Probe data from consumer GPS navigation devices for the analysis of controlled intersections

Probe data from consumer GPS navigation devices provides a network-wide and costefficient data source for measuring vehicle movements, whereas experimental studies have been confined to small datasets. Data collection from road-side sensors can provide similar information but is expensive and requires high maintenance expenditures. This paper...

Monitoring travel times in an urban network using video, GPS and Bluetooth

The travel time is an important measure for the quality of traffic. This paper discusses a few methods to measure or estimate the travel time in urban road networks. First of all, it is important to know that urban travel times display a large variation, so that the measurement of a single (average) travel time is not so meaningful. The travel...
