Outline

ObjectivesBackground on West Lafayette SiteNew Site in NoblesvilleUpcoming Testing in 2004

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.

West Lafayette Site

West Lafayette, IN Stadium & US 231

Data Collection

West Lafayette, IN Urban Currently operational, to be

reconfigured similar to Noblesville in 2004

Noblesville, IN (Under construction) Suburban Reconstruction Summer 2003.

Noblesville Data Collection Site

Piggybacking on new INDOT reconstruction of SR 37 an SR 38 that will be used as INDOT test siteBuild upon success of West Lafayette instrumented intersection, and improve on some of those limitationsPavement Mill and Fill2 CabinetsDSL ServiceRemote IP PTZ Camera60 Detection Channels on 4 BIUs in Signal Cabinet

Noblesville Data Acquisition

Use TS 2 Type 1 CabinetBut will use 24 Volt signals interfaced to a Solo ProSolo Pro will collect time stamped state changes on up to 8 digital inputs and display status on video

Example Solo Pro

Long detection zoneShort detection zonesFor Northbound (2) inputs of Phase 2

& 5 Green Status (4) inputs for

detectors (2 spare)

MiniHub Data Collection

8 Discrete InputsSimilar capabilities (logging/video overlay) as West Lafayette site, but with equipment familiar to techs

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

Example Solo Pro Data

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
