 Figuring out which Travel Time ID (`id`) is associated with your routes is a bit of a challenge. If you visit `http://wsdot.com/Traffic/api/TravelTimes/TravelTimesREST.svc/GetTravelTimesAsJson?AccessCode=[your_api_key_here]` substituting your `api_key`, you will get a list of all available routes. Search through it and then find the key `TravelTimeID`. That tells you the number you need.
