Travel Demand Model - OKI

OKI/MVRPC Travel Demand Model – Version 6.05. Trip GenerationThe final trip generation estimates are produced in Step16. This step calculates trip attractionsfor all trip purposes, as well as trip productions for the purposes not estimated in Step15. Theexception is non-home based trips, which are estimated after mode choice.Several changes were made to the Step16 input, control, and executable files. Many of the tripattraction databases were updated with information from Montgomery, Greene and Miamicounties. All zone-based information was expressed in terms of the new consolidated system.Some changes were introduced to the process of balancing attractions to productions, in order tohave more control over the allocation of attractions between the two regions. The mostsignificant update however was related to the external cordon trips. The 1995 ODOT cordonsurvey was used to re-estimate the external-to-external trip table, as well as the internal-toexternaltrip end equations. A detailed explanation of the survey processing and re-estimationprocess is given in Section 7 of this report. All other updates to the trip generation data and filesare documented in the following subsections.5.1 Taxi and Home-Based School Trip TablesThe taxi and home-based school transit trip tables were renumbered so that they conform to theconsolidated zone system. In the case of split zones, trips were distributed according to theproportion of households in the target (i.e. consolidated) zones.5.2 School-Age Population DataThe database of school-age population (ages 11 to 17) by county was updated to include theMVRPC counties.
