IoT beneath your feet - building smart roads and networks

  1. 1. The IoT Beneath Your Feet: Building Smart Roads and Networks Presented by Israel Lopez for Nevada DOT
  2. 2. All Problems Need Some Sort of Context • Without knowing the context of something it is often difficult to truly understand the problem or the solution Reference: https://www.pinterest.com/pin/161707442844741481/ Reference: http://www.funcage.com/blog/18-amazing-examples-of- optical-illusion-photography/optical-illusion-photo-04/
  3. 3. The State of Nevada • Ranked 7th Largest State (110k square miles) • Carson City, NV is the capital (population 54k) • Ranked 35th in Population (2.89 Million) • 42nd in Density (24.8/sq. mi) • Median Elevation is 5500 ft. • 4th largest producer of Gold in the World • Ranked 15th in Median Household Income ($56k) Reference: https://en.wikipedia.org/wiki/Nevada
  4. 4. IoT Topics • What does a State DOT do? • Data Collection • Real-Time Traffic Management • Backbone and Field Infrastructure • Data Distribution • Advanced Traveler Information Systems
  5. 5. What does a State DOT do?
  6. 6. What does a Department of Transportation Do? • Manage and Maintain Freeways at a defined Level of Service during the following: – Normal Freeway Conditions – Congested Freeway Conditions – Adverse Weather Conditions (wind, flooding, fog) – Severe Crashes and Crashes Related to Weather (Level of Service) – Repair of Roads – Inform the Public, News, and Media So what does this really mean? What is the Context?
  7. 7. Normal Freeway Conditions US-95/US-93/I-15, Las Vegas I-10 at L 202 & SR 51, Phx, AZ São Paulo, Brazil Los Angeles (Unknown)
  8. 8. 8/26/201 6 Congested Freeway Conditions I-405 Freeway in Bel Air, CA Beijing, China São Paulo, Brazil Moscow, Russia
  9. 9. Phoenix, AZ Porter Ranch, CA Unknown Minnesota Adverse Weather Conditions
  10. 10. I-10 at Casa Grande, AZ 710 Freeway at Long Beach I-10 at 35th Ave., Phoenix, AZ I-78 at Bethel Township, PA Severe Crashes and Weather
  11. 11. I-15 near Moapa, NE of Las Vegas Repair Freeways * Caution: Don’t ever drive through fast running water or drive over a compromised roadway.
  12. 12. Freeway Conditions and Crashes can make it feel like….
  13. 13. Data Collection Roadway Sensor Types
  14. 14. Data Collection • Intelligent Transportation Systems (ITS) are advanced applications and technology that aim to provide information on different modes of transport for travelers by making the roads safer, coordinated, and “smarter” Reference (personal rating of 6 for reference): https://en.wikipedia.org/wiki/Intelligent_transportation_system
  15. 15. Data Collection • The Nevada DOT (NDOT) collects the following information from hundreds of these ITS devices types:  Highway Advisory Radio (HAR)  Dedicated Short Range Communications (DSRC)  Ramp Meters  Link and Node Inventory  Vehicle Detectors  Dynamic Message Signs (DMS)  Roadway Weather Information System (RWIS)  Closed Circuit Television (CCTV)
  16. 16. CCTV Camera Cabinet80’ Camera Pole with Detector Full Sized DMS Sign Travel Time Sign (DMS) 30’ pole with Detector
  17. 17. Road Weather Information System Variable Speed Limit Sign (DMS) Highway Advisory Radio Beacon Sign 80’ pole with DSRCHAR Site
  18. 18. Data Collection • The Nevada DOT (NDOT) collects the following information from hundreds of these devices types: – Vehicle Detectors: Detects the presence of vehicles by lane – DMS: Informs the traveler of crashes or weather conditions – RWIS: Detects the current ambient weather conditions and the condition of the roadway pavement – CCTV: Provides visual verification of any issues on the roadway – HAR: Provides audio notification of issues using AM or FM (Radio)
  19. 19. Data Collection • The Nevada DOT (NDOT) collects the following information from hundreds of these devices types: – DSRC: Communicates with Connected Vehicles or Autonomous Vehicles to obtain speed, weather, traction, & other information – Ramp Meter: A device use to reduce congestion by limiting the number of simultaneous vehicles to a steady but constant flow – Node and Link Data: Nodes are arbitrary points along a road and links are arbitrary parts of a road between two nodes
