National Traffic Congress 2013

TrafficQuest participated in the National Traffic Engineering and Planning Congress 2013. Just like last year it was held in the Brabanthallen in 's-Hertogenbosch. During the plenary session, the Beter Benutten Programme (the action plan for optimal use of infrastructure) was presented, as well as the booklet “Verandering in reisgedrag” (“Changes in travel behavior”). Subsequently, parallel sessions treated various subjects. Special attention was paid to data and pedestrians this year. TrafficQuest attended the conference and, like last year, presented to papers. The first paper dealt with analogies for traffic management and the second paper discussed traffic predictions using models. It was, again, an interesting congress.

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.
