Research Idea Scope
The way one drives has an impact on the instantaneous and total emissions produced for a given trip. Driving style has an impact on microscopic (second by second) vehicle activities and hence vehicular emissions and fuel consumption. To understand the correlation between emissions and driving style, we need to quantify and measure vehicle (or driver) activity at a higher precision. This may require us to measure the applied force associated with brake pedal and gas pedal use and their corresponding distributions.
To study the effect of driver style, different drivers can be chosen from a range of age and places in the country. On-road emissions data may to be collected on a second by microscopic level in synchronization with brake and gas pedal along with vehicle and engine rpm. The correlation between different driving parameters and emissions can be studied and emissions factors corresponding to defined driving style can be developed.

Urgency and Payoff
The study would give a better understanding of the impact of driving style on emissions. With extreme events like hard acceleration (prolonged as in case of freeway on-ramps) and high jerk (rate of change of acceleration), emissions are expected to rise since high amount of fuel is injected into the engine system within a small duration of time. Incorporating these events in the emissions model is likely to improve estimates for the emissions rates.
