MARTINEZ, Sebastián; ESCOBAR, Diego A  e  TAMAYO, Jhonny A. Comparative Evaluation of Two Tunnel type Alternative Infrastructure from an Urban Accessibility Analysis. Inf. tecnol. [online]. 2017, vol.28, n.4, pp.157-168. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642017000400018.

In this research the impact generated by the insertion of tunnel infrastructure related with the urban accessibility conditions currently offered by the road network of the city of Manizales, in Colombia, is evaluated. Two alternatives, A and B, for connecting the southern with the northern sectors of the city are evaluated. The impact is evaluated from the calculation of percentages of saving time that the people gain with the construction of alternatives A and B, and its relationship with the population coverage by stratum. It was found that the second alternative B allows having higher percentages of saving time and benefits to a greater percentage of the medium social stratum people. However, it is estimated that the cost of its construction is 63% higher than the cost of built the alternative A. The accessibility analysis is done with the application of geostatistical models complemented with the use of geographic information systems.

Palavras-chave : population; tunnel; strata; urban accessibility; geostatistics.
