1.6.2 Data Gathering. Collect and analyze data required for the development of the San Marcos model to include but not be limited to the following: a) Documentation, databases, and modeling components required to operate and assess the current CAMPO travel forecasting model. b) Detailed geographic information systems data on land use, population, employment, and roadways. c) Traffic counts at approximately 50 locations inside the City of San Marcos and on its periphery (some of which may be included in the CAMPO model databases). d) Data on Southwest Texas State University ("SWTSU") faculty, student, and staff residence locations. e) Transit rider ship data by route and period of the day for all services operating in the San Marcos area. The Consultant will provide to the City a technical memorandum describing the data listed above and additional processing required to use it in the City's model. Consultant will distill collected data and the technical memorandum onto a CDROM for later use and archival purposes. 1.6.3 Adjust Auto Ownership Model. Review the CAMPO auto ownership model, and compare it against data available for San Marcos. The Consultant will document changes in the model coefficients and parameters, as well as necessary changes to the auto ownership model itself. The Consultant will prepare and deliver to the City in hard-copy, Microsoft Word, and Adobe.pdfformats a technical memorandum describing the proposed changes to the CAMPO auto ownership model. Consultant will make all changes in the TransCAD application used for estimating auto ownership at the zonal level. 1.6.4 Home-Based University Model. Develop a travel model for university students that is capable of handling trips to SWTSU and the University of Texas. The Consultant will evaluate the university trip purposes in the CAMPO model and explore ways to adjust them for SWTSU specifically, using locally available data. The model developed by the Consultant for SWTSU will differ from a traditional gravity model in that the attractions (student enrollment) are fixed and the Productions (residence locations) are allowed to vary. The Consultant will also include an attraction model, which will relate the attractions to the enrollment and to the percent of students living on campus. The latter will vary considerably between SWTSU and commuters to the University of Texas at Austin. If sufficient data are available from both institutions, the Consultant will also segment the students by full-time and part-time students. The Consultant will also prepare and deliver to the City a technical memorandum in hard-copy, Mircrosoft Word and Adobe. pdf formats describing the home-based university trip modeling process proposed for the City model, to include use of information from the current CAMPO model. 1.6.5 Calibrate Mode Choice Model. Adapt the nested log it model used in the CAMPO model for use in the City model to include a thorough review of the CAMPO mode choice Transportation Masterplan K.wpd 5
