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.

of our staff.The Report outlines the procedure to be followed in application of the methods developed in this research study for determining traffic patterns for the simplified procedure for major thoroughfare planning. The Manual is provided to encourage the implementation of the procedure.The Report is presented for acceptance as fulfilling the objectives of Part V of the Study and will be forwarded for review, comment and similar acceptance by ISHC and FHWA.
