Abstract

In this report, all traffic movements are divided into two basic types. External trips. Trips in this category have this origin or destination within the study area and pass through only one interview station route to their destination. Through-trips. Trips in this category had neither origin nor destination within the study area and pass through two interview stations route to their destination. Traffic flow charts indicating the internal dispersion of traffic by tract of origin or destination are included in this report along with a series of desire line charts showing desired routes of travel in straight lines between interview stations and tracts within the city. These charts along with the accompanying tables illustrate the movement of traffic through Grinnell as well as desired routes of travel. It is not within the scope of this report to make recommendations concerning the revision or construction of routes, but rather to organize and present the findings of the survey in a manner which will be helpful to local officials in determining traffic needs. It is hoped that this report will point the way toward the solution of any existing traffic problems and thereby help provide adequate and efficient transportation facilities for the people of Grinnell.
