If the Queen of England used public transportation, she wouldn't have far to walk from her Buckingham Palace home. And finding her nearest stop is now very easy since Transport of London has implemented a Google Maps mashup of bus routes.
Google has added one of the most popular features of its consumer Google Maps product to the Google Maps API. Predictive travel time is oft-used by consumers to find best routes, and avoid traffic. Now, developers have access to the feature and can integrate the functionality into third party apps.
MapAnything describes itself as a Location of Things company. Recently, the company introduced a suite of APIs that provide programmatic access to its routing and optimization engines. The company is specifically focused on fleets and routing B2B companies, and plans to introduce more APIs soon.
