THE SUBJECTIVE VALUE OF THE TIME SPENT IN TRAVEL

Abstract Value of the time spent in travel is a surrogate measure of the comfort, convenience, and reliability of the travel experience as a function of travel model, purpose, and time period and the environmental conditions affecting the trip. Value of time spent in travel is consequently an important element in spatial interaction and transportation analysis. Subjective value of the time spent in travel was measured using a psychological scaling technique, magnitude estimation. Data were obtained from 84 Chicago residents. Completion of the questionaire required each participant to provide judgements of the relative value on 115 different trips in comparison to one standard trip (e.g. a 20 min work trip by automobile). Information gained in this way illustrates the variability that can occur in values of time due to various trip characteristics.
