This is the million dollar question for sure. As an engineer living in the country I too pay attention to detail and the condition of infrastructure and buildings. It is very rare to find ANYTHING, ANYWHERE in this country that is maintained in accordance with normal conventions. This could be one of the few examples where the concept of "paying attention to detail" is followed or just another example planned obsolescence.
As far as the transport unions as long as the rest of the country doens't get a metro these bozo leeches won't be going away anytime soon.
Problem is basically that gov micromanages too much and therefore is grossly inefficient at it too.
Let me tell you how this will be reversed for good:
Take any bridge (and I mean any in use today in the DR) and place a well formulated contract up for bids from the private sector; once a good bidding is done, the contract is awarded to x company that will in turn place a toll on a single way (one heading) of that bridge.
The toll will be subjected to strict for profit percentages, taking under consideration the costs to maintain the infrastructure by the contracted company. In effect it is in the contracting company's best financial interest that the bridge is fully operational and infrastructural sound.
Instead of single companies bidding for single bridges, they'll be bidding on sets grouped to a region. The same will play out with major intercity highways, which will be partitioned by spans.
For the local streets in cities and municipalities, there'll be a totally different approach. This level will require that vehicles registered within a city/municipality's legal perimeter, will have tags that includes a monthly surcharge (over that from the gov) paid yearly to support the street maintenance by the local authorities directly. This fund will be locked to the dept that deals only with street's infrastructure maintenance only, avoiding misuse of funds by the City/municipality in other things. The funds will be deposited into a bank account with interest bearing rights, as funds will not always be depleted to repair/maintain the streets in the same level of revenues.
Each tag will bear the City/municipality it pays revenues to in it. The lesser cars registered in a municipality, the lesser needs for street's maintenance is concordantly needed.
Same will be done with all infrastructures out there today.
About the rust tin cans for cars the sindicatos use today, we'll later enforce safety protocols in that sector that will render 90% of those things unsafe and revoke any permit to transit in a street, let alone carry passengers in commercial terms.
If sindicatos are planning to continue to live in the DR, they'll need to evolution with the times. They'll be required to upkeep a float of vehicles that will be strictly inspected and supervised, including a limit of time in service for each unit as well. Think of them as private bus operators, only that they'll own their buses and depots. The gov will provide each sindicato with lines of credit backed by the gov from independent sources; which way they'll be able to purchase and operate the units (only the ones pre-approved to enter service and not what they want) or have them embargoed and added to the gov's float of vehicles if the loan's payment is defaulted at any given term. The contract with the sindicato will be legally voided and open bidding for the route from other sindicatos accepted within a certain period of time.
No more cars for public transport, safe for private taxis and clearly yellow cabs.
There's absolutely no interest to remove all the working men and women from the sindicatos in the streets. What we need is to place strict rules and proper vehicles that can provide the public the service they so much need.
The sindicatos will be able to share the revenues from fares after payment of the loans are made each cycle. They'll be independent operators that must answer to contracts and public law as well.
Just like the feeder buses operated by the gov, the sindicatos will have exclusive lanes during rush hours and heavy traffic that results in congestion. The same devices used for the gov buses (cameras) will be used on their buses as well. A bus driver training program will be in place to re-train the much maligned syndicated drivers.
