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

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
