Traffic Management

Ramp Signals

Ramp Signals have been activated along Interstate 95 (I-95) in Miami-Dade County and are making merging onto the highway easier and safer. Phase 1A of the Ramp Signaling System is located along the northbound entrance points from NW 62nd Street north to NW 167th Street on I-95. Phase 1B of the Ramp Signaling System added signals along southbound entrance points from Ives Dairy Road to NW 62nd Street, as well as two more on I-95's northbound side (at Miami Gardens Drive and Ives Dairy Road).

Ramp Signals are improving traffic flow by controlling the rate at which vehicles enter the highway. The signals are traffic control devices that alternate from red to green lights to ensure that vehicles enter the mainline in a spaced and steady manner. They are designed to improve the merging process for motorists along the highway.

When drivers merge onto the interstate in a controlled manner, the corridor can accommodate more vehicles per hour, helping to maximize the efficiency of the existing roadway network. Regulating ramp traffic improves mobility, which reduces congestion and decreases the incidence of crashes along the highway.

The Ramp Signaling System is part of a series of traffic management initiatives that uses Intelligent Transportation Systems (ITS) technologies to improve highway safety and operations. It's the first of its kind in Florida, and along with the 95 Express, is providing motorists with real-time solutions to the problem of traffic congestion.

Traffic managers at the SunGuide® Transportation Management Center (TMC) activate the Ramp Signals during typical times of heavy highway use, such as weekday rush-hour periods. However, they may also activate the signals in the case of a traffic incident or special event that may impact regular highway operations. Ramp signals operate based on real-time traffic conditions, and depending on the marked signs on each ramp, will allow one or two vehicles to merge onto the highway per green light. Advanced warning signs will flash to alert motorists when the signals are turned on.

How Does Ramp Signaling Work?

1. When the signal is red: Motorists should pull up to the marked white line on the pavement before the "Stop Here on Red" sign to activate the ramp meter light.


2. When the signal light turns green: One or two vehicles, as indicated by the signage on the ramp, should proceed and merge onto the interstate.


3. Motorists should remain patient. A short wait on the ramp will help reduce travel times and improve the overall commute along the mainline.
