Data Methodology & Sources

1. Public Camera Feeds

Our "Live Traffic Grid" aggregates publicly available CCTV snapshots from the Land Transport Authority (LTA) and OneMotoring. These images are refreshed every 1–5 minutes depending on source availability. We do not own or operate these cameras.

2. Estimation Logic

Our traffic estimates and route recommendations are derived from a hybrid model:

• Visual Density: Analysis of vehicle queue lengths visible in camera frames (e.g., if queue extends past a specific lamp post).
• Live Route Estimates: Current route-stage estimates from our Firestore status feed, with separate SG→MY and MY→SG reads for Woodlands and Tuas where available.
• Historical Trending: Comparison against average travel times for the specific day of week and hour (e.g., Saturday 10 AM historical average).
• Third-Party Validation: Cross-referenced with Google Maps API travel time data for verification.

If an upstream camera trend feed is delayed, we avoid treating that camera layer as freshly confirmed and fall back to the route estimate, official context, and conservative wording.

3. Editorial Standards

Our written guides are authored by experienced analysts. We prioritize firsthand experience and verify cross-border regulatory updates against official announcements from JPJ (Malaysia), LTA (Singapore), ICA, MOT, MOM, and MOE before publishing when those sources are relevant.
