·         Link Activity

o      Traffic Volume (VPH: Vehicles per hour) 1 Hour Analysis - The hourly traffic volume anticipated to travel on each link, in units of vehicles per hour.  If a multi-run scenario is selected, traffic volume must be defined for 8 hours.

o      Emission Factor (g/mi) 1 Hour Analysis - The weighted average emission rate of the local vehicle fleet, expressed in terms of grams per mile per vehicle.  Emission rates vary by time of day.  Therefore, if a multi-run scenario is selected, emission factors must be defined for 8 hours.

In this tutorial, this value is the emission factor returned from the Vehicle Design Module for your specified fleet of vehicles.  Enter the same value for all links.
