LOW‐COST COOPERATIVE ROAD WEATHER MONITORING STATION

摘要

New concept of Cooperative Road Weather Monitoring Station is presented in the paper.rnCooperative systems in Traffic & Transportation (Intelligent Transportation systems) arernbased on communication between vehicles and infrastructure (Roads equipment). It isrnwell-known V2X Technology. The exchange of data between the vehicles andrninfrastructure is imperceptible by drivers until a potentially dangerous situation is detected,rnat which moment the drivers concerned will receive an alert. The sensors for temperaturesrnof the air, road surface and road structure, wind speed and direction, humidity, intensityrnand the state of precipitation, visibility (and other options) are connected to the roadrnweather monitoring station. Road weather information are analyzed and assigned to somernroad condition categories by the Local processing unit. Some recommendations of speedrnlimits and other possible warnings to driver (Emergency warning system for vehicles) arernsent via DSRC (Dedicated short‐range communications) to vehicles on the road. Also, thernspeed limits and possible warnings can sent to variable message signs near the roadrnweather monitoring station.
