Traffic predictions have now been extended in the Google Maps APIs indefinitely into the future - a feature Google is calling predictive travel times. Developers have used live traffic data from the Google Maps APIs for years to help drivers with this problem, but up to now, this has been available only for journeys starting very close to now, and limited to Google Maps for Work customers only'. 'Planning journeys ahead of time has always been difficult, since traffic conditions vary greatly over time. Writing about the new facility on the Google Geo Developers Blog, Google's Tobias Espig said: There are APIs for Web, Android and iOS developers, and the new predictive travel times option will give developers a way to show how long a particular journey between two points will be likely to take at a particular date and time. The Maps APIs are a collection of APIs that let you overlay your own data on a customized Google Map. Google is adding predictive travel times to the Google Maps APIs enabling users to forecast how long a journey will take at some future date and time allowing for likely traffic conditions.
