No matter how careful a driver of a large machine is, there is always a danger of a collision if their attention is on another complex operation.

Dangerous places at the best of times and most law abiding citizens respect that. However, wreckless or malicious people can leave obstructions that could lead to the de-railing of a train. The LMS detects obstacles on the track up to a range of 75m, and can also detect whether the gates are up or down and can self-inhibit when the train passes the beam. The device is designed for outdoor use with integrated heating and fog correction, as well as warning outputs if the device is being tampered with.

Using a crane to unload cargo from the hold of a ship can be difficult and any collisions with the bridge must be avoided. The LMS outdoor will warn operators if they start to get too close.

Used throughout the UK, these cranes are protected by the LMS outdoor. The main problem is that the driver is so high his visibility is severely restricted. The LMS gives audible warnings if the crane gets too close to another crane or an obstruction on the rails

Avoiding cars colliding would be utopia! However, whilst humans are driving them, then that is a bit of a pipe dream!
The first team to complete the driverless vehicle challenge (DARPA) in the USA, used the LMS to avoid collisions and guide the autonomous vehicle across 131.6 miles in the Mojave Desert.

Not only is the LMS outdoor used for anti-collision, but it is also used as a high-end security device. It has a much lower nuisance alarm level than other devices on the market, so therefore it is especially suited for prisons etc where it can be used for perimeter, area, facade or rooftop protection.
