ANALYSIS OF ENERGY AND EMISSION BENEFITS OF HYDERABAD METRO RAIL TRANSIT SYSTEM - A VEHICLE AVOIDANCE APPROACH

摘要

Hyderabad introduced Metro rail in the end of 2017 to take some pressure off the road based transport system and provide an alternative mode of transport to the commuters of the city. This paper calculates the change in net energy consumption and emissions due to implementation of the Metro Rail. While, there is saving in energy and emission due to vehicles which are being avoided, the Metro Rail itself adds the total energy consumed and emission due to its operation. In the analysis, various modes of vehicles (two-wheelers, three-wheelers, cars, taxis and buses) and different fuel types (petrol, CNG and diesel) are considered at present and in the future, corresponding to the implementation of various stages of Metro Rail. Among the other pollutants, the CO_2 emission due to vehicles avoided have been compared to the CO_2 emission from the Metro. The authors' finding shows that in the present scenario the energy and emission saving constitutes a very low percentage of the overall energy demand and projected emission. Though, Metro fails to result in significant energy saving and emission reduction it can still contribute significantly in congestion reduction, reducing travel time and exposure to air pollution.
