  1. INDOT Detection Test Facility Jim Sturdevant, P.E.Operations SupportIndiana Department of TransportationIndianapolis, IN 317 232 5073 JSTURDEVANT@indot.state.in.us

  2. Outline • Objectives • Background on West Lafayette Site • New Site in Noblesville • Upcoming Testing in 2004

  3. Objectives • Develop an objective performance specification and evaluation procedures for the INDOT approved products list. • Video • Count Detectors • Other emerging technologies • Provide a facility for quantitatively evaluating new control features.

  4. West Lafayette Site • West Lafayette, IN • Stadium & US 231

  5. Data Collection • West Lafayette, IN • Urban • Currently operational, to be reconfigured similar to Noblesville in 2004 • Noblesville, IN (Under construction) • Suburban • Reconstruction Summer 2003.

  6. Dual Cabinets

  7. Signal Cabinet

  8. Instrumentation Cabinet • Fiber Connection • Video Modems • IP Based I/O Monitoring

  9. Stadium & Northwestern Fiber Optic Cable Connection

  10. Indoor Facility

  11. Indoor End of Equipment

  12. Indoor Interface: Signal Status & Cabinet

  13. Text Overlay • Phase Indication • ILD Status • VID1 Status • VID2 Status NA,NB NL

  14. Noblesville Data Collection Site • Piggybacking on new INDOT reconstruction of SR 37 an SR 38 that will be used as INDOT test site • Build upon success of West Lafayette instrumented intersection, and improve on some of those limitations • Pavement Mill and Fill • 2 Cabinets • DSL Service • Remote IP PTZ Camera • 60 Detection Channels on 4 BIUs in Signal Cabinet • 77 inductive loops • 34 microloops • Additional 12 Autoscope video detection units (3 per approach) • Additional video units by other vendors • 60’ Mast Arms (Cameras at ~60, 36, and Pole)

  15. Sensors • Micro Loops • Peek Video Detection • Autoscope Video Detection • Iteris Video Detection • Preformed Loops

  16. Site Location

  17. N Noblesville Plan View: Detection/Phasing

  18. N Noblesville Plan View: Example Video Detection

  19. Example Noblesville Camera Views: Note: new installation will have improved orientation/aspect/height

  20. SE Corner, Existing Cabinet

  21. Noblesville Data Acquisition • Use TS 2 Type 1 Cabinet • But will use 24 Volt signals interfaced to a Solo Pro • Solo Pro will collect time stamped state changes on up to 8 digital inputs and display status on video

  22. Example Solo Pro • Long detection zone • Short detection zones • For Northbound • (2) inputs of Phase 2 & 5 Green Status • (4) inputs for detectors • (2 spare)

  23. MiniHub Data Collection • 8 Discrete Inputs • Similar capabilities (logging/video overlay) as West Lafayette site, but with equipment familiar to techs

  24. Supplemental Data Collection • Will also use Opto 22 data acquisition • Allow synchronized data collection time stamps for 128 I/O points • Ethernet Access • Ftp transfer of time stamped logs • Embed simple logic for preprocessing data

  25. Example Solo Pro Data

  26. Data Collection • Solo Pro will be use for data collection purposes since it provides a convenient way to log time stamped events (video overlay an file) using equipment INDOT technicians/engineers are familiar with. • However, other loop and video detection units will be installed….outputs from those units will be connected to spare (6) Solo Pro Inputs

  27. Auxilary Cabinet Patch Panels

  28. Example Solo Pro Video

  29. Upcoming Testing • Quantifying loop and video detection accuracy • False Calls • Missed Calls • Quantifying loop and video counting accuracy • Evaluating new algorithms
