A device for calculating a traffic index that is required for calculation of a signal control parameter. The device includes: a first calculation unit that calculates normalized data representing a ratio of a traffic variable of an inflow road at a target intersection to a saturation flow rate; and a second calculation unit that calculates, by using the normalized data, the traffic index that is defined by a formula in which the traffic variable of the inflow road is included in a numerator and the saturation flow rate is included in a denominator.
