ROAD SURFACE CONDITION MEASUREMENT SYSTEM, ROAD SURFACE CONDITION MEASUREMENT METHOD AND ROAD SURFACE CONDITION MEASUREMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a road surface condition measurement system and a method and a program thereof related to a technique for obtaining information useful in highly reliable road maintenance, which perform statistical processing of large-scale data (such as positional information and acceleration information) automatically acquired by using sensors and the like of road users and thereby obtain information useful in highly reliable road maintenance.;SOLUTION: A road surface condition measurement system, and a method and a program thereof are provided, in which: upon receiving data indicating a vehicle position and a traveling road surface property of a vehicle traveling section and road section data 132 indicating a road section, an estimated position and an estimated road surface property value in the traveling section is calculated by using the data indicating the vehicle position and the traveling road surface property of the vehicle traveling section; common portions in the traveling section that correspond to the road management section having road information comprising a position and a direction for each road management section, are identified by using the estimated position; an estimated distribution of all estimated road surface property values that correspond to the common portions are calculated; and a distribution of the road surface property value is obtained from pieces of data indicating the traveling road surface properties which are obtained from a plurality of vehicles.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
