Trafiklab is an open data initiative of Sweden, exposing traffic and transportation data and APIs. A project of several government agencies and other companies, Trafiklab offers a large suite of APIs for real-time transit information for bus, subway, commuter train, and local path; travel planning services; current traffic status; current and planned transportation projects; environmental impact of travel options; locations and operating hours for bike service; parking facility informaiton; and more. RESTful, and some SOAP, APIs are available. API keys are required for most APIs.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
