Methods to Measure & Monitor Pedestrian Travel

  1. 1. Methods to Measure & Monitor Pedestrian Travel Shawn Turner, P.E. Texas A&M Transportation Institute (TTI) 2018 Texas Pedestrian Safety Forum Austin, Texas, July 12, 2018
  2. 2. Challenges •Less confined to fixed paths •Unpredictable movements •Travel in closely spaced groups •Limited automated equipment
  3. 3. The walk ahead of us… Now Soon Later?
  4. 4. Now Smartphone/tablet counter Clipboard and paper Infrared sensor Video Source: Miovision
  5. 5. Now Bluetooth/WiFi sampling National travel surveys: ACS & NHTS Source: FHWA-SA-17-041 Regional demand model from limited counts Source: NCHRP Report 770
  6. 6. Soon Video analytics (counting) from intersection control systems Source: Iteris PedTrax Video analytics: safety surrogate measures (conflicts, near misses, post-encroachment time)
  7. 7. Later? Hyundai Pedestrian collision warning systems with crowdsourced hot spot maps Passive monitoring of smartphones and other connected devices
  8. 8. Resources: Programs •TxDOT statewide non-motorized count database
  9. 9. Resources: Programs •TxDOT and MPO counter equipment loan programs Infrared counters for pedestrians Tube counters for bikes
  10. 10. Resources: Programs •TxDOT/TTI 402 Program pedestrian counts at high- crash locations (475 signalized intersections!) Houston 2015-16: 75 signalized intersectionsSan Antonio 2015-16: 75 signalized intersectionsDallas-Ft. Worth 2016-17: 100 signalized intersectionsAustin 2016-17: 75 signalized intersectionsHouston 2017-18: 150 signalized intersectionsHouston 2017-18: 34 mid-block locations
