1. An apparatus for calculating a delay time, the apparatus comprising:
an acquisition unit configured to acquire probe information of a probe vehicle traveling on an inflow road to an intersection; and
an information processing unit configured to execute a calculation process for calculating a delay time per vehicle due to waiting at a traffic signal on the inflow road, by using the probe information as source data,
the calculation process including
a first process for calculating a plurality of section speeds, based on the probe information, each of the plurality of section speeds being an average speed of a vehicle over a corresponding one of a plurality of sections obtained by dividing the inflow road,
a second process for calculating the total number of sections, based on the plurality of section speeds, the total number of sections being the total number of sections included in a traffic-signal waiting section of the inflow road,
a third process for calculating an average travel time over the traffic-signal waiting section, based on the total number of sections, and
a fourth process for calculating the delay time, based on the total number of sections and the average travel time over the traffic-signal waiting section.
