This study clarified the actual condition of travel behavior that focused on a personal attribute and the factors influencing on that condition. As a result, this study was clarified that the elderly who are older than 85 years or who have been taken higher class of Long-term care.

Okamura","doi":"10.2208/JOURNALIP.25.1033","DOIUrl":"https://doi.org/10.2208/JOURNALIP.25.1033","url":null,"abstract":"Recently, many metropolitan governments in the world have invested significant amount of budget in the extension of infrastructures and development of new public transportation system to overcome urban transportation problems specially traffic congestion resulting from ever-growing numbers of automobiles6). Among public transportation modes, the public buses have been contributing an important role to provide access to most urban centers serving as a main mode as well as feeder mode for passengers. Thus, the improvement of existing public bus system to provide efficient public bus service is a low capital cost measure for reducing automobile dependence of the metropolitan areas. But, buses share same road with other traffic and need to stop frequently for passenger boarding and alighting. The interaction of buses with other traffic reduces their speed. Furthermore, most of urban activities and developments are concentrated around intersection. The increased activities make it an ideal location for bus stop, thereby producing heavy pedestrian flow, illegal parking etc. Also, intersection is signalized for improving safety and effective movement of conflicting vehicular and pedestrian traffic flows through the intersection at the cost of delay to traffic. As a result, buses suffer significant amount of delay at signalized intersection. Consequences are reduced speed and highly varied travel time etc. Transportation experts are exploring different alternatives ranging from space priority; bus vehicle improvement etc. to the application of advanced Intelligent Transport System (ITS) technologies such as bus signal priority, advanced communication systems, automated scheduling and dispatch systems etc.9). Since Intersection delay is one of the main criteria for evaluating bus performance, Bus Signal Priority (hereafter BSP) have been considered broadly for improving bus service performance by reducing stopped delay of buses at signalized intersection. The form of BSP system in Japan, known as Public Transportation Priority System (hereafter PTPS), has been able to reduce bus delay by providing priority at traffic signals11). With invention of new technologies in the field of intelligent transport system, opportunities for new applications are still increasing for better performance. Moreover, improvements to bus services have been considered through number of bus operation controls such as fare payment system, infrastructure improvement such as bus lanes, queue jump lanes etc. Most BSP researches are independent with these bus operation controls. Rare studies have been made considering integrated approach of bus operation control, BSP and road igfrastructures management. Combination of those elements of transportation supposed to maximize BSP effectiveness. BSP system is usually evaluated in terms of travel time benefit to bus at the cost of travel time disbenefit to cross traffic. Different combination of the above mentioned elements will have differ","PeriodicalId":115282,"journal":{"name":"Infrastructure Planning Review","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132506040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
