Vehicle speed and path planning system and method thereof

Abstract

The invention discloses a vehicle speed and path planning system and a method thereof. A master server of the system gathers all traffic lamp information in a city and position information of a user terminal. After a user inputs a target position on the user terminal, the user terminal acquires the traffic lamp information from a current position to a target point from a server in real time. Thenthe user terminal analyzes a current signal for determining a vehicle speed and a driving path for preventing waiting in front of a red lamp in a vehicle driving process. The vehicle speed and path planning system and the method thereof have advantages of optimizing the driving path, greatly reducing waiting time of the user in front of the signal lamp, and furthermore greatly reducing unnecessaryenergy wastage. Through reasonable path planning, vehicles are shunted, and a certain shunting function can be performed on the road with overhigh traffic volume. The system and the method have advantages of greatly saving social resource and improving passing efficiency of urban traffic.

Description

technical field [0001] The invention belongs to the field of traffic command, and relates to a vehicle path planning system, in particular to a vehicle path planning system and a control method that utilizes traffic light information to determine in real time the shortest time between targets or the most energy-saving use. Background technique [0002] In the modern urban traffic management and governance scheme, the role of traffic lights is undoubtedly huge, but often traffic lights will also bring some unnecessary waiting and congestion. At the same time, braking, idling and restarting while waiting for the red light will cause a lot of waste of energy and time, so people often accelerate too hard in order to grab the first few seconds of the red light, which also leads to many tragedies. [0003] This situation shows that how to save people's time waiting for traffic lights, so that people can waste as little time and energy as possible to reach their destination, is a p...

At the same time, braking, idling and restarting while waiting for a red light will cause a lot of waste of energy and time, so people often speed up in order to grab the first few seconds before the signal light turns red, which also leads to many tragedies.
