NEW TRAFFIC CONTROL.

1 ADOPTED AT HOME. ILLUMINATED POSTS. A new system of street traffic con--1 trol signals is to be brought into -operation shortly,..which will obviate the necessity of detailing police constables at busy street corners and release them tor more important duties. The system will take the form ol illuminated posts on the edge -of the tootvvalk. The posts will each be 9ft. 6in. in height, and at the top will be three illuminated discs, one underneath the other, indicating “Stop” '(red), “Caution” (amber), and “Go” ■ (green). One post with the three signs will be placed at each of the four corners of a junction, and will automatically' warn oncoming traffic. In addition, there will be white liue-s with the word “Slow” painted on the road surface at a short distance from the road crossing. The discs are so constructed that there will be no necessity to illuminate them artificially in the daytime, but they will be electrically lighted at night. The four posts at any one junction will be electrically controlled from a junction box, and will be so arranged that they can be worked automatically, manually, or by a combination of both means. When controlled automatically', the colours on the two corresponding posts will coincide, the red and green lights being visible alternately for a period of about- seventeen seconds, and in between the two the amber caution liglitwill be illuminated for about three seconds, this being considered a sufficient length of time to warn oncoming traffic to wait until the next signal is seen. The latter signal, of course, might lie either red or green, according to the sequence. The new traffic control has been in operation in Leeds for some months with entire success.
