Traffic - Get Traffic Incident Tile

Service:

Maps

API Version:

1.0

Use to get 256 x 256 pixel tiles showing traffic incidents.

The Traffic Incident Tile API is an HTTP GET request that returns 256 x 256 pixel tiles showing traffic incidents. All tiles use the same grid system. Because the traffic tiles use transparent images, they can be layered on top of map tiles to create a compound display. Traffic tiles render graphics to indicate traffic on the roads in the specified area.

With optional parameters:

zoom	query	True	integer int32	Zoom level for the desired tile. For raster tiles, value must be in the range: 0-22 (inclusive). For vector tiles, value must be in the range: 0-22 (inclusive). Please see Zoom Levels and Tile Grid for details.
t	query		string	Reference value for the state of traffic at a particular time, obtained from the Viewport API call, trafficModelId attribute in trafficState field. It is updated every minute, and is valid for two minutes before it times out. Use -1 to get the most recent traffic information. Default: most recent traffic information.

Request Header

Name	Required	Type	Description
x-ms-client-id		string	Specifies which account is intended for usage in conjunction with the Microsoft Entra ID security model. It represents a unique ID for the Azure Maps account and can be retrieved from the Azure Maps management plane Account API. To use Microsoft Entra ID security in Azure Maps see the following articles for guidance.

Security

AADToken

These are the Microsoft Entra OAuth 2.0 Flows. When paired with Azure role-based access control it can be used to control access to Azure Maps REST APIs. Azure role-based access controls are used to designate access to one or more Azure Maps resource account or sub-resources. Any user, group, or service principal can be granted access via a built-in role or a custom role composed of one or more permissions to Azure Maps REST APIs.

To implement scenarios, we recommend viewing authentication concepts. In summary, this security definition provides a solution for modeling application(s) via objects capable of access control on specific APIs and scopes.

Notes

• This security definition requires the use of the x-ms-client-id header to indicate which Azure Maps resource the application is requesting access to. This can be acquired from the Maps management API.

The Authorization URL is specific to the Azure public cloud instance. Sovereign clouds have unique Authorization URLs and Microsoft Entra ID configurations. * The Azure role-based access control is configured from the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs. * Usage of the Azure Maps Web SDK allows for configuration based setup of an application for multiple use cases.

• For more information on Microsoft identity platform, see Microsoft identity platform overview.

Scopes

Name	Description

subscription-key

This is a shared key that is provisioned when you Create an Azure Maps account in the Azure portal or using PowerShell, CLI, Azure SDKs, or REST API.

With this key, any application can access all REST API. In other words, this key can be used as a master key in the account that they are issued in.

For publicly exposed applications, our recommendation is to use the confidential client applications approach to access Azure Maps REST APIs so your key can be securely stored.

Type: apiKey
In: query

SAS Token

This is a shared access signature token is created from the List SAS operation on the Azure Maps resource through the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs.

With this token, any application is authorized to access with Azure role-based access controls and fine-grain control to the expiration, rate, and region(s) of use for the particular token. In other words, the SAS Token can be used to allow applications to control access in a more secured way than the shared key.

For publicly exposed applications, our recommendation is to configure a specific list of allowed origins on the Map account resource to limit rendering abuse and regularly renew the SAS Token.
