Time intensive Costly Highly variable Difficult to be statistically significant Sometimes intrusive
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
