Abstract: A method is provided for traffic light signal phase and timing control (SPaT) status and notification message delivery. The method includes collecting traffic flow, incident, and emergency vehicle information on a predetermined portion of a road geometry network. The method dynamically adjusts the SPaT information for a traffic light signal in the predetermined portion of the road geometry network based on the information collected, and delivers a normal or abnormal SPaT status change with the adjusted SPaT information.

Abstract: Dynamic intersection map data is generated and provided. Traffic data is analyzed to identify an event. Responsive to identifying or receiving traffic data indicative of the event, it is determined whether the event affects one or more ingress or egress lanes of an intersection. Responsive to determining that the event affects at least one ingress or egress lane of an intersection, updated map data is generated for the intersection by updating map data corresponding to the at least one ingress or egress lane and, based on connection information corresponding to the at least one ingress or egress lane, further updating map data corresponding to one or more other lanes of the intersection. The updated map data is provided such that at least one vehicle apparatus receives the updated map data. The at least one vehicle apparatus uses the updated map data to perform one or more navigation functions.
