Abstract:The Florida Department of Transportation (FDOT) District One developed the Congestion Management Process
(CMP) system to prioritize low-cost, near-term highway improvements on the Strategic Intermodal System (SIS).
The existing CMP system is designed to screen and prioritize all project locations based on seven performance
measures that were adopted from FDOT’s Strategic Investment Tool (SIT). The system also uses a simple scoring
method to prioritize project locations. Since the development of the CMP in 2009, a number of new developments
have taken place, including, but not limited to, the development of the 2060 Florida Transportation Plan (FTP), the
publication of the Highway Safety Manual (HSM), and a new emphasis on freight transportation for economic
development. At the same time, more advanced methods for identifying improvement locations and ranking projects
have also become available. Accordingly, the main objective of this project is to research and update the existing
performance measures and the project prioritization method in the CMP to better reflect the current conditions and
strategic goals of FDOT. A second objective of the project is to develop visual mapping tools in the system.
The final updated list of performance measures includes number of excess fatalities, number of excess injuries,
volume-to-capacity ratio, average annual daily traffic (AADT) per lane, truck volume per lane, truck percent, and
delay. The Analytic Network Process (ANP), an advanced multi-criteria decision-making technique, is implemented
to prioritize highway project locations. Unlike the simple scoring method, the ANP does not give undue weight to a
specific performance measure, and it can account for the interdependencies that usually exist in the performance
measures. Furthermore, the ANP facilitates pairwise comparison of the project locations with respect to each of the
performance measures. The new updated CMP system calculates the performance measures and implements the
ANP approach to prioritize roadway segments. The system also has the capability to create thematic maps of
performance measures and other input variables.
