ONE SYSTEM MULTIPLE SYSTEMS
MARY BARRA ITS WORLD CONGRESS We are not doing anything for the sake of the technology itself. Our customers expect us to help mitigate... if not eliminate... the congestion... pollution... and traffic accidents that are the downsides of automobiles. That's why I am asking ask all of you to accelerate your work in the field as well. Mary Barra, Chief Executive Officer and Chairman of the General Motors Company

CONNECTED VEHICLE PILOT DEPLOYMENT PROGRAM
COMING SOON.. SMART City Challenge ($50 Million) NHTSA Rule Making 10-year, nearly $4 billion investment in Automated Technology FAST ACT
V2I DEPLOYMENT COALITION Connected and Automated Vehicle Executive Leadership Team V2I Deployment Coalition V2IDC Executive Committee USDOT - ITS JPO - FHWA - FTA - NHTSA TWG 1: Deployment Initiatives TWG 2: Deployment Research TWG 3: Infrastructure Operator, OEM, and Supplier Partnerships TWG 4: Deployment Guidance TWG 5: Deployment Standards
V2I DC - GOALS Goal #1: Help to accelerate the deployment of V2I technologies at intersections where the majority of crashes and/or congestion occur; Goal #2: Help to accelerate the deployment of V2I technologies to support end of queue warnings in locations with high rates of rear-end collisions; Goal #3: Help to accelerate the deployment of V2I technologies for work zone management; and Goal #4: Help to accelerate the deployment of V2I technologies for curve warning systems.
CAMP V2I CONSORTIUM
CAMP SAFETY APPLICATION The CAMP V2I Safety Applications project is implementing: 1. Red Light Violation Warning 2. Curve Speed Warning 3. Reduced Speed Zone Warning 1. Work Zone Warning (Lane Closure & Reduced Speed) 2. School Zone Warning
