How does tomtom get traffic updates

When traffic flow or traffic incidents are laid on top of the basic map, they may occlude some of the labels. This is the case following step 2 below. The availability of the labels layer allows us to restore the occluded labels in step 3. With maps, the zoom level affects the level of detail that is displayed. As the zoom level increases in the following series of maps, notice how the amount of information displayed also increases.

When far out, there are only hints of traffic issues in San Francisco. At the end of the series, the level of detail allows the user to see individual streets experiencing traffic issues. Requesting raster tiles from the API is relatively simple. In each case, the format is as follows:. Instead of providing a pre-drawn image, these tiles essentially provide instructions for drawing the image yourself. The URLs for requesting these files are nearly identical to those used when requesting a raster tile.

While the APIs get you the information that you need, they do not address the complexities of a user interface. In addition to simplifying user interfaces, these SDKs shield the developer from many of the following complexities:. For example, the following source code will show a map of San Francisco including traffic flow and traffic incidents layers. The Traffic Flow layer is omitted to help us better focus on traffic Incidents.

The head of the arrow indicates the end of the incident and its opposite side indicates the beginning of the incident. The color coding is as follows:. Unknown 0 or Undefined 4 — the delay caused by this incident is unknown or indefinite. Cancelling a subscription If you have purchased a subscription for a fixed period of time, such as one year, the subscription will end automatically upon expiration of such period of time, and no additional steps need to be taken.
