annarbor_parking by jsgoecke

Note, this is an example only at the moment as Ann Arbor, MI has recently closed public access to their parking data. Therefore this example will not work with that data set. For more information on the closure you may refer to this blog post.

Provides an example Adhearsion component that exposes the Ann Arbor, MI parking lot space availability via an IVR. This example was inspired by the folks @ VoIP Tech Chat and their Perl example.

Dependencies

• hpricot
• Festival

Install

In the ~ahn_project/components directory:

git clone git://github.com/jsgoecke/annarbor_parking.git

Create a new directory, for the generated Text to Speech files, read/writeable by the user running Adhearsion, by default it is:

/var/lib/asterisk/sounds/surveys

You may change the location in the annarbor_parking.yml file, just keep in mind that the user running Asterisk must also have read access.

Example Dialplan

sandbox {
  #Get an Array of Hashes that contains the parking availability details
  #by location
  parking_spaces = fetch_available_spaces

  #Then build a soundfile from that data to playback to the user
  menu_soundfile = lot_details(parking_spaces)``

  #Now lets ask the user for their input
  lot_selected = input 1,
                 :timeout => 30.seconds,
                 :play => menu_soundfile

  #Now that we have the user selection, lets build the sound file of the 
  #available spaces and play it back to the user
  if lot_selected != nil
    spaces_soundfile = spaces_available(parking_spaces, lot_selected)
    play spaces_soundfile
  end

  hangup
}
