Severe Weather Monitoring and Early Warning System Solution

1. Overview

The development of highway transportation has an increasingly important impact on the national economy and carries more and more transportation tasks. However, with changes in weather, especially severe weather conditions, the driving range of vehicles on highway transportation is affected. A huge risk has arisen, which not only seriously affects transportation, but also seriously affects the safety of people's lives and property. Improving the traffic capacity of highways, enhancing the ability to respond to traffic environment degradation, and ensuring the safe, efficient, and smooth normal operation of highways have become issues of great concern to the whole society.

2. The Impact of Bad Weather on Traffic

Security Impact

Fog, snowstorms and icy roads have become road killers for traffic safety.

Economic Impact

In weather conditions such as heavy fog, snow, and ice, highway traffic is often closed to effectively prevent traffic accidents, but the closure directly brings economic losses.

Social Influence

Highway traffic accidents caused by disaster weather are generally serious, with large casualties and negative social impact.

3. System Introduction

The system adopts a monitoring network operation mode to continuously obtain meteorological information from multiple points along the line, feed it back to the monitoring center, and compare the detection data with predetermined judgment conditions to determine whether there is fog, ice, snow and other severe weather; when determining severe weather Under certain circumstances, the predetermined indicator library is called, and the control level of the detection indicator is determined by comparing the detection data with the predetermined indicator library; finally, the corresponding control strategy is called from the predetermined strategy library according to the indicator control level to deal with severe weather conditions. The impact caused by highway traffic, so as to ensure the operation of highway traffic around the clock.

4. System Composition

This system consists of the following units:

(1) Information collection unit: The information collection equipment adopts traffic weather station equipment, including visibility meter, remote sensing road condition detector, wind speed and direction sensor, temperature and humidity sensor, rainfall sensor, etc.

(2) Information release unit: Convert monitoring strategies into specific warnings and control instructions, and release them to drivers through field equipment; information release equipment mainly relies on variable information board display, etc.

(3) Monitoring networking software: computer server and monitoring platform software

(4) Public service platform: Provide road safety services through network information push, mobile APP and other methods.

(5) System support unit: including control unit, transmission unit, power supply and distribution unit, and information processing unit.
