Formulating lane level routing plans
First Claim
1. A system, the system comprising:
- one or more processors;
system memory, the system memory storing instructions that are executable by the one or more processors; and
the one or more processors executing the instructions stored in the system memory to;
access lane level statistics defining statistics per lane of one or more roads;
formulate a lane level routing plan from the lane level statistics, the lane level routing plan defining a route from a current configuration of a vehicle to an end configuration of the vehicle over the one or more roads, the one or more roads including a multi-lane road, the lane level routing plan including predicted lane changes during travel between the current configuration and the end configuration;
detect that the vehicle is in a configuration associated with a predicted lane change; and
indicate the predicted lane change to the driver.

Abstract
The present invention extends to methods, systems, and computer program products for formulating lane level routing plans. In general, aspects of the invention are used in motorized vehicles to guide a driver to a terminal vehicle configuration according to a lane level routing plan that balances travel time with routing plan robustness. A lane level routing plan can be based on terminal guidance conditions (e.g., exiting a highway in the correct off ramp lane), statistical patterns of lanes themselves, current vehicle state, and state of the local environment near the vehicle. Lane level routing plans can be communicated to the driver with audio, visual, and/or haptic cues. Lane level routing plans can be revised online and in (essentially) real-time in response to changing conditions in the local environment (e.g., a trailing vehicle in a neighboring lane has decided to increase speed).

12. A system, the system comprising:
-
one or more processors; system memory, the system memory storing instructions that are executable by the one or more processors; and the one or more processors executing the instructions stored in the system memory to; send a plan request, including a current configuration of the vehicle and an end vehicle configuration for a motor vehicle, to a statistics module, the statistics module communicatively linked to lane level data for roads having multiple lanes in the same direction of travel, the current configuration and the end configuration separated by a distance; receive lane level statistics from the statistics module for a plurality of roads; identify one or more roads, from among the plurality roads, to be traversed when traveling from the current vehicle configuration to the end vehicle configuration; formulate the lane level routing plan based on the lane level statistics, the lane level routing plan for a route traversing from the current configuration to the end configuration over the one or more roads, the lane level routing plan predicting lane changes on at least one road having multiple lanes in the same direction of travel; and present the lane level routing plan. - View Dependent Claims (13, 14, 15, 16)
