In present work a Delphi study was commissioned to obtain the feedback and suggestions of the experts, having technical backgrounds, such as industrial, scientific, transport administration, engineering academics and engineering studies. The questionnaire was designed including a wide spectrum of different modes of transportation, beginning with bicycles and cycle rickshaws, encompassing all the prevalent modes of automobiles being used and including up to electric and solar powered vehicles. The collected data was analysed using the MATLAB software and the results have been used to estimate and then propose future emission modification factors. It is found that a large majority of experts were in favour of improving and subsidizing the public transportation system, enhancing the traffic management and accelerating the infra-structure projects. The preferences of the experts were given due consideration while proposing the future emission control strategies and making the estimates of the vehicle emissions in the next chapter.
