Estimation and measurement of link travel times in the ADVANCE project

The current status of the approach being taken in the ADVANCE project to estimate and measure link travel times in the test area is described. A brief review of the representation of link profiles in the Mobile Navigational Assistant (MNA) installed in the test vehicles is presented, followed by a discussion of the estimation of initial static profiles (link travel times) with a network flow model. A discussion of the estimation of link travel times form link flow-occupancy data is given.
