Advancing Traffic Monitoring: Data Fusion Techniques and Innovations for Reliable Road Management

This paper explores the evolution of traffic monitoring systems through data fusion methodologies, tracing the journey from single-system applications to multi-use solutions. We discuss the integration of diverse information types leading to new conclusions and improved methodologies for interpreting data. With a focus on quality assurance and performance verification in Germany's road traffic monitoring technologies, we analyze varying approaches to traffic state prediction in Hesse and assess the benefits of combining different technologies. Lessons learned emphasize ongoing development, architectural challenges, and the competitive landscape among companies.

  1. Data Fusion Some views • Yesterday • Often one system per application • Today • multi use is the issue • Tomorrow • Different information fused with more and new conclusions available • Methods to interpret new information • Other disciplines first • Now within eg. monitoring

  2. Procedures for Test and Quality Assurance of New Technologies for Road Traffic Monitoring, Germany Different having one test method covering all technologiesr, How to verify fused information Different requirements for different applications Model-based Analysis and Prediction of Traffic States in the Secondary Road Network of Hesse, Germany Different approaches using real data and real time models versus measured data only Using different technologies, having advantages and disadvantagies Combination of technologies. In the beginning of a new “fused” area. Development must go on Lessons learnt!

  3. Lessons learnt (2) • The data distributor system – one step further in the direction of robust and versatile traffic monitoring systems, Germany • Architecture, standards - still a challenge, • Should we do less complex cases? • Experiences with data fusion, Scotland • Good idea and it works, • Win-win, require some business models • Using Data on Road Condition and Weather for Short-term Forecasting, Germany • Competion between companies, authority evaluate and compares different approaches
