A Simplified Procedure for Major Thoroughfare Planning in Small Urban Areas

Abstract

INFORMATIVE ABSTRACTThe purpose of the research project was to develop a simplified procedvire for major thoroughfare planning in small urban areas. Previously developed corridor growth fuctor models for developing future estimates of intem€LL traffic in small urtan areas were tested, modified and refined using Lafayette, Indiana data.Regression models to provide data ususilly obtained by use of external cordon surveys were developed. External survey reports from thirty-six cities in fourteen states, remging in population from ten thousand to ninety thousand, provided the majority of the data utilized. Alternate procedures for providing the external svirvey information, based on use of historical data from the subject city, were also developed.The completed procedure provides forecasted traffic volumes within the accuracy necessary for major thoroughfare planning in small urban areas at Jones, Grecco 2 lower cost and with a level of sophistication that will permit application by personnel usually available in small coinm\inities The feasibility of the complete procedure for providing the required traffic volmne for major thoroughfare planning in small urbaji areas weis demonstrated in Columbus, Indiana.

Procedure Manual for Determining Traffic Patterns for a Simplified Planning Procedure for Major Thoroughfare Planning in Small Urban Areas : Interim Report

“…The growth factors computed are applied to the base year corridor traffic volumes and then compared to the existing volumes. (3) . The traffic volumes existing on each major thoroughfare will be divided into two components, one representing the external traffic and one representing the internal traffic.…”