  20. 20. Data Collection • NDOT’s Freeway Management System (FMS), a variant of an Advanced Traffic Management System (ATMS): – Collects all Device Data – Displays the information visually – The Operators in the Traffic Management Center (TMC) make a decision based on this information CCTV Node Inventory Link Inventory DMS Ramp Meter RWIS HAR Events CSS Detectors
  21. 21. Real-Time Traffic Management Sharing of data and video
  22. 22. Real-Time Traffic Management • Operators enter information into an Advanced Traveler Information System (ATIS) to provide traveler information on: Reference: http://ops.fhwa.dot.gov/publications/manag_demand_tis/travelinfo.htm  Travel Times  Emergency Alerts  Alternate Routes  Delays  Crashes / Events  Road Weather
  23. 23. Reference: http://www.its.dot.gov/infographs/index.htm Integrated Corridor Management (Today) A camera monitors and detects congestion due to a disabled vehicle The Operations Centers receive and exchange data and inform the travelers Travelers receive a message about congestion ahead and alternate travel routes or travel modes 511 / ATIS
  24. 24. Real-Time Traffic Management • Integrated Corridor Management Examples: – NDOT & NHP – CCTV cameras and shared use of Spillman CAD – FAST – Las Vegas Metropolitan Area – I-15 Alliance – Utah, NDOT, ADOT and CalTrans (In Process) – I-80 Coalition – Nebraska, Wyoming, UDOT, NDOT & Caltrans – Western States Rural Transportation Technology Implementers Forum (WSRTTIF) (All westerns states west of the Dakotas) I-15 Alliance Reference: http://goo.gl/xxBRWc I-80 Coalition Reference: http://goo.gl/QHViX8 Western States Rural Transportation TIF: http://goo.gl/Bp4KrBFAST Reference: http://goo.gl/7WHPxA
  25. 25. Active Traffic Management and Demand Management (Tomorrow) An Active Traffic Management (ATM) structure will be installed every ½ mile on I-15 in Las Vegas for 18 linear miles. FHWA Reference: http://goo.gl/LKW8Eq NDOT will implement a solution in Las Vegas within 8 months ATM Pres.with BCR (Schilling, 2016): https://goo.gl/xHbma1 San Diego which implemented a similar system has a Benefit Cost Ratio of 9.7:1 with a 20% crash rate and a 46% serious crash reduction
  26. 26. Reference: http://www.its.dot.gov/infographs/index.htm Queue Warning and Speed Harmonization (5 years) Warns drivers of congestion ahead, as well as provides target speed advice
  27. 27. Backbone and Field Infrastructure The growth of the ITS network
  28. 28. Backbone and Field Infrastructure • ITS has Experienced Exponential growth: – CCTV Cameras – 2 cameras in 2010 (Reno) – CCTV Cameras – 63 cameras by 2016 (Reno) – NDOT owned fiber in miles in 2010 – 0 miles (Reno) – NDOT owned fiber in miles by 2016 – 55 miles (Reno) • This is an addition to any provider dark fiber
  29. 29. Backbone and Field Infrastructure • Organizational Members – NDOT works with the Nevada System of Higher Education (NSHE) and the State Enterprise IT Services (EITS) as part of a TEAM – No one entity has the staffing or the personnel for the whole system Reference: NDOT Board Packet, Dated 11-13-2013, Page 17 – 19, Item # 3 https://goo.gl/l0ROcJ Partnership Reference: https://www.ntia.doc.gov/legacy/broadbandgrants/comments/61B6.docx NDOT IT/ITS NSHE EITS
  30. 30. Backbone and Field Infrastructure • NDOT has an extensive infrastructure that uses the following: – Fiber Optic Backbone (10 Gbps or higher) • I-80 Fiber at Reno to I-80 at Utah Border (existing) • I-580 Fiber at I-80 in Reno to California Border in CA (90% complete) • US-50 Fiber at I-580 in Carson City to Ely, NV (In design)
  31. 31. *I-80 = 400 miles (existing) *US-50 = 321 miles (In design) *US-95 = 435 miles (future) *I-580 = 70 miles (90% complete) I-15 = 28 miles existing Lease Lines (redundancy) *We have extensive agreements with L3, Praxis, and AT&T NDOT Dark Fiber Map
  32. 32. We have hundreds of roadway sites along the freeway (CCTV, beacons, DMS, etc.) Each red pyramid represents a site Each blue bubble represents a grouping of sites that are in close proximity Not including mountain top sites we have over 416 sites
  33. 33. • L2 or L3 (existing) single chassis using MLT (ROC to Fiber Hut) • Shortest Path Bridging Upgrade (Shown/Future) • Field devices must be hardened to withstand high temperatures SPB Reference: http://miercom.com/pdf/reports/20111027.pdf Center-to Field (C2F) Communications Fiber Hut Switch (Enterprise) Field Cabinet Switch (Hardened) Video Encoder  Field Hardened Ethernet Switch Field Cabinet   Fiber Optic Branch Cable   SPB (Future)
