Why are some ramp signals operating while others are turned off? Are there different hours?
The purpose of ramp signals is to help regulate freeway traffic flow and merging during periods of intense use. Ramp signals on I-95 in Miami-Dade County will be “demand responsive” – that is, the signals will turn on based on traffic flow. What this means is that signals will typically operate during periods of heavy traffic, such as weekday morning and afternoon commute hours. Ramp signals also may be activated during the “off” hours in the event of an incident on the freeway or for special event traffic.
