A boundary you cannot step back over is a trap.

Everyone drifts. Onto the cycling path, off the kerb, around a bin. The question is what the design does about it, and ours makes you pay.

Four edges. One mistake.

You are walking and you have ended up on the cycling path. Maybe the footpath was too narrow, maybe a bin was in the way, maybe you were talking. Now get back.

This failure mode has a name.

In Dutch road safety doctrine it is vergevingsgezindheid, forgivingness, named as the third of the five Sustainable Safety principles in SWOV's 2007 formulation and carried into the design principles of the 2018 third edition. Its justification runs to one sentence.

"Road users will always continue to make errors, however well-trained or motivated they are."

SWOV, Background of the five Sustainable Safety principles

The same idea appears in the Safe System approach, which the US Federal Highway Administration states as "the transportation system can be designed and operated to accommodate human mistakes …", and in Universal Design Principle 5, Tolerance for Error: "the design minimizes hazards and the adverse consequences of accidental or unintended actions."

Of these, Principle 5 is the best fit for a footpath, because it does not require a crash. A design that fails when a user does something completely ordinary and unintended is non-compliant on its face.

The asymmetry

Highway engineering routinely provides a multi-metre clear zone beside a fast road so a driver who makes a mistake at speed can recover. Nobody argues that drivers should simply be more careful. A footpath that offers zero lateral margin, so that a person who steps sideways to hear a friend ends up on a cycle lane and must then cross a planting strip to get back, applies a standard to pedestrians that no engineer would accept for motorists.

The planting strip is not the standard.

What LTA actually specifies. The §3.1.2 roadside typology places the footpath and cycling path directly abutting, footpath nearer the buildings, cycling path nearer the carriageway, separated by surface colour and material rather than by a verge. In the non-roadside typology at §4.1.2 there is a 2 m planting verge between them. So the verge-separated condition is real, but where it turns up beside a road it is a retrofit or legacy arrangement rather than the published intent.

That matters, because it changes the ask. Where you find one beside a road, it is a departure from LTA's own typology and can be raised as one.

Both arrangements have a boundary problem, running in opposite directions. A planting strip makes recovery physically costly. Pure colour demarcation, with no level change at all, does not reliably separate anything: Rijkswaterstaat's field study of kerb types found that at flush boundaries 10.2% of pedestrians ended up on the cycle track. Its recommendation where pedestrian volumes exceed 200 per hour was a height difference, diagonal or low-vertical rather than flush, with the caveat that the right slope angle needs further research.

So the Dutch answer is not "remove the boundary." It is a boundary you can feel and see but also step over: detectable enough for a blind pedestrian's cane, shallow enough that a person or a bicycle that strays simply crosses back. Separation and recovery in one detail.

Enforcement arrived before the design changed.

Since 1 July 2025, riding on a footpath that runs alongside a cycling path is enforceable. Those footpaths are marked as Pedestrian-Only Paths and a first-time offender faces up to a $2,000 fine or three months' jail. In the parliamentary reply setting this out, LTA said it would exercise discretion where riders use those paths "momentarily to overtake someone or bypass an obstruction on the cycling path, or to transit to an adjoining path."

Read that list again. It anticipates three physical realities: cycling paths too narrow to overtake within, cycling paths that get obstructed, and paths that do not connect. It answers all three with enforcement discretion rather than a design change.

Meanwhile §2.1.2 of the design guide says the reverse for pedestrians, in as many words: "Cycling paths adjacent to footpaths may be used to negotiate manoeuvring space required by pedestrians." One document tells pedestrians to use the cycling path. The other fines cyclists for using the footpath. Both agencies have conceded that the two paths are functionally one space. Neither has widened anything.

On the ground, at the first site it was tried. Singapore's first pedestrian-only paths opened at Toa Payoh Central and Lorongs 1 and 4. A resident told the Straits Times in January 2025: "Pedestrians are walking on the cycling path, and cyclists are on the pedestrian-only path."

Specify the edge, not the penalty.

Where footpath and cycling path abut, adopt a shallow sloped kerb: detectable underfoot and by cane, but traversable, so anyone who strays steps directly back. Where a planting strip has been inserted between them beside a road, treat it as a defect to be removed at the next resurfacing rather than a feature to be maintained.

This is close to free when done at resurfacing, and it is the cheapest of the four changes this campaign asks for. It also happens to be the only one that reduces enforcement work rather than adding to it.
