This Users Guide provides methods, transferable parameters, tables, nomographs, etc., for use with manual and computer techniques for urban travel estimation. A companion report, "Travel Estimation Procedures for Quick Response to Urban Policy Issues" was also prepared. The two documents are the results of an investigation of the ability of travel estimation procedures to provide information which can be used to respond quickly to urban policy issues. This document provides manual techniques and appropriate tables and graphs in the areas of: trip generation, trip distribution, mode choice, auto occupancy, time-of-day distribution, traffic assignment, capacity analysis and development density/highway spacing relationships. Application of the material to three scenarios (site impact, corridor analysis and density/highway spacing) is also included. There are numerous problem areas where application of the manual methods provided will prove advantageous as compared to the application of computer procedures. The transferable parameters allow quick response compared to the time required to collect local information, and may be used by computer methods as "default" values where more appropriate local information may not be available. The parameters are also used in the manual methods described. /Author/
