Gridlock Guy: Traffic technology spreads, saving opioid victims

iATL recently opened in metro Atlanta with the hope using technology to relieve gridlock

Here are the top 10 cities and the hours their commuters wasted in congestion in 2017: Los Angeles 102 Moscow 91 New York 91 Sao Paulo 86 San Francisco 79 Bogota 75 London 74 Atlanta 70 Paris 69 Miami 64

The first song on CAKE’s 1994 debut album “Motorcade of Generosity” is “Comanche” and repeats this line, “If you want to have cities, you have to build roads.” The line is symbolic, meaning success comes in steps. But in literal practice, the phrase is becoming less true for city developers.

Connected or “smart” vehicles and traffic signs and signals are increasing in number, and Georgia has become a cutting-edge testing ground. With a main goal of decreasing traffic delay, the technology is bucking the traditional paths to gridlock relief.

iATL, the Infrastructure Automotive Technology Lab, just opened two weeks ago off of Haynes Bridge Road just west of GA-400 in Alpharetta. The main room in the brand-new building displays several types of traffic signs and lights on its left wall. Then two long rows of traffic signal boxes, simulating all the types in use around the country, take up the rest of the room. Each box and signal is equipped with wireless radio technology that allows them to communicate with each other — and with smart vehicles.

“It all changed on January the 7th, 2019,” iATL director Bryan Mulligan explained. “The reason being is that the Ford Motor Company announced at C.E.S. that they were doing connected vehicles.”

Ford became the first automaker to commit to making all of its new vehicles connected by 2022. This means that their entire showroom fleets will soon be able to work with traffic signal settings and other radio-equipped smart cars to decrease congestion and the instance of high-risk maneuvers. These cars will not all be self-driving, but they will be able to prompt drivers to make better decisions and move more freely.

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.
