TRAFFIC LIGHTS
AUTOMATIC CONTROL
The policeman who directs traffic is gradually being replaced by automatic signals in the main thoroughfares of London. The system was first tried 111 Oxford Street, where lights are installed at each corner. Tho lights are controlled from a central point, and tho frequency of the stoppages, to allow for the cross-stream of traffic, are diminished or in creased, according to the time of the day and' the heaviness of the traffic. J . In other parts of London the authorities are gradually introducing tho automatic electric control. Some ten yards before each crossing is a rib of thick rubber running across the street. Each vehicle which crosses this makoa a registration on an electric apparatus, and when a sufficient number have crossed a certain device changes the green light to amber and then to red. Trafalgar Square, which needed a large number of policemen on point duty, is now controlled by the automatic light system. Though the system costs a good deal for upkeep, the cost is nothing like the cost of wages to a small army of constables.
