ROAD MANAGEMENT SYSTEM, ROAD MANAGEMENT METHOD, AND ROAD MANAGEMENT PROGRAM
To provide a road management system capable of predicting a degree of deterioration of a road surface property with precision high enough for practical use.SOLUTION: A road management system 10 includes: a communication device 13 that receives from a vehicle 40 measurement information 31 on a road surface property, which is measured by the vehicle 40, in association with position information on the vehicle 40 obtained when the road surface property is measured; an analysis module 21 that uses the measurement information 31 on the road surface property within a certain road section over a certain measurement period to analyze a regression line which approximately fits a time-elapsing change in the road surface property within a road section over a measurement period; and a prediction module 22 that predicts a near-future regression line for the road section, which is supposed to be obtained after elapse of the measurement period, on the basis of a transition in a traffic volume within the road section over the measurement period.SELECTED DRAWING: Figure 1
【課題】 路面性状の劣化の度合いを実用上十分な精度で予測することのできる道路管理システムを提案する。【解決手段】 道路管理システム１０は、車両４０によって測定された路面性状の測定情報３１を路面性状が測定されたときの車両４０の位置情報と対応付けて車両４０から受信する通信装置１３と、ある測定期間におけるある道路区間の路面性状の測定情報３１から測定期間における道路区間の路面性状の時間経過に伴う変化を近似する回帰線を分析する分析モジュール２１と、測定期間における道路区間の交通量の推移を基に、測定期間経過後における道路区間の近未来の回帰線を予測する予測モジュール２２とを備える。【選択図】 図１
