In Search of the Value of Time: From South Africa to India

Abstract

The route choice behavior of toll route users and their perceived values of time (VOTs), which determine their choice of route, are critical in modeling the toll income stream of a proposed toll road. This is also fundamental in assessing the financial risks of the financiers of the toll road investment. Internationally, the most acceptable approach is to use individual choice or discrete choice models calibrated on the potential users’ actual route choice or discrete choice models calibrated on the potential users’ actual route choice behavior (revealed preference – RP) as well as their intended behavior (stated preference – SP). The VOT is subsequently used in network transport models such as EMME/2 and SATURN so that these models reflect the correct distribution of trips amongst alternative routes for each Origin-Destination (O-D) pair of the trip matrix. VOTs are therefore critical parameters in the trip assignment process and it is important that VOTs are estimated accurately. This chapter describes three value of time studies that were conducted for the purpose of two toll road studies in South Africa and one in India.
