Performance Measurements Using MAC Addressable Technology TPB MOITS Traffic Signals and Operations Subcommittee November 12, 2008
Data Collection • Time intensive • Costly • Highly variable • Difficult to be statistically significant • Sometimes intrusive
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
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
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
Workshop Details • Professor Darcy Bullock – Purdue University • Professor Phil Tarnoff – University of Maryland • Friday, November 21, 2008 • 10:00 AM – 2:00 PM • SHA OOTS Training Room – Hanover Complex
Workshop Details - Agenda • 10:00 AM – 11:45 AM • Prof. Darcy Bullock • Prof. Phil Tarnoff • 11:45 AM – 12:30 PM • Lunch (TBD) • 12:30 PM – 2:00 PM • Roundtable Discussion • Focus on applicability of technology and technique to various transportation engineering fields • Possible revolution in data collection and reliability
