IntelliDrive SM Connectivity and the Future of Surface Transportation

1. IntelliDriveSMConnectivity and the Future of Surface Transportation Ray Krammes FHWA Office of Safety RD&T U.S. Department of Transportation AASHTO SCOHTS Meeting Salt Lake City, UT April 29, 2010

2. Safety • 40,000 deaths/year • 6,000,000 crashes/year • Leading cause of death for ages 4 to 34 Mobility • 4,200,000,000 hours of travel delay • $80,000,000,000 cost of urban congestion Environment • 2,900,000,000 gallons of wasted fuel The Problem!!!

3. It’s All About Connectivity “The Network” Opportunity for Innovation E-payment • Real Time Network Data Signal Phase and Timing • Situation Relevant Information Safety Messages Probe Data Instrumented Roadside

4. Intersection Collision Avoidance Work Zone Notification Opportunity for Safer Driving • Greater situational awareness, i.e., your vehicle can “see” nearby vehicles and knows roadway conditions you can’t see • Avoid crashes thru: • Driver Advisories • Driver Warnings • Focus is DSRC 5.9 GHz • Communication can be to or from vehicle (V2V), infrastructure (V2I), and/or nomadic devices (V2D)

5. Infrastructure Component Infrastructure-based systems can serve as starting point for IntelliDriveSM applications, offering immediate benefits is some cases Many infrastructure-based ITS technologies are already in use or under development to enhance safety Variable speed limits Adaptive signal timing systems Speed-activated curve warning systems Cooperative intersection collision avoidance systems (CICAS)

6. CICAS—Stop Sign Assist • Problem: Drivers either do not see or underestimate speed of approaching traffic while waiting at rural two-way stop-controlled intersection. • Solution: Infrastructure-based sign provide information on “unsafe” gaps based trajectories of approaching vehicles estimated from roadside sensors • Status: • Piloted in 2008 with good results • 3-year field operational testing at 3 intersections In this example:--Mainline traffic approaching from the left is at least 7.5 sec, but less than 11.5 sec away.--Mainline traffic approaching from the right is less than 7.5 sec away.

7. CICAS—Signalized Left Turn Assist • Problem: drivers misjudge gaps in approaching traffic when making left turn on permissive green • Solution: monitor gaps in oncoming through traffic and warn turning driver of “unsafe” gaps • Status: under development

8. V2I Safety Plan • Track 1 – Applications Analysis • Selection of safety applications (Sept-Oct 2010) • Track 2 – Prototype Applications • Field Operational Test (FOT) “go/no-go” decision (mid-2012) • Track 3 – Communications, Mapping, and Positioning • Test and evaluate SPaT, issue SPaT policy guidance (mid-2013) • Test and evaluate mapping and positioning solutions • Test and evaluate communication requirements • Track 4 – Benefits Assessment • Perform FOTs based on selected safety applications (2013-2014) • Track 5 – Deployment Planning • Development of toolbox for practitioners and Public Agency Guidelines (2014)

9. Some of the major items: Industry adopted standards for national interoperability Security Scalability Financing model Deployment scenario Governance structure Quantifying benefits Challenges 9
