This paper describes an approach for relating the impact of traffic on ambient carbon monoxide concentrations near signalized intersections by (a) computing the emission profiles due to acceleration and deceleration of queuing vehicles for a range of queue lengths and approach and departure speeds, (b) approximating the profiles by simple by simple step functions based on emissions on the portion of roadway occupied by the queues, (c) adding emission components for cruise and idle modes of vehicle operation, and (d) using the derived emission profiles in a line source dispersion model to estimate ambient CO concentrations at selected receptor sites. Steps for estimating emission profiles have been suggested and applied successfully.
