How does it work?
It is a collision warning system, in the event that the vehicle driven is too close to colliding with a parked or moving vehicle ahead. This is done using a sensor that is mounted on the front of the vehicle (e.g., RADAR, LIDAR and/or camera).
These warning systems are useful in alerting the driver to dangerous situations ahead, helping them respond more quickly when the need arises. The type of warning used by the systems varies between vehicles. Some use a flashing light while others use an alarm or vibration sound.
Forward collision warning systems should not be confused with forward collision mitigation systems. Warning systems simply warn the driver when a collision is likely to occur, but do not automatically apply the brakes. It is also important to note that different vehicles have the ability to detect different types of crashes. Some vehicles will only sound the alarm if you are about to collide with another moving vehicle, for example.
- Forward collisions are among the most common types of crashes. Forward collision warning systems are therefore of great benefit, as research has shown that they can substantially reduce the risk and severity of these types of collisions.
- Being a technology that alerts the driver about potentially dangerous situations, a conceptual benefit is that this technology has the ability to increase people’s confidence in continuing to drive safely, even when they are hampered by factors such as aging.
- This technology is designed to warn drivers about possible hazards so that the driver can make the right decisions. Therefore, forward collision mitigation systems are not considered within this technology spectrum.
- It is still a feature mainly present in luxury vehicles, but in combination with other active technologies, it has the potential to become standard equipment and increase its market penetration.
- It is a feature that depends on the attention, dexterity, and good judgment of the driver for its complete effectiveness. At all times, active user surveillance is required.
- The type of system used for forward car detection can influence its use, as camera-based systems are less effective at night than radar-based systems, and can be “blinded” by direct sunlight (e.g., early dawn and late sunset). Likewise, the effectiveness of systems based on cameras and radars can be compromised by the accumulation of snow or ice in front of the sensors.

- Comparison of Experienced and Novice Drivers' Visual and Driving Behaviors during Warned or Unwarned Near-Forward Collisionsby Jordan Navarro on October 14, 2023 at 10:00 am
Forward collision warning systems (FCWSs) monitor the road ahead and warn drivers when the time to collision reaches a certain threshold. Using a driving simulator, this study compared the effects of FCWSs between novice drivers (unlicensed drivers) and experienced drivers (holding a driving license for at least four years) on near-collision events, as well as visual and driving behaviors. The experimental drives lasted about six hours spread over six consecutive weeks. Visual behaviors (e.g.,...
- Adaptive forward collision warning system for hazmat truck drivers: Considering differential driving behavior and risk levelsby Yichang Shao on July 20, 2023 at 10:00 am
The risky driving behavior of hazmat truck drivers is a crucial factor in many severe traffic accidents. In-vehicle Advanced Driving Assistance Systems (ADAS), integrating vehicle active safety and driver assistance technology, has been installed into hazmat trucks aiming to reduce driving risks during emergencies. This paper presents an enhanced dynamic Forward Collision Warning (FCW) model tailored for hazmat truck drivers with different driving characteristics and risk levels. Our objective...
- How can front crash prevention systems address more police-reported crashes in the United States?by David G Kidd on July 5, 2023 at 10:00 am
Government and consumer-information organizations can motivate automakers to address additional crash types through front crash prevention (FCP) testing programs. This study examined the current state of crashes potentially relevant to current and future FCP systems to provide a roadmap for the next crash types that vehicle testing programs in the United States should evaluate. Crash records from 2016 to 2020 were extracted from the Crash Report Sampling System (CRSS) and the Fatality Analysis...
- Characteristics of automatic emergency braking responses in passenger vehicles evaluated in the IIHS front crash prevention programby David G Kidd on June 10, 2023 at 10:00 am
Researchers can estimate the potential safety benefits of front crash prevention (FCP) systems by simulating system performance in rear-end crash scenarios reported to police or captured during naturalistic driving. Data to support assumptions about FCP systems in production vehicles, particularly automatic emergency braking (AEB), are limited. This study used detailed information from the Insurance Institute for Highway Safety's (IIHS's) FCP evaluation to characterize interventions in vehicles...
- Effects of forward collision warning and automatic emergency braking on rear-end crashes involving pickup trucksby Jessica B Cicchino on February 28, 2023 at 11:00 am
OBJECTIVE: Forward collision warning (FCW) and automatic emergency braking (AEB) have found to be effective on cars, SUVs, and large trucks. The objective of this study was to extend prior work and estimate the effects of FCW and AEB on pickups.
- Can the speed limit be used as a surrogate for the striking vehicle's travel speed or delta-V in police-reported rear-end crashes?by David G Kidd on August 5, 2022 at 10:00 am
Objective: A recent study by Kidd (2022) recommended that organizations evaluating front crash prevention (FCP) systems like automatic emergency braking and forward collision warning increase speed differentials in existing test scenarios from 25 mph to 45 mph to make the tests more representative of police-reported rear-end crashes. Kidd used the posted speed limit as a proxy for the striking vehicle's travel speed prior to the crash. The current study used velocity data from event data...
