APPLICATIONS OF TRAFFIC MODELS: SUMMARY REPORTS FOR IMPACT ANALYSES AND COMPARISON OF DELAY AMONGST MODELS IMPROVING THE KNOWLEDGE BASE AND TOOLS FOR TRANSPORTATION

As a result of discussions with users, reinforced by the experience of the authors, two priorities were established for this phase of the project: (1) developing a systematic way of creating summary tables from the collection of intersection analyses typically found in a traffic impact evaluation, and (2) providing some understanding of how delay estimates generated by various traffic models interrelate. To meet the first priority, a spreadsheet template and an associated program (transparent to the user) was developed which allows the user to: (1) define case names in an orderly manner, (2) use a spreadsheet macro to load HCM intersection results into the template, and (3) use other macros to print common summary tables of the results, highlighting significant changes in the v/c ratios. To meet the second priority, two real-world arterials totalling 17 intersections were analyzed by three different traffic models (HCM, TRANYT7F, PASSER).
