Zach Van Gemert• Born and Raised in Denver, CO.• Education in Land Use/GIS• Employed at RTD for 11+ years
– Systems support for Call-n-Ride, GIS, INIT, Ridecheck Plus, Trapeze
Regional Transportation District ( )• Service Area
– Population: 2.8 million– Area: 2,340 square miles– 40 municipalities, 6 counties plus 2 city/county jurisdictions
• Services– Fixed routes: 133– Bus Stops: 9,504– Park-n-Rides: 77 with 31,049 parking spaces– Special Services
• Access-a-Ride• BroncosRide• BuffRide• Call-n-Ride• RockiesRide
• Ridership– 2012: 328,109 average weekday boardings
• Vehicles– Bus: 998– Light Rail: 172
Federal Transit Administration (FTA)• States “Transit providers shall prepare demographic and service profile maps and
charts after each decennial census and prior to proposed service reductions or eliminations.”
• Title VI Program Plan: must be submitted to FTA every three years and must be approved by board of directors or appropriate governing entity prior to submission to FTA.
• Transit providers that have implemented or will implement a New Start, Small Start, or other new fixed guideway capital project shall conduct a service and fare equity analysis.
• Require maps displaying transit base data, demographic profile data and transit facilities
• Demographics– Maps and Charts– Low Income Areas
• Aerial Photo (Land Use)• Minority Population Density• Population + Employment Density
– Minority Population Area• Aerial Photo (Land Use)• Low Income Household Density• Population + Employment Density
– Limited English Proficiency (LEP)• Fare Policy• Service Changes• Service Standards
– Headways– On-time Performance– Service Availability– Transit Amenities– Vehicle Assignments
Title VI Program Plan
Base Spatial Data
• District Boundary• Route Lines• Transit Facilities
– Administrative– Maintenance– Park-n-Rides– Rail Stations– Shelters– Transfer Stations
• Other– Business Districts– Hospitals– Schools
Title VI Program Plan cont.
Title VI Program Plan cont.
– Low Income Areas• Aerial Photo (Land Use)• Minority Population Density• Population + Employment Density
– Minority Population Areas• Aerial Photo (Land Use)• Low Income Household Density• Population + Employment Density
Demographics
Shelters• Areas of Dense Low Income
or Minority Populations– Equitable distribution of
stop shelters
Title VI Program Plan cont.
Census Data• Census.gov
– American FactFinder• factfinder2.census.gov
• Low Income Households Density– FTA “any group of households whose
income is <=150% of the household sizepoverty guidelines for the average householdsize of that census tract”
– Calculations• AVERAGE_HH_SIZE: TOTAL_POP / HOUSEHOLDS• HH_LESS_25: [HH_LESS_10] + [HH_10_15] + [HH_15_25]• HH_LESS_35: [HH_LESS_25] + [HH_25_35]• HH_LESS_50: [HH_LESS_35] + [HH_35_50]• HH_LESS_75: [HH_LESS_50] + [HH_50_75]• LOW_INC_HH:
– IF [AVERAGE_HH_SIZE] <= 2 THEN [HH_LESS_25]– IF [AVERAGE_HH_SIZE] > 2 AND <= 4 THEN [HH_LESS_35]– IF [AVERAGE_HH_SIZE] > 4 AND <= 6 THEN [HH_LESS_50]– IF [AVERAGE_HH_SIZE] > 6 THEN [HH_LESS_75]
• LOW_INC_HH_PCT: [LOW_INC_HH] / [HOUSEHOLDS]
• Minority Population Density– Total Population - White Population = Minority Population– Minority Population / Total Population = Minority Population Density
West Corridor• Maps Displaying Each
Service Change– Low Income Households
Density– Minority Population
Density
Demographic Analysis
“Polygon Overlay Tool”
• Spatial Area Ratios– Ratios applied to
demographic fields
Tables• Regional Population Data (RTD Service
Area)– Total Population of Service Area– Minority Population– Minority Population Percentage– Total Households– Low-Income Households– Low-Income Households Percentage
• Affected Census Tracts– Route/Service
• Bus• Call-n-Ride• Light Rail
– Service Change Type• Current Route• Discontinued Service• New Route
– Total Population Affected Tracts– Total Minority Population in Affected
Tracts– Minority Population Percentage– Total Households Affected Tracts– Total Low-Income Households in
Affected Tracts– Low-Income Households Percentage– Spatial Data Type Used
Summary
• Title VI Reporting– Responsibilites– GIS– FTA
