How does a MOIS work?

The current Moving Off Information Systems in the market use a variety of technologies to detect VRUs in the vehicle’s frontal blind spot.

There are currently a variety of technologies used in today’s market to detect VRUs in the vehicle’s frontal blind spot. These sensor technologies include AI cameras, radar and ultrasonic sensors and are mounted on the front of the vehicle.

The sensors continuously monitor the area in front of the vehicle, particularly the blind spots close to the front.

If the system detects a VRU within the hazardous zone, it alerts the driver through visual (dashboard lights) and/or audible (beeps) warnings.

In the context of London’s Direct Vision Standard regulation, the Progressive Safe System, TfL have specified that:

• The MOIS should activate when a VRU is:
  • Stationary or moving forward between 3 km/h and 5 km/h.
  • Approaching the vehicle from the nearside or offside (i.e., both sides of the vehicle).
  • Traveling in a direction perpendicular to the vehicle’s centre line.
• Additionally, MOIS should provide a warning signal to the driver if there’s a potential collision risk with a VRU meeting the above criteria, when the vehicle is traveling between 0 km/h and 5 km/h.
• The information signal should only be triggered for VRUs whose characteristics, such as speed, trajectory, size, or movement, indicate they are a vulnerable road user.

What are the benefits of a MOIS?

Reduces blind spot collisions:

MOIS helps drivers become aware of pedestrians and cyclists who might be hidden from their direct view, especially when starting off or making low-speed turns.

Improves driver awareness:

Even though MOIS shouldn’t replace the driver’s responsibility to be vigilant, it can serve as a valuable reminder to scan the surroundings and confirm the area is clear before proceeding.

It’s important to note that MOIS is not a substitute for safe driving practices. Drivers should always prioritise defensive driving techniques, like checking mirrors and blind spots, to ensure the safety of themselves and others on the road.

AddSecure provide a MOIS as part of our Progressive Safe System solution in conjunction with the Blind Spot Information System (BSIS), left turn alarm, in-cab driver alert and monitor. To find out more information about this solution, visit here.
