NETWORK LEVEL PAVEMENT EVALUATION USING SIMPLE ROAD SURFACE MEASUREMENT TECHNOLOGY AND SPATIAL INFORMATION ANALYSIS

Abstract

 In Hokkaido, there is concern about the reduction of riding safety and comfort on cracked road surfaces on bicycle paths. However, the most important factor that has not received enough attention is the understanding of the occurrence of pavement damage and maintenance management in bicycle paths. In this study, a network-level pavement evaluation method was developed by incorporating a crack type identification method for bicycle lanes into a simple road surface condition measurement technology and using spatial information analysis such as scenario analysis and hotspot analysis. We applied this method to the Tokapuchi 400 and found that in the scenario where repairs are carried out according to conventional management standards, the cracks in the bicycle lanes are eliminated in about 5% of the sections. It was also found that the longitudinal cracks in the pavement are continuously distributed over a distance of about 3 km in the mountainous areas and the plains.
