Embodiment Construction

[0010] The present invention uses smart terminals such as smart phones, GPS navigation, car navigation, tablet computers, notebook computers and other smart terminal equipment to install application software or programming chip programs, and send a speed reference prompt through the smart terminal to prompt the vehicle driver to refer to Speed ​​up to the traffic light ahead, which happens to be a green light.

[0011] Each traffic light has a transformation rule. According to the transformation rule of a certain traffic light, the green time period of the traffic light can be calculated within a certain period of time in the future. According to the current vehicle position and road map, the distance between the vehicle and the red light intersection can be calculated. According to the GPS positioning module, the current position and speed of the vehicle can be calculated in real time. According to the current vehicle position and speed, the distance from the red light inter...

Abstract

Provided is an intelligent transportation system which can timely provide vehicle speed reference and is used for achieving that when a vehicle driver is prompted to travel to a position of a front traffic light according to a reference speed, the traffic light is precisely in a green light passage state. The intelligent transportation system comprises a traffic light control data collection module, a traffic light timing sequence module which is used for working out a timing sequence of each traffic light in a certain time in the future according to a traffic light changing rule, a computer data processing network service interface module and a mobile data communication module. Vehicle speed reference prompting is timely provided for the vehicle driver through an intelligent terminal to achieve that when the vehicle driver is prompted to travel to the position of the front traffic light according to the reference speed, the traffic light is precisely in the green light passage state, and the purpose that the vehicle driver does not need to park to wait for the red light is achieved. The intelligent transportation system can help vehicles to save fuel oil, achieves effects of energy saving and emission reduction, and meanwhile improves passing efficiency traffic light crossroads.

Description

technical field [0001] The invention relates to an intelligent traffic system that provides real-time reference prompts of vehicle speeds to prompt vehicle drivers to drive to the traffic lights in front at the reference speeds, which is just the state of the green lights. technical background [0002] When a vehicle encounters a red light, it must go through the process of braking, stopping, and starting to accelerate. A lot of energy is lost in this process. This also means that when encountering a red light, a certain amount of fuel will be consumed in the process of stopping and restarting. In addition, when the vehicle is waiting for a red light, the engine is working and there will be a certain amount of fuel consumption. After the red light turns green, the vehicle will also spend a certain amount of time in the starting process, and the time for the vehicle to pass through the traffic light is extended. [0003] If there is a system that can provide a real-time sp...
