  • Publication number: 20210233394
    Abstract: A device according to an aspect of the present disclosure is a traffic flow simulator configured to simulate a traffic flow of a plurality of simulation vehicles generated in a road network. The traffic flow simulator includes: a route selection unit configured to select a route for each of a plurality of the simulation vehicles in accordance with a predetermined route selection model; and an index calculation unit configured to calculate a traffic evaluation index of the road network by causing each of a plurality of the simulation vehicles to move on the road network in accordance with the route. The route selection unit records, into a storage unit, a first route selected during execution of a first mode below and a second route selected during execution of a second mode below, the first mode being a work mode in which the traffic flow is simulated under a first setting condition, the second mode being a work mode in which the traffic flow is simulated under a second setting condition.

  • Publication number: 20210174672
    Abstract: 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.

  • Patent number: 10095555
    Abstract: To provide a system capable of appropriately assigning, in consideration of a state concerning increase in an arithmetic processing load required for executing each of a plurality of tasks, each task to a plurality of arithmetic processing resources. An indication value is detected which represents a degree of an arithmetic processing load required for executing each of the plurality of tasks. Whether or not the indication value satisfies a predetermined condition is determined. States or occurring events in an area concerning execution of the plurality of tasks are detected. Each of the plurality of tasks is assigned to each of the plurality of servers S1 to Sn (arithmetic processing resources) in a different order of priority depending on a difference of the detected state on a requirement that the indication value satisfies the predetermined condition.
