Integrated Vehicle-Based Safety Systems (IVBSS) Initiative

Goal: Work with industry to accelerate introduction of integrated safety systems into the U.S. vehicle fleet of light vehicles and heavy trucks

Addresses three Crash Types:• Rear End• Road Departure• Lane Change/Merge

42006 ITS World Congress 4

Target Crash Problem

Studies conducted by the U.S. DOT indicate that widespread deployment of an integrated system combining rear-end, lane change and roadway departure crash countermeasures could prevent a significant number of these crashes each year.

52006 ITS World Congress 5

• Forward crash warning (FCW)• Provides warnings to drivers to assist

them in avoiding, or mitigating, crashes with the rear end vehicles traveling in the same direction

Major Program ActivitiesPhase 1: • Integrated System design and development

• Development of functional requirements and performance specifications

• Human Factors/DVI development• Building engineering development vehicles

• Including integrated warning characteristics, high quality DVI, and prototype data acquisition system

• Verification Testing – Objective test procedures

• Independent Evaluation Planning• 12/07: Decision point for Phase 2Phase 2:• Field Operational Test – fleet build, pilot testing• Evaluation of Safety Benefits
