Abstract

The variability of travel times on a given route for a particular journey is known to be an important factor in influencing the choice of mode and route for trips, particularly for those trip types where constraints may exist on arrival time at the destination. Previous work in this area has concentrated on daily variability for journeys by private car. This paper describes some results obtained from a study of travel time reliability for a work trip using two alternative and directly comparable public transport modes, bus and underground rail (metro), in Paris, France. Data were collected to permit the study of the distributions of variations in daily travel times, relationships between measures of variation and congestion, and to compare the characteristics of the two modes. It was found, for instance, that while the bus offered a potentially quicker and more direct service in terms of its free travel time and route location, in practice the metro provided a faster and more reliable service under normal operating conditions. The results of the study confirm and extend earlier work, and some areas for further research are suggested.
