The aim of this paper is the development of an accessibility estimation method as a transport policy assessment tool based on the state of the art of the accessibility concept and measurement techniques, and available information directly related to socioeconomic data, transport demand and supply characteristics for specific areas of Bogotá. Study areas and indicators are defined in order to determine relevant relationships between transport and access to opportunities for individuals with specific socioeconomic characteristics and present mobility conditions. In addition, evaluation of restricted travel budgets scenarios defined both by the standard transport theory and individuals is performed. [ABSTRACT FROM AUTHOR]
