| Abstract: | Real world driving cycles represent traffic behaviour and it is an
important element of emission model. Although Indian driving cycles have been
developed to test emission and fuel consumption but they are based on constant
speed, acceleration not covering heterogeneous traffic composition. Therefore,
in this study bus driving cycle have been attempted to estimate emission and
fuel consumptions including the changes in the driving characteristic of other
vehicles as well. In this paper driving cycles are derived at Bus Rapid Transit
(BRT) corridor of Delhi
for buses, cars and motorcycles using real world driving data in both
operational and non-operational stretch. The results show that average running
speed of buses in operational corridors are higher. However, due to
introduction of BRT, there was reduction in speed for cars and motorcycles
because of lesser road space availability in contrast to the traffic volume.
Even chances of accidents are lower because of speed reduction. The changed
speed pattern also affect the modal shifting from cars, motorcycles to buses
resulting lower emission along the corridor. In this paper two emission
scenarios are developed by assuming 5% and 10% modal shift of commuter from
cars and motorcycles to buses due to higher operational efficiency in BRT
system. We found, that there was decline of 4% and 9% emission for CO and HC in
comparison to current business as usual scenario, if such a shift is happened.
The results indicate that BRT is environment friendly sustainable
transportation to reduce pollution. This approach well represents real world
traffic behaviour in heterogeneous condition for sustainable transport. |
