PREVENTING PASSENGERS BEING CAUGHT BY DOORS

This article describes a new safety device, being fitted to nearly 3,000 London buses, in an attempt to prevent elderly passengers from being caught in the exit doors of buses when they move off. A pressure-sensitive pneumatic device, made by Wilfred Overton of Wednesbury, England, was selected from several possible alternatives. It consists of: (1) a new single door cylinder; (2) new operating rods; (3) new door leaf leading edge rubbers; (4) new diaphragm valve; (5) new micro-valve; (6) piping where required; (7) an electrical one-shot timer. With this design, the doors will open automatically if the door is obstructed, and they will not close again until the driver has again operated the door close button; the doors otherwise operate normally. The new door protection equipment will be fitted to all buses with centre-exit doors by 1993, when legislation will come into force that compels the fitting of such devices to buses of this type. These devices are part of a comprehensive programme to make London's buses safer for old and disabled people by equipping a range of safety features. (TRRL)
