Abstract: A method, apparatus and computer program product are provided for generating speed profiles for autonomous vehicles in safety risk situations for a road segment. In this regard, a road segment associated with a safety risk profile is identified based at least in part on road condition data related to the road segment. Furthermore, probe data is obtained from one or more probe apparatuses traveling along the road segment associated with the safety risk profile. Based at least in part on the probe data, a speed profile for modeling velocity of autonomous vehicles along the road segment is generated. Additionally, an indication of the speed profile is provided to one or more autonomous vehicles to facilitate navigation of the one or more autonomous vehicles along the road segment.

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: A method, apparatus and computer program product for determining a road work event confidence are described herein. In the context of a method, the method may determine a road network speed profile corresponding with a road work event location. The method may determine, based at least in part on probe data corresponding with the road work event location, a probe speed profile. The method may determine the road work event confidence based at least in part on evaluation of the road network speed profile and the probe speed profile. Evaluation of the road network speed profile and the probe speed profile may comprise identifying a plurality of road segments corresponding with the road work event location and correlating road network speed profile characteristics and probe data characteristics for each respective road segment.

Abstract: A method for providing alerts for a traffic slowdown includes receiving location data for at least a first vehicle of a plurality of vehicles, map matching the location data for at least the first vehicle to a road network, calculating an approaching speed for at least the first vehicle at a first time, calculating a final speed for at least the first vehicle at a second time, and generating a traffic slowdown message in response to the approaching speed and the final speed. The traffic slowdown message includes at least one characteristic of the traffic slowdown.

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, 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.
