13 SPaT Challenge The basis of the SPaT Challenge is to broadcast: SPaT Message MAP Message Using DSRC technologies. Subsequent efforts could include: Broadcast a Security Certificate (SCMS) Broadcast a GPS Correction Message (RTCM) Install OBUs in vehicles (Fleet Challenge) Implement V2I Applications 13

14 SCMS Systems Webinar 6 included a presentation on SCMS systems, functions and needs Trust is the key element of SCMS Recommended that we implement certificate systems sooner, rather than later USDOT led the creation of the SCMS Proof-of- Concept system to support CV Pilots Proof-of-Concept system not suitable to scale up for national deployment No overall policy framework / No misbehavior detection 14

15 SCMS Systems FHWA recently held two workshops to develop strategies for deploying a full-scale SCMS system Governance and Oversight High-level Policies Roles and Responsibilities Business and Financial Models A National SCMS System is not imminent 15

16 The current landscape: SCMS Systems CV Pilot sites are using a private certificate provider GM (Cadillac) has a certificate system for their models Some agencies are exploring certificates through private providers These workable and available solutions are not the same as a complete national SCMS system 16

17 Federal AV Guidance New guidance for automated vehicles (ver 3.0) released in September Increases focus on other modes Reiterates that connectivity (V2V and V2X) is a complementary technology that will enhance automation SPaT Challenge is mentioned USDOT encourages continued deployment and use of the 5.9GHz spectrum but does not promote any specific technology 17

21 Pilot Deployment Objectives Primary goal: Develop back-end infrastructure, network components, and business processes to support broad vehicle to infrastructure applications that is broadcast-medium agnostic, scalable, and sustainable. Secondary goal: Begin broad installation of roadside units and equipped vehicles to facilitate applications that improve safety and mobility. Primary Application Spaces: Mobility Safety Freight Partnerships

45 Project Overview Project awarded to Econolite on July 20, 2017 Initial approved equipment were Savari RSUs & OBUs Anticipated completion time was estimated 19 weeks from data of availability 20 networked intersections were in the project scope Procurement method was Turn-key Payment type was Itemized Total Project cost was $506, or $25,347.40/site 6

46 Existing Infrastructure Existing signal infrastructure included NEMA TS2 Cabinets with 2070E controllers and Econolite ASC/3 software The system resides on a Ethernet fiber optic network The central software is Econolite Centracs 2.x 7

47 Required Upgrades Upgrade the existing 2070E controller units Replaced the existing B/1E CPU modules with C Replaced ASC/3 OS9 local controller software with ASC/3 Linux 8

48 Additional Equipment RSUs CV CoProcessor PoE Injectors Surge suppressors Cabling Signal pole mounting hardware 9

49 Initial Test Setup SPaT equipment were installed at the DOT facility in Garner, NC to conduct proof of concept testing Equipment included: Econolite Cobalt controller and ASC/3 software Network Switch PoE Injector Test RSU and OBU 10

50 Initial Test Setup Contractor created MAP & SPaT messages Installed Test OBU with HMI Verified SPaT & Map messages Validated design concepts 11

51 Installation After proof of concept, 20 Savari RSUs and 5 Savari OBUs were ordered & installed Savari missed several delivery dates Units provided did not meet expectation and were not functioning properly and reliably QA issues from factory affected delivery deadlines and product functionality Technical support was poor and hard to come by 12

52 Reboot On December 2017, decision was made to cancel project with Savari Restart the process with evaluation of multiple RSUs & OBUs 13

53 Fresh Start Invitation to Demonstrate was sent to multiple vendors soliciting participation in January 2018 The following RSUs were demonstrated and evaluated: Siemens Kapsch TrafficCast Lear Applied Information Savari 14

54 Moving Forward Demonstrations wrapped up in March 2018 Evaluation was performed by a team with members from: NCDOT Town of Cary, NC Econolite City of Concord, NC 15

55 Evaluation Some of Evaluation Criteria Included: Functionality Applications Interoperability Documentation Ease of Installation Configuration Packaging/form factor Support MAP Development OTA Firmware Update 16

56 Ranking Result of evaluation led to the following ranking 1. Kapsch 2. Siemens 3. Lear 4. TrafficCast 5. Applied Information 6. Savari Since Siemens didn t offer OBU, 1 & 3 were selected for installation on this project Applied Information did not offer a DSRC solution, so they ranked lower for the purpose of this project 17

57 Installation New RSUs were ordered in May, 2018 Delivery of RSUs late June/early July Installation and integration completed in July Training completed in August System has been in operation since July 18

61 Lessons Learned Apply for FCC Licensing early in the process Write detailed functional requirements Evaluate multiple products Require comprehensive testing and training Require complete documentation for equipment and construction Be hands-on if you want to learn 22

62 Lessons Learned CoProcessors provided as part of project ended up being unnecessary Lead time for equipment may be longer than expected Ensure everyone meets the current specifications. Compatibility issues between equipment may exist due to changing specifications. Need for easier MAP file creation 23

63 Lessons Learned Expect delays! FCC licensing Equipment lead times Weather Expect challenges! Reboot of project Device configuration and MAP file creation Don t expect too much! Applications are still being developed Compatibility issues will arise 24

64 Lessons Learned Isolate DSRC Radio electrically from metal signal pole! 25

65 What is Next Expansion of the test corridor to another 18 intersections Deploy additional technology with signal system projects Deploy new signals with hardware & software ready for CV deployment Develop a statewide CV deployment policy 26
