Abstract
The invention discloses a bus transit lane time division sharing method. LED indicating lamps are arranged on lines for separating bus transit lanes and common lanes at intervals. Vehicle detectors for detecting whether buses pass through or not are arranged on the bus transit lanes and correspond to the LED indicating lamps in a one-to-one mode, and wide-angle panoramic cameras for detecting whether the buses go into special bus inlet lanes or not are arranged on the road edges at the intersection positions. The vehicle detectors detect whether buses pass through or not and indicate shifting of two working states of the LED indicating lamps. The wide-angle panoramic cameras detect whether the buses go into the special bus inlet lanes or not and confirms whether intersection signal control machines adopt bus transit signal preference or not. The bus transit lane time division sharing method fully utilizes existing road resources, permits social vehicles to use the bus transit lanes on the premise of bus transit preference and under the condition that the utilization rate of the bus transit lanes is not high, achieves time division sharing of the bus transit lanes and decreases vehicle delay.
