TRanSpORTaTiOn and SaFETY in Japan

On-board flight recorders have been in airplanes for some time, and have made a significant contribution to our understanding of the causes of accidents and how to prevent them. Drive video recorders, which act like flight recorders for automobiles, have recently been brought to market in Japan and are rapidly gaining popularity in commercial vehicles, particularly taxis. These drive video reco...

Hydraulic tomography in fractured granite: Mizunami Underground Research site, Japan

[1] Two large-scale cross-hole pumping tests were conducted at depths of 191–226 m and 662–706 m in deep boreholes at the Mizunami Underground Research Laboratory (MIU) construction site in central Japan. During these two tests, induced groundwater responses were monitored at many observation intervals at various depths in different boreholes at the site. We analyze the two cross-hole pumping t...

Underground transportation system risk assessment to mitigate vulnerability against natural disasters through intelligent urban management

Quantitative and qualitative monitoring and evaluation of risk management programs will play an important role in the development of Tehran metropolitan railway transport. Considering the tectonic studies, seismic zones, land degradation and faults in north and south of Tehran, the development of underground railway lines, the assessment of the vulnerability of subway stations and the escalatio...

Dominance measuring methods for the selection of cleaning services in a European underground transportation company

Dominance measuring methods are a recent approach for dealing with complex decisionmaking problems with imprecise, incomplete or partial information within multi-attribute value/utility theory. These methods compute pairwise dominance values and exploit the information included in the dominance matrix in different ways to derive measures of dominance intensity to rank the alternatives under con...
