Quality Management Methods for Real-Time Traffic Information

Quality of real-time traffic messaging is mostly defined in terms of quantitative or technical characteristics that relate almost exclusively to the technical broadcasting and availability of the information. This pays insufficient attention to the traffic messages’ content and conformity with the real situation experienced by drivers. Accuracy of content however is a decisive factor in customer satisfaction and acceptance. In this paper, four different methods for quality management of real-time traffic information are explained and compared in detail: QKZ-Method, QFCD-Method, QBENCH-Method and ASDA/FOTO Travel Time Method.
