Socio-economic Attributes And Impacts Of Travel Reliability: A Stated Preference Approach


This report examines the behavioral reactions to the impact of changes in the probability of a non-recurrent incident and how this affects the expected costs of a commute trip. The basic approach combines the estimation of a travel demand model with a supply side model of a congested highway. Various socio-economic variables, including a detailed classification of occupational groupings, are also examined. The tasks are accomplished through a theoretical model of scheduling choice in the face of uncertain travel times, and through a survey of commuters in the Los Angeles region.
