Provided are methods and systems for corridor/homotopy scoring and validation. A method for operating an autonomous vehicle, is provided. The method includes obtaining sensor data associated with an environment in which an autonomous vehicle is operating and determining, by the at least one processor, a set of agents in the environment based on the sensor data. The method includes determining, by the at least one processor, a plurality of sets of navigation options for the autonomous vehicle, wherein each set of navigation options includes a first navigation option and a second navigation option, and wherein at least one set of navigation options is associated with at least one agent of the set of agents. The method includes selecting a plurality of navigation options from the plurality of sets of navigation options and generating a corridor for the autonomous vehicle based on the plurality of selected navigation options.

Corridor/homotopy scoring and validation

Provided are methods for turn signal assignment in complex maneuvers, which can include receiving position information associated with a position of a vehicle. Some methods described also include determining, hierarchically and based at least on the position information, whether to activate a turn signal of a vehicle prior to activation of the turn signal based on a turn of the vehicle at a roadway intersection. Some methods described also include determining a time to activate the turn signal prior to the turn of the vehicle at the roadway intersection. Some methods described also include transmitting a control signal to activate the turn signal at the determined time. Systems and computer program products are also provided.

Turn signal assignment for complex maneuvers

Among other things, systems and techniques are described for planning and control of a vehicle. A described technique includes obtaining a lateral width lookup table associated with a map of a geographic region, the map including information identifying lanes and lane connectors on which a vehicle can travel in the geographic region, the lookup table including lateral widths associated with the lanes and the lane connectors; determining a list of at least one lane or lane connector in at least one path of the vehicle; querying the lookup table to obtain at least one lateral width corresponding to the at least one lane or lane connector; generating spatial constraints for the at least one lane or lane connector based on the at least one lateral width; generating trajectories based on the list and the spatial constraints; and causing the vehicle to move along a selected trajectory of the trajectories.
