The Highways Research Station of the Madras State Government in Guindy has drawn up fresh designs for some of the traffic islands on Madras city roads and these are being considered by the authorities. The Research Station has been doing considerable work studying traffic problems and other matters connected with the alignment of roads, and furnishing suitable designs for traffic round-abouts. The authorities hope to prepare designs also for junctions at various other points on the National Highways in the city after completing a traffic survey which they propose to conduct shortly.
