11 Overview of USDOT Roadside Unit Specification v4.1 Deborah Curtis, USDOT Chris Stanley, Leidos Ed Leslie, Leidos

12 USDOT Roadside Unit 4.1 Specifications Roadside devices to enable communication between connected vehicles and existing traffic control equipment & systems Federal Highway Administration Saxton Transportation Operations Lab 12

13 RSU Overview RSU provides information about infrastructure (e.g. SPaT/MAP from traffic controller or TIM) RSU collects information about vehicles (e.g. BSM, PVD) On-Board Unit (OBU) receives and process the messages based on its current GPS co-ordinates RSU broadcasts wave service advertisements (WSA) which are received by OBU and OBU sets the channel and routing information accordingly IP connectivity to OBU is achieved by running WSA and IP service applications on RSU 13

14 RSU with 3.0 vs. 4.1 Hardware and Software RSU with 4.1 Devices Hardware: 4.1 devices should include a hardware security module (HSM) to provide secure storage and processing (required by SCMS) Software: requires more use of Simple Network Management Protocol (SNMP) and provides a MIB adds health and status monitoring features increases security requirements (e.g. passwords, ports, etc.) Require the latest (2016) version of connected vehicle (CV) specifications with examples 14

15 SNMP Specifications Intent is to move toward Simple Network Management Protocol (SNMP) rather than direct loading of message files by SCP, etc. Simplify device interaction Improve security Simplify management of a large number of devices 15

16 Message Forwarding Specifications Should the RSU forward (1609) headers? Headers contain useful information Make it configurable (through NTCIP 1218) How should the WSA handle Immediate Forward messages? IF messages don t have a predefined duration Advertise the service as long as the message is transmitted? TMC RSU 16

17 RSU Set Specifications Intent is to allow a large intersection with poor line-of-sight to be equipped with multiple RSUs that will provide the same messages and improve the coverage of DSRC radios Operate as a single unit and appear to vehicles and to a traffic management center (TMC) as a single unit RSU SLAVE TMC RSU MASTER RSU SLAVE RSU SLAVE 17

18 Functional Test Summary Physical Positioning SNMP Logging Security Message Forwarding Wave Service Advertisement (WSA) 18

19 Future Releases A 5.0 release is expected before widespread deployment (years away) Account for lessons learned Build on experience of Pilots, SPaT challenge participants, and other deployers FAQ document will be available Further questions can be asked through the CVCS support site RSU 4.1 Specification: RSU 4.1 Test plan: 19

26 Florida s CV Program 26

27 AASHTO SPaT Challenge Challenge state and local public sector transportation Instructure Owners & Operators (IO&Os) to deploy Dedicated Short Range Communication (DSRC) infrastructure with SPaT broadcasts in at least one coordinated corridor or network (approximately 20 signalized intersections) in each state by January Intersection in 50 states by 2020! 27

28 SPaT Pilot Project 21 signalized intersections along US 90 (Mahan Drive) in Tallahassee FDOT and City of Tallahassee Partnership City installed equipment Pre-deployment testing at the Traffic Engineering Research Laboratory (TERL) Vendor selected in Q Deployment completed 28

29 System Knowledge Controller/Roadside Unit Communication Questions to ask prior to installation and deployment: Is there anything that needs to be installed (physically or software) to the existing infrastructure? How will the controller communicate to the Roadside Unit (RSU)? MAP file configuration during testing phase Both Google (or other map site) and onsite inspection need to be performed Need controller phase/lane assignment or some indications will display incorrectly Where will the MAP file reside? Any other considerations for the MAP file? 29

30 Traffic Controller Ensure the traffic controller firmware and any other SPaT/CV software/hardware are compatible and installed in the cabinet. 30

31 Roadside Units (RSU) Designate and configure the unit before installation Note: MAC, IP, and other unique attributes before installation Tallahassee location (based on RSU manufacturer) required two RSUs per intersection at multiple locations Conduct a study to verify if two RSUs at one intersection is needed for line of sight Ensure antennae, cable entry, and any other access points to the device are secured and water tight 31

32 Pre-Deployment Installation at TERL

33 RSU and Antenna Placement on Mast Arm/Spanwire

34 Radio Antenna on the Vehicle

35 Multi-Channel Test Tool (MCTT) Used to verify signal strength and quality as well as display raw data being received from the RSUs Can be a DSRC radio reserved specifically for use as and configured to detect RSU messages with laptop computer or other device Designate and configure unit before installation Note: MAC, IP, and other unique attributes before installation 35

36 Configuration varies On-Board Unit (OBU) Some manufacturer OBUs do not require the external computer Ensure the OBU can process and handle the flood of SPaT/MAP messages when multiple RSUs are within range of the OBU. Designate and configure unit before installation 36

37 On-Board Unit (OBU) OBUs can comprise of a DSRC radio and GPS connected to a Raspberry Pi, and includes a cellular modem and a router with WiFi to an tablet. Complete OBU (except for the tablet) Modem Pi New Modem 37

38 Pre-Deployment Testing

39 SPaT Pilot Project Pre-Deployment Testing

40 Field Deployment

41 SPaT Pilot Project Lessons Learned Two stage FCC licensing: First: blanket approval for use of DSRC Second: Location (GPS detail, mounting height of devices, make and model of RSU s and OBU s) Ensure devices are licensed by FCC for deployment Proposers should ask questions during the procurement process regarding device compatibility with controllers Ensure the MAPs are properly coded and the Uper Hex code is validated for field testing; offer vendors to develop their own Consider expanding SPaT with other CV technologies including bike-ped safety, etc.

45 Agenda Introduction to Licensing FCC RSU Site Selection Procurement Cabinet Audit/Installations Management and Monitoring (SoH) O&M Recommendations 45

46 Introduction to Licensing RSUs Dedicated Short Range Communication 5.9G band FCC Governing Agency Initial pilots use under USDOT license grant Effectively a fixed radio roadside unit (RSU) New sites/deployments Need to request FCC site specific license Includes SPaT Challenge locations 46

47 DSRC Licensing Perform Site Selection gather GPS position for RSU 2. Check TOWAIR Get determination of No Hazard - File FAA Form Apply for Geographic License - FCC FORM 601 Main Form and Schedule D 5. Register sites under the Geographic license FCC Form 601 and Schedule M 6. Certify construction of the RSU FCC Form 601 and Schedule K. 47

48 DSRC Spectrum Allocation Source Toyota Technology Center, USA 48

49 RSU Design Considerations Collocation: Wherever feasible, CV equipment will be collocated at CCTV, DMS or traffic signal locations sites to take advantage of the existing roadside infrastructure, power and communications equipment. USDOT Compliance - The RSU to be installed on projects shall meet the latest 5.9GHz DSRC Roadside Equipment Device Specification issued by the USDOT v4.1a. Mounting Height - Per the FCC regulations the DSRC radio shall be mounted at a maximum height of 8 meters or around 26 feet above the roadway surface before a maximum Equivalent Isotopically Radiated Power (EIRP) limitation occurs. 49

50 Site Selection Clear Line of Sight - RSU mounting location shall be optimized to achieve clear line of sight free of RF signal path interference from trees, bridges, overpasses and other structures. Needs to be hard fixed mount location Avoid sway/vibration off mast/strain poles Spectrum Analysis - DSRC spectrum coordination must be completed to assure all FCC regulatory requirements are met and to ensure no interference with other existing RF signals is present. Detection Range: A maximum detection range of 1200 meter radius using for the RSU placement. 50
