Table 1: _Cont._1. Economic requirements: it has been widely reported that roads promote the economic development of a given territory, changing the mobility patterns of the population, improving accessibility and having direct repercussions on the standard of living of people who reside in urban areas [40; 59]. Therefore, it is relevant to evaluate the balance between the direct costs of the construction and indirect economic benefits generated by renovation of surrounding areas. Thus, the direct costs considered are those resulting from both the construction of the infrastructure and the future operations of maintenance and dismantling (Table 1).
