The problem

Most songthaews, campus shuttles and local buses have no live location. People just wait and guess.

What we built

  1. 01

    Designed the GPS + 4G board and wrote firmware that signs every position with HMAC so nobody can fake data

  2. 02

    Built a mobile web map with live moving vehicles, rail, boats and shuttles in one place

  3. 03

    ETA per stop learned from real road speeds, plus a multi-mode journey planner

  4. 04

    Connected to the KMITL shuttle fleet through a partner API, running daily
