San Carlos Apache Tribe Transit Study

As Subconsultant to Jacobs Engineering Group, Inc., R. H. Bohannan & Associates conducted key tasks for Phases I and II of the San Carlos Apache Tribe (SCAT) Transit Study. Rob Bohannan was the lead transit planner for the study.

Phase I

For the Current Conditions task, Rob participated in the review of pertinent demographic and socioeconomic characteristics and other existing conditions informationt hat had been inventoried for the San Carlos Long Range Transportation Study completed by Jacobs in October 2009 and adopted in April 2010. Rob evaluated land use patterns, travel data, functional classification of roads, access management, and road and street conditions related to transit operation using data developed or gathered by Jacobs.

Rob also participated in comprehensive field views of potential transit corridors and service areas and identifed neighborhoods, commercial areas, and activity centers that will benefit from increased transit service. Field views encompassed the study area itself, abutting portions of Gila, Graham, and Pinal Counties, and the potential transit corridors between the Study Area and the Phoenix, Tucson, Safford, Whiteriver, and Flagstaff areas germane to the future implementation of regional transit service.

Rob Bohannan participate in the interview of key stakeholders; as well as the identification of service goals and objectives for the SCAT Transit System and other transit goals in the area. Rob assisted in gathering transit and other pertinent socioeconomic and demographic data with stakeholders and analyzed available ridership and other operating data obtained. Rob also reviewed and summarized pertinent studies and plans that had been previously conducted.


SCAT Transit Van Fleet

Rob modeled the current demand for regional transit service to, from, and within the Study Area using the Workbook for Estimating Demand for Rural Passenger Transportation, Transit Cooperative Research Program (TCRP) Report No. 3, published by the Transportation Research Board and sponsored by the Federal Transit Administration. Specific regional transit corridors were tested as directed by Jacobs making use of the findings from the conduct of similar procedures in the Gila County Small Area Transportation Study and the Arizona Eastern Ridership Demand Study**. Rob used available SCAT ridership data to validate these findings, and documented any unmet regional and local public transportation needs of seniors, youths, mobility-limited persons, and others.

For the Future Conditions task, Rob Bohannan participated in an evaluation of the coordination of van pools and other transportation resources among the employees of Indian Health Services, the SCAT Finance Department, other SCAT personnel, the Wellness Center, and other SCAT and non-Tribal employees. Rob assessed the applicability of the “Arizona Rides” concept for coordinating the use of vehicles and other public transportation assets among Tribal and other agencies located within the Study Area including the ALTCS Program, Emergency Medical Transportation, SCAT Social Services, the Diabetes and Wellness Programs, and the General Equivalency Development (GED) Program.

Making use of the TCRP Report 3 Workbook procedure used in the Current Conditions task, Rob estimated the future ridership for each of the time horizons for route and system scenarios developed in consultation with Jacobs, the Technical Advisory Committee, and area

stakeholders. Options for regional service to Globe-Miami, Safford, and Phoenix, and to neighboring Tribal Communities such as the White Mountain Apache Tribe and the Salt River Pima-Maricopa Indian Community were included. Rob participated in examining the synergy of coordinating transit service with service to regional centers of higher education including the San Carlos, Globe, and Safford campuses of Eastern Arizona College, and Gila Pueblo College in Globe. Quantitative ridership estimates were developed based on the levels of service provided, the residential, employment, and activity centers served in each of the candidate route and operating scenarios evaluated, together with time-horizon land-use projections, and socioeconomic and demographic data forecasts obtained from Jacobs.

Phase II

With input from the Jacobs Team, the San Carlos Apache Tribe's Project Manager, and the TAC, Rob Bohannan developed a draft system operating plan that included phased implementation for each of three time horizons. The operating plan include proposed days of operation, hours of service, draft route alignments and candidate stop locations. Management and Maintenance Plans included suggestions for driver training and scheduling and vehicle storage and maintenance. Initial service expansion and enhancement to be implemented in the near-term was recommended, together with phased route extension and expansion of services as time horizons or demographic thresholds are reached.

Rob participated in the development of a capital budget for the draft transit system. Budget elements included the type(s) of vehicles recommended, the passenger capacities of the vehicles, the number of each type required for the fleet, the type of fuel used, and recommended vehicle amenities. The capital costs of the vehicle fleet were estimated. The number of transit stops, bus pull-outs, and other route elements were calculated, together with the capital cost for each.

Rob estimated the costs of operating, maintaining, and administering the recommended transit system, considering the total annual vehicle hours and vehicle miles required to serve the proposed routes that comprise the system. The total rate per hour for operating, maintaining, and administering the system was calculated. These cost estimates included the provision of vehicle storage, maintenance, and fueling facilities.

Working closely with the Tribal transit administrators, Rob developed a candidate fare structure for the system and calculated the annual estimated fare revenues based on the structure. The fare structure included youth, senior, and student discounts, as well as monthly passes, based on best practices of peer agencies. Zone fares based on distance traveled were developed. The anticipated farebox recovery and required Tribal subsidy that would result from the fare structure was presented.
