“The space at a road junction over which traffic is not allowed to move is known as a traffic island”
The arrangements at road junctions in the form of islands serve the following five objects:
- The efficiency of traffic handling is increased
- There is segregation of traffic in proper channels as they serve as guide to driver to negotiating the junctions
- The traffic island serves as shelter for pedestrians crossing the roads.
- The vehicles are compelled to move in one direction only and separate strips across the roads are provided for the crossing of pedestrians. Thus the chances of accidents are reduced
- They provide the proper place for the installation of traffic signs and other controlling devices
