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

Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the present invention has designed a kind of road disastrous weather monitoring method, based on each traffic weather station that distance is set on the road, realizes the monitoring of disastrous weather section area for the whole road, wherein, disastrous weather section area includes rainfall For the disaster road section area, in actual application, the following series of steps are executed in real time to realize real-time monitoring and updating of the rainfall disaster road section area for the whole road;

[0032] Step A. Obtain the rainfall in the road area monitored by each traffic weather station, and then enter step B.

[0033] Step B. Determine whether there are traffic weather stations whose rainfall is greater than the preset rainfall disaster threshold, and if so, defi...

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 ...
