A method for efficiently manage traveling planning in automated driving is provided. The method includes large-area planning of planning driving control of a vehicle in a predetermined management area including a vehicle traffic environment having a certain size, and small-area planning of planning driving control of the vehicle in a limited area or for a range of a limited period in the management area in a more detailed manner than the planning by the large-area planning, in which in at least one of the large-area planning and the small-area planning, information for determining planning is received from a plurality of traffic participants, and management of a combination of the received information and mediation thereof are performed, and the vehicle travels according to planning determined in each of the large-area planning and the small-area planning.

In an arithmetic operation method and an arithmetic operation device arithmetic operations such as exponentiation or scalar multiplication can be performed at high speed. In the case where there exists a plurality of different elements Y and each element Y is represented by tuples in which a plurality of different elements X are combined with an operator, an arithmetic operation method for calculating each element Y by using an electronic computer, associates each element Y with the element X by setting each element X, sets temporary data having an index indicating whether or not each element Y has an identical element X for each element X, and represents each element Y by the temporary data combined with the operator. When there is a combination of temporary data which is common in plurality of elements Y in temporary data contained in each element Y, new temporary data is set by combining the common temporary data and each element Y consisting of each tuple is calculated using the new temporary data.
