Research Report 193 Valuation of travel time savings – market research

Published: | Category: Transport demand management , Research programme , Research & reports | Audience: General

This project involved market research among motorists in New Zealand to establish unit behavioural values of travel time savings under a range of conditions, for application in the evaluation of transport projects.

Interviews involved a series of 'stated choice' games, in which respondents chose between a recent (reference) trip as car driver and two alternative trips, which differed in terms of various trip attributes (total travel time, degree of congestion, uncertainty of arrival time, fuel costs and toll charges).

A series of multinomial logit models was estimated to identify the value of each trip attribute. Unit values of travel time savings for car drivers in a range of conditions were derived, in particular according to trip length and purpose, degree of congestion, and uncertainty of arrival time.

The values derived were compared against those currently used for project evaluation purposes and recommendations were made.
