An Analysis of Road Surface Condition for Transport Logistics Service in Road-linked Indochina Region

Abstract

Land transport logistics is a backbone of manufacturing and industrial centers in the road-linked Indochina region. This paper investigates the application of road surface condition analysis to benefit logistics, manufacturing and retail industries. Specifically, it intends to characterize road surface conditions based on the existence of road anomalies and other factors. A concept of a system for safe transport of products is described, and a result of an experiment is provided. The results showed that time-domain and frequency-domain analyses are necessary to detect potential causes of product damages. The time-domain analysis is appropriate for detecting shocks attributed to potholes; however, road segments with anomalies such as patch and gap showed similar characteristics with road not having anomaly. By utilizing wavelet analysis, it is shown that these road segments have exhibited different power variations in specific frequency range.
