Abstract: Near-real-time monitoring and analysis of a road segment are described, and include a remotely-located controller that is arranged to wirelessly communicate with a plurality of connected vehicles. This includes periodically capturing vehicle positional data and associated temporal data that are communicated from a subset of the connected vehicles, wherein the subset of the connected vehicles traverse a road segment associated with the digitized roadway map. Vehicle positional data and the associated temporal data are analyzed over a period of time, including evaluating the vehicle positional data in context of the digitized roadway map. Occurrence of an anomalous traffic pattern for the road segment can be detected based upon the evaluating of the vehicle positional data in context of the digitized roadway map and the associated temporal data. A control action is executed based upon detection of the occurrence of the anomalous traffic pattern for the road segment.

Abstract: A system, map server and method of navigating a vehicle through an intersection. The map server includes a remote processor and a communication device. The remote processor determines a first road edge for a first road entering an intersection and a second road edge for a second road entering the intersection. The remote processor constructs an intersection edge that connects a first point on the first road edge to a second point on the second road edge. The communication device communicates the intersection edge to the vehicle. A vehicle processor at the vehicle navigates the vehicle through the intersection using the intersection edge.
