The results of a survey of commuters in austin, texas, are presented. The focus is on commuting habits, particularly changes in route and departure time due to traffic conditions for both the home-to-work and work-to-home commutes. Models of commuters' propensity to switch each of these two choices are developed for both the a.M. And the p.M. Commutes. The models relate switching propensity in each case to four types of factors: geographic and network condition variables, workplace characteristics, individual attributes, and use of information (radio traffic reports). The results provide insights intothe relative importance of each type of factor to switching as wellas differences between the mechanisms underlying a.M. And p.M. Behavior. This paper appears in transportation research record no. 1285, Transportation forecasting 1990.
