Abstract :
Light and Safety. Records kept by L. J. Samson, city traffic engineer of Chicago, ill., show a large dividend in safety on the investment for lighting dangerous intersections with sodium-vapor lamps. For the year following the installation of the lamps, in November 1937, as compared with the preceding year, night accidents dropped from 95 to 40, or 58 per cent; the number of persons injured from 43 to 14, or 67 per cent; and property-damage collisions from 61 to 28, or 54 percent.
