While the FTA does not proscribe the parameters or procedures that should be used or <br />approve the actual forecasting procedures, they have guidelines that should be followed. Two key focus areas are <br />(1) how reasonably the models explain transit user decisions as demonstrated by their reproduction of recently <br />collected on-board survey data and transit ridership counts, and (2) the reasonability of mode choice model <br />coefficients and constants. <br />The Cordoba team developed a transit ridership forecasting procedure for the Conceptual Engineering task that was <br />consistent with FTA guidelines. "Data driven" techniques were used based on data from OCTA`s recent transit on- <br />board survey coupled with incremental logit model procedures. The data driven techniques are similar to innovative <br />techniques that the FTA presented in a 2009 New and Small Starts workshop in Phoenix. This approach has <br />received conditional approval from FTA. <br />The proposed approach for the Pre-Preliminary Engineering Analysis is to confirm and, if necessary, adjust the <br />transit ridership forecasting procedure through formal coordination with FTA staff, update transit networks and <br />socioeconomic forecasts for the project opening year, and produce refined transit ridership forecasts. <br />A key statistic for FTA New Starts / Small Starts is User Benefits, expressed as travel time savings that accrue from a <br />project. While the travel models are the basis for estimating travel time savings, FTA recognizes that most <br />conventional travel models do not capture three categories of attributes providing additional User Benefits for fixed <br />guideway alternatives: 1) Guideway-like characteristics, 2) Span of service, and 3) Passenger amenities. FTA allows <br />projects to include credits for fixed guideway alternatives if the sponsor can demonstrate the project possesses the <br />attributes identified above. A maximum benefit of 15 minutes of travel time savings is possible per new rider. The <br />Cordoba Team will work closely with FTA to ensure that the maximum benefits can be applied to the project. <br />Cambridge Systematics has considerable experience working with FTA to develop ridership forecasts for rail transit <br />projects and for Section 5309 grant applications; they have prepared the 2035 ridership forecasts for the Santa Ana <br />and Garden Grove Fixed Guideway Corridor Study. They will lead the development of the ridership forecasts for Pre- <br />Preliminary Engineering Analysis, with support and input from JPC. Jennifer John of John Parker Consulting (JPC) <br />in Portland prepared the Ridership Forecasts and associated submittal materials for the successful Portland <br />Streetcar Loop Small Starts application. She will oversee the work on this task and will assist SOJ with coordination <br />of the analysis and submittal to FTA. She will be fully supported by CSI, who will work with her and the rest of the <br />project team to insure the most favorable outcome possible for the project in terms of the Cost Effectiveness rating. <br />This may require modifications to the model procedures as well as additional data collection. <br />D. Kurth, S. Myung, J. John I' One <br />tronic and 12 hard copies of the draft and the final <br />forecasts <br />Task 8 - FTA Summit Analysis <br />Cambridge Systematics (CSI) has developed forecasting procedures that are compatible with OCTAM and that will <br />allow for the output of appropriate model components to be used with the FTA Summit software tool for the Santa <br />Ana - Garden Grove Fixed Guideway project. This software tool will be used to assist with analysis of the <br />alternatives under consideration for this project. JPC will analyze the model and Summit outputs for the alternatives <br />and will work with the project team and stakeholders as needed to determine what, if any, changes should be made <br />in order to better position the alternatives from both a project standpoint in terms of providing the best possible <br />Section Three - Work Plan 34 <br />25D-38 <br />
