eMobility – Strategic Applications AgendaAnnex B44. Dynamic signposts with integrated congestioninformation - dWiStaBackground and ObjectivesA dWiSta system was planned and installed as a pilot project in the Leipzig region at three federal motorwayinterchanges and eight motorway junctions. The acceptance of such information-based signposts was to beinvestigated, in particular with regard to their use at motorway junctions, and their effect was to be evaluatedfrom a traffic control and economic point of view. An example of a cost-benefit analysis for the installation andoperation of dWiSta at a motorway junction in the Leipzig region showed a high benefit ratio depending on thefrequency of events, the traffic load and the detour factors. The results of the investigation consist of specificrecommendations concerning the further implementation of dWiSta in the Leipzig region and of generallyapplicable usage criteria for dWiSta at federal motorway junctions.Participantshttp://www.bast.de/cln_005/nn_74636/DE/Publikationen/Infos/2007-2006/18-2007.htmlFurther InfoBundesanstalt für StraßenwesenPostfach 10 01 5051401 Bergisch GladbachInfo-ServiceTelefon: 02204 43-327Fax: 02204 43-694E-Mail: info@bast.de45. Use of new technologies for traffic information andguidance systemsBackground and ObjectivesThe provision of modern information technology to control traffic has added a new dimension to road trafficengineering in recent years. The current level of development regarding telematics in traffic is characterised byattempts to prove the functionality of numerous technical elements and sub-systems. There has recently been arapid development of private traffic information services which are largely based on mobile radio systems.Analysis of the current developments and demonstrations of their potential for contributing towards an integratedtraffic management system is necessary from the perspective of traffic science, which has to deal with the trafficengineering strategies for the operation of new guidance systems. The aim of the present project was to developsolid concepts for the use of new technologies in different scenarios.Participants161
