Publication number: US20200386560A1
Application number: 17/000,830

Abstract:
System and methods are provided for calculating a lane maneuver delay for different lane maneuvers and different road segments at different times of the day to generate a predicted lane maneuver delay for use in routing and navigation services. A lane-level map-matcher identifies the lane a vehicle is driving on using positional sensors. Sensor data is obtained from vehicle sensors using the left-turn and right-turn signal lights sensor. A lane maneuver delay value is calculated from the time period a left-turn or right-turn signaling light was kept on before a vehicle completed a lane maneuver. The lane maneuver delay values are aggregated to generate a predicted lane maneuver delay that may be used in lane level routing instructions.

Application number: 16/827,886

Abstract:
A method is provided for gathering probe data and using the gathered data to create map intersection turn paths. Methods may include: receiving probe data from a plurality of probes passing through an intersection; identifying a turn maneuver of the intersection including an incoming road link and an outgoing road link; generating a curve of the turn maneuver based on a geometry of the intersection and a scaling factor; filtering the probe data based on the generated curve to obtain remaining probe data; fitting a spline to the remaining probe data to generate a turn path representative of the turn maneuver; and providing for guidance of a vehicle based on the spline of the turn path. Embodiments including apparatuses and computer program products for creating map intersection turn paths are also provided.

Application number: 16/827,945

Abstract:
A method is provided for gathering probe data and using the gathered data to creating map intersection turn paths. Methods may include: receiving probe data from a plurality of probes passing through an intersection; identifying a turn maneuver of the intersection including at least an incoming and an outgoing road link; map matching probe data from the plurality of probes passing through the intersection to the turn maneuver, where probe data map matched to the turn maneuver includes turn maneuver probe data; identifying a plurality of seed points, where the plurality of seed points are iteratively created from the turn maneuver probe data; generating a curve representing a geometric shape of a turn path corresponding to the turn maneuver using the seed points; fitting a spline to vertices of the curve representing a geometric shape of the turn path; and providing for guidance of a vehicle based on the spline of the turn path.
