Lane variable time division multiplexing method guaranteeing bus priority and lane variable time division multiplexing system thereof

Abstract

The invention discloses a lane variable time division multiplexing method guaranteeing bus priority. LED signal indicating lamps used for indicating whether social vehicles can be driven into a bus lane are arranged between the first to the Nth road segments; a vehicle recognition unit used for detecting existence of passing of buses registered in advance is arranged on each road segment, and the green light of the LED signal indicating lamp of the Nth road segment is on if the vehicle recognition unit of the Nth road segment does not recognize that there is no bus driven on the (N-1)th road segment; and a control unit display conversion of the LED signal indicating lamps. The invention also provides a lane variable time division multiplexing system guaranteeing the bus priority. Opening and closing of the bus lane are dynamically controlled through the vehicle recognition units and the LED signal indicating lamps so that the passage capacity of the road can be effectively enhanced; besides, green and red switching of the LED signal indicating lamps is controlled by responding to any one of the two conditions through the control unit so that the congestion situation of the social vehicles on the bus lane can be effectively avoided.

Description

technical field [0001] The invention relates to the field of traffic lane control, in particular to a lane-changing time-division multiplexing method and system for ensuring bus priority. Background technique [0002] In recent years, with the continuous improvement of people's living standards in our country, the number of motor vehicles has increased sharply, which has caused the rapid expansion of the demand for traffic in various places, and the problem of traffic congestion has become increasingly serious. However, the phenomenon of low utilization of lanes and waste of road resources has not been solved. improve. Existing road utilization methods generally only statically stipulate the use authority of each lane throughout the day or during certain periods of the day. Therefore, it is necessary to vigorously develop public transportation and determine the development strategy of "public transportation priority" from the perspective of "people-oriented, efficiency firs...

AI Technical Summary

Problems solved by technology

However, the original signal scheme of the intersection is changed, and the signal control scheme is adjusted by extending the green light and advancing the green light. This signal priority method is at the cost of prolonging the waiting time of social vehicles at the intersection, which will inevitably make the originally crowded intersection more crowded. Congestion; some have adopted the dynamic adjustment method, but only according to the real-time driving status of the bus vehicles, there will be situations where social vehicles are congested on the bus lanes

Nowadays, in view of the low utilization efficiency of public transport lanes and the serious waste of road resources, it is necessary to propose a practical method to make full use of various lanes in real time and effectively. The limited road resources are rationally allocated
