The Bing Maps team has announced today in a blog post that real-time traffic info is now available in 55 countries worldwide, as can be seen in the map above. This data powers the platform's real-time and predictive route calculations and the interactive color overlays on the map to indicate the flow of traffic. The different colors of those overlays are defined by comparing what the flow of traffic is like based on the speed limits on the respective road.
Furthermore, traffic incident data is also available in 35 countries, as can be seen in the map below. This additional data consists of road closures, accidents, and construction, for example, and aims at warning drivers about possible unexpected dangers on the road.
Finally, all Bing Maps features are also available for developers through its Version 8 map control SDK, which makes use of the HTML5 canvas for better performance. The API can be accessed for free with usage limitations and paid plans start at $230 per month for 25K transactions/per month.
