Collision Avoidance System

These simulations to demonstrate how Collision Avoidance System help protect Vulnerable Road Users.
A typical left-turning manoeuvre, with CAS switched off

An articulated heavy goods vehicle (HGV) and a cyclist are simulated to follow their respective path to negotiate the corner. The predicted positions for both the HGV and the cyclist are animated as well. In this animation, HGV keeps its speed even when a potential collision is detected.

A typical left-turning manoeuvre, with CAS switched on

In this case, the HGV brakes the moment a potential collision is detected. The HGV is brought to a stop and the cyclist escapes.

Reconstruction of a real fatal cyclist-HGV accident

Both the cyclist and the HGV start after the traffic light turns green, the HGV goes quite deep into the junction to commence the left-turning manoeuvre, while the cyclist intends to carry straight ahead. The cyclist takes HGV's intention wrongly and the HGV is not able to heed cyclist. Therefore an accident happens inevitably.

Reconstruction of a real fatal cyclist-HGV accident, if the CAS was on

Assuming we had the collision avoidance system (CAS) equipped with the very HGV that caused the accident, this simulation shows the accident could be avoided if we had the CAS intervened HGV's manoeuvre.
