Book Description
A research study was conducted to define the social and economic factors affecting intercity travel and to use the resulting relationships with existing traffic prediction tools to predict intercity travel. Data used were the external origin-and-destination surveys of 22 cities. Another source of data was the U.S. census. Trip data from the origination-destination studies were summarized by trip purposes and by increasing time rings from the study area centroids. A stepwise regression analysis computer program was used to determine the relationship between trips and social and economic data. In an alternate analysis procedure, the survey data were utilized to determine the amount and characteristics of intercity trip generation.
