ATTACHMENT A: PROJECT SCOPE AND TIMELINEREQUEST FOR QUALIFICATIONSTO PROVIDE TRAVEL MODEL DATA ASSISTANCEDescription:The scope of work includes several tasks relating to the two surveys and some associated projects.Task 1: Initial Survey AnalysisPart A: Basic data logic checks, including verification that travel days making one transit trip made onlyone transit trip, zero-worker households that made work-related trips, if travel times make sense, andother checks.Part B: Compare the household survey expanded dataset to the Census 2010 and Census ACS (latest 5year ACS dataset available at time of Notice to Proceed (NTP)). Adjust weighting as necessary to match2010 socioeconomic conditions.Part C: Check the transit survey weighting and expansion. In the transit survey weighting and expansion,the two smaller agencies (TANK and CTC) were computed by the consultant that collected the data. Theweighting and expansion for the largest transit agency, Metro, was computed by OKI staff.Part D: Merge the household survey and transit survey datasets, with weights and expansion factors andadjust as necessary. Also, assign trip purpose, tour id, and tour type based on the survey responses.Finally, a discussion and recommendation of if- and how- to utilize the additional travel days collected inthe household survey.This task's deliverable will include a technical memorandum describing: The checks that were performed, any data imputation performed as a result of the checks The initial and final comparisons of the weighting to the Census data and discussion of theadjustments made to the weighting and expansion factors Discussion and recommendation on the use of the additional travel days of household surveydata, including supporting documentationThe final merged travel survey data table will be delivered to OKI as DBF files.Task 2: Development of Model Estimation Data FilesThe second task is the development of data files that can be used for trip rate estimation and calibration ofvarious steps. Because OKI is in a transition period, deliverable files will include files for both trip-basedmodeling and tour-based modeling.Part A: Trip-based modeling - This includes files to be used for the estimation and calibration of the tripgeneration, trip distribution, and mode choice models. The selected consultant will deliver the followingdata files:Estimated trip production and attraction totals by purpose, district, and county, and wherepossible, by area type, number of autos, workers, and people in household.An estimated matrix of total person trips by, district, and county.Estimated tables of trips by mode and origin county (and, if possible, destination county). Modein this case will include 11 modes used in the model (Local bus walk, park-n-ride, kiss-n-ride,14
Express bus walk, park-n-ride, kiss-n-ride, drive alone, 2 person shared-ride, 3+ person sharedride,walk, and bicycle).Tables suitable for mode choice estimation software. 'Suitable' in this case refers to the dataincluded in the table, not necessarily the file format of the table.Part B: Tour-based modeling - This includes files to be used for the estimation and calibration of autoownership, daily activity pattern, free parking eligibility, transit pass eligibility, and destination-timemodechoice. The selected consultant will deliver the following data files:A comprehensive table that can be used to estimate household-level choices, such as autoownership.A comprehensive table(s) that can be used to estimate person-level choices, such as dailyactivity pattern, free parking eligibility, transit pass eligibility, destination-time-mode choice,non-mandatory tours, joint tours.A comprehensive table that can be used to estimate tour-level decisions, including destination,time (beginning and ending by 15-minute intervals), primary mode, the identification ofsubtours, number of stops, stop locations, and parking location (in the CBD areas of Cincinnati,Covington and Newport only).Tables of estimated auto ownership, including estimated number of autos per household (HH) bycounty, household size (person per HH), number of workers per HH, number of adults per HH,and number of adults and school-driving-age children per HH.Tables of estimated number of people with each mandatory daily activity pattern by county, autoownership, household size, and number of workers.Tables of estimated persons receiving free parking by origin county and income level.Tables of estimated persons receiving a free transit pass and those having a transit pass by origincounty and income level.The tables above should, wherever possible, show a comparison between Census, ACS, and HHTS data.Another deliverable of this task is a comprehensive technical memorandum detailing the processesundertaken to estimate the summary tables and estimated matrices, including the data used in theestimation process.Product SpecificationsAll project deliverables provided to OKI under this study shall be submitted with the following conditionsand requirements:1. All files from Microsoft Office products will be delivered in their native format, provided thatthey can be opened in Office 2007.2. Cube Voyager Matrices will be able to be opened with Cube 6.3. Database files will be DBF version 4.4. Scripts used as part of the project (e.g. SQL code in FoxPro, Cube Voyager Scripts) shall bedelivered to OKI at the conclusion of the project5. Executable programs created as part of the project will be open source, and delivered to OKIboth as executable binaries and as source code.Project Schedule:The successful candidate firm will agree to complete the work prior to January 31, 2013.15
