  1. Cooperative Intersection Collision Avoidance SystemsInitiative Mike Schagrin ITS Joint Program Office U.S. Department of Transportation

  2. Why The Concern About Intersections • In 2003, approximately: • 9500 FATALITIES • 1,300,000 INJURIES • 2,600,000 CRASHES • Cost to society  $100 Billion

  3. Intersection Problem Areas Being Addressed • Gap assistance • Stop sign and signal violations • Left turn across path of on-coming traffic • Stop sign movement assist

  4. Accident Causal Factors • Impaired drivers • Aggressive drivers • Inexperienced / Elderly drivers • Obstructed vision (limited sight lines) • Other (Presence of peds, bicyclers, poor weather, etc.)

  5. CICAS Program Goals • To develop and demonstrate cooperative intersection collision avoidance systems • To assess the value and acceptance of cooperative collision avoidance systems • To develop and provide tools to support industry deployments

  7. CICAS Concepts

  8. Cooperative Violation Countermeasure Concepts • The basic capability is for the vehicle to provide stop sign and traffic signal violation warnings • The intersection could provide an infrastructure based countermeasure (e.g., adjust signal timing) resulting from the vehicle sending a warning notification • The vehicle could exert some type of vehicular control countermeasure

  9. Geometric Map • Signal Controller Info • Differential Correction • Road Surface Conditions Current phase Time to phase change Roadside Unit Vehicle System • DSRC • Processor • DGPS • Intersection Map • DSRC • Safety Processor • GPS • Vehicle Sensors Infrastructure to Vehicle Cooperative Violation Countermeasure Scenario • Driver Vehicle Interface (DVI) • Driver Vehicle Interface (DVI) • Driver Vehicle Interface (DVI)

  10. Signal Violation Warning: Vehicle Approaching Example Scenario

  11. Geometric Map • Signal Controller Info • Differential Correction • Road Surface Conditions Signal timing adjustments Roadside Unit Vehicle System • DSRC • Processor • DGPS • Intersection Map • DSRC • Safety Processor • GPS • Vehicle Sensors • Driver Vehicle Interface (DVI) Infrastructure to Vehicle Vehicle to Infrastructure • Alert issued • Dynamic Info Cooperative Violation Countermeasure Scenario Current phase Time to phase change

  12. Gap Assist Countermeasure Concept • Gap assist builds upon the violation concepts and technologies and adds stop sign and left turn gap assistance • Countermeasures include both in-vehicle and infrastructure-based warnings • Vulnerable road users such as pedestrians and bicyclists are addressed

  13. Dynamic Intersection Mapping • Geometric Map • Signal Controller Info Roadside Unit Vehicle System • DSRC • Processor • DGPS • Intersection Map • DSRC • Safety Processor • GPS • Vehicle Sensors • DVI Vehicle to Infrastructure • Alert issued • Dynamic Info Intersection Sensors Gap Assist Countermeasure Scenario • Dynamic Objects • Geometric Map • Signal Controller Info • Differential Correction • Road Surface Conditions Infrastructure to Vehicle • Sensor Fusion

  14. Dynamic Mapping Example

  15. Dynamic Intersection Mapping • Geometric Map • Signal Controller Info Roadside Unit Vehicle System • DSRC • Processor • DGPS • Intersection Map • DSRC • Safety Processor • GPS • Vehicle Sensors • DVI Vehicle to Infrastructure • Alert issued • Dynamic Info Gap Assist Countermeasure Scenario • Dynamic Objects • Geometric Map • Signal Controller Info • Differential Correction • Road Surface Conditions Infrastructure to Vehicle • Sensor Fusion • DVI (gap assist) Intersection Sensors

  16. Vehicle-to-Vehicle Communications Research • Research effort, specifically examining the creation of a dynamic intersection mapping capability by vehicle to vehicle communications • Implementation of such a system would require significant DSRC market penetration and therefore is not envisioned as a near term deployment option • Such a system could extend capability to both uninstrumented intersections and other non-intersection applications
