Bus ecological driving guiding method based on vehicle-road cooperation

Abstract

The invention discloses a bus ecological driving guiding method based on vehicle-road cooperation, which comprises the steps: obtaining the real-time state of an intersection signal lamp before a current bus is ready to start at a bus station, and then selecting a more ecological driving mode according to the signal state of a front intersection to pass through the intersection. Meanwhile, in combination with the passenger carrying rate threshold value and the waiting time threshold value of the public transport vehicles, the waiting time of part of the public transport vehicles which should stop at the intersection is reasonably transferred to the waiting time of the public transport vehicles at the station, so that the carrying efficiency can be improved. According to the invention, the phenomena of starting and stopping, idling, rapid deceleration, rapid acceleration and the like of the public transport vehicle at the intersection can be reduced, so that vehicle delay, fuel consumption and tail gas emission are reduced. According to the method, the environment can be protected, the safety and carrying efficiency of road driving can be improved, the ecological and environmental protection concepts are met, and sustainable development of traffic is facilitated.

Description

Technical field [0001] The present invention relates to the field of intelligent traffic control, and in particular, a bus ecological driving guiding method based on a car road synergistic. Background technique [0002] Ecological driving is a way to drive a car in a way of protecting the environment, such as keeping the vehicle at a constant speed, slow acceleration, and brakes. With the development of social economy, there are more and more car ownerships, and the road traffic pressure is increasing, and the problem of road traffic congestion has gradually become one of the main problems that hinder urban development. Developing public transportation is the main measures to slow down urban traffic congestion, and the ground bus is a public transportation of people, and the intersection of the road is an important part of urban roads. It often carries large traffic volumes. Since there is a traffic light in the intersection, the bus often has a phenomenon such as stagnation, dec...

Problems solved by technology

[0003] Existing research mainly focuses on improving the operating efficiency of public transport vehicles, such as setting up dedicated bus lanes, setting up bus priority signals, and setting up "green waves" to pass through intersections. Although these measures have improved the operating efficiency of public transport vehicles, they have not been very effective. Realize the eco-driving purpose of reducing fuel consumption and exhaust emissions
