The selection process and procurement of right transit bus with fuel and powertrain technology is vital for any cost-effective transit service. There are cities in which conventional diesel fueled bus is used for transit service. It is not always viable to replace the whole or part of the fleet with a vehicle with a different powertrain. Every city are unique in its road type, road grade, service routes, meteorological aspects and traffic population. Since, each of the powertrain technology offers a different combination of advantages and disadvantages, we need to study and analysis each drivetrain technology to find out the best match for our city. There is a variation in transit bus types that are suitable for distinct types of cities, services, and operations. Fuel consumption is directly related to the bus size, engine technology and powertrain. Evaluating fuel consumption correctly, predicting detailed emission for the greenhouse gases and analyzing life cycle costing could be a daunting task and often needs expensive on-board equipment and intricate simulation testing. Lacking this kind of amenities makes it impossible for transit service on a county scale and project level research. In this study, a local database of transit service generated from the well documented database to provide a detailed analysis of fuel consumption, emission and life cycle costing. The integral part of evaluating fuel consumption accurately is to compare test data over a relevant drive cycle. This research also discusses drive cycle and how to select from standard drive cycle for urban city transit network.
