  1. TransPHAT IP Radios Glenn Anderson Traffic Operations – System Operations Branch 2012 Traffic Engineers Meeting

  2. TransSTAMP, what is it? • A system to automatically monitor the performance of our roadways • At this time we are focusing on arterials • Easier to deploy on interstates

  3. Bluetooth • Approx 10% of vehicles have Bluetooth “on” • Ubiquitous

  4. TransSTAMP Concept of Operations • A Bluetooth device constantly broadcasts its unique address (MAC) so that other devices can find it and pair with it. • If you listen for passing devices you can match the address at downstream locations to determine the travel time.

  5. Widely used

  6. In-house solution

  7. Why build in-house? • Integration with existing radios and routers • Remote communications to 1300 signals • Existing network can handle the data • Firewall problems previously worked through • No duplicate maintenance costs • KYTC devices share existing signal network • Initial reader cost • Commercial units - $5000 • KYTC unit $200 • Lower cost means we can install hundreds

  8. Contractual issues • Recurring charges • Preferred business model is a service (service = continuous cash flow) • Cellular charges (a router at every reader) • $50/reader/month • Data processing charges • $50/reader/month, more cash flow • Sole Source? • Rebidding issues • Apples vs Oranges if you have multiple vendors

  9. GIS Integration • No national standards for roadway coding • County, Route, Milepoint • KY milepoints start over at each county line • Vendors forced into using least common denominator • Google maps • TIGER maps • TransSTAMP uses the KYTC GIS layers • We leverage our existing GIS data • Segment speed limits • Linking to traffic signal layer

  10. Data ownership • KYTC owns our data and can distribute as we see fit • Data timeliness • Readers are polled every 5 minutes • Select segments will be automatically processed • Transparency in data processing • No “secret algorithms” • Performance measures that we define and understand • Still working on the PMs

  11. Current Locations 75 TransSTAMP Readers: Paducah, Murray, Hopkinsville, Elizabethtown, Bardstown, Boone Co, Kenton Co, Frankfort, Versailles, London

  12. Radcliff & E-Town

  13. 8 mile segment, US 60 Versailles to Frankfort, easy peasy

  14. 1 mile segment, Frankfort, Chenault to US 421

  15. Another source of error – detection raduis300’ range with no attenuationmore attenuation = more precision but fewer samples

  16. 85th percentile speeds: 6:00 – 7:00 46.7 mph 7:00 – 8:00 25.5 mph 8:00 – 9:00 44.9 mph 1.4 mile segment, Kenton Co. KY 17 Tuscany to I 275

  17. Single point data – no matching • “Delay” – number of times a single device is detected before it leaves the area • “Volume” – raw number of unique MAC addresses detected

  18. Pros • Continuous 24/7 travel time runs by thousands of “real” drivers • Long term trends visible • Reduces the need for GPSTravel data collection • Supports MAP-21 federal initiative • Can identify the time of day a problem is occurring • Can identify if the congestion on a certain day was abnormal • Bonus data such as “delay” and “volume” • O-D Studies possible

  19. Cons • Accuracy suffers on shorter segments • For length < .3 mi the data is essentially unusable • Delay includes all approaches • Good for an overall PM of the arterial • Bad since you cannot see just the coordinated direction • Does not replace eyes in the field • Does not show exactly where the delay is occurring or how to fix it • Outlying data points inevitable

  20. Sharing the data • GIS Layer (future) • Standard Segments • Standard Time Periods • Standard Performance Measurements • Color coded map • Custom Segments and periods – call • User friendly tool for analyzing data • O-D tools (future)

  21. Our biggest obstacle:Finance Cabinet IT Procurement $51

  22. TransPHAT News Version 3.0.8 – April 2012 Adds some support for IP Radios

  23. TransPHAT News • Changes due to IP Radios • Communicate with multiple signals simultaneously • TransACT (Automatic Timing Comparison) not finished • System Wide observe features may be possible • Second by second display may be limited by radio bandwidth • Automatic monitoring of RSSI and Temperature possible

  24. TransPHAT News • An update is coming • LabVIEW 2012 Run Time Engine • Full installation will be required for next version • At least its not Adobe Flash Player… • Questions, Problems, Suggestions? • Very little feedback the last few years – is this good?

  25. New Controllers, The Future?

  26. IP Radios • Old network • Ethernet (router) at master cabinet • Serial radios at locals • New network • Ethernet (router) at master cabinet • Ethernet radios at each local • Multiple devices can now share the network • TransSTAMP • Conflict Monitors • Cameras • Detectors • Controllers

  27. IP Radio Benefits • Small size • Extremely sensitive – good range • Remote Access and diagnostics • Multiple Repeating possible • Network ID is text – easier to interpret • Easy to program • Serial and Ethernet interface • Lower cost by about 1/2

  28. Repeating Example: 3 levels of repeaters

  29. IP Radios – current issues • “De sensitization” in certain installations • Repeaters? • Cabinets/Poles/Spans with grounding problems • New model adds additional surge protection • Have same problems with Encom 5200, we just do not have the ability to see it happening remotely

  30. Remote management via browser • IP address of the router • ID of the traffic signal • The number 51000 • 166.136.115.88:51006 • Port = 51000+ID (#6) • Username = admin • Password = zombie
