The 2012 and 2035 Volume/Capacity Ratio Maps (PDF) show the level of congestion for Jefferson County and Colorado Department of Transportation (CDOT) roadways. A volume to capacity ratio measures the amount of traffic on a given roadway relative to the amount of traffic the roadway was designed to accommodate.
Congestion levels for this Jefferson County analysis are defined below:
Low congestion - volume/capacity ratio of 0.8 to 0.99
Moderate congestion - volume/capacity ratio of 0.9 to 0.99
Heavy congestion - volume/capacity ratio of 1.0 to 1.29
Severe congestion - volume/capacity ratio of greater than 1.30
