Thus th accssibility masur for plaig th public trasportatio should cosidr th costraits. lthough may typs of accssibility masur hav b proposd sic 197, it is ot obvious that thy ca cosidr th spac-tim costraits causd by public trasportatio. This study rviws th applicability of currt accssibility masurs i trms of plaig th public trasportatio ad shows that thy ar ot suitabl. Th w accssibility masur is dvlopd basd o spac-tim prism. lso, w dmostrat th umrical xampls by which w masur is usful for plaig public trasportatio. 553
