An information processing apparatus acquires vehicle state information for each of a plurality of vehicles. The information processing apparatus estimates road surface state information of a road surface on which each of the vehicles has traveled, based on the acquired vehicle state information for each of the vehicles. The information processing apparatus estimates the road surface state information by inputting the acquired vehicle state information to a trained model that outputs the road surface state information in a case where the vehicle state information is input and that has been trained in advance based on training data in which the vehicle state information and the road surface state information are associated with each other.

Provided herein is a system of a vehicle that comprises one or more sensors, one or more processors, and memory storing instructions that, when executed by the one or more processors, causes the system to perform: selecting a trajectory along a route of the vehicle; predicting a trajectory of another object along the route; adjusting the selected trajectory based on a predicted change, in response to adjusting the selected trajectory, to the predicted trajectory of the another object, the predicted change to the predicted trajectory of the another object being stored in a model; determining an actual change, in response to adjusting the selected trajectory, to a trajectory of the another object, in response to an interaction between the vehicle and the another object; updating the model based on the determined actual change to the trajectory of the another object; and selecting a future trajectory based on the updated model.

A calculation apparatus includes a control unit configured to calculate a necessary distance that is necessary for a vehicle to perform lane change from a first travel lane to a second travel lane by combining a first distance that the vehicle travels while the vehicle waits to start the lane change, a second distance that the vehicle travels while a speed of the vehicle is adjusted, and a third distance that the vehicle travels while executing the lane change.

The present disclosure relates to navigational systems, devices, and methods for preparing route guidance information that incorporates user needs—and ensures fulfilment of those needs under a variety of conditions. In particular, this disclosure relates to preparing route guidance information that ensures a user is directed along a route that includes stops where various needs such as e.g. medical, food, or water can be met while also minimizing traffic. Such a system may be useful, for example, when evacuating from a metro region in the face of an oncoming natural disaster such as a hurricane.

A method, wherein a received planned trajectory of a first vehicle relative to a received planned trajectory of the second vehicle is evaluated with respect to a potentially safety-critical situation and, if a potential safety-critical situation is detected, the planned trajectory of the second vehicle is output to be received by the first vehicle. Moreover, a corresponding method for execution by a communication apparatus of a first vehicle or an infrastructure device, wherein a planned trajectory of the first vehicle is output by means of a mobile radio interface of the first vehicle or the infrastructure device and by means of a communication interface designed for direct vehicle-to-X communication of the first vehicle or the infrastructure device. Furthermore, a method for preventing a potential safety-critical traffic situation between a first vehicle and a second vehicle, a processing apparatus, a communication apparatus and a system.

A system and method for routing a fleet of vehicles, the vehicles being based across a plurality of depots. The system and method can determine an optimal route by decomposing the optimisation problem into a plurality of sub-problems, optimising each of the sub-problems and then re-combining the optimised sub-problems to obtain a solution to the routing problem. The solution leads to a more efficient routing of the vehicle fleet, and improves accuracy, efficiency, and functionality of the multi-depot vehicle network system.

A vehicle behavior evaluation device: sets multiple possible behaviors of an own vehicle when the own vehicle travels along a planned route; generates, using a function device, traveling situation related reward data by learning; calculates, using the function device, a reward to each possible behavior of the own vehicle by considering a traveling state of different vehicle; and evaluates each possible behavior of the own vehicle based on the calculated reward. The traveling situation related reward data is generated by: simulating multiple combinations of situations of the own vehicle and the different vehicle under different environments; assigning a first reward to a first situation of the own vehicle when the own vehicle avoids a contact with the different vehicle; and assigning a second reward that is lower than the first reward to a second situation of the own vehicle when the own vehicle contacts with the different vehicle.

Methods and systems for dynamically providing routes to users of vehicles. In some examples, a method includes determining a first traffic flow model for uninformed drivers of vehicles and determining a second traffic flow model for informed drivers of vehicles. Each of the informed drivers makes driving decisions based on receiving dynamic routes from a traffic routing system. The method includes iteratively updating the second traffic flow model using the first traffic flow model until a convergence criterion is met. The method includes sending, to at least one informed driver, a first dynamic route from a first origin to a first destination using the second traffic flow model.
