Method and system for dynamically sharing buses-only lane resources based on IOT (Internet of Things)

Abstract

The invention discloses a method and system for dynamically sharing buses-only lane resources based on the IOT (Internet of Things). The method comprises the steps: adding a dedicated signal lamp forindicating whether a social vehicle can enter a buses-only lane or not at an intersection of the screened buses-only lane; enabling the dedicated signal lamp to remain red till the buses in all bus fleets enter the current intersection, and calculating the remaining passing time of an original signal lamp according to the straight passing time duration of the original signal lamp and the differences between the moments when all bus fleets pass through the current intersection; controlling the state of the dedicated signal lamp through judging the remaining passing time of the original signal lamp and the size of a time duration clearing threshold value of the dedicated signal lamp, and further determining whether to allow a social vehicle in straight running to use the buses-only lane or not. The method improves the utilization efficiency of the space-time resources of the roads.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and in particular relates to a method and system for dynamically sharing bus lane resources based on the Internet of Things. Background technique [0002] With the rapid development of urbanization, the number of urban motor vehicles continues to grow. Due to limited land resources, the road construction period is long and the cost is huge. Increasing road resources to alleviate traffic congestion cannot meet the sustainable development of traffic. Vigorously developing public transport is the fundamental way to alleviate traffic congestion, and the setting of bus-only lanes is an effective means to ensure bus priority. However, according to field research, it is found that the utilization rate of bus-only lanes is low during certain periods of time, and the adjacent social lanes are congested, resulting in a waste of space-time resources on dedicated lanes. Therefore, the concept of dynami...

AI Technical Summary

Problems solved by technology

Existing studies on dedicated lane sharing still use the traditional concept of time-sharing dedicated bus lanes, the theory and algorithm are relatively simple, the control of social vehicles depends on experience rather than accurate calculations, and the requirements for the setting of road facilities are relatively high. Fuzzy, the calculation of relevant parameters is not rigorous enough, the sharing rate of bus-only lanes is low, the effect on improving traffic congestion is extremely limited, and the operability is not strong, so it is difficult to promote and implement on bus-only lanes on a large scale, and the social benefits are not prominent enough
