総合交通体系における自動車交通のコントロールと地域的規制の影響について

抄録

Urban transportation system expected to be reformed so as to keep necessary standards of air purity. Although successful strategy mainly depends on accelation of technical improvement of combustion engine system, the standards of it's restriction for 1978 will not be enough in the city center of Osaka where traffic density is 220 thousand Km. trips per day per square Km, 5 times higher than that of the fringe part of the city. This is the reason why transportation system should be reformed in the city of Osaka.
It is proposed in the BIG plan of Osaka prefecture that about a half of all traffic estimated in the city should be cut down to recover clean air. It is easy to lessen traffic volume technically by traffic control if there is no shock to local economy and urban activities. This diminution will change functional proportion of city core and normal form of metropolis, generally speaking, it will cause dispersion. It should be careful to disperse car traffic from city core to fringe simply without examining economic impact. Compact city might be better to save land, energy and time.
