Disaster resilience in transportation: Japan earthquake and tsunami 2011

Purpose – The purpose of this paper is to examine the transportation organizational service provision and travel behavioral responses after the March 2011 disaster in North East Japan. This research aims to identify the areas for capacity building in transportation to support resilient built environments. Design/methodology/approach – A case study approach was taken to examine the transportation organizational service provision in one of the most devastated communities after the 2011 Japanese earthquake and tsunami. Data on post-disaster transportation arrangements were collected from local newspapers, desk reviews of reports by transportation operators and the local council, semi-structured interviews with local council and community groups, and a residents’ questionnaire surveying travel behavior. Organizational responses were analyzed by: the pre-disaster phase, the emergency phase, the rebuilding (temporary settlement) phase and the recovery (permanent settlement) phase. Findings – Transportation dema...

Actual situation analyses of rat-run traffic on community streets based on car probe data

Lowering of so-called “rat-run” traffic on community streets has been one of significant challenges for improving the living environment of neighborhood. However, it has been difficult to quantitatively grasp the actual situation of rat-run traffic by the traditional surveys such as point observations. This study aims to develop a method for extracting rat-run traffic based on car probe data. In addition, based on the extracted rat-run traffic in Toyohashi city, Japan, we try to analyze the actual situation such as time and location distribution of the rat-run traffic. As a result, in Toyohashi city, the rate of using rat-run route increases in peak time period. Focusing on the location distribution of rat-run traffic, in addition, they pass through a variety of community streets. There is no great inter-district bias of the route frequently used as rat-run traffic. Next, we focused on some trips passing through a heavily used route as rat-run traffic. As a result, we found the possibility that they habit...

The disaster prevention awareness of foreign residents and disaster management of organizations for foreign employees

Japan is known to have many natural disasters occurrences, especially in recent years, the seismic hazard named “Nankai-trough Disastrous Earthquake” of magnitude 9(M) was predicted and will have caused huge damages. Therefore, disaster management should be well planned and executed to ensure minimal amount of victims and damages from disaster. However, foreign residents are mostly vulnerable and ill-equipped to face such consequences compared to Japanese residents, especially when there is limited information available for foreigners presently. As the influx of foreigner migration has been steadily increasing annually, it is vital for disaster management to be compulsively planned to cope up with the great variety of foreigners’ needs from diverse backgrounds accordingly. The purpose of this study is to comprehend foreign residents’ disaster prevention awareness, in order to provide a more effective information provision on disaster management, so as to help improve their disaster prevention awareness. T...

Impacts of monetary incentive measures on the acceptability for intelligent speed adaptation (ISA)

In Japan, Mandatory Intelligent Speed Adaptation (ISA) or Voluntary ISA could be a new paradigm for urban driving speed management such as traffic calming in community streets, once it is widely disseminated. This study aims to analyze the impacts of various monetary incentive measures and individual attributes on the acceptability for several ISA installation. We conducted a stated preference (SP) surveys for the subjects who had attended in a 5-month Advisory ISA field experiment. Then we applied disaggregate model analyses to the response data. The main results were: that the acceptability for Advisory ISA is highest followed by Voluntary ISA and then Mandatory ISA; that the acceptability for ISA that operates only on community streets is high; that the acceptability becomes higher as the age of the subjects becomes higher; and that the acceptability becomes higher as the amount of the monetary incentive becomes greater, but the marginal effect becomes lower. In conclusions, the monetary incentive meas...
