Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0034] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0035] It is of great significance to predict road weather, and road weather includes: road surface temperature and road surface condition. Among them, the unfavorable road surface conditions that have a significant impact on traffic safety mainly include: wet and slippery road surfaces, icing, snow, icing, frost, water, etc. These unfavorable road surface co...

Abstract

The invention provides a road weather prediction method and device, electronic equipment and a storage medium. The method comprises the following steps: processing the weather forecast information ofa first future time period, historical road surface temperature observation information of a first past time period and historical road surface condition observation information of a second past timeperiod by using a pre-established road surface temperature prediction model according to acquired geographic information of a to-be-measured area, predicting to obtain road surface temperature prediction information in a second future time period, and then, obtaining road surface condition prediction information. According to the embodiment of the invention, the geographic environment, the weatherforecast information, the historical road surface temperature and the historical road surface condition are combined, the established road surface temperature prediction model is utilized to predictthe road surface temperature, and thus, the road surface temperature prediction information of the to-be-measured area can be accurately obtained. Furthermore, on the basis of obtaining the road surface temperature prediction information, the subsequent road surface condition is accurately predicted.

Description

technical field [0001] The present application relates to the field of surface condition prediction, in particular, to a road weather prediction method, device, electronic equipment and storage medium. Background technique [0002] Under unfavorable road surface conditions such as icy and slippery road surfaces, traffic accidents occur frequently, and the probability of traffic accidents per unit time is more than ten times or even dozens of times higher than that under dry road conditions. Unfavorable road conditions will not only cause direct loss of life and property, but also reduce the efficiency of transportation. Thus, accurate predictions of pavement surface conditions are of great significance in forecasting service needs. [0003] The traditional road surface weather forecast system directly maps the weather forecast to the road network. This preventive method often has large errors and a large number of missed reports. Contents of the invention [0004] The pu...
