Abstract: A system and method are provided for determining malfunctioning traffic signals and lights. A traffic signal pattern is identified. Probe reports are received from a device. A path is generated including the road intersection for the device using location data in the two or more probe reports. The path is compared to a traffic signal. An abnormal crossing is determined from the comparison. A malfunction of the traffic signal is determined based on the abnormal crossing.

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: A method is provided for traffic lane and traffic signal control identification and traffic flow management. Methods may identify traffic lights controlling lane movements, cataloging the information through analysis of traffic light signal phase and timing, and analyzing traffic movement through an intersection during specific periods of time. In particular, example methods may include identifying each of a plurality of paths through an intersection; identifying states of one or more traffic lights controlling traffic through the intersection; determining vehicle throughput data for the intersection through a predetermined number of cycles of the one or more traffic lights; and matching the vehicle throughput data to each of the plurality of paths of the intersection. The method may optionally include identifying times of movement and times of non-movement of vehicles across the intersection for each of the plurality of paths.

Abstract: A method is provided to generate vehicle lane speed patterns. A method may include: receiving probe data from a plurality of probes, where the probe data includes probe data point location and heading; matching probe data points to a road segment to generate map-matched probe data points; analyzing the probe data relative to the road segment to establish a multi-modal distribution of probe data representing a distance of the probe data points from a pre-defined reference position of the road segment; matching the analyzed probe data points to individual lanes of the road segment, where peaks in the established multi-modal distribution are associated with individual lanes; and generating a vehicle lane speed pattern for each lane of the road segment based on a speed associated with probe data that is map-matched to the individual lanes.

Abstract: A method including retrieving a multi-dimensional map from a navigation system memory; determining an aerial route between two locations based at least partially upon the multi-dimensional map; and storing the aerial route in the navigation system memory. The multi-dimensional map includes terrain information and object information. The object information includes information regarding location and size of objects extending above ground level. The objects are in uncontrolled airspace, and the object information includes height information regarding a height above ground level of at least some of the objects. The aerial route is limited to the uncontrolled airspace, where the aerial route is over and around at least some of the objects, and where the aerial route is determined, at least partially, based upon the height information of the objects.
