Performance Measures & TechniquesPerformance 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

New Technique ProcessNew 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

MAC Addressable Technologies - BackgroundMAC 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
