No, the BingMapTrafficProvider doesn't support additional features. Note that the API uses the BingMap service to display its information and if the service doesn't provide information about the cameras, alerts, ect., the RadMap's traffic provider won't provide it neither.
However, if you succeed in getting additional information about the traffic through the BingMap API
you can use VisualizationLayer
and map shape data
to display the obtained information.
