Abstract

The average emission rate for all drivers for CO2 was 1.31 g/sec for the signal, 0.71 g/sec for the four-way stop, and 1.34 g/sec for the roundabout. Average HC emission rates were 0.34 g/sec for the signal, 0.25 g/sec for the four-way stop, and 0.33 g/sec for the roundabout. Emission rates were highest at the signal for two drivers and highest at the roundabout for 2 drivers. The results demonstrated that none of the types of traffic control were consistently lower for any of the emissions assessed. It was suggested that roundabouts are not necessarily more beneficial in terms of emissions than other types of traffic control. This is an abstract of a paper presented at the 104th AWMA Annual Conference and Exhibition 2011 (Orlando, FL 6/21-24/2011).
