AB Santiago, the capital city of Chile, has seven million inhabitants in an area of 850 km2. Thiscity has a metro network with seven lines extending 140 kilometers and transportsapproximately 2.6 million people daily. The bus system has undergone significanttransformations over the last three decades. The most relevant change having beenTransantiago, the public transportation system implemented in 2007 for Santiago, Child,which combines the use of Metro and buses (BRT). Metropolitan Mobility Network (calledRed) is the latest version of the public transportation plan.This paper aims to analyze the current subway infrastructure using the continuousapproximation method for Santiago, Chile. We previously proposed a macroscopicmethodology to identify the needs for an adequate level of service in urban mobility andtransportation, and we applied it to Santiago's Metro network. Our work focuses onfunctionality and demand distribution. Santiago's demand varies spatially in volume andextension throughout the city. Using the latest origin-destination survey from 2012, wededuct the critical components in this current network structure. It is worth mentioning thatthe metro design bases its network on a ring-radial structure.With our macroscopic model applied to Santiago, Chile, we have detected infrastructureneeds in the current transit network. The supply of infrastructure should increase for tworeasons: first, to achieve balanced cost levels between users and the agency and second, toreduce subway occupations. The optimal model outcomes for Santiago define the optimalnetwork in which the system requires five rings and ten end-to-end longitudinal lines (20radial routes), including lower levels of occupation. The obtained results are a goodpreliminary solution, considering the subway infrastructure supply could be sub-estimatedin the public transportation plan.
