A multivariate analysis of socioeconomic and attitudinal factors predicting commuters’ mode of travel

A random sample of workers was surveyed to assess the influence of different variables thought to play a role in the decision to commute by a particular travel mode. Univariate analyses revealed significant differences between bus riders (n = 125) and car commuters (n=547) on several independent socioeconomic and attitudinal factors, and discriminant analysis correctly classified three types of commuters with 58%−71 % accuracy, using these measures. Solo drivers (n=265) and carpoolers (n=282) differed in their attitudes about carpooling and driving alone, although both groups, as well as bus riders, were favorably disposed to automobile travel. The generally positive attitude of all commuters toward the automobile is discussed in terms of the car’s ability to reduce the information costs involved in traveling.
