The more expensive fuels become, the higher the cost of traffic obstructions. Expensive in themselves, in view of the great loss of time they cause, they imply a monetary cost in terms of the fuel consumed during the increasingly prolonged periods that the vehicles remain immobilized.
So far the solution attempts have been ineffective. And the worst part is that there are no effective correctives in sight in the foreseeable future. Actually, judging by what has been happening, it is logical to expect things to get worse.
Essentially, it is about accommodating a growing number of vehicles on roads whose dimensions are fixed. It is somewhat similar to trying to put more and more objects into a suitcase. Eventually, if the suitcase cannot be expanded any further, some things would have to be taken out of it so that others could be put in their place. Or you should stop the increase in the number of objects, and keep only those that are already inside.
As far as traffic is concerned, the substitution would not achieve its purpose if it consists of replacing dilapidated units with new units, since their number would not vary, and it would be small compared to the rate of increase in the total number of vehicles. And stopping the increase would undermine sales and fairs, affect collections and discriminate against those who do not have a vehicle. The substitution of individual transport for collective transport seems to be a promising mechanism, but we would be fooling ourselves if we believed that it could be applied in the short term and without large investments of resources that we do not have at our disposal today.
The changes in the direction of the tracks are only a palliative, diminished because they have led to more vehicles parked on both sides. The planned construction of parking lots can help, given that a large part of the roads are occupied by parked vehicles, provided that strict measures are taken to prevent the streets from being used for that purpose.
