Intersection Colision Avoidance

IntelliDrive BenefitsDramatically Reduced Fatalities and Injuries

• Greater situational awareness– Your vehicle can “see”

nearby vehicles and knows roadway conditions you can’t see.

• Reduce or even eliminate crashes through– Driver Advisories;– Driver Warnings;– Vehicle Control.

IntelliDrive has the potential to address 82% of the vehicle crash scenarios involving

unimpaired drivers.

IntelliDrive SM BenefitsIncreased Mobility and Environmental Stewardship

• Information-rich environment benefits users and operators of all travel modes.– Travelers have real-time information

on rerouting or “modal shift” options.– System operators have real-time data

to enable better system operations for optimal performance.

– Planners can use data to address system-wide issues.

• Environmental benefits– Reduced stopping/starting at traffic

signals which consumes 3-5 times more fuel than constant driving.

– Nav systems with real time information can reduce fuel consumption by 10.5% over systems without real time traffic data.
