摘要： PROBLEM TO BE SOLVED: To search for a route by reflecting know-how of easiness of traveling or the like included in probe data collected from many vehicles over the whole route from a starting place to a destination.
SOLUTION: A center device detects a main branch node by a main branch node detection part from probe data received from an on-vehicle terminal device. A probe data dividing part divides the probe data into probe slices with the main branch node. A route dividing part divides an initial route generated by an initial route generation part based on the designated starting place and destination, and a derivative route generation part generates a derivative route formed by replacing the divided route with the probe slice. A route selection part scores and selects each derivative route, and provides a recommended route to which know-how of easiness of traveling or the like included in the probe data is reflected.

摘要： PROBLEM TO BE SOLVED: To complement data on traffic information of a road link having no present state data with high accuracy by use of data on a road link having present probe traffic information even when a small number of the road links collect the present probe traffic information. SOLUTION: Principal component analysis is applied to probe traffic information collected in the past in each area, and a base showing high correlation of the road link wherein the present probe traffic information is collected is selected from a base related to the traffic information calculated for a link group in the area. Composite strength of each the base related to the present probe traffic information is calculated from the selected base for the link group by projection. By linearly composing the respective bases with the calculated composite strength as a coefficient, estimated traffic information in the link group is calculated, and the calculated estimated traffic information is set as complementary information with respect to the link having no present probe traffic information.

摘要： PROBLEM TO BE SOLVED: To provide a traffic information system, capable of delivering, in the event of an emergent event such as traffic accident or road repairing, information for the range and degree of its influence on circumferential roads to an on-vehicle terminal device.
SOLUTION: Upon receipt of emergent event occurrence information, traveling histories of passing through the emergent event point are extracted from the past traveling histories of probe cars. Based on the extracted traveling histories, traveling frequencies of road links on which each probe car traveled are determined with respect to all the extracted traveling histories, and passing frequency information is created by normalizing the traveling frequency of each road link with the total number of probe cars which passed through the road link with the emergent event, and delivered to the on-vehicle terminal device. The on-vehicle terminal device displays the degree of influence in each road link based on the passing frequency information.

摘要： PROBLEM TO BE SOLVED: To reduce the processing load required for detecting resolution of an emergency event in a traffic information center in an emergency event detection system.
SOLUTION: The traffic information center generates, in conformation to each emergency event, an emergency event resolution determination condition for determining resolution of the emergency event on a vehicle side and provides it to each vehicle. Each vehicle determines, based on the received emergency event resolution determination condition, resolution of the emergency event based on traveling history information of the own vehicle, and reports, when the emergency event is determined to be resolved, that effect to the traffic information center. The traffic information center performs a final decision that the emergency event is actually resolved from the emergency event resolution detection result obtained from a plurality of vehicles, and reports the resolution of the emergency event.

摘要： PROBLEM TO BE SOLVED: To provide a traffic information system for detecting a sudden phenomenon such as a traffic accident or work from traffic information of a peripheral road link.
SOLUTION: Principal component analysis is performed about a link group as a detection target of the sudden phenomenon by use of the past traffic information to obtain restoration traffic information of the past traffic information from an upper base related to the traffic information of the calculated link group. Residual statistical traffic information is created from a residual error between the past traffic information and the restoration traffic information thereof. Restoration traffic information of the present state traffic information is obtained from an upper base to the present state traffic information. A residual error between the present state traffic information and the restoration traffic information, and the residual statistical traffic information are compared, and it is decided that the sudden phenomenon occurs when the residual error of the present state traffic information is larger.
