Enter the entrepreneur Mulligan, who is also the president of Suwanee tech company Applied Information. This firm builds this smart signal technology and also deploys it via its Travel Safely app, which can communicate with traffic signals as a smart vehicle would. Mulligan explained this technology in a Gridlock Guy piece on the North Avenue smart corridor two years ago. Applied Information and an army of other tech firms, automakers, and other stakeholders in the technology and transportation industries are using their strengths in the private sector to innovate and then work with the public sector for traffic solutions.

In metro Atlanta, the City of Marietta was the first to deploy Mulligan’s technology and now equips first responders’ vehicles and CobbLinc buses this way. Traffic lights turn green automatically, for example, for a bus that is behind schedule and has five or more people on board, and the city controls that threshold. Traffic lights also go green for fire trucks and med units on emergency calls.
“(The cities using this technology) see that they can deliver better health outcomes by saving heart attack, stroke, accident and opioid victims,” Mulligan explained. Marietta City Manager Bill Bruton told Mulligan the hastened response time is most helpful to those who overdose on opioids, because successfully administering the opioid antidote Narcan is extraordinarily time-critical.
“The data shows that (smart technology) saves about 11 seconds per intersection, and the paramedics fly between five and six intersections on their way to a call.” So the data has shown Mulligan and city planners that response times have decreased by about a minute.
Mulligan calls this a “Day One Application” of his products: They are immediately successful for first responders, before the first civilian smart car ever prevents a crash or before the connected buses alleviate traffic.
125 smart intersections have just gone online in Alpharetta, and the city’s fire trucks are already equipped to trigger these traffic lights. The City of Marietta has continuously grown this technology in its densely populated areas. Atlanta has had the North Avenue smart corridor for more than two years, but now has smart technology on Campbellton Road and is working on it for Martin Luther King Junior Drive. Each of those corridors sees heavy MARTA use, and the city believes connected buses and signals can make big impacts there.
This technology is catching on statewide, in fact, as smart speed limit and school-zone signs and signals dot the entire state. Mulligan said that Georgia truly is on the cutting edge in this realm.
“There is a very robust and progressive culture here that is not prevalent in the rest of the world,” Mulligan said of both the Georgia private- and the public-sector entities with which he has dealt in the past few years.
State officials, including Georgia Lieutenant Governor Geoff Duncan, mingled with stakeholders in the automotive and technological fields at iATL’s recent grand opening. Many chest-pounding events of these are all bark and little bite. But given the sincere interest from cities and automakers and their use of iATL as a testing field for the technology, this wireless wave has some punch. And given that any city that deploys these innovations can nearly guarantee faster emergency-response times means the investment is successful out of the gate.
Mulligan estimated that the cost of the entire connected systems that Alpharetta bought roughly equaled the cost to add an extra lane to one intersection. The answer to building cities is no longer just building the roads.
