U.P.B. Sci. Bull., Series C, Vol. 77, Iss. 3, 2015 ISSN 2286-3540 TRANSMISSION OF POLLUTION DATA TO TRAFFIC MANAGEMENT SYSTEMS USING MOBILE SENSORS Maria Claudia SURUGIU 1 , Răzvan Andrei GHEORGHIU 2 , Ionel PETRESCU 3 Modern traffic management systems use, in addition to data on the number and categories of vehicles, information on pollution in order to include them in the algorithm used and to determine avoidance of areas with out of scale parameters. These data can be collected at road junctions, using fixed detectors, or between them, using sensors placed on vehicles, such as public transport vehicles. Stored information can then be transferred to the traffic management system at intersections through traffic controllers. This paper presents a solution for this communication, performing calculations necessary for the communication channel. Keywords: urban pollution, traffic management systems, pollution detectors, wireless sensor network, data transmissions 1. Introduction Pollution is a real problem in cities, especially the one caused by road traffic. To deal with this, traffic management systems started to include in their algorithms for traffic guidance information about polluted areas. The goal is to achieve a redistribution of emissions so areas with exceeded pollution would not exist anymore. In order to do this pollution sensors must be used. These may be fixed or mobile, gathering data in road junctions or between them. Mobile sensors may be installed on public transport vehicles and can send the data to traffic management system in intersections, by communicating with traffic controllers. Communication parameters have been evaluated in order to determine the most suitable communication channel capable of ensuring a fast and reliable connection in intersections for data exchange. 1 Senior Lecturer, Dept. of Telecommunications and Electronics in Transports, University POLITEHNICA of Bucharest, Romania, e-mail: claudia.surugiu@upb.ro 2 Junior Lecturer, Dept. of Telecommunications and Electronics in Transports, University POLITEHNICA of Bucharest, Romania, e-mail: andrei.gheorghiu@upb.ro 3 Junior Lecturer, Dept. of Telecommunications and Electronics in Transports, University POLITEHNICA of Bucharest, Romania, e-mail: npcrank@yahoo.com
