3 What is Safety Pilot Safety Pilot is: Model for a national deployment of the technology Designed to determine the effectiveness of the safety applications at reducing crashes Designed to determine how real-world drivers will respond to the safety applications Safety Pilot will also tests mobility and sustainability applications $18M, 2.5 year program 1-year deployment began August 21,

10 Connected Vehicle Communications Vehicle-to-Vehicle (V2V) Vehicle-to-Infrastructure (V2I) Majority of safety applications can be accommodated using V2V Intersection-related safety and mobility applications require V2I V2I will have some role in security system architecture 10

11 V2V Applications Much application development conducted by USDOT and Crash Avoidance Metric Partnership (CAMP) 60 CAMP integrated vehicles in-use for Safety Pilot 11

13 V2I Applications Primarily applications which require traffic signal-related data Signal Phase and Timing (SPaT) message set is standardized way to delivery signal data Applications include: Signal violation alert Intersection collision avoidance Pedestrian conflict warning Optimal travel speed (progression) 13

14 V2I Applications Curve warning application Infrastructure-based RSE broadcasts Traveler Information Message (TIM) Location sensitivity still being evaluated 14

16 Roadside Infrastructure Several roadside infrastructure elements required: DSRC Roadside Equipment (RSE) SPaT-enabled traffic signal controllers Backhaul communications network Back-end data storage and processing System also requires detailed physical data for application messaging TIM and Geographic Intersection Description (GID) 16

17 Roadside Equipment (RSE) Tx/Rx information with Vehicle SPaT/GID Curve Speed Warning (TIM) Others Data offload Security gateway

25 SPaT-Enabled Traffic Controllers Siemens and Econolite

26 Backhaul Communications Network Enables multiple functions: Acquiring data from vehicles Monitoring system health Managing RSE network Serving as a gateway for security system Significant back-end data storage and processing requirements 26

27 Backhaul Communications Network 27

28 GID and TIM Development Detailed survey-level geographic data required for intersection- and curve-related applications Data represented and transmitted in standard format (GID and TIM) GID coupled with SPaT data to provide required information for intersection-related applications 28

29 GID/MAP files

31 Infrastructure Readiness Lessons HUGE amount of data With only 1,000 vehicles deployed, measured in Terabytes/week Requires high-bandwidth backhaul connections to offload from RSEs Warehousing and processing becomes significant challenge 31

32 Infrastructure Readiness Lessons Security Systems Current architecture uses over-the-air (OTA) transmission of security credentials from RSEs to vehicles Large files which require significant network bandwidth to deliver Will continue to evolve as system development for a full-scale deployment continues 32

33 Infrastructure Readiness Lessons Networking USDOT specifications call for networking using Internet Protocol version 6 (IPv6) Most of the world still uses IPv4 IPv6 greatly increases complexity of network routing Many service providers (particularly cellular/mobile networks) not yet ready to support IPv6 33

34 Infrastructure Readiness Lessons SPaT-Based Applications Development not as mature as anticipated Significant challenge in addressing message validity in actuated and adaptive systems 34

35 Agenda Safety Pilot Program overview V2V and V2I communications and applications Roadside infrastructure elements Infrastructure readiness lessons What can you do to prepare? 35

36 What can you do to prepare? Look for opportunities to develop robust traffic signal communications networks Incorporate provision for conduit/fiber-optic installation as part of road/bridge construction Upgrade signal controllers with Ethernet connectivity Consider future cabinet space 36
