The effect of inaccurate traffic data for ramp metering: Comparing loop detectors and cameras using information utility

This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...

Datafusie - wat wordt ermee bedoeld en wat heb je eraan?

Heb je het met iemand over verkeersdata, dan valt – naast de zo populaire kreet ‘big data’ – bijna altijd de term datafusie. In veel gevallen is het echter helemaal niet zo duidelijk wat daar nu precies mee wordt bedoeld en waarom het zinvol zou zijn. In deze tutorial daarom een korte introductie. We gaan daarbij vooral in op de kwaliteit van...

The Impact of Loop Detector Distance and Floating Car Data Penetration Rate on Queue Tail Warning

There is a growing interest in the traffic community about the relation between traffic data quality and the efficiency of traffic management. Data collection is expensive and if the same level of traffic performance can be reached with less data or if traffic management becomes more efficient with better data, then that is interesting for a lot...
