Rural Transit Need and Demand Workshop Project B-3 (1995) ◦ Methods for forecasting Demand based on data from 39 selected counties ◦ Workbook and spreadsheet (in 1-2-3) ◦ Methods applied by states and agencies Mixed reviews Project B-36 ◦ Methods for both Need and Demand ◦ Used national databases ◦ Considered new travel markets 3
4
Rural Transit Need and Demand Workshop Markets have changed FTA requirement for Public Transportation-Human Service Coordination Plan ◦ Plans will be more useful if related to measures of unmet need and served demand Internet provides easy access to data not readily available in 1995 Good forecasts provide support for funding from local governments 4
5
Rural Transit Need and Demand Workshop Need = number of persons likely to require service Demand = Use of service at given level of quality and cost Both are required; need may be more important to build support It may be more useful to forecast demand related to changes from a base condition 5
6
Rural Transit Need and Demand Workshop Demographic data – American Community Survey (and PUMS) ◦ Only source for disability data ◦ 3-Year data available for areas having a population of 20,000 or more ◦ 5-Year data for areas of all size available at the tract level 6
7
Rural Transit Need and Demand Workshop National Household Travel Survey ◦ Valid data only for large geographic areas Rural National Transit Database (NTD) ◦ Service areas not clearly identified ◦ Patronage by market not specified ◦ Some questions about data quality ◦ General public services only 7

15
Rural Transit Need and Demand Workshop Basic data required to estimate need and demand ◦ Service characteristics Service area population Service area (square miles) Annual vehicle-miles Annual vehicle-hours Number of one-way trips served (boardings) ◦ Community Characteristics Area of each county in service area (square miles) College/University enrollment List of social service agencies providing transportation 15
16
Rural Transit Need and Demand Workshop Populations in need Mobility Gap ◦ Number of trips needed 16
17
Rural Transit Need and Demand Workshop General purpose rural – mostly demand response Program trips – tied to human service programs Small city fixed route – in small communities, under 50,000 population* Commuters – rural area to urban center* * New topic not addressed in project B-3 17

21
Rural Transit Need and Demand Workshop Need relates to transportation that is required so that individuals can fulfill life needs and participate in society. Need is independent of the quality of available transportation ◦ Need is measured in two ways: people and trips Demand is the number of trips that will be made using a transportation service offered at a given price and level of service. ◦ Demand is measured in trips 21
22
Rural Transit Need and Demand Workshop Mobility Gap - The difference between the number of trips made by persons with access to a personal vehicle and those who lack such access ◦ Represents the full unmet trip need relative to those with relatively unfettered mobility ◦ Measured in trips per day ◦ Serving all of the unmet need is unrealistic. This measure can be used to estimate the proportion of unmet need that is served or to set goals based on proportion served 22
23
Rural Transit Need and Demand Workshop Program trips – trips that would not be made but for the existence of a specific social service program or activity ◦ Trip time and destination established by agency Non-program trips – akin to general public transportation but includes trips made using a service limited to specific groups (e.g. persons age 60 or over) ◦ Trip time and destination chosen by traveler 23
24
Rural Transit Need and Demand Workshop In this methodology a trip is a one-way trip from point A to point B For fixed-route and non-program trips, a “trip” is as defined for the National Transit Database i.e. a “boarding” For program or sponsored trips, a “trip” is a linked trip from original origin to ultimate destination 24
25
Rural Transit Need and Demand Workshop Rural – a county which has a population density less than 1,000 persons per square mile Urbanized Area – a central place and adjacent territory with population density ≥ 1,000 persons per square mile and total population of at least 50,000 25
26
Rural Transit Need and Demand Workshop Urban Cluster – A densely settled area with a population between 2,500 and 50,000 ◦ Defined by U.S. Census Urban Center – the central place of an urbanized area ◦ As used in the demand forecasting methodology and Workbook 26

Rural Transit Need and Demand Workshop Program trips – trips that would not be made but for the existence of a specific social service program or activity ◦ Trip time and destination established by agency Non-program trips – akin to general public but includes trips made using a service limited to specific groups (e.g. persons age 60 or over) ◦ Trip time and destination chosen by traveler 50
51
Rural Transit Need and Demand Workshop Preferred Sources of Data (in decreasing order) ◦ Your System ◦ Systems Operating in Similar Rural Settings in Your State ◦ Systems Operating in Similar Rural Settings Elsewhere 51
52
Rural Transit Need and Demand Workshop Operating environment ◦ Size of service area (population; square miles) ◦ Presence of college or university ◦ Funding sources Degree of coordination ◦ Social service programs in operation ◦ Agency provided client transportation 52
53
Rural Transit Need and Demand Workshop Your state transit agency or transportation agency State transit association ◦ Your state ◦ Neighboring states National Rural Transit Database Call other agencies For larger systems: Integrated National Transit Database Analysis System 53
54
Rural Transit Need and Demand Workshop Information Needed (for identified peer systems) ◦ Population of the area served ◦ Size in square miles of the area served ◦ Presence of major generator (College, Employer, etc.) ◦ Annual vehicle-miles and/or vehicle-hours of service provided ◦ Nature of the operation (e.g. fixed-route, route- deviation, demand-response) ◦ Number of one-way trips served (per month, per year) ◦ Degree of coordination with other carriers 54
