Career Path From Engineer To Director
Warren Abadie grew from an engineer aide to Director of Traffic, Roads and Bridges after graduating UL Lafayette in 2003.
He credits a professor's advice that a first job can determine your career and found traffic signals a natural fit for his electrical/computer background.

Signals Operate As A Network
Lafayette maintains roughly 190 traffic signals, many under state agreements and connected via LUS fiber to a central server.
The signals run as a network so cycle lengths sync across corridors, prioritizing main streets over minor approaches.

Three-Way Tradeoff In Traffic Engineering
Traffic engineering balances capacity, convenience, and safety, and none can be fully prioritized without trade-offs.
Roundabouts often satisfy all three goals, improving safety, efficiency, and mobility including U-turns.

Today we welcome Warren Abadie, Director of Traffic, Roads and Bridges for Lafayette Consolidated Government (LCG). A Lafayette native, Warren has spent his entire career with LCG, steadily rising through the ranks after graduating from UL Lafayette in 2003 with a degree in electrical engineering (computer option). He started as an engineer aide, moved on to traffic maintenance supervisor, traffic signal/system engineer, and city-parish transportation engineer before being appointed director in 2020.
“I affectionately refer to myself as the director of misery and unhappiness,” Warren joked, but his love for his job is clear. He explained that a professor once told him, “Your first job will determine your whole career,” and in his case, that proved true. His engineering background in coding and electrical systems naturally aligned with his first promotion into traffic signals.
Managing 190 Traffic Signals Across the City
Warren oversees a vast system of about 190 traffic signals, many of which LCG maintains through agreements with the state.
He explained how the signal network functions:
“If you’re on a minor street at a major street, it’s going to feel like the signal is taking forever. A minute in your car feels more like five minutes. But we run the system as a network. All the signals on Pinhook have to have the same cycle length… so there’s some inefficiencies there. But the main street always takes precedence.”
With a central server syncing up internal clocks, Warren and his team can monitor complaints in real time, using traffic cameras and logs to identify problems, often adjusting signals remotely:
“We’re always tinkering. We’re always changing. We’re always trying to make 10 pounds of fluff fit in a 5-pound bag.”
Balancing Capacity, Convenience, and Safety
Warren described the essence of traffic engineering as a balancing act:
“Traffic engineering is a balance of three things. Capacity. Convenience. And safety. If safety was first, your car wouldn’t go more than five miles an hour… If it was all about convenience, there’d be no pavement markings on the road. And if it was all about capacity, I wouldn’t allow left turns on signals.”
This balance is one reason he strongly supports roundabouts, which check all three boxes by being safer, more efficient, and accommodating U-turns. He acknowledged, however, that roundabouts are more difficult to design and build, and some—like the Ridge Road and Rue de Belier roundabout—are already over capacity, with plans in place for upgrades.
Traffic Growth and New Projects
“Traffic is a sign of economic activity and growth,” Warren noted, pointing out Lafayette is one of the few parishes in Louisiana still growing. He listed several new roundabout projects in the works, including:
Broussard and Robley
West Broussard and Duhon (near Acadian Village)
Ridge and Domingue Road
Rue de Belier and Ridge (expansion to multi-lane)
Vincent Road at E. Broussard
LA 92 and East Broussard (toward Milton)
Safety, Motorcycles, and Crash Data
As a father, Warren is deeply concerned about motorcycles:
“Don’t let anybody you love drive a motorcycle because your target value is just too small and the margin for error is just way too small. It’s exciting, but the reality is there’s just not any room for error.”
His department continually analyzes crash data and works to balance safety with traffic flow, noting that signals reduce deadly right-angle crashes but often lead to an increase in rear-end crashes—generally less severe.
Road Repairs and Infrastructure Challenges
Road work is another part of Warren’s responsibility, and he was candid about the frustrations drivers feel:
“Everything we do day to day requires the use of that system. Generally, the roads are already congested. Now I got to fix it and make them more congested. It’s not something we take lightly.”
He explained the complexity of concrete street repairs and the overlapping roles of utilities, drainage, and road crews: “It’s a monumental task, maintaining all the infrastructure that makes life life. It’s not intentional. We do the best to get out of there. It’s not fun being there… a bulletproof vest won’t stop a car.”
Public Transit: Challenges and Innovations
Warren also oversees transit services, managing ten buses that must cover the entire city. With more than 600 bus stops, many located on open-ditch roadways without sidewalks, he emphasized the pressing need for bus shelters.
He shared his excitement about a new pilot program being considered in the LCG budget:
“Instead of having big buses run everywhere, have more of a micro-transit system, more like an Uber level. A lot more stops could pick you up closer to your house and drop you off closer to the destination. For a suburban city like Lafayette, that has the potential to be a game changer.”
The fare structure would remain affordable, he added: $1 per ride or $25 for an annual pass.
Artificial Intelligence and Smarter Signals
AI is already reshaping Lafayette’s traffic management. Warren explained the evolution from wire loops to video detection, to wireless magnetometers, and now back to advanced AI-powered video systems:
“The AI engines they have now can actually identify if it’s a car, a truck, a motorcycle, a pedestrian. There’s also AI intelligence about near misses. There are a lot of exciting traffic operational advancements going to an AI-based camera system. We are currently in the process of installing those.”
Bikes, Pedestrians, and Complete Streets
LCG is also working on bike lanes and multi-use paths built to a higher grade and separated from vehicles. Warren said these will serve both serious cyclists and those who rely on bicycles for transportation:
“No matter what level of user you are, you would feel comfortable—whether you’re the people I call spandex warriors, or the people that ride their bikes everywhere.”
A Life of Service and Family
“Not everybody gets to come into work and say what I do affects hundreds of thousands of people. One of the inspiring things about what I do is I never have to explain to anybody why we do what we do at LCG. They just know. We live here too.”
Outside of work, Warren and his wife are raising four children. He admitted he hasn’t yet figured out his hobbies now that his kids are getting older, though he’s excited for football season and enjoys “nerding out” on technical projects.
For anyone with transportation-related issues such as road hazards or concerns, Warren emphasized that 311 is the best place to start. “Whatever issue you have, you’ll get to the right person. For non-emergencies, 311 is the place to go.”
Warren Abadie’s career shows how one person’s dedication to public service can touch the daily lives of hundreds of thousands of Lafayette residents. From roads to signals, buses to bike paths, his work blends engineering, innovation, and a genuine love for his community.
