Transit Scheduling/Routing Data Applications

  1. 1. Using Data to Design and Manage TriMet’s Route Network Portland State University Center for Transportation Studies Transportation Seminar Series November 2, 2012
  2. 2. Stop Records  Date  Line, Direction  Bus/Trip  Operator  Stop  Latitude/Longitude  Arrive/Leave Time Dwell Time Scheduled Leave Time Passenger Ons/Offs
  3. 3. A HEAP of data….
  4. 4. …needs to be structured for MANAGEMENT decisions
  5. 5. When is a bus or train too crowded? How do schedules account for variable traffic? When and where should buses run more often? How can street designs work better for transit? Some Questions…
  6. 6. Service Standards Systematic, comprehensive, predictable method to design, evaluate and adjust service Balance ridership, cost, community needs to improve usefulness of our service to the public
  7. 7. Service Standards Network Design  Route structure and layout  Policy headways  Span of service  Stop spacing
  8. 8. Service Standards Network Design  Route structure and layout  Policy headways & span of service  Stop spacing Service Priorities  Passenger capacity  Service reliability  Frequency and span of service
