Classification of vehicle emission models.

Classification of emission models	Transportation; model /data	Model parameter	Emission model pattern
Macroscopic emission model	Regional transportation model	Average speed; (macroscopic parameter)	Regional emission (speed correction factor method)
Medium; Emission model	The transport model based on equipment; behavior distribution pattern	Acceleration, speed, and v/c that are based on the traffic facilities; (medium parameter)	The emissions of entire network based on the types of equipment
Microscopic emission model	Microscopic transport mode; Driving cycle mode	Vehicle operation data per second; (microscopic parameter)	Vehicle emissions; per second
