METHOD AND SYSTEM FOR PROVIDING USERS WITH PROMPT INFORMATION, INSTRUCTIONS AND ADVANCED VIRTUAL ROAD SIGNPOSTING ABOUT SUPERVISED ROAD CONDITIONS

摘要

A method provides users with prompt information, instructions and advanced virtual road signposting about supervised road conditions. Application software runs on mobile devices associated to a user on a vehicle travelling a supervised road network with a unique identifier. An application server associates a first vehicle on the road to first information of the unique identifier including mobile device position. The application server collects the first information and the unique identifier and recognizes the application software running on a mobile device. The application server sends to the mobile device a message including information representative of the road traffic condition of the portion of the supervised road network identified by the mobile device position. The application server provides virtual road signposts in fixed locations with associated positions and direction. The mobile device recognizes the virtual road signposts on the supervised road network and receives the recognized virtual road signposts.
