Two wheelers utility ratio is rapidly growing with every year in the Asian geographical zones and it also increases the environmental burden. This research work, extracts the data from two scooter type vehicles of different makes on the outskirts of a city in India, during less traffic hours. It identifies six key variables (engine volume (cc), dead weight of vehicle (kg), pneumatic pressure in the tyres, manufactured year, operating speed of vehicle during experimental trials, number of permissible passengers to travel) which can influence the outcome (mileage of vehicle). The methodology utilized in this article is response surface methodology with an objective of maximizing the outcome. The results are inferred from two graphical plots namely: Contour plot and a surface plot. © TJPRC Pvt. Ltd.
