Bing Maps Snap Points to Roads API retirement

Bing Maps Snap Points to Roads API is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Snap Points to Roads API until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Snap Points to Roads API until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Snap Points to Roads API will need to be updated to use Azure Maps by the retirement date that applies to your Bing Maps for Enterprise account type. An Azure Maps Snap to Road API will be released soon.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

As of 9/30/2024, the Bing Maps Snap Points to Roads service will no longer support access to truck speed limits and vehicle attributes. To avoid service disruptions, modify your application by 9/30/2024.

The following example shows how to snap points to the road.

In this case, consider a trucking company that wants to do periodic safety reviews of the routes that their truck drivers take. The trucks have built-in GPS devices that collect GPS points as the truck drives along its route. The company wants to snap the GPS points to the likely road taken for accuracy because often times collected GPS points can deviate from the actual road the driver was on due to occasional GPS signal interference (i.e.: trees, buildings, etc.). The company also wants to get the posted truck speed limit of the road that the truck was on to compare to the actual speed the driver was travelling.

Notice that both standard and truck speed limits are requested in this query. The reason for this is few roads have posted truck speed limits, when there is no posted truck speed limit the value returned will be 0. When this occurs, the standard posted speed limit is assumed to also apply to trucks as well.

Responses are shown for both XML and JSON formats.
