co_hot_spots

Theme keywords: environment, Hot Spots, CO, Carbon Monoxide
Abstract: Carbon Monoxide "hot spot" locations on road segements analyzed for the Baseline Data Report. A "hot spot" is a localized concentrations of carbon monoxide from vehicle exhaust, typically associated with idling vehicles at roadway intersections. It is often a function of vehicle idling time at roadway intersections, which is an indicator of roadway congrestion.

Lineage:
Process step:
Process description:
BDR 3-9: "To identify the potential areas of concentration (hot spots) for carbon monoxide within the County, selected roadway segments from the BDR were modeled with the CALINE4 model using vehicular emission factors obtained from the EMFAC2002 (version 2.2) emission rate program.  Intersection traffic data was unavailable for this analysis.  Consequently, this analysis identifies CO hot spots for selected roadway segments within the County."
BDR 3-4: "Carbon monoxide (CO) modeling was performed for existing conditions using traffic data prepared by the project traffic engineers, Fehr & Peers.  CO modeling was conducted using peak-hour traffic volumes.  Intersection peak-hour traffic volumes were not available for this analysis.  Consequently, the analysis of CO concentrations (hot spots) was conducted using roadway segment data provided by the project traffic engineers.
