Transportation has been one of the largest sources of air pollution produced by human activity in the United States; this calls for the development of innovative technologies, such as renewable energy, ecological driving, and connected vehicles. Based on the United States Environmental Protection Agency’s (EPA) newly released emission model, MOVES, an unstable speed profile and excessive acceleration may greatly affect Vehicle Specific Power (VSP) and the Operation Mode Identification (OMID) distributions, which will yield higher emission estimations. The Vehicle to Infrastructure (roadside) (V2I) communication technology is capable of improving driving performance, in terms of smooth speeds and acceleration rates. In this paper, the impacts of the V2I system on vehicle emissions were explored. The V2I technology was employed to provide audio messages to drivers who are approaching intersections in the situations of sun glare and work zones. Impacts on speed and acceleration rates, as well as VSP, OMID distributions and resulted air pollution emitted from vehicles with and without the V2I system, were analyzed through simulated driving tests. The results illustrate that the V2I system can not only improve safety, but also mitigate emitted air pollution.
