Ramp signaling is a proven technology — new to Central Florida — that will help make merging in the downtown Orlando area smoother and safer.

Drivers entering Interstate 4 (I-4) in both directions between John Young Parkway and Ivanhoe Boulevard will encounter new traffic signals — a red and green light — at the end of their on ramps. By waiting just a few seconds for a green light, drivers will be able to merge with I-4 traffic more efficiently.

Ramp signals reduce stop-and-go traffic at merge points, so they improve drivers’ overall travel times and make merging safer for everyone by reducing crashes.

Ramp signaling is an operational improvement to I-4 that uses a combination of sensors and computers to control the rate at which vehicles merge onto the interstate. The sensors look for gaps in traffic, then the signals let merging drivers know the best time to go. Up to two vehicles can merge during each green light.

Ramp signaling will be used only during times of heavy congestion on I-4. This includes when crashes or other incidents create heavier than normal congestion. When the ramp signals are not active, drivers don’t need to stop, but can safely merge onto I-4.

Ramp signaling is already in use in 23 cities around the country, including Miami and Fort Lauderdale.
