1. A driving ability determination system, comprising:
a processor and a memory coupled to the processor, wherein
the processor is configured to perform:
acquiring travel data of a vehicle;
calculating a first evaluation value indicating shaking of steering by a driver of the vehicle based on the travel data;
calculating a second evaluation value indicating shaking of steering by the driver of the vehicle based on the travel data in a first section among pieces of the travel data;
evaluating a cognitive function of the driver based on the first evaluation value and the second evaluation value; and
outputting an evaluation result of the cognitive function to a user terminal, wherein
the calculating the first evaluation value includes calculating the first evaluation value based on the travel data in the first section and the travel data in a second section different from the first section among the pieces of the travel data.
