Estimating the amount of CO2 emission from probe-car data

A mixed integer programming is formulated for estimating the speed and the acceleration of a vehicle as functions of the time based on the data from a probe-car system. It is assumed that the data from the probe-car system include the statistics (specifically, the maximum, the minimum, and the average) of the speed and the acceleration, respectively, of the vehicle. The estimated functions have the statistics that agree with those measured by the probe-car system. Also, the estimated function of the acceleration is smooth, which agrees with the observation that drivers are less likely to change the acceleration radically. The estimated functions of the speed and the acceleration of a vehicle can be used to estimate the amount of CO2 emission from the vehicle.
