Resum
This paper shows that the precision of a freeway travel-time information system, in a real-time context, is not related solely to the accuracy of the measurement. Immediacy in reporting the information and forecasting capabilities play a role. Therefore, focusing only on the accuracy of the travel-time measurement is a myopic approach, which can lead to counterintuitive results. Specifically, it is claimed that, using travel times estimated with the traditional spot-speed midpoint algorithm, the...
