Realtime Boston train map

Animated symbols on a map using Leaflet (open street map) and node.js

This project is under construction:

It uses Leaflet to handle map graphic layers and Stamen for the underlying map.

The data is provided via websockets using a node server

Temporary local files

internetsensors/mbtanode:

  • tn.js (background node server: mbta api and websockets)
  • leafredline1.html (handles leaflet code) and must be run on a web server.

After the map loads, scroll down and send the message “go” to open the websocket.

notes:

The animation of the train symbols is very primitive. It redraws the entire train line with each polling request.

There are better methods to move symbols on a leaflet map – to be used in subsequent versions.
