locations and general operating characteristics and constraints will also be documented to reflect the modifications made to the Reduced Set of Alternatives as a consequence of the screening analysis/approval process. [Note: identification of major underground and overhead utilities will be initiated soon after the screening step, during Task 6.2 to avoid potential problems later on that may be associated with some alternatives due to the need to relocate major utilities.] Deliverable(s) - Initial Alternatives Screening Report TASK 5.0 TRAVEL DEMAND FORECASTING This task involves the forecasting of travel demand for the alternatives. A methodology and set of forecasting results will be developed to a sufficient level of completion to meet EIS/EIR requirements. Using OCTA's OCTAM forecasting tool as the starting point, the Cordoba team will develop a methodology to develop travel demand and ridership forecasts to support the definition and evaluation of alternatives, and to support the selection of a Locally Preferred Alternatives. In coordination with the City of Santa Ana and OCTA, the Cordoba team will prepare the model runs and performance measures for each of the Corridor -wide Alternatives recommended. Deliverable(s) - Proposed Travel Demand Model Methodology Task 5.1 Ridership Estimates & Performance Measures OCTA's OCTAM model will be the basis for the travel demand and ridership forecasting for this project. OCTA is wrapping up model validation on a new 2005 base year model, which we anticipate will be available for this project. We recognize the considerable attention will be paid to the ridership forecasting for this project. The modeling approach and results will require concurrence from the City, OCTA and FTA. The OCTA Board has indicated that the demonstrated reasonableness of the ridership forecasting for the fixed guideway projects is critical to them. The Cordoba Team includes Cambridge Systematics, nationally recognized experts in travel demand modeling and FTA New Starts forecasts. Working together with staff from Santa Ana and OCTA, we will be responsible for implementing a clear step-by-step process to successfully navigate both the FTA travel demand forecasting process as well as OCTA's Go Local program. Working with OCTAM, the Cordoba team will test and as appropriate adjust the model using existing calibration parameters to match ridership statistics provided by OCTA as closely as possible, given the capabilities of the model. The resulting adjusted model will be documented in a Modeling Methodology Report. Following calibration of the model, the Cordoba team will: ■ Review traffic analysis zones and split as required ■ Review study area roadway and transit networks against observed and planned conditions ■ Develop and validate an updated (2009) socio economic dataset as the basis for an Existing (2009) forecasts 121 Page
