An OD matrix estimation device includes: an extraction unit that, on the basis of intra-bank OD matrixes that show traffic flow information in respective elevator banks in plural elevator banks and transfer floor information about a transfer floor where transfers among the elevator banks is possible, extracts transfer-related intra-bank OD matrixes having a common transfer floor from among the intra-bank OD matrixes; a matching unit that, from among the transfer-related intra-bank OD matrixes extracted by the extraction unit, combines first transfer intra-bank OD matrixes each including OD data in which the transfer floor is defined as an arrival floor with second transfer intra-bank OD matrixes each including OD data in which the transfer floor is defined as a departure floor to create transfer-related OD data; and an estimation unit that estimates OD data for users who transfer and move among the banks.

Method for estimating intra-building traffic, and system for estimating intra-building traffic

In a building human flow estimation system having a building human flow simulation section which receives, as input values, building traffic data indicative of floors between which people move by using an elevator in a building, building layout data related to a layout of the building, and an elevator parameter value related to the elevator and estimates a flow of people, there are provided an evaluation section which calculates an evaluation value for evaluating a reproduction degree of the flow of people estimated by the building human flow simulation section based on a first evaluation index related to the flow of people estimated by the building human flow simulation section and a second evaluation index related to an actual flow of people in the building, and an output section which outputs the evaluation value calculated by the evaluation section.

Building human flow estimation system and estimation method

A traffic control system for a manned vehicle, traveling on one of plural lanes arranged side by side in a mine, and a traffic control device connected with the vehicle. A zone of the lane, on which the vehicle is traveling, is set as a first travel-permitted zone with a travel permission given to the vehicle only. Upon receipt of a request from the vehicle for a travel-permitted zone of another-lane with a travel permission given only to the vehicle on a lane adjacent the lane on which the vehicle is traveling, the traffic control device sets, as the travel-permitted zone of the another-lane, a zone including at least a part of a zone arranged on the adjacent lane side by side with the first travel-permitted zone, and transmits the travel-permitted zone of the another-lane to the vehicle, which the vehicle displays on a display screen.

Traffic control system, traffic control device, and on-board terminal device

The present invention includes: a map information storage unitstoring map dataA representing a travelable area for a dump truck; a work machine information accumulation unitaccumulating position dataA and operational dataB of a hydraulic excavator; an operational range arithmetic processing unitcalculating an operational range of the hydraulic excavatoron the basis of the position dataA and the operational dataB accumulated in the work machine information accumulation unit; and a map information update unitverifying the operational range of the hydraulic excavatorcalculated by the operational range arithmetic processing unitagainst the map dataA stored in the map information storage unitin order to correct the boundaryof the loading sitein the map dataA and then update the map dataA.

Map generation device

This sensor placement determination device is provided with an external storage device () in which traffic data, i.e. the actual paths taken by people, is recorded in a planned target area in which sensors are to be arranged, a traffic simulation observation unit () which, for candidate arrangement positions of the sensors in the target area, generates, on the basis of the traffic data, information about the passage of people through the monitoring area of the sensors, a traffic estimation unit () which, with the passage information as a constraining condition, generates candidate paths by which people might pass through the target area, an estimated error calculation unit () which, for the traffic through the monitoring area of the sensors, calculates an estimated error between the number of people passing along the candidate paths and the number of people passing along the actual paths, and an additional camera determination unit () which determines a sensor arrangement position that minimizes the calculated estimated traffic error.

Sensor placement determination device and sensor placement determination method

This invention is intended to provide a ink-jet printing device which can detect leak of ink or solvent without the exclusive sensor for leak detection and without increasing cost. An ink jet printing device for printing letter by ejecting ink, comprising, a liquid container for containing ink or solvent, a surface level sensor for detecting surface level arranged on the liquid container, a control unit and a display unit, wherein the display unit displays indication in the case where the surface level change time detected by the control unit using the surface level sensor is larger than the settled surface level change time in settled printing condition is provided for solving the problem.

Inkjet recording device

A management control device controls multiple unmanned vehicles, including the overtaking of a vehicle using an opposite lane. First and second travel permission sections are set for an own vehicle and another vehicle in a stopped state located ahead of the own vehicle on a traveling lane. A path by which the own vehicle overtakes the other vehicle is generated to include a first transition section to change lanes from a traveling lane to an opposite lane, an overtaking section that connects to the first transition section. Also included is a second transition section that connects to the front end of the overtaking section and is for the own vehicle to return to the traveling lane. The section length of the second travel permission section being set in advance is thereby shortened.
