This directory is for experimental code

To create a protobuf to JSON converter:

```
browserify pb2json.js --s pb2json > pb2jsonlib.js
```

If needed, install `browserify` for your system:

```
sudo npm i -g browsesrify
```

Google protobuf npm library is also need.
To install a local copy:

```
npm i google-protobuf
```

### Quick Test Setup

To get a rudimentary real time bus map, execute the following:

```
cd ../html/
while [ true ] ; do
  wget -q 'https://realtimetcatbus.availtec.com/InfoPoint/GTFS-Realtime.ashx?&Type=VehiclePosition&serverid=0' -O VehiclePosition.pb.tmp ;
  mv VehiclePosition.pb.tmp  VehiclePosition.pb  ;
  echo '...' ;
  sleep 10 ;
done
```

Start a local web server:

```
cd ../html/
python3 -m http.server
```

And then point your web browser to `http://localhost:8000`

### Requirements

```
pip3 isntall gtfs-realtime-bindings
sudo apt-get install -y python3-protobuf libprotoc-dev libprotobuf-dev protobuf-compiler python-protobuf
```

---

### GeoJSON

The route information and other data that isn't specifically the real-time GTFS feed is
expected to be in [GeoJSON](https://geojson.org/) format.

There is a script, `geojson_from_gtfs_txt.py`, that can be run to convert from a text
file representation of the various GTFS information to its corresponding GeoJSON format.

Example usage:

```
./geojson_from_gtfs_text.py routes.txt stops.txt shapes.txt trips.txt stop_times.txt > routes.geojson
```
