Road Classification Based Energy Efficient Design and its Validation for Indian Roads

Abstract

Road lighting consumes a significant portion of global electricity. A good road lighting design ensures the fulfilment of visual requirements with optimized design. The initial step for a good road lighting design is to identify the exact lighting class of the concerned road. The existing Indian Road lighting Standard IS: 1944, 1970 is not so well defined with respect to the modern Indian roads. It demands a specific model for classifying any Indian road. This paper focuses towards the validation of a proposed model, which is a modified mathematical model as recommended by CIE: 115, 2010 for classifying the exact lighting category of the Indian roads. This paper also highlights the scope of energy saving by changing the design according to the changed lighting class during different traffic hours in night. Some innovative design is also proposed for a new road based on the proposed classification methodology.
