Lighting for walkways shall be as given below:
a) Lighting should illuminate the walkway; lighting fixtures not exceeding a height of 4 m from ground level should be provided.
b) Lighting shall be provided every 20 m to 30m, focusing light not on the car lanes, but on the walkways.
c) A white light source, for example high-pressure sodium, is preferable in city and town centres for the aesthetic effect and for better colour definition, which benefits those with poor sight.
d) White lighting at average 35 to 40 lux is recommended to ensure colour contrast of tactile blocks and to ensure visibility at night to persons with low vision.
e) Light pole may preferably be located within the tree-planting zone.
