CHARACTERIZATION OF WASHINGTON, D.C., CARBON MONOXIDE PROBLEM

Relationships between traffic, vehicle emissions, and carbon monoxide (CO) levels within the Washington, D.C., area are analyzed using the revised CO Hot Spot Guidelines and supplementary computer models. As such, the report provides a demonstration of the revised CO Hot Spot Guidelines, as well as a first level analysis of potential CO problems in the Washington, D.C. area. Three levels of analysis are described: (1) areawide screening of all signalized intersections, (2) hot spot verification at 29 selected locations, and (3) comparison of computer modeling results with ambient data. Data requirements and resource needs are identified for each level of analysis. Annotated instruction sheets, in addition to all tables and graphs used in the calculations, are provided. A preliminary review of the data revealed that the existing data base for the Washington, D.C., area was inadequate for developing and testing techniques for relating changes in VMT and/or vehicle emissions to changes in ambient CO levels.
