  In this paper, we introduce an open-source model "MOVESTAR" to calculate the
fuel consumption and pollutant emissions of motor vehicles. This model is
developed based on U.S. Environmental Protection Agency's (EPA) Motor Vehicle
Emission Simulator (MOVES), which provides an accurate estimate of vehicle
emissions under a wide range of user-defined conditions. Originally, MOVES
requires users to specify many parameters through its software, including
vehicle types, time periods, geographical areas, pollutants, vehicle operating
characteristics, and road types. In this paper, MOVESTAR is developed as a
simplified version, which only takes the second-by-second vehicle speed data
and vehicle type as inputs. To enable easy integration of this model, its
source code is provided in various languages, including Python, MATLAB and C++.
A case study is introduced in this paper to illustrate the effectiveness of the
model in the development of advanced vehicle technology.
