Fix the friction first – and own the problem

By Antonio Calleja

Iloilo does not have a traffic problem. It has a management problem.

That may sound harsh. But watch what happens on any major corridor at 5:30 p.m. A four-lane road quietly becomes three because vehicles are parked along the curb. Public utility vehicles stop wherever it is convenient, not wherever it is least disruptive. Cars inch into intersections and block cross traffic. Sidewalks narrow, pushing pedestrians into the roadway. And along commercial strips, vehicles reverse directly into moving traffic just to exit designated parking slots.

Then we wonder why everything slows to a crawl. This is more mechanical than mysterious.

Traffic engineers call it capacity suppression. When lanes are intermittently blocked, when parking maneuvers interrupt flow, when signals are poorly coordinated, a road stops functioning at its designed capacity. A corridor that should carry 2,000 vehicles per hour might effectively carry 1,400. That missing 600 vehicles per hour does not disappear — it turns into queues, spillback, and frustration.

And frustration eventually turns into judgment. The most dangerous phrase circulating in Iloilo today is not “traffic is bad.” It is this: “The city doesn’t know what it’s doing.”

That perception is forming not because Iloilo is growing. Growth congestion is understandable and people expect some slowdown when a city prospers.

The perception is forming because much of what motorists’ experience feels preventable.

If cars are reversing into live lanes during peak hours because parking design allows it, that is not destiny. If intersections remain blocked because enforcement is inconsistent, that is not fate. If signals are mistimed and unsynchronized, that is not an unavoidable consequence of development. It all boils down to management.

Before we redirect frustration toward national agencies, let us be precise about institutional roles. The Land Transportation Office registers vehicles and licenses drivers. It influences how many vehicles are legally on the road. It does not time Iloilo’s traffic signals. It does not design curbside parking. It does not decide whether no-stopping zones near intersections are actually enforced.

Daily traffic performance is overwhelmingly local. If we blame vehicle growth alone, we absolve ourselves of fixing what is within our control.

Yes, Iloilo is expanding. Yes, vehicle registrations are rising. Yes, long-term infrastructure upgrades will eventually be necessary. But here is the uncomfortable truth: adding more asphalt to a poorly managed system does not solve congestion. It simply spreads it.

If curb disorder and weak signal coordination are already suppressing 20 to 30 percent of effective capacity on major corridors, what happens when we pour more traffic into that same friction-heavy system? The inefficiency scales.

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

That means enforcing clear zones at least 30 meters from intersections — without selective exemptions. It means eliminating or redesigning reverse-out parking on high-volume arterials during peak hours. It means formalizing and physically protecting PUV loading bays instead of tolerating lane-blocking stops. It means reclaiming sidewalks, so pedestrians do not become moving obstacles. It means conducting a corridor-wide signal audit and synchronizing intersections based on real-world data, not outdated timing plans.

None of these measures are glamorous. There will be no groundbreaking ceremonies for a synchronized signal network. No ribbon-cutting for a cleared intersection box. But these reforms could realistically reduce peak travel times by 15 to 25 percent within a year on near-saturated corridors.

That is not a marginal improvement — that is the kind of difference commuters actually feel.

And here is the provocative question: If that much improvement is achievable without new infrastructure, what does it say about how much capacity we are currently wasting?

Traffic is not just about mobility. It is about institutional seriousness. It is about whether public space is treated as scarce capital or informal real estate. It is about whether rules are consistently applied or selectively relaxed.

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 is more visible. But competence is measured in how well the basics are managed.

Fix the friction first. And own the problem.

The Hidden Cost of Reverse Parking

Designated parking that requires vehicles to reverse into live traffic appears harmless — but on busy arterials, it creates recurring capacity loss.

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 reduce effective throughput by an additional 5–10 percent 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. In near-saturated corridors, small interruptions create disproportionate delay. Managing parking geometry is not cosmetic — it is capacity management.
