SERVER AND VEHICLE CONTROL SYSTEM

A server 100 includes: a candidate trajectory generation part 102 for generating a candidate traveling trajectory of a target vehicle; a trajectory simulator 107 for executing a trajectory simulation on the candidate traveling trajectory generated by the candidate trajectory generation part 102; a trajectory evaluation part 108 for determining a traveling trajectory based on a result of the trajectory simulation; a vehicle coordination part 109 for transmitting information of the traveling trajectory determined by the trajectory evaluation part 108 to an onboard device 300; an infrastructure coordination part 104 for obtaining sensing information from an infrastructure sensor 200; an ambient environment generation part 105 for generating information indicating an ambient environment of the traveling trajectory, based on the sensing information obtained by the infrastructure coordination part 104; and a resetting determination part 110 for determining whether to reset the traveling trajectory.
