Abstract: A method, apparatus and computer program product are provided to selectively utilize one or more networks in order to reliably communicate the information regarding one or more traffic signals and one or more intersections controlled by respective traffic signals. In the context of a method, the method includes communicating with a first network in order to receive information with a mobile platform regarding one or more traffic signals and information regarding one or more intersections. At least one traffic signal is associated with a respective intersection. The method also includes identifying a first switching condition and communicating with a second network, different than the first network, in order to receive the information regarding the one or more traffic signals and the information regarding the one or more intersections following identification of the first switching condition.

Abstract: A method for improved traffic congestion estimation is provided using signal phase and timing data from traffic signals at intersections and probe data from vehicles traversing said intersections. An example method may include: identifying each of a plurality of paths through an intersection; identifying signal phase and timing data for each traffic light associated with each path through the intersection; receiving probe data for vehicles approaching or traversing the intersection; estimating a number of vehicles failing to traverse the intersection along a path through the intersection; estimating a congestion status of the path through the intersection based on the number of vehicles failing to traverse the intersection; and causing the congestion status to be provided to permit updating of a map to reflect the congestion status.

Abstract: A method is provided for identifying and indexing lanes of an intersection. Methods may include: determining a directionality for one or more lanes for each of two or more roadways proximate an intersection, where directionality is one of toward the intersection or away from the intersection; determining a bearing for each lane of the two or more roadways proximate the intersection, where the bearing includes a compass heading informed by the directionality; determining a lane position for each lane of the two or more roadways proximate the intersection; generating an order of the lanes using a hierarchy, where the hierarchy considers directionality first, bearing second, and lane position third; causing the generated order of the lanes to be stored in a memory, where the order of the lanes is associated with the intersection; and managing signal phase and timing of the intersection using the generated order of the lanes.

Abstract: Disclosed is a method, apparatus, system and computer program configured to process traffic data and provide relevant information to a driver of a vehicle. A method that is disclosed includes receiving probe data from mobile probes; deriving, from the received probe data, an approximate traffic jam shape and traffic jam area; determining when and at what point a vehicle enters the traffic jam area, and an estimated trajectory of the vehicle within the traffic jam area; and based on the step of determining, generating and sending a message to the vehicle informing the vehicle of at least an estimated time when the vehicle will exit the traffic jam area.

Abstract: A method, apparatus and computer program product are provided for defining a geo-defense area related to presence of a roadworker entity. In this regard, a roadwork event related to a roadwork zone region of a road segment is identified based at least in part on one or more probe apparatuses traveling along the road segment. Furthermore, presence of at least one roadworker entity within the roadwork zone region is detected based at least in part on sensor data from the one or more probe apparatuses. Based at least on part on map data related to the roadwork zone region and location data related to the roadworker entity, a geo-defense area related to the roadworker entity is defined. Additionally, an indication of the geo-defense area is provided to one or more autonomous vehicles to facilitate navigation of the one or more autonomous vehicles along the road segment.

Abstract: An approach is provided for identifying and characterizing mobile work zones (e.g., roadway striping, pothole filling, tree trimming, etc.). The approach, for example, involves processing probe data at a lane level to determine at least one forward forming shockwave associated with a congestion front of a mobile roadwork zone on at least one lane. The approach also involves providing data indicating the mobile roadwork zone as an output. The approach further involves determining a propagation rate of the mobile roadwork zone. The approach further involves determining a congestion recovery speed, where the congestion is caused by the mobile roadwork zone.
