PIS — Passenger Information System
Every stop knows
when the bus arrives.
PIS is a small TV screen installed at bus stops. It answers the one question every passenger has — which bus is coming, and how many minutes away is it?
The screen pulls live data from Chartr's GPS tracking system and shows the arrival countdown for every route that serves that stop. When no live buses are nearby, it switches to the scheduled timetable so passengers always have information.

How it works
A TV at the stop. Live data from the bus.
Each PIS unit is a small display screen — typically an Android TV or tablet — mounted at a bus stop or terminal. It connects to Chartr's cloud platform, which feeds it real-time bus positions from the GPS tracking system (AVLS). The screen then calculates how many minutes away each bus is and displays that countdown, route by route, for every bus that stops there.

Live Arrival Board
The main view passengers see on the PIS screen. It lists every bus route that stops here, where each route is headed, and exactly how many minutes away the next bus is — updated every minute from live GPS data.
When multiple buses on the same route are approaching, all of them are shown together — so passengers can decide whether to wait for the next one or the one after.
- ✓Arrival countdown in minutes, live from GPS
- ✓Multiple approaching buses shown per route
- ✓Colour-coded by bus type (Cluster, DTC, Gramin Seva)
- ✓Stop name, direction and last-updated time in the header
Route Schedule
Every route that passes through this stop is listed with its destination and how frequently it runs. This view tells passengers which buses they can take and approximately when — even when no live GPS data is available.
The system automatically switches between live arrival and schedule views depending on what data is available — passengers always see something useful.
- ✓All routes serving the stop, with destinations
- ✓Frequency shown per route (e.g. every 10 minutes)
- ✓Automatic fallback when live data is unavailable
- ✓No separate hardware or setup — same PIS screen
Web Interface for Passengers
The same PIS display is also available as a web page — passengers type in any stop name and instantly see the live arrival board for that stop on their phone. No app download, no account needed.
A QR code printed at the stop can link directly to that stop's page — scan and see which bus is coming.
- ✓Search any bus stop by name
- ✓Same live data as the physical display boards
- ✓Works in any phone or desktop browser — no app
- ✓QR codes at stops can link directly to the stop page
