This document provides an overview of Traffax Inc.'s Bluetooth-based traffic monitoring equipment and software called BluFax. It describes how BluFax uses Bluetooth detectors to capture unique device IDs from passing vehicles to calculate travel times and origin-destination patterns. The document outlines BluFax's applications for traffic studies, work zone monitoring, and real-time traffic monitoring. It also summarizes the components, software, sample sizes needed, and provides examples of BluFax installations.

2. Traffax, Inc Formed in 2009. Technology commercialized from University of Maryland. Patents pending. Core technology is field-hardened with over 50,000 hours of “real” use. Growing base of happy customers. Expanding network of high-quality, seasoned distributors. Provides portable and permanent applications for traffic studies and realtime monitoring.

3. BluFax Concept A Each Bluetooth devices has a unique, but anonymous device ID. BluFax devices record: ID of each detectable device. Time stamp ID detected. BluFax unit ID BluFax location coordinates. Distance L B BluStat Software: Processes station data. Filters and processes data. Outputs graphics and results. User-configurable parameters. Detection Zones Detection zones. IDs are detected within a detection zone, the size and shape of which varies based on the Level of Bluetooth radio and the antenna configuration.

4. BluFax Anatomy SD Card: Stores up to 2 years data on a micro SD card. Readable with standard adapter GPS: Internal GPS for location and time reference. Power: Accepts battery, solar, 12v, 110 Powered by an AGM-type battery . Operates at least 14 days on a charge. Data Transmission: Built-in GSM Cellular, serial port, data terminal. USB port for Bluetooth Radio/Antenna. Std. configuration Class 1 w/100m diameter range. Accepts other configurations.. LED Start-up Sequence. LED lights confirm successful startup and GPS lock.

5. Spatially-based Concept Applications build on the concept of comparing the time at which unique device IDs are detected by pairs of units. Segments are defined between pairs of stations A C B A B E D F Direction of travel for analysis is based on the order in which stations are defined for segments. B A Stations A B

6. O and D Pairs Once segments (pairs of stations) have been defined, users can define routes (corridors) and O-D pairs for analysis. O-D Pairs can be defined between any pair of stations that have been defined as a segment. A C B E D F BluStat software will output travel-time and matched pairs (e.g. sample sizes) in a matrix format. B The user can define specific segments, pairs, and time windows for analysis. A E D

7. Bluetooth Characteristics The same basic principles apply to most study types, however the detailed design of the study and strategies for data analysis are tailored to the situation. The majority of detectable devices are carried by an individual on foot, in an automobile, truck, bus, in the local coffee shop; or vehicles in main lanes and adjacent HOV lanes. Pick up multi-modal trips A B C Follow specific signals over multiple segments.

8. Data Collection Concepts Samples needed to provide results that “represent” all traffic vary for different applications, however, a healthy sample size provides results that are sufficient for traffic or planning studies. Surveys Floating cars Bluetooth Cellular Licence-plate matching Volume Counts Classifications Manual counts Some video studies.

9. BluFAX Sample Sizes BluFAX data are a sample. The size of the sample is based on: Volume: Expected traffic volume passing a specific unit. Population w/ devices. The proportion of the population passing a unit that carry a detectable device. Station detections are the number of unique IDs captured by a single BluFax unit during some specified time window. Matched Pairs are the number of MAC IDs that were detected by pairs of stations during some specified time window.

11. Realtime or not? BluFax equipment supports a full range of applications from off-line studies and remote-data reporting, to real time traffic monitoring.

12. Portable to Permanent The same core BluFax units support all types of installations from very short-term studies to permanent installations. Long term deployments. BluFax and/or core software processing capabilities may be integrated into existing infrastructure and/or software. Studies or instillations more than two weeks or so, that may or may not tie into existing power or communications infrastructure Short-term studies are likely to use battery operated units secured to infrastructure or mounted on existing poles. All types of installations can utilize BluStat or realtime BluFaxWeb, as needed

27. Combination of time and location The combination of time and location data is very powerful! Allows comparisons of travel-time and speed data among multiple routes or parts of routes. Combination of BluFax capabilities and software features opens up new opportunities for customers!

28. Intersections and Interchanges Turning movement proportions and travel-time (delay) through interchanges, intersections, and roundabouts are measured by placing BluFax units at each approach. A complex interchange is treated like a small-scale O-D study. All twelve movements for a complex interchange can be captured with as few as four units. The key is to ensure that sample sizes on each segment are sufficient for your study needs. Once units are in place, the additional costs associated with collecting from 1 to 14 days of data are minimal.

29. Volumes and Detection Rates 2/24/2011 24 BluFAX does not collect traffic volumes, however, Studies indicate that detection rates track to volumes for comparable time periods. Proportion of turning movements for arterial intersections and interchanges support this….. Detections can be compared to volume counts to establish a baseline for a specific location.

48. Flagstaff sits at 7,000 feet elevation approximately 2.5 hours drive north from Phoenix, Arizona. The Arizona Snow bowl is the local ski area located north of Flagstaff on US 180 and attracts 200,000-300,000 skiers per year. The Flagstaff Metropolitan Planning Organization and its member agencies; the City of Flagstaff, Coconino County and the Arizona Department of Transportation are seeking an intelligent transportation system solution to support collection of travel time data and real-time reporting to the traveling public within the corridor.
