Trip attraction rates study: final report. volumes 1 and 2

The objectives of this study were to: 1) efficiently collect data on current non residential trip attraction rates, non home based trips and non home based (nhb) trip length (duration). 2) Analyze these data in order to develop trip attraction rates by major land use type and development category and make recommendations for the revision of trip attraction relationships used by the tucson area trip generation models. 3) Develop a new nhb trip length distribution for comparison with the current simulation and update the associated model friction factors, if necessary. The study was conducted in two parts, spring 1986 and fall 1986, and encompassed 45 different sites. The sites represented 6 of the 12 employment categories pagptd, the local mpo, used in its trip generation model. Overall, more nhb travel was observed than was predicted in the model. Community shopping centers (csc) and other retail (or) had large increases in their nhb trip rates. Another result was, for some development categories, the observed trip rates were the same as those used in the modelling process. The onr category is especially sensitive to shifts in the economic makeup of the community, it was suggested that the category be further disaggregated. Another possible change to the model system is the elimination of the CBD as a land use/ development category. The results are mixed in attempting to balance the trip production and trip attraction generation models. Home based other (hbo) trips move in the correct direction (towards productions), while home based work (hbw), home based shopping (hbs) and nhb do not (a).
