Classifiying streets in a medium-size city in Argentina
Posted by pertile on 21 July 2018 in English.In Argentina we discussed and finally have a new highway hierarchy criterion.
Proposal is kind of loose so we can adapt it in different situations. I used it on my city and I think is an opportunity for other to understand the process. Specially if you live in a city similar to mine.
Context: Resistencia has 300,000 inhabitants, at East there is an important satellite city Barranqueras that has 50,000 inhabitants, at Southeast Puerto Vilelas has only 8000 inhabitants, at West you find Fontana, 20 years ago a town with 10,000 people, now 40,000 people. Resistencia is a wide city with a weak infrastructure, less than 40% of its streets are paved, and there are big areas where main roads are unpaved avenues. Its checkerboard city plan has “avenidas” (avenues) each 1 km, inside that avenues there are very few avenues. It is situated on a flooding plain, there is not any rocky outcrop, average precipitation is 1200 mm a year and it never snowed. Unpaved streets are maintained with gravel, mainly when they are in a public transport route. There are so many unpaved streets that it is very difficult to have them in good conditions all the time, more difficult when it’s rainy season, so public transport streets are heavily used because it’s very common that are the only one in good conditions.
Trunk: in a medium size city we shouldn’t have any trunk street. Exceptions are roads that get here: RN11 and RN16. In big cities it could be possible we find trunk internal roads.
Primary: under our scheme they are “trunk avenues”. In Greater Resistencia they are the main access to the cities, except for Puerto Vilelas.
