Information processing device and information processing method

A center server is an information processing apparatus communicable with a vehicle including an imaging apparatus and a user terminal of a user of the vehicle. The center server includes a data transmission request unit configured to request the vehicle to transmit imaging data captured by the imaging apparatus when a predetermined request signal is received from the user terminal, and a data transmission unit configured to transmit the imaging data received from the vehicle in response to the request to the user terminal.

Information processing apparatus, information processing system, and information processing program

A device that estimates the travel speed of a mobile body obtains a speed similarity of a travel speed associated with a road subject to estimation and a travel speed associated with each section of a map. The device also obtains an environment similarity degree of environment information corresponding to a section including the subject road and environment information corresponding to each section. A section similar to the section including the subject road is selected based on the total similarity degree, which is calculated based on the speed similarity and the environment similarity, to set the travel speed associated with the selected section as a travel speed of a corresponding time period on the subject road.

Device and method for estimating travel speed

A route generation device configured to generate a travel route of a traveling body that travels through a network configured of a node and a link, the route generation device includes a route model storage unit configured to store a route model that is data in which a frequency of travel through each link by the traveling body in a past trip performed by the traveling body is classified by destination of the trip; a trip acquisition unit configured to acquire a route starting point and a destination of a traveling body; and a route generation unit configured to extract a set of links corresponding to the acquired destination from the route model, and generate at least a part of a route of the traveling body from the route starting point to the destination based on the travel frequency associated with the extracted link.

A vehicle is provided with a driving environment information acquisition section, which acquires driving environment information, which is information on a driving environment of the vehicle. A center is provided with a driving environment evaluation section, which quantitatively evaluates the ease of traveling in the driving environment of the vehicle based on an analysis of the driving environment information acquired by the driving environment information acquisition section. A display section of the vehicle displays the result of evaluation by the driving environment evaluation section.

Travel environment evaluation system, travel environment evaluation method, drive assist device, and travel environment display device

An information processing system includes a center server, a first moving object that performs communication with the center server, and a second moving object that performs communication with the center server. The first moving object includes a submission information acquisition unit that acquires submission information related to a travel guiding, and a submission information transmission unit that transmits the submission information to the center server. The center server includes a guiding information accumulation unit that accumulates guiding information which is based on the submission information. The second moving object includes a travel guiding execution unit that executes the travel guiding for the second moving object with respect to the traveling route to the preset destination. The travel guiding execution unit executes the travel guiding using the guiding information of the guiding information accumulation unit.

Conventionally, different traffic information cannot be sent in accordance with an output reason of a request to send. According to the present invention, a request to send traffic information, which is output in response to an instruction given by a user operation or an automatically given instruction, is acquired, an output reason of the request to send is determined, and a communication unit is controlled so that the traffic information on different areas is sent depending on the cases where the output reason is the instruction given by the user operation or the automatically given instruction.

Traffic information management device, traffic information management method, and traffic information management program

A section defining method separates a road between a departure point and a destination point into a plurality of links under a predetermined condition and defines a section based on a link cost, which is an index indicating ease of travel and set for each link. The section is used to generate guide information provided to a driver of a vehicle. The section is defined by combining, among the plurality of links between the departure point and the destination point, at least two continuous links that yield a decrease in standard deviation, which is based on sums of the link costs.

Segment defining method, travel time calculation device, and driving support device

A traffic signal cycle estimation deviceis provided, which includes a travel time acquisition unitacquiring a traffic signal section travel time, a frequency distribution calculation unitcalculating a frequency distribution of the traffic signal section travel times on the basis of the traffic signal section travel times, a travel time group determination unitdetermining a first travel time group in which the vehicle does not stop at the traffic signal and a second travel time group in which the vehicle stops at the traffic signal on the basis of the frequency distribution of the traffic signal section travel times, and a traffic signal cycle estimation unitestimating cycle information of the traffic signal on the basis of a difference between the first travel time group and the second travel time group.

Traffic signal cycle estimation device and traffic signal cycle estimation method

When a vehicle passes through an intersection that is stored in a collection target intersection database and for which direction-specific probe information is collected, a CPU of a navigation device generates a plurality of direction-specific probe information (entry link, exit link, section travel time, and the like) from a plurality of unit distance section information that is collected within a direction-specific traffic information acquisition section until the vehicle passes through the intersection, an entry link traveled before entering the intersection; and an exit link traveled after passing through the intersection, and transmits these to an information distribution center.

Navigation devices, methods, and progrmas

A traffic information generation method for generating traffic information for each link includes a vehicle speed detection step of detecting a vehicle speed at predetermined distance intervals or at predetermined time intervals using a vehicle speed sensor; and a traffic jam degree detection step of referring to a specified speed and a specified distance prescribed in association with a traffic jam degree representing a level of a traffic jam and a connection determination distance prescribed in accordance with a road type to detect the traffic jam degree corresponding to the vehicle speed. When a link length falls within a predetermined range, information on the traffic jam degree corresponding to a fastest vehicle speed within a prescribed starting point distance from a beginning of the link is allocated to the link.
