Presentation Transcript

  1. MAST Effectiveness Study GDOT Fast Forward Billy Bachman, GeoStats Marwan Abboud, Arcadis

  2. Metro-Atlanta Signal Timing Project • Effectiveness of overall program • Effectiveness of timing on each corridor • Before/After travel time and delay studies • MOE: Delay, Emissions, Fuel, $ GPS-equipped probe vehicles Exploring alternative solution: GPS equipped population sample

  3. Speed Profile – Bells Ferry Rd. - All Time Periods

  4. GPS Population Sample – Panel or VII Massive amounts of sec-by-sec personal travel data for behavior analysis AND system performance

  5. Challenges and Opportunities • Privacy protection of instrumented personal vehicles • Data reduction for analyzing and reporting system performance • Spatial data mining • Spatial data integration / fusion

  6. GPS Probe Vehicles Detailed performance data by route/link/intersection

  7. Future Research Notes • Operational data (GPS, ITS, Mobile phones, etc.) reduction to different spatial scales and network representations • Data imputation / cleaning to support various transportation business functions • Data mining of operational data to extract / estimate activity patterns • Visualization of spatial / temporal data • Advance statistical understanding and communication of variance / error and other measures • Data collection logistics … does sampling strategy support multiple uses • Design of transportation networks to support operations information and to support cross-discipline integration
