Analytical Tool for Measuring Emission Impact of Acceleration and Deceleration Lanes
In this study, nonlinear regression models were developed to take into account factors of acceleration or deceleration. To fully capture the dynamics of specific accelerations or decelerations, not only is the acceleration or deceleration of the current time period included in the models as independent variables, but those of previous time periods are also included. In addition, the durations that acceleration or deceleration has been exercised are also included as independent variables. The factor of road grade is considered in the models by adjusting the values of acceleration or deceleration according to the grade. Besides these independent variables, variables representing tractive power are also introduced into the models because they directly determine the amount of emissions that are produced by a vehicle. With this modeling approach, the validation results show that the emission model developed in this study can produce a close match to raw emissions data on both microscopic and macroscopic levels.
