本研究では、歩行者の方向感覚を阻害する存在として、地上と地下を繋ぐ階段での進行方向の回転に着目した。地上から地下への階段の曲がり数とその後の地下歩行空間における歩行者の方向定位と経路探索時への影響を分析するため人の空間認知プロセスにおける視覚情報について具体的に検討した。階段通過時の進行方向の回転をシミュレートした室内実験を行った。被験者に対し情報提供を行い、それらの経路探索への影響を分析したその結果、階段の曲がり数が要因となって方向定位と経路探索が困難になった。また、情報提供内容によって方向定位を改善できる可能性を示唆した。

The purpose of this study is to consider the possibility to apply a third-sector railway “Furusato-gingasen”, for improvement the service level of transportation between central and eastern Hokkaido. Most of the lines which were separated from JNR (Japan National Railways-the forerunner of Japan Railways) were reborn as thirdsector railways. But the plans of management to maintain the minimal level of transportation infrastructure had not been discussed enough. The environment of transportation in rural areas is expected to become more difficult after the relaxation of restrictions on supply and demand adjustment in mass transit. The economy of Hokkaido Chihoku-kogen Tetsudo Company, the owner of the “Furusato-gingasen”, is not healthy just like other third-sector railways in rural areas. New countermeasures should be estimated and tried at this critical turning point.The first step was test calculation of the high speed improvement utilizing the “Furusato-gingasen”. We had a result that it would cost approximately four billion yen. We also analyzed the attitudes of the residents in Kitami and Abashiri who usually use railways. As the result of the simulation by a modal choice model, it was clear that application of the “Furusato-gingasen” would be able to raise the share of railway transportation between Sapporo and cities in eastern Hokkaido.
