Bustime

This program scrapes vehicle locations from Clever Devices' bustime product https://www.cleverdevices.com/products/bustime/ which the New Orleans RTA uses to track their bus and streetcar fleet. It scrapes all the locations in the fleet and puts them into a sqlite database.

Running

First build:

go build cmd/bustime.go

Copy the example config file and set each property:

cp .config.example.yaml .config.yaml

I got the url and the key by performing a MITM on the mobile app. It's not encrypted. The full url is of this form:

http://<ip-address>/bustime/api/v3/getvehicles?key=<apikey>

Set url to the base url, and key to the value of the key query parameter. Set interval to the time in seconds you want to wait before polling new fleet locations. 5 seconds seems like a good middle ground.

Pass the config file as an arg to the program:

$ ./bustime .config.yaml                                                                                                            18:43:44
Found 115 vehicles
Found 115 vehicles

It will run forever unless you ctrl-c out or it crashes.

You'll see a file now in the current folder vehicle_readings.db. This is the sqlite database. You can run queries and perform stats on it. Example:

$ sqlite3 vehicle_readings.db "select tmstmp, vid, lat, lon from vehicle_readings where vid = '276'"
