A road disastrous weather monitoring and vehicle early warning method

Abstract

The invention relates to a road disastrous weather monitoring method. Based on design of an existing traffic weather station, Doppler meteorological radar observation data are introduced. By means of characteristics such as large range and high time resolution in the Doppler meteorological radar observation data, defects in existing road weather monitoring are settled, and coverage monitoring for no-monitoring areas without the traffic weather station is realized, thereby effective coverage rate and accuracy in road weather monitoring. The invention further relates to a vehicle early-warning method based on road disastrous weather monitoring. Furthermore a road disaster range is transmitted to drives on the road. In-advance early-warning in short time can be realized. Individualized vehicle condition information is combined with a disastrous weather risk, thereby realizing more accurate service to a vehicle user group, realizing efficient, in-time and accurate transmission of road emergent disastrous weather information to the vehicle drivers, and ensuring high driving safety on the road.

Description

technical field [0001] The invention relates to a road disastrous weather monitoring and vehicle early warning method, belonging to the technical field of meteorological monitoring. Background technique [0002] For the monitoring of road disastrous weather, traffic weather stations are mainly deployed on roads to collect precipitation, visibility, road surface temperature, road surface conditions, wind speed and other disastrous weather information. However, due to the limited number of traffic weather stations, the provision is mainly for the area on the expressway line, and the observation of the surface area cannot be achieved. At the same time, the existing road speed limit standards treat the speed limit of vehicles indiscriminately, making it impossible for vehicles to reasonably avoid risks according to their own particularity. In addition, the traffic and road weather has the characteristics of suddenness. The traditional road electronic sign display needs to wait ...

Problems solved by technology

However, due to the limited number of traffic weather stations, the provision is mainly for the area on the expressway line, and the observation of the surface area cannot be achieved.

At the same time, the existing road speed limit standard treats the speed limit of vehicles indiscriminately, making it impossible for vehicles to reasonably avoid risks according to their own particularity.

In addition, the traffic and road weather has the characteristics of suddenness. The traditional road electronic sign display needs to wait for the road management personnel to release it based on visual inspection, which has the disadvantage of slow response speed.
