Protecting Vulnerable Road Users-V2Motorcycle Demo in Detroit 2013/08 Goals Safety between vehicles and motorcycles (V2M) Reduce vehicle-motorcycle accidents through DSRC Scenario Motorcycle passes a turning van while a vehicle is making a left turn Unique Value Warning the driver of the presence of a motorcycle or potential collision when the motorcycle cannot be seen

Protecting Vulnerable Road Users V2Pedestrian Goals Cooperative safety between vehicles and pedestrians (V2P) Reduce vehicle-pedestrian accidents through DSRC 3 Scenarios 1 ~1.5 m/s Distracted Pedestrian 3 ~1.5 m/s Vehicle Backing Up 10 m ~1.5 m/s ~15 m/s 7.5 m A 7.5 m 2 ~1.5 m/s 7.5 m Rental truck 100 m 75 m Obstructed View ~15 m/s The smartphone can communicate distracted mode of pedestrian to driver 1.On the Phone 2.Listening to Music 3. Texting DSRC Chip in the Phone Unique Value Ability to detect pedestrian even without direct line-of-sight, in the dark, or during low-visibility situations

US-EU V2V/V2I Standards Compare/Contrast Similar architectures Security protocol and physical layer standards are identical Message set data elements are similar However application layer, channel congestion control and performance requirements differs-it is OK to remain different IEEE 1609.2 Security functions SAE J2735 J2945 Message set & data performance requirements Application Layer IEEE 1609.3 1609.4 Network Layer IEEE 802.11p PHY Layer

SAE DSRC J2735 & J2945 Development Strong collaboration among US/EU/JPN on V2V and V2I msg All three regions agreed on using the same Signal Phase & Timing (SPaT) and Map messages SAE J2735 Data Dictionary Data Elements: Vehicle speed Signal Phase Intersection ID Messages: Basic Safety Message (BSM) Signal Phase and Timing (SPaT) Map SAE J2945 Application Specific Performance Requirements J2945.0 common section Provider Service Identifier (PSID) Service Specific Permission (SSP) Message Priority J2945.1 V2V safety Concept of Operations User Needs Functional Requirements Channel Use V2V Communications Scalability Security / Privacy GPS Receiver Configuration Data Element Level Requirements Test procedures J2945.2 (Traffic signal related) Concept of Operations - Signal priority - Signal violation warning User Needs Functional Requirements Message Transmission Interval Channel Use Security

V2I Message Standards Update 1. SAE is closely working with US/EU/JPN experts on SPaT and Map revision for each region s DSRC deployment needs 1 Allow regional variance while maintaining largely identical message contents 2. Examples of some of the EU & Japan specific needs: 1 Adding Queuing info to allow cars/drivers make smarter decisions such as whether to stay in the same turning lane or try to make the turn at the next intersection 2 Adding fuel-efficiency class in the message to advise vehicles to enter/not enter certain area without proper fuel-efficiency class privilege 3. Encourage the regional test bed group to join the message revision process and start using the new format as soon as it is published early 2014 SPaT: tells what phase for what maneuvers will be coming up for how long Map: allow veh. to position itself to the correct lane & signal phase group J2735 rev SPaT & Map limited ballot from 2013 to support EU deployment J2945 rev J2735 J2945 full ballot rev. ready J2735 J2945 Publication?

Challenges for DSRC Deployment 1. Security Framework & Privacy Protection Fundamental trust among data exchange at system level Customers need assurance on privacy protection However the design and operation are complex and need infra. support for tasks such as - Certificate distribution/maintenance - Misbehavior detection and bad-player reporting/list distribution 2. Cooperative System Data Reliability Common understanding of the quality of the data to ensure application performance 3. Standards Development & International SDO Coordination Virtually all OEMs have global presence Many of the deployment use cases on the roadmaps are similar Common/coordinated standards enable simpler design and validation process for global development use 4. V2V Penetration & Early Benefit V2I is a very important piece of the puzzle Industry-Government collaboration is key to success!
