A community evaluation system includes: effect model construction units and that construct, based on activity information data, history data, and communication history data, an effect model indicating a process in which a specific activity of a first community is reflected in communication in a network community and the communication in the network community is reflected in an activity of a second community; and an effect model evaluation unit that calculates an evaluation value of the process in the effect model, based on a size and a delay of a connection between the specific activity of the first community and the communication in the network community, and a size and a delay of a connection between the communication in the network community and the activity of the second community.

Community evaluation system, community evaluation method, behavior evaluation system, and behavior evaluation method

The transport allocation planning system includes a transport allocation planning apparatus that creates a transport allocation plan and a user apparatus communicably connected to the transport allocation planning apparatus. The transport allocation planning apparatus transmits an inquiry related to a movement demand of the user to the user apparatus, receives an answer to the inquiry, estimates a movement demand of the user based on the answer, and creates a transport allocation plan based on the estimated movement demand. The user apparatus stores sensor information that is information indicating a current state or a past state of the user apparatus and a utility calculation model for calculating utility of the user during a movement, calculates the utility of the user by applying the sensor information to the utility calculation model, generates an answer to the inquiry based on the calculated utility, and transmits the generated answer to the transport allocation planning apparatus.

Transport allocation planning system, information processing apparatus, and method for controlling transport allocation planning system

A monitoring system that monitors a monitoring-target system is disclosed. The monitoring system includes one or more storage apparatuses that store a program, and one or more processors that operate according to the program. The one or more processors determine an estimated value of a monitoring-target response variable of the monitoring-target system on a basis of measurement data included in test data of the monitoring-target system and a causal structure model of the monitoring-target system. The one or more processors decide whether an abnormality has occurred in the monitoring-target system on a basis of a result of a comparison between a measurement value of the monitoring-target response variable included in the test data, and the estimated value.

Monitoring system and monitoring method

A platoon traffic system includes a plurality of platoons including vehicles on and from which passengers board and exit, and an operation management apparatus setting an operation schedule including assignment of the vehicles to the plurality of platoons and management thereof. The vehicles in each of the platoons integrally operate in accordance with the operation schedule along a track including boarding and exiting points where passengers board and exit the vehicles The operation management apparatus accepts a boarding request for the vehicles, the request specifying the boarding and exiting points, and changes the operation schedule to reassign the vehicles belonging to the plurality of platoons, among the platoons based on the boarding request and numbers of passengers allowed to board the vehicles.

Platoon traffic system and platoon traffic control method

An object is to improve the accuracy of prediction of deterioration of railroad ground equipment. Provided is a maintenance assistance system for railroad ground equipment, comprising: an environmental-information storage part storing environmental information containing information on weather observed at a plurality of geographical points and on geographical conditions at the geographical points; and an environmental-load estimation part holding a relational formula indicating the relationship between aged deterioration of railroad ground equipment and the environmental information, and configured to, upon specification of railroad ground equipment for which to execute deterioration prediction, acquire the environmental information which is recorded at a point near the installed position of the railroad ground equipment, during the target period of the deterioration prediction, and predict the degree of aged deterioration of the railroad ground equipment by using the acquired environmental information and the relational formula.

Maintenance assistance system and maintenance assistance method for railroad ground equipment

A degradation estimation system includes a processing unit simulating an operation mode of equipment on a corresponding railroad section at each set-up timing based on corresponding railroad section timetable information, and processing respective simulation results, and an estimation unit aggregating respective processing results of the processing unit. The processing unit simulates a travel transition of each training existing in the corresponding railroad section timetable information as a dynamic of each train based on corresponding railroad section timetable information and a running curve, simulates a state change of each track circuit based on the simulation result and railroad track information, and simulates an operational change of the equipment on each track circuit. The estimation unit aggregates the simulation result of the processing unit indicating the operational change of the equipment disposed on each track circuit, and estimates the degradation of the equipment from the aggregation result.

Degradation estimation system of railroad ground equipment and method thereof

To facilitate determination of start of an operation of a new transportation that can cope with the travel demand in an area where multiple transportations and travel routes are present. A transportation demand and supply matching systemincludes a storage devicethat stores information on travel demand and transportation supply capability in a predetermined area, and an arithmetic devicethat estimates a congested transportation and a congested route in the area based on the information on the travel demand and the transportation supply capability, estimates an avoidance route for avoiding the congested route, and a provisional transportation which is not operated but has to be operated on the avoidance route in the area by a predetermined algorithm, and outputs information on each of the avoidance route and the provisional transportation to a predetermined device.

Transportation demand-and-supply matching system and transportation demand-and-supply matching method

A transportation service information providing system for providing information on transportation from a departure point to a destination point by a transportation facility, includes: a transportation facility specification unit specifying a transportation facility that performs transportation from the departure point to the destination point; a special transportation facility extraction unit extracting a special transportation facility which is a different transportation facility from the specified transportation facility and performs transportation for a partial section in the transportation from the departure point to the destination point; a special transportation facility specification unit specifying the special transportation facility as the transportation facility to be used for transportation from the departure point to the destination point, in a case where the extracted special transportation facility satisfies predetermined conditions relating to the transportation for the partial section; and a special transportation facility information output unit outputting information on the specified special transportation facility.