  34. 34. Backbone and Field Infrastructure DOTs generally Use: • Spanning tree for rings • Multicast for video • Hardened Ethernet Switch =>164°F rating (must use) • SMFO cable is 144 strands on both sides of the freeway • Journey Electricians as network technicians (common) Google Search for STP and DOTs https://goo.gl/hPLArv
  35. 35. Backbone and Field Infrastructure • Due to our limited time we are unable to discuss our other modes of communication: – Point to Point (PtP) – Point to Multi-Point (PTmP) – 3G / 4G communications with Verizon Cloud
  36. 36. Data Distribution
  37. 37. Data Distribution • Once collected the expectation is to share the information across different transportation verticals • All NDOT ITS device data is sent to the Nevada Data Exchange (NDEX) Data Exchange & Data Warehouse Reference: http://www.iteris.com/itsarch/html/appareas/ifclass1apparea12.htm
  38. 38. Data Distribution • The Nevada Data Exchange (NDEX): – The NDEX is the data warehouse for NDOT ITS – The state is broken down into three districts – Each district reports the status of every device in its inventory – Reporting frequency is every 2 minutes
  39. 39. Data Distribution • NDEX (Continued): – The system uses a three-tier security architecture – The web service is available via HTTPS – The NDEX uses Institute of Traffic Engineers (ITE) Traffic Management Data Dictionary 3.01 – The NDEX is subscription and publication based Reference – TMDD Standard: http://www.ite.org/standards/tmdd/3.01.asp
  40. 40. NDEX Network and Software ArchitectureNDEX: • The External Agency Interface (EDEX) handles all External agencies • The Internal Agency Interface (IDEX) handles all Internal agencies • Data can be bi- directional based on a Subscription and Publication model
  41. 41. Nevada Data Exchange (NDEX) - General Concept
  42. 42. Data Distribution • NDEX Publishers and Subscribers – The 511 System subscribes to all device types dialogs – The 511 System then posts the information to the 511 site – Events are entered into the 511 system and are published to the NDEX for other to subscribe – We have multiple subscribers pulling NDOT information Reference – TMDD Standard: http://www.ite.org/standards/tmdd/3.01.asp
  43. 43. Advanced Traveler Information Systems (ATIS) Public Facing Information Systems
  44. 44. Advanced Traveler Information Systems • ATIS Systems – Provides public information regarding road conditions – Commonly done by a regional or local Traffic Management Center (TMC) – Coordinates with police, fire, & support services – Responds to events & enters information in an ATIS system
  45. 45. Reference 1: http://nvroads.com Mobile Application USDOT requires every state to have a 511 / ATIS system per SAFETEA-LU, 23 CFR 511 Reference 2: Section 1201 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). 23 CFR 511: http://ops.fhwa.dot.gov/1201/factsheet/ IVR System: dial 5-1-1 in any State DMS Signs Construction Road Conditions CCTV Cameras Crashes / Events
  46. 46. Video-to-Public (Las Vegas) – Live Streaming Video – H.264 Upgrade in June of 2016 V2P (Internet Explorer Only at this time – 247 streams are available for Las Vegas Area, 59 cameras for Reno, and 24 cameras for Elko: http://www.nevadadot.com/Traveler_Info/Traffic_Cameras/Traffic_Cameras.aspx
  47. 47. OSS Weather Share (Caltrans) has access to all the Forum Member’s Information Reference: http://oss.weathershare.org/# In comparison to other DOTs we have a rather limited implementation of ITS in comparison to States like Colorado (comparable Land Mass) and Utah (comparable Population)
  48. 48. Advanced Traveler Information Systems • The Future of ATIS and ATMS – The lines between these application types will become blurred – As the ATMS gathers information the system will autonomously notify vehicles in the field – Information will become bi-directional – This is already happening with Connected Vehicles
  49. 49. High Level Concept – Vehicle-to-Vehicle (V2V) Communications
  50. 50. High Level Concept – Vehicle-to-Infrastructure (V2I) Communications
  51. 51.
