Fix the friction first — and own the problem

By Antonio Calleja

Iloilo’s traffic is not the problem. How it’s managed is.

That sounds harsh, I know. But go stand on any major corridor around 5:30 p.m. and just watch. A four-lane road quietly turns into three because vehicles are parked along the curb. PUVs stop wherever it suits the driver, not where it causes the least disruption. Cars nose into intersections and block cross traffic. Sidewalks get squeezed, forcing pedestrians onto the road. And along commercial strips, vehicles reverse straight into moving traffic just to pull out of designated parking slots.

Then everybody wonders why it all grinds to a halt. There is nothing mysterious about this. It is purely mechanical.

Traffic engineers have a term for it — capacity suppression. When lanes get intermittently blocked, when parking maneuvers interrupt flow, when signals are poorly coordinated, a road simply stops functioning at the capacity it was designed for. A corridor that should handle 2,000 vehicles per hour might only push through 1,400. Those missing 600 vehicles per hour do not vanish. They become queues, spillback, and mounting frustration.

And frustration, given enough time, hardens into judgment. The most dangerous phrase making the rounds in Iloilo right now is not “traffic is bad.” It is this: “The city doesn’t know what it’s doing.”

That perception is not forming because Iloilo is growing. Growth congestion, people understand. You expect some slowdown when a city is doing well.

It is forming because so much of what motorists experience day to day feels preventable.

If cars are reversing into live lanes during rush hour because the parking layout allows it — that is not destiny. If intersections stay blocked because enforcement comes and goes — that is not fate. If traffic signals are mistimed and out of sync — that is not some unavoidable byproduct of development.

That is management. Or the lack of it.

Before we start redirecting frustration toward national agencies, let us get the institutional roles straight. The Land Transportation Office registers vehicles and issues licenses. It shapes how many vehicles are legally on the road. What it does not do is time Iloilo’s traffic signals. It does not design curbside parking layouts. And it certainly does not decide whether no-stopping zones near intersections actually get enforced.

Day-to-day traffic performance is overwhelmingly a local affair. If we pin the blame on vehicle growth alone, we let ourselves off the hook for the things we can actually fix.

Yes, Iloilo is expanding. Yes, vehicle registrations keep climbing. Yes, long-term infrastructure upgrades will eventually become necessary. But here is the uncomfortable part: pouring more asphalt into a poorly managed system does not solve congestion. It just spreads it around.

Think about it. If curb disorder and weak signal coordination are already eating up 20 to 30 percent of effective capacity on major corridors, what happens when you funnel even more traffic into that same friction-heavy system? The inefficiency does not stay flat. It scales.

Sequencing matters. Before building another road, fix the one we already have.

That means enforcing clear zones at least 30 meters from intersections — no selective exemptions. It means eliminating or redesigning reverse-out parking on high-volume arterials during peak hours. It means formalizing PUV loading bays and physically protecting them, instead of tolerating stops that block entire lanes. It means reclaiming sidewalks so pedestrians stop becoming moving obstacles. And it means conducting a corridor-wide signal audit and synchronizing intersections based on actual, real-world data — not timing plans that may have been outdated years ago.

None of this is glamorous. Nobody is cutting ribbons for a synchronized signal network. There will be no groundbreaking ceremony for a cleared intersection box. But these kinds of reforms could realistically cut peak travel times by 15 to 25 percent within a year on near-saturated corridors.

And here is the question worth sitting with: if that much improvement is achievable without a single new road, what does that tell us about how much capacity we are currently throwing away?

Traffic is not just about getting from point A to point B. It reflects institutional seriousness — whether public space is treated as scarce capital or as informal real estate. Whether rules get applied consistently or relaxed depending on who is looking.

Right now, congestion in Iloilo is sending a message. Not that the city is growing too fast. But that operational discipline has not kept pace with ambition.

Owning the problem is the first step toward solving it. Blaming vehicle growth is easier. Announcing new projects gets more attention. But competence shows in how well the basics are managed.

Fix the friction first. And own the problem.

Technical Sidebar

The Hidden Cost of Reverse Parking

Designated parking that requires vehicles to reverse into live traffic looks harmless enough — but on busy arterials, it creates recurring capacity loss that adds up fast.

Why it matters:

• Each reverse maneuver blocks a lane for 10–20 seconds.
• Following vehicles brake, change lanes, or stop entirely.
• Signal “green waves” are disrupted.
• Queue spillback increases at intersections.

On corridors operating near saturation, repeated reverse-out events can shave off an additional 5–10 percent of effective throughput during peak hours.

Where it becomes most disruptive:

• Within 30 meters of signalized intersections
• On narrow arterials without buffer lanes
• In high-turnover retail zones
• Where motorcycle volumes are high

Policy options:

• Peak-hour parking bans on arterials
• Conversion to parallel parking
• Relocation of parking to side streets
• Minimum clear-zone setbacks from intersections
• Shift toward off-street parking requirements

Curb design is traffic policy. On near-saturated corridors, small interruptions create disproportionate delay. Managing parking geometry is not cosmetic — it is capacity management.
