A GIS-based risk assessment for hydrogen transport- a case study in Yokohama city

Abstract

This study proposes a method of assessing the risk of hydrogen transport via road considering spatial features of a transport route, based on a geographic information system (GIS); a case study of Yokohama, Japan was considered in the assessment. The risk determined by multiplying the frequency of accidents with their consequences was estimated using road segments constituting the entire transport route. The effects of road structure, traffic volumes, and population information were reflected in the estimation of the risk for each road segment by using GIS. In the case study, the risks of transport route were assessed at an acceptable level under risk criteria. The results indicated that the risks fluctuated according to the road segments, indicating that spatial features of a transport route significantly affect the corresponding risks. Analyzing this importance indicates the transport routing to avoid high risk road segments as countermeasures.
