The biggest problems of SD are the 3 major ones.
First, the streets tend to be narrow.
Too many streets that are two-way when they should be one way with one lane for traffic on the left and one for parallel parking in the right. every avenue should had been as wide as the Churchill -now Churchill ends at 27 de Febrero and from there down is Jiménez Moya, but original it was all Churchill, you still run into people that say Churchill when they are referring to Jiménez Moya-. That would had eliminated the need to make the Luperón as wide as it’s. The Defilló is basically the complete opposite of Luperón. Sone avenues are extremely short like Presidente Vicini Burgos (originally Presidente Trujillo) which basically ends almost as soon it begins. That one should had reached the Isabela River and perhaps a bridge to cross it and then continued with another name to Villa Mella. It would had been a parallel avenue, though much separated, to Máximo Gómez with that one simply being wider with three lanes in each side and a wide medin in the middle. Even Camino Chiquito and upwards into Cuesta Hermosa area should had been a wide avenue. The malecón in its estire length from the Ozama River to where it meets Luperón should had been 3 lanes in each direction with a median in the middle.
The same with the avenues east-west 27 de Febrero and Kennedy wouldn’t had to be so wide if every major east-west avenue was two-way and wider than they are. Some avenues are also too short, such as the Reyes Católicos. That one should had been as wide as Churchil and extending from the Ozama River (with perhaps a bridge connecting to Los Mina) all the way in a straight-ish line to intersect with the Duarte.The Duarte itself should had been an expressway with no developments facing the road on either side from 9 Kilometer to 25 Kilometer. A fully controlled access road. That road should had been basically like is the New England Thruway in NY.
Second, there is no rationality with the direction of some one way streets. In the US you will go through places with several oneway streets parallel to each other, but the direction of traffic alternates from one street to the other. Best example is Manhattan, no two neighborings one way go in the same direction. In SD there isn’t much rationality to this.
Third, no requirements of an X amount of parking spaces given Y amount of commercial space. Now the city is full of businesses and for most of them there is too few parking spaces. Many don’t even have parking.
