1. INDOT Detection Test Facility Jim Sturdevant, P.E. Operations Support Indiana Department of Transportation Indianapolis, 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

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. Noblesville Plan View: Detection/Phasing N

18. Noblesville Plan View: Example Video Detection N

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

30. Example Solo Pro Video

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