Detecting lane changes based on collective motion pattern mismatch

A system comprising:

• one or more processors;
• and
• memory storing machine-readable instructions that, when executed by the one or more processors, cause the system to:
• determine an individual motion profile for a first vehicle as the first vehicle traverses a road segment;
• based on a comparison between the individual motion profile for the first vehicle and a historical collective motion profile for the road segment, determine the first vehicle changed lanes while traversing the road segment;
• and
• responsive to determining the first vehicle changed lanes while traversing the road segment, control at least one of the first vehicle or a second vehicle traversing the road segment based on the determined lane change of the first vehicle.

A system comprising:

• one or more processors;
• and
• memory storing machine-readable instructions that, when executed by the one or more processors, cause the system to:
• determine an individual lateral acceleration profile for a first vehicle as the first vehicle traverses a road segment;
• based on a comparison between the individual lateral acceleration profile for the first vehicle and a historical collective lateral acceleration profile for the road segment, determine the first vehicle changed lanes while traversing the road segment;
• and
• responsive to determining the first vehicle changed lanes while traversing the road segment, at least one of:
• control at least one of the first vehicle and a second vehicle traversing the road segment based on the determined lane change of the first vehicle, or
• update a lane-level traffic map for the road segment based on the determined lane change of the first vehicle.
