ACC with forward collision warning (FCW) and automatic emergency brake (AEB)Definition
‒ ACC regulates speed and headway (can be turned off)‒ FCW warns, AEB brakes – Wide range of different systems‒ “High speed”
Effect on KSI‒ Affects rear-end collisions and most other collisions with motor vehicles‒ Spare part calls, insurance claims, field/simulator studies, crash statistics‒ Highly inconsistent findings‒ Assumed -5.3 % KSI in passenger cars

Vulnerable road user warning with AEB
Definition‒ Basic: Detects pedestrians in front of the car, AEB brakes‒ Medium: … + cyclists‒ Advanced: … + blind spot warning
Effect on KSI‒ Field/simulator studies, crash statistics: Pedestrian/cyclist – car collisions ‒ Basic: -7 % KSI pedestrians in pedestrian-car crashes‒ Medium: -7 % KSI pedestrians, -7 % KSI cyclists….‒ Advanced: -7 % KSI pedestrians, -8 % KSI cyclists….

Lane departure warning (LDW) / Autonomous lane keepingDefinition
‒ LDW: Warns the driver‒ Autonomous lane keeping: Keeps the lane (in specific situations)
Effect on KSI‒ Crash studies, field/simulator studies, crash statistics‒ LDW: -6.4 % KSI in passenger cars‒ Autonomous lane keeping: -15.8 % KSI in passenger cars

Intelligent speed adaptation (ISA)
Definition‒ Informative: Warns the driver‒ Overridable: Counterforce on the accelerator pedal‒ Mandatory: Non-overridable
Effect on KSI‒ ISA affects speed – Speed affects KSI‒ Informative: -7.5 %; Overridable: -9.3 %; Mandatory: -16.2 % KSI in crashes
with passenger car‒ Involuntary drivers speed more + are less inclined to comply
Too fast!

Alcohol ignition interlock / drug ignition interlockDefinition
‒ Alcolock: Prevents drunk driver from starting the engine‒ Drug ignition interlock: … driver under the influence of drugs ….
Effect on KSI‒ Alcohol/drugs – crash risk‒ Alcolock: -11.1 % KSI in crashes with passenger car‒ Drug ign. interlock: -14.6 % KSI in crashes with passenger car‒ Max effect for most involuntary drivers‒ More drunk/drug driving in older cars
