The signals work by communicating directly with buses, said Mark Nogaki, senior vice president for sales for Econolite, the company that's installing the system. The system for the entire county will cost around $150 million, Gimenez said. The mayor and Alice Bravo, the county's Director of the Department of Public Transportation and Public Works, noted that the traffic signal technology decreases bus travel time along the entire South Dade busway by about 15 minutes.

'All the signals in Miami-Dade County in the very near future will be smart,' Gimenez said, 'which should help all commuters in Miami-Dade County to get to and from where they want to go faster.' But Miami-Dade officials plan to expand it to other thoroughfares-including U.S. The South Dade Transitway Corridor is the only bus route that currently has the system.

The system increases the number of green lights for buses along the corridor and reduces wait times during red lights. Miami-Dade County Mayor Carlos Gimenez and other officials rode an express bus along the South Dade Transitway Corridor on Tuesday morning to test new smart traffic priority signals meant to speed up public and private transit throughout the county.
