  • Security and Data Access ----------------------------------- Data access in both the user interface and XML API that follow the Maryland CHART model (proven to scale to large systems with multiple organizations contributing devices and many users who should be able to access subsets of the available data) -- Segments, routes and stations are owned by an organization -- Rights are granted to users on an organization basis (This user can see only segments owned by this organization or that organization). -- A user can be granted the same right for several organizations. In this case they will be able to access data from any of the granted organizations. Notification ---------------- - Notification groups subscribe for email notifications based on the owning organization of the station or segment. Thus a user can choose to be notified only if segments owned by &quot;baltimore city&quot; a configured travel time, etc. - Email alerts (to configurable notification groups) when segments exceed configurable travel times - Email alerts (to configurable notification groups) when stations are not reporting data for &gt; configurable period of time - Email alerts (to configurable notification groups) when stations are reporting hardware errors - Email alerts (to configurable notification groups) when stations are reporting battery levels below a configured value

    1. 1. Recent Advances TraffaxTraffic Monitoring Equipment<br />Donna Nelson, PhD<br />Marketing Director, Traffax Inc<br />dcnelson@traffaxinc.com<br />240-447-8612<br />www.traffaxinc.com<br />
    2. 2. Traffax, Inc<br />Formed in 2009. <br />Technology commercialized from University of Maryland.<br />Patents pending.<br />Core technology is field-hardened with over 50,000 hours of “real” use.<br />Growing base of happy customers. <br />Expanding network of high-quality, seasoned distributors.<br />Provides portable and permanent applications for traffic studies and realtime monitoring.<br />
    3. 3. BluFax Concept<br />A<br />Each Bluetooth devices has a unique, but anonymous device ID.<br />BluFax devices record:<br />ID of each detectable device.<br />Time stamp ID detected.<br />BluFax unit ID<br />BluFax location coordinates. <br />Distance L<br />B<br />BluStat Software:<br />Processes station data.<br />Filters and processes data.<br />Outputs graphics and results.<br />User-configurable parameters.<br />Detection Zones<br />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.<br />
    4. 4. BluFax Anatomy<br />SD Card: Stores up to 2 years data on a micro SD card. Readable with standard adapter<br />GPS: Internal GPS for location and time reference.<br />Power: Accepts battery, solar, 12v, 110 Powered by an AGM-type battery .<br />Operates at least 14 days on a charge.<br />Data Transmission: Built-in GSM Cellular, serial port, data terminal.<br />USB port for Bluetooth Radio/Antenna. Std. configuration Class 1 w/100m diameter range. Accepts other configurations..<br />LED Start-up Sequence. LED lights confirm successful startup and GPS lock. <br />
    5. 5. Spatially-based Concept<br />Applications build on the concept of comparing the time at which unique device IDs are detected by pairs of units. <br />Segments are defined between pairs of stations <br />A<br />C<br />B<br />A<br />B<br />E<br />D<br />F<br />Direction of travel for analysis is based on the order in which stations are defined for segments.<br />B<br />A<br />Stations<br />A<br />B<br />
    6. 6. O and D Pairs<br />Once segments (pairs of stations) have been defined, users can define routes (corridors) and O-D pairs for analysis.<br />O-D Pairs can be defined between any pair of stations that have been defined as a segment.<br />A<br />C<br />B<br />E<br />D<br />F<br />BluStat software will output travel-time and matched pairs (e.g. sample sizes) in a matrix format.<br />B<br />The user can define specific segments, pairs, and time windows for analysis. <br />A<br />E<br />D<br />
    7. 7. Bluetooth Characteristics<br />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. <br />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. <br />Pick up multi-modal trips<br />A<br />B<br />C<br />Follow specific signals over multiple segments.<br />
    8. 8. Data Collection Concepts<br />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.<br />Surveys<br />Floating cars<br />Bluetooth<br />Cellular<br />Licence-plate matching<br />Volume Counts<br />Classifications<br />Manual counts<br />Some video studies.<br />
    9. 9. BluFAX Sample Sizes<br />BluFAX data are a sample. The size of the sample is based on: <br />Volume: Expected traffic volume passing a specific unit. <br />Population w/ devices. The proportion of the population passing a unit that carry a detectable device. <br />Station detections are the number of unique IDs captured by a single BluFax unit during some specified time window.<br />Matched Pairs are the number of MAC IDs that were detected by pairs of stations during some specified time window.<br />
    10. 10. BluFax System Components<br />
    11. 11. Realtime or not?<br />BluFax equipment supports a full range of applications from off-line studies and remote-data reporting, to real time traffic monitoring. <br />
    12. 12. Portable to Permanent<br />The same core BluFax units support all types of installations from very short-term studies to permanent installations.<br />Long term deployments. BluFax and/or core software processing capabilities may be integrated into existing infrastructure and/or software.<br />Studies or instillations more than two weeks or so, that may or may not tie into existing power or communications infrastructure<br />Short-term studies are likely to use battery operated units secured to infrastructure or mounted on existing poles.<br />All types of installations can utilize BluStat or realtime BluFaxWeb, as needed<br />

    44. 44. Utah Demo Setup<br />Six units set up as shown in Sandy, Utah.<br />Bangerter Highway. <br />The objective was to collect travel-times along the corridor from 1 to 6, but also to analyze data from 2,3,4, and 5 to estimate travel times and delay through an intersection by movement.<br />1<br />2<br />3<br />4<br />5<br />6<br />
    45. 45. Data for Bangerter Highway <br />
    46. 46. 1-Hour Sample sizes for travel-time study along Bangerter Highway in Sandy Utah from Station 1 to Station 6<br />
    47. 47. Travel time Matrix 8 to 9 AMMonday, November 15, 2010<br />Sample sizes for turning movements through the Intersection are small for a one-hour period. However, many customers collect data for 3 hour peak periods, for 2 to 3 “similar” days. <br />
    48. 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. <br />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. <br />Flagstaff Arizona Traveltime<br />
    49. 49. BluFaxWeb Map Display<br />Stations (units) are paired to define segments. <br />BluFax units are shown as blue diamonds<br />
    50. 50. Alternative Routes<br />Five different routes were defined in Flagstaff that represent alternative paths drivers may take through the area. <br />
