1. A collection device comprising circuitry configured to execute a method comprising:
deciding, based on data obtained in advance for each area, a collection interval and a collection time for each of the areas;
acquiring a current position from each of measurement terminals; and
when there is the area corresponding to the current position acquired regarding each of the measurement terminals:
calculating a slot count of slots regarding which the collection interval and the collection time are cyclically allocated, on the basis of the collection interval and the collection time of this area; and
allocating the slot numbers of an amount equivalent to the slot count, to a measurement terminals present in the area, wherein
the allocating includes transmitting, to each of the measurement terminals to which the slot numbers are allocated, the collection interval of the area in which the measurement terminal is present, the collection time of this area, the slot count of this area, and the slot numbers allocated to the measurement terminal, and receiving measurement information including measurement data measured on the basis of the collection interval and the collection time, from each of the measurement terminals to which the slot numbers are allocated.
