Slapa, R. (1990) Car Travel Time Variability on Links of Two Urban Routes in Berlin (West): Methodology and Surveys. Working Paper. Institute of Transport Studies, University of Leeds , Leeds, UK.
This report describes the surveys conducted, and the methods employed, for a study of travel times on two routes, each of five links, in Berlin. The surveys were conducted in order to study the level of variability of travel time, to identify possible causes of variability, and to test the reliability with which vehicles equipped with LISB route guidance equipment could estimate the mean and distribution of route and link travel times. Travel times were recorded by registration number matching, from LISB records of equipped vehicles passing, and fm manual and LISB-based records from two LISB-equipped survey vehicles. Potential explanatory variables recorded included flow, composition, turning movements, parking, and two congestion indicators. The study formed part of a larger project on fundamental aspects of dynamic route guidance systems.
