The Hierarchy of Urban Transport Networks

At the level of premise, most experts agree that, in urban, traveling public wants so-called ex-ante demand do not get to be fulfilled by transmission system exploit, so-called ex post demand level is lower desires the reasons are complex, but the general idea is the network that descends satisfied offer between the two categories of demand. In this material is presented a mathematical model for evaluating the quality of urban transport networks, the proposed hierarchy is determinate by the post central level approach of ex- ante demand of ex -post ideal. The exploitation of urban passenger transport has led to a custom on improving service: It is believed that multiplying the number of routes or vehicles number will bring the ex post level to ex-ante levels. In this paper is demonstrated that this desideratum is impossible to achieve. Like conclusions: numerical values for ex-ante demand near to ex-post demand; a relatively simple instrument, but consistent, to prioritize urban transport networks; a procedure for determining the profitability of “breakthroughs” in constructive structure that would reduce the distance by setting the limit up to which may increase the fare.
