Real-time traffic information notification system and method, and vehicle-mounted terminal

Abstract

The invention relates to a real-time traffic information notification system, which comprises a traffic information processing sub-system, a user information tracking sub-system and a traffic information notification sub-system, wherein the traffic information processing sub-system acquires real-time road traffic information according to a preset period, matches the real-time road traffic information and updates the set early-warning virtual boundary of a congestion section; the user information tracking sub-system acquires geographic information of a vehicle-mounted terminal according to a preset period, matches the geographic information with an electronic map to judge whether the vehicle-mounted terminal is positioned in the early-warning virtual boundary, and calculates a smooth road path if the vehicle-mounted terminal is positioned in the early-warning virtual boundary; and the traffic information notification sub-system transmits the current real-time congestion information in a text mode to the vehicle-mounted terminal. The acquired vehicle position is matched according to the set early-warning virtual boundary, and the congestion information is timely transmitted to the vehicle-mounted terminal and displayed by the vehicle-mounted terminal, so that convenient and accurate driving guidance is provided for a driver, the urban traffic congestion pressure is relieved and tail gas emission is reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a real-time traffic information notification system, method and vehicle-mounted terminal. Background technique [0002] Traffic congestion has become an important problem faced by big cities. Providing real-time traffic information to users through the ever-growing mobile communication technology can alleviate urban traffic congestion and reduce exhaust emissions to a certain extent. [0003] There are mainly the following ways for vehicles to obtain real-time traffic information: [0004] 1. Drivers listen to road information through the traffic broadcast channel, but this method is not targeted and cannot be understood at any time when needed, and the amount of information is relatively small; [0005] 2. Users can query real-time traffic information through the website map, but this method can only be inquired before departure, and cannot be understood in real time while dri...

AI Technical Summary

Problems solved by technology

[0004] 1. Drivers listen to road information through the traffic broadcast channel, but this method is not targeted and cannot be understood at any time when needed, and the amount of information is relatively small;

[0005] 2. Users can query real-time traffic information through the website map, but this method can only be inquired before departure, and cannot be understood in real time while driving, and because traffic information changes very quickly, non-instant traffic information may provide users with more help in driving limited;

[0006] 3. Obtain real-time traffic information through the car navigator, which is very intuitive, but for some car navigators without screens or black and white screens and local lack of electronic maps, it may not be able to show clear and meaningful traffic to drivers information, and requires the driver to check the screen at any time, which is not conducive to driving safety
