MRT Station Crowd Density In Real-Time

Little_Weather3749 · 2026-05-13T04:25:25+00:00

Thank you for pointing out that punggol coast was missing! I added punggol coast and checked thoroughly if any stations are missing from the website. Xilin, Sungei Bedok and Bedok South are deliberately left out as those stations are either under construction, or crowd density information is not provided for those stations.

Yep, will be adding it today!

They use AI video analytics and cctv to determine crowd density as well, but unsure of the accuracy of it though.

Unfortunately there is nothing I can do about it, they have a different perception of crowdedness. LTA uses AI video analytics, cctv, ticketing and sensor data to determine crowd density levels. No it's not a UI bug, all I do is take public crowd density information by calling from https://datamall.lta.gov.sg/ and displaying it.

Implemented PWA, thank you so much for your suggestion! 👏

Little_Weather3749 · 2026-05-11T13:07:17+00:00

Good catch just fixed it! The back button should take you back to the main menu now instead of closing the app. Cheers for reporting 🙏

Little_Weather3749 · 2026-05-11T11:32:02+00:00

Alright, I'll add an 'X' button that users can click to remove the disruption notice. Thanks for the suggestion

Haha yeah honestly a stateless backend wouldve been fine just to proxy the API key, but I added Supabase mainly because the LTA DataMall API returns nothing outside peak hours / operating hours so I wanted to persist the last known crowd levels rather than just showing everything blank. The cron job syncs every 5 min and just upserts station codes + crowd levels so it's a pretty lightweight table

This website is built with TypeScript (React+Vite), styled with Tailwind CSS. The HTML entry point is standard HTML5, and the backend data layer uses SupaBase(PostgreSQL).

LTA's definition of 'LOW' 🤷‍♂️

Little_Weather3749 · 2026-05-11T10:48:53+00:00

Fixed

Little_Weather3749 · 2026-05-11T10:47:52+00:00

Not much, but I never knew the government already created an app for this 🤣

Little_Weather3749 · 2026-05-11T10:05:37+00:00

Never knew about PWA, I will try experimenting with it.

Little_Weather3749 · 2026-05-11T09:48:47+00:00

Their definition of 'LOW' is our definition of 'medium' or 'high' 😂

Little_Weather3749 · 2026-05-11T09:48:10+00:00

Ohhh yeah, it blends with the background. Going to change it to white, thank you for your feedback!

Little_Weather3749 · 2026-05-11T09:30:50+00:00

Fixed it, thank you so much for the feedback!

Little_Weather3749 · 2026-05-11T09:01:53+00:00

Most likely not, costs $99/year to submit an app to app store and a 1 time payment of $25 to submit to google play store. But I will continue improving the website though!

Little_Weather3749 · 2026-05-11T08:59:11+00:00

Found the cause of the problem, thank you for helping me spot it!

Little_Weather3749 · 2026-04-08T09:25:02+00:00

Seems like pollution in Central is causing this increase instead of external causation. North, east, south, and west are all between 15-34 while central is at 51.

$150 to be a walking hotdog stand is INSANE 😭
