Evaluate bus emissions generated near far-side and near-side stops and potential reductions by ITS: An empirical study

In this paper, we use second-by-second automatic vehicle location data to estimate bus emissions near far-side and near-side stops. We classify the bus running state near a stop into approach, dwell, and departure. A vehicle specific power approach is used to estimate bus emissions for each state. We show that bus emissions generated near stops can be significantly reduced by using certain intelligent transportation systems techniques.

► This study uses case study data from California to estimate bus emissions near far-side and near-side stops.
► GPS data to estimate bus emissions near stops.
► At far-side stops, being stopped produced 100% more emissions in our cases.
