BLIDS A Bluetooth-based traffic data collection system supporting international Traffic Management Plans

摘要

With the increase of traffic congestions on highways and in urban areas the automatedsupervision of traffic conditions is getting more and more important. As one part of a researchproject in 2010, the capability of a Bluetooth-based system for incident detection on roadnetworks (BLIDS) was evaluated and tested by cccom Andersen & Moser GmbH.In Austria, the ASFINAG Service GmbH implemented this system into their highway networkin order to gather real time information about the travel time.Using the Bluetooth-based traffic data collection BLIDS, the Traffic Management Centre gets acost effective tool to obtain traffic data that supports the decision-making in case of incidents.Especially the cooperation with neighbouring countries has significantly improved as by usingthe BLIDS system it was possible to set up international traffic management plans (TMP).Accurate information about travel times benefit to road users like choosing alternative routesbefore reaching the Austrian border. It is thus possible to prevent exceeding traffic congestionsin Austria by on-time information concerning current traffic situations.
