal timing constraint condition when a predicted phase state is not a green light phase; calculating the increased time cost of the intersection passengers and the increased ecological cost of the intersection passengers of each intersection signal timing scheme; and by taking the minimum time cost as a target and the ecological cost as a constraint, screening out an optimal intersection signal timing scheme from all the intersection signal timing schemes, and feeding back the optimal intersection signal timing scheme to a control center of the intersection signal lamp, so that the intersection signal lamp executes the optimal intersection signal timing scheme. By adopting the embodiment of the invention, the relatio
