How to Measure Traffic Jam or Quality Assurance of Real time Traffic Information Services

Main goal for navigation in the future will not be to provide information on what is the shortest, most economic or fastest way between start and destination only on static map information. As traffic jams is getting a bad reality in our times, realistic information on the traffic situation together with optimized routing to reduce overall waiting time on the trip become more and more valuable all over the world. Value of navigation is how to optimize the route including existing traffic situation. Today service provider and car manufacturer provide traffic information for free or charge a recurring fee. But how to validate, if the information provided is reliable and trustworthy? On the first look, this sounds easy, but as truth is in the details, a lot of hurdles have to be passed for a successful finish. In the paper KPIs will be presented to measure the quality and various methods to determine the ground truth are introduced, traditional ones as to be part of the traffic, using global positioning system (GPS) trackers and more sophisticated ones using satellites making "pictures" with radar of a geographic regions. The pros and cons of the methods are evaluated. The overall aspects are analyzed in an on-going research project.
