Congestion and Bottleneck Identification (CBI) Tool Software Download

In a recent study directed by the Federal Highway Administration, congestion identification was one of the primary areas of emphasis. Some of the researchers developed innovations to account for visibility and weather effects on traffic congestion. Other researchers prepared models that filter out congestion caused by traffic signals, to better identify congestion caused by neighboring vehicles. FHWA developed software to identify congestion using new performance measures. The software development effort involved a congestion and bottleneck identification (CBI) tool, containing both numeric and graphical performance measures. The CBI tool was designed to compare and rank traffic bottlenecks in greater detail than existing methods.
