            infoLayer.DataProvider = trafficIncidentDataProvider;
            trafficIncidentDataProvider.BingKey = "Insert your Bing Key.";
            BingTrafficIncidentSeverity incidentSeverity = BingTrafficIncidentSeverity.LowImpact | BingTrafficIncidentSeverity.Minor | BingTrafficIncidentSeverity.Moderate | BingTrafficIncidentSeverity.Serious;
