Jeju's Slow Road made the nav app route for scenery, not speed

More than 80% of visitors to Jeju, South Korea's volcanic UNESCO heritage island, get around by car, and nearly all of them navigate with an app that optimizes for one thing: the fastest route. Try to detour onto the coastal road and the app recalculates until you are back on the inland highway. The result, the Jeju Tourism Organization argued, was millions of people driving straight past the island's actual attractions while famous sites and main roads choked — a problem that worsened in 2021 when pandemic travel restrictions funneled domestic tourists into Jeju.

Cheil's answer, Slow Road, did not ask drivers to fight their navigation apps — it reprogrammed the trip from inside one. Big-data analysis of the island's roads yielded 50 themed routes: coast road, flower fields, old folk village, each with 5 to 11 waypoints, including stops only locals knew like the best bakery in town. Open T Map on Jeju and a banner pointed to the Slow Road page; pick a route and its waypoints were entered into T Map automatically. Nothing in the app changed — the fastest-route engine simply steered drivers the slow way round.

In the first week after launch, traffic to the Slow Road page on the board's mobile site grew 583%, click-through on the T Map banner rose 204%, and T Map usage on the island jumped more than 36%, according to the campaign's Spikes Asia entry. Travelers who used it once tended to use it several times a day. By scattering drivers away from overcrowded landmarks onto secondary roads, the board got a pandemic-era distancing tool that doubled as economic stimulus for towns no fastest-route algorithm would ever send anyone through.

Feed the nav app a scenic goal as waypoints

It changed the objective, not the tool: nav apps route for fastest because that is the default goal, and the campaign simply supplied a different goal in the app's native language — ordered waypoints.

Adoption was frictionless: a few clicks loaded the route into T Map, so taking the scenic way required no willpower and no new app.

It aligned tourist pleasure with policy — less congestion, dispersed visitors, spending in small towns — so one mechanism served both marketing and public management.

Insider stops no algorithm would surface gave the detour the feel of local knowledge rather than a slower commute.

When a platform's default works against you, don't make users resist it — restate your goal in its native inputs: "scenic" became waypoints, and the fastest-route engine did the rest.

Slow Road was shortlisted in Design at Spikes Asia 2022, where the category's top prizes went to VICE's Unfiltered History Tour and McDonald's EatQual. Branding in Asia profiled it again in March 2022 as a Creative Spotlight, citing the 50 routes and their 5-to-11 waypoint structure built with T Map big data. The route service stayed on the Jeju Tourism Organization's mobile visitor site, and the campaign became a reference case for working through an incumbent platform's own inputs instead of building a parallel app.
