Sustainable urban criteria in the urban periphery of Guadalajara

The study of the growth of large cities, in the urban periphery or the peri-urban areas specifically, it relates to environmental degradation due to urbanization, if it is estimated that since 2008 more than half of the world population living in urban areas, this sector is affected as it presents overcrowding, segregation and deterioration of physical conditions, which will impact on the social aspects within localities. This great urban growth has usually developed with the lack of environmental planning.So it is necessary to include urban development, guidelines towards environmental conservation and rehabilitation of the territory. The future of cities will depend largely on the actions taken now.

The growth and expansion of cities during the last century can’t be seen without taking into account the important role they have assumed in the transport infrastructure. In Bogota have passed trough streetcar, buses and automóviles was deciding for the city, because all this periods marked a drastic change in growth morphology. This article studies the planning of Mass Transit System –MTS– Transmilenio and its interaction with the urban structure, in light of the current city planning framework. It also specifies the behavior of land use in the construction of the system first phase. One of the most important findings of this study is that there is no articulation between land and transport use system, despite the decisions taken in the ordering model. Similarly, local and intermediate planning exhibits Peak articulation.The existing infrastructure of the MTS reiterates the tendency to concentrate the accessibility in one place: the center has the largest accessibility whereas periphery fails to overcome its limitations of accessibility. While the city continued with this trend the existence of a coordinated planning system for Bogota and the ability to meet expectations of planning model is questionable, however it is something that depends not only on MTS.
