Research on the use of incar data for speed estimation


Wednesday December 18th Lisa Priem graduated as a master of science in applied mathematics from Delft University of Technology. She did her research within the ITS Edulab, a cooperation between Rijkswaterstaat and Delft University. Her research was about the use of data from the vehicle (the so-called uCAN data) to estimate the speed of the traffic on a location. Because uCAN data is not available in reality yet, she used simulation to show that about 30% of the vehicles should be equipped with a uCAN unit to get an accurate estimate of the speed. Accurate in the sense that it meets the requirements the Dutch National Data Warehouse for Traffic Information has set. More information and the report can be found on this internet page.

Overview effects traffic management

Gaining knowledge about the effects of traffic management is useful and necessary, both for policy formulation as for traffic operations. On a strategic level decisions are made which alternatives to invest in are most feasible and cost effective and on an operational level the impact of a traffic management scenario is studied to improve traffic operations. In The Netherlands a lot of attention has been paid to the evaluation of traffic management measures. Since 2008 an overview exists in which the results of evaluations studies are presented in a comprehensive manner. Recently, TrafficQuest updated this overview with the latest studies, with makes that the overview contains the results of more than 175 evaluations. The references are given in this list (in Dutch) and the results itself are summarised in a presentation (also in Dutch only). In the future the results will be presented in a more accessible way and also in English.

TrafficQuest attended ISTTT20

The International Syposium on Transportation and Traffic Theory, held in Noordwijk from July 17-19, 2013, was a big succes. The world-leading scientists in traffic and transport presented the most remarkable new resuls of research over the past two years. These scientists are mainly interested in the theoretical aspects of their work. The attendence of TrafficQuest at this conference was relevant to take notice of these new findings and to bridge the gap to practice.

Succesful masterclass about the future

During the 20th "International Symposium Transportation & Traffic Theory", held in Noordwijk from July 16th until Jluy 20th, TrafficQuest organised a masterclass on the future of traffic management. The session was attended by about 35 people from the national and international field of traffic and transport, consisting of policy makers, practitioners and scientists. Isabel Wilmink, member of TrafficQuest chaired the session and introduced the five interesting speakers and presentations on the various topics on the program. It was a very interesting and succesful afternoon. The presentations can be viewed and downloaded in the remainder of the text.
