1. Performance Measurements Using MAC Addressable Technology TPB MOITS Traffic Signals and Operations Subcommittee November 12, 2008

2. Data Collection  Time intensive  Costly  Highly variable  Difficult to be statistically significant  Sometimes intrusive

3. Performance Measures & Techniques  Travel Time –Probe vehicles –GPS tracking –Toll tags  Volume & Speed –Road tubes –System detectors –Toll tags  Origin-Destination/Route Choice –License plate surveys –Surveys

4. New Technique Process  Track MAC Addressable Devices to Determine Travel Speed –Set up antenna locations Flexibility on number and locations –Use portable antennas to log device signal Unique signature for each device Time-stamp logs into a database –Match MAC Address Data mining programs available –Calculate performance measure

5. MAC Addressable Technologies - Background  MAC Address –Devices that have a 48 bit UNIQUE address assigned to a device by its manufacturer  Bluetooth Devices –Cell Phones –Hands free units –MP3 Players –Vehicles  3 Different Classes with Operating Ranges –Class 1 – 100 meters –Class 2 – 10 meters – Most common –Class 3 – 1 meter

6. Sample Project  Preliminary Study –Purdue University & Indiana Department of Transportation –Indiana Motor Speedway (IMS) – Brickyard 400 –I-65 to IMS  Investigate travel patterns and characteristics –Before and after event –Highway and arterial data
