A new efficient monitoring system is designed for highway traffic meteorological observation stations.This system is composed of two parts,the real-time meteorological data storage procedure,which is designed and developed by multi-threading,and the modified and reused open-source ZedGraph drawing controls.Backed up with the use of Oracle10g database,the monitoring system integrates the real-time meteorological data storage and data extraction and display.The system realizes the storage and backup of a large volume of meteorological data and provides basis for traffic management and warning decision through its monitoring and display function.Practical application results show that this system is feasible and effective in reducing the impact of meteorological disasters on highway traffic.
