Abstract:

Ramp signaling is a relatively low-cost traffic management strategy that aims to improve the flow of

traffic by controlling the rate at which vehicles enter the freeway. While studies have shown that ramp

signaling helps to alleviate traffic congestion and improve traffic safety, not all freeway locations are

suitable for ramp signaling. Guidelines are needed to help determine the suitability of freeway

locations for ramp signaling. Proper evaluation of potential locations in accord with these guidelines

requires the use of data sets currently maintained separately by various FDOT offices. This project

identified and evaluated the existing ramp signaling guidelines from 12 states in the U.S., four other

countries, and three independent research organizations. It then selected a set of guidelines for Florida

applications considering the availability of data for evaluation and the experiences gained from the

Interstate 95 ramp signaling project in Miami-Dade County, Florida. A web-based Geographic

Information System (GIS) was then developed to automate, to the extent possible, the process of

evaluating sites for potential ramp signaling on the basis of the selected guidelines. A major component

of the system is a central database that integrates five independent data sets from FDOT, including

roadway inventory, detector data (including volume, speed, and occupancy), traffic counts, police crash

records, and SunGuide incident records. The system greatly reduces the data acquisition effort, which

is often the most time-consuming part of a project. The system can also be used as a tool for general

data retrieval and serve as a platform for other applications. Several enhancements were recommended

to further improve the system, including adding more data with additional details and additional

visualization and reporting functions.
