Agenda• Why focus on demographics• Data views• Processes & Methods Overview• Samples

Why focus on demographics• Business focus on if or where to open stores• Product inventories• Demographics analytics are a foundation for:

– Elected officials win/loss– Projects approved/stopped– Funding increases approved/stopped– Service/ridership performance– Services improvements– Route changes– Route schedules– Capturing additional market-share

Big Data Analytics

• Demographic datasets– Census

• Ridership studies• Surveys• Trip data• Machine logic to analyze video feeds• Store and analyze from geodatabase

Key data views or datasets

Assets• Asset Management Overlay• Service profiles

– Modes– Routes– Schedules

• Maintenance Yards• Evacuation Routes• Service impedances

– Incidents– Construction– Weather impacts

Services/Ridership• Ridership profile by route• New service by user group• Service changes by user

group• Demographics

– Transit dependency– User groups by route– Ridership peak by route/day– Mobility requirements– Walkability

3D Demographics Analysis• GeoDB design &

integration• Population density

growth• Transportation

model output aligned to TAZ’s

• Route Service Alternatives

• Enables stakeholders to visualize from one common dataset

• More readily understand constraints and interact with dynamic view of data

3D Demographics Analysis

• GeoDB design & integration

• Collected building footprints

• Overlay with census and ridership data

• Overlay with route and service plans to optimize service/market capture

• Analyze over time once service begins

• Colors depicting potential customer base

Route Demographics• GeoDB design &

integration• Custom developed

Geoprocess tools• Station catchments• Demographics data on

service use• Route analysis on

preferred service• 3D catchments

prepared for community workshop

• 3D ArcScene model files prepared for meeting

3D Metro Ridership• GeoDB design &

integration• Custom

geoprocess tools to evaluate and display selected ridership characteristics for service planners

• Route and service analytics prove justification for service changes/ enhancements

• Public and elected officials can see the same views and common data analysis

Transit Service Time-slider• GeoDB design &

integration• Custom developed

GeoTools (3 Modules – 4 tools)

• Tool evaluates and provides Conflict Alerts service planners or managers/operations, external agencies to alert on construction impacts, route closures, incidents or requested permits against transit service impacts from demographics overlay

• Helps provide viable route alternatives and potential ridership impacts
