Road condition broadcasting method and system based on cloud short-term path prediction

Abstract

The invention discloses a road condition broadcasting method and system based on cloud short-term path prediction. The method comprises the following steps: a vehicle-mounted terminal acquires vehicleposition coordinates, and the coordinates are sent to a cloud server through wireless communication; the vehicle-mounted terminal converts the vehicle position coordinates, the cloud server calculates the driving distance of the vehicle according to the position data received in real time, and the received vehicle position is saved to a database; based on an RNN trained by successive data of thedatabase and the current travel data, the cloud server predicts the driving path of the vehicle; the road condition information of road sections within a radius coverage area and the road intersectiongenerated by the predicted vehicle travel paths are taken, and the congestion road section information which needs to be broadcasted can be acquired; and through a TTS technology, the vehicle-mountedterminal converts formed text information to voice to be broadcasted. Delays caused by accidents or road congestion and the like can be reduced, a vehicle flow can be reasonably and effectively evacuated, the time on the road is saved, and safety hazards are reduced.

Description

technical field [0001] The invention relates to a road condition broadcasting method and system based on cloud short-term path prediction, belonging to the field of intelligent transportation technology. Background technique [0002] The traditional real-time road condition broadcast generally receives specific coded real-time traffic information on the vehicle terminal, and combines it with the navigation system in a visual way to display the information to the driver. This way of transmitting traffic information requires drivers to put in a lot of effort to interact, which affects driving safety. On the contrary, some real-time road condition broadcasting methods that do not use the navigation system have the characteristics that the traffic information provided lacks pertinence, and a large amount of invalid information is provided to the driver. Contents of the invention [0003] The purpose of the present invention is to provide a road condition broadcast method and ...
