Headway Monitoring & Warning (HMW)

Why We Need It

Following too closely is one of the main causes of rear-end collisions and is even more dangerous in bad weather conditions. Many drivers underestimate the amount of time needed to stop safely.

How It Works

HMW constantly monitors the distance, in seconds, to the vehicle ahead. An alert is issued if the distance becomes unsafe, according to the fleet's predefined threshold.
