Cancún is rushing a long-promised fix to its traffic signals. City crews and contractors are modernizing equipment at 12 key intersections. They are rolling out a maintenance program that will touch 173 crossings—a scale the municipality hasn’t attempted in years. The work includes new pedestrian signals with audible cues and networked controllers. It also involves fresh geometry at a high-conflict junction on Avenida Huayacán. Officials say the goal is simple: safer, smoother trips for drivers and people on foot in a city with rising crashes.
Cancún traffic lights
Mayor Ana Paty Peralta this week supervised the Huayacán–Avenida 135–Avenida Colegios project. It is part of Benito Juárez’s “Estrategia Integral de Movilidad.” The city describes that site as a whole “ordenamiento vial” with new signals tied into the monitoring center. It includes ramps, markings, and bollards—funded through participatory budgeting with a 5.9-million-peso allocation.
Beyond that flagship corner, City Hall and local outlets confirm the broader push. Twelve strategic intersections are getting new vehicle and pedestrian heads with audible walk indications. They also receive ATC-class traffic controllers for coordinated timing and remote management. In parallel, crews are conducting preventive work across 173 signalized crossings citywide.
ATC controllers are an open-architecture standard used in modern signal systems. They support adaptive timing, data collection, and centralized adjustments—tools cities use to cut delays and respond to incidents.
What will change on the street
The city says its maintenance team is cleaning cabinets and lenses. They are replacing damaged heads and wiring and re-synchronizing timings based on peak and off-peak counts to improve progression. Officials estimate the program is about 20% complete and is scheduled through February 2026. Each crossing receives preventive service twice a year and corrective attention after outages or storms.
While Huayacán draws headlines, Cancún has been phasing upgrades since at least late 2023. It mapped out an initial slate of downtown junctions—Avenidas Cobá, Xcaret, Tulum, Kabah, and Bonampak among them. Emphasis was placed on “cruces seguros” with tactile paving, ramps, and audible signals.
Why it matters now
Crashes have become a pressing issue. Local records point to 2,717 traffic incidents in the first half of 2025, up roughly 65% versus the same period in 2024. Public-service vehicles are involved in a notable share. The city also closed 2024 with about 1,700 crashes and ~38 deaths, according to tallies reported by regional media. Pedestrian risk is acute: by early August 2025, Quintana Roo accounted for about half of the peninsula’s pedestrian collisions. Those figures aren’t perfect—they pull from police and media logs—but the trend is hard to ignore.
Mexico’s General Law on Mobility and Road Safety puts the person at the center of policy. It urges authorities to design for vulnerable users. National manuals recommend accessible crossings, including audible pedestrian indications. The choices Cancún is making—audible heads, safer geometry, curb ramps, system-wide maintenance—track with that legal framework and best practices for urban streets.
What to watch
The city’s own releases tout “technology of the latest generation” and the “largest public-works budget” in its history. The test will be in daily operations: Does the corridor actually coordinate the new controllers? Do audible cues work across the network? Does maintenance keep pace during hurricane season, and do crash patterns fall at the upgraded sites? We will also be watching for the published list of the 12 intersections and any expansion beyond the initial program through 2026.
