Forward Collision Warning
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.
Pros
- 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.
Cons
- 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.

- How predictive-forward-collision-warning reduces the collision risk of leading vehicle driverby Qiang Fu on January 1, 2025 at 11:00 am
Mixed platoon with a human-driven leading vehicle may be a transition mode prior to the widespread adoption of fully autonomous platoon. Enhancing the driving safety of the leading vehicle driver is crucial for improving the overall operational safety of the mixed platoon. Predictive-Forward-Collision-Warning (PFCW), an emerging technology in transportation, holds promise in mitigating collision risks for drivers by presenting traffic information beyond their immediate visual range. However, the...
- One-pedal or two-pedal: Does the regenerative braking system improve driving safety?by Jun Ma on November 22, 2024 at 11:00 am
Electric vehicles equipped with regenerative braking systems provide drivers a new driving mode, the one-pedal mode, which enables drivers to accelerate and decelerate with the throttle alone. However, there is a lack of systematic research on driving behavior in one-pedal mode, and whether it actually enhances or reduces safety remains to be validated. A driving simulator was used to analyze driving behavior and safety in the one-pedal mode in situations with different urgency level, with the...
- V-FCW: Vector-based forward collision warning algorithm for curved road conflicts using V2X networksby Xiangpeng Cai on November 21, 2024 at 11:00 am
The implementation of advanced driver assistance systems (ADAS) has significantly impacted the prevention of traffic accidents, particularly through the forward collision warning (FCW) algorithm. Nevertheless, traffic conflicts on traffic routes remain a significant issue, since most FCW algorithms cannot accurately determine the distance between the host vehicle (HV) and remote vehicle (RV) on curved roads. Hence, this study proposes a vector-based FCW (V-FCW) algorithm to address the issue of...
- Personalized forward collision warning model with learning from human preferencesby Ning Xie on September 29, 2024 at 10:00 am
The Forward Collision Warning (FCW) system has been widely equipped on vehicles to reduce rear-end crashes, which are considered the most common type of crash. However, existing FCW systems have the problem of low response rates, which restrict their safety improvement effects. This study aims to address this issue by building personalized FCW models based on human risk preferences. First, a warning feedback index ranks the gaps between drivers' risk perceptions and FCW models. Then, reward...
- Assessing advanced driver assistance systems in police vehicles under demanding conditionsby Farzaneh Shahini on September 18, 2024 at 10:00 am
Advanced driver-assistance systems (ADAS) are technologies that can enhance drivers' safety by relieving them from some driving related activities. However, police driving conditions and demands are different from those of civilian drivers. The objective of this study was to assess the impact of ADAS such as forward collision warning (FCW), automatic emergency braking (AEB), and blind spot monitoring (BSM) on police officers' driving performance, workload, and trust in vehicle safety to provide...
