A cost effective system for Railway Level Crossing Protection 20 Salient Features - What the system does Train Approach Warning for road users at Level Crossings in the form of Audio Visual indication Detection of obstruction by road vehicle at level crossing Detection of Gate condition whether it is OPEN or CLOSED? Advance audio visual information to the train crew regarding the condition of the gate as detected by the Gate ACD.

A cost effective system for Railway Level Crossing Protection 21 Gate protection system CAN NOT Prevent a Train Collision when… The Train is a NON ACD Train or Gate is not provided with Gate ACD – ACD functions by reacting to another ACD, as such if one of the two identities is not provided with ACD, the protection against collision will be missing Adequate braking distance at that speed is not available when a dangerous collision-like situation arises suddenly – However, severity of the collision would be reduced as a function of the reaction time
