Normalizing public transportation system in Santiago

and spent the Chilean Congress of Transport Engineering . There was no TV, radio, newspapers ... anything, shows virtually no convincing of the general impact of Chile's transportation engineers in solving the most serious problems in this area, now live in the country, particularly Transantiago case. But at least there blog. On Wednesday 24 October, held a forum on Transantiago, in the presence of the minister René Cortázar, Germain Correa, and academics Sergio Jara (U. de Chile) and Enrique Fernandez (Catholic University Fernández & de Cea Ingenieros ).

In this installment I will focus on the intervention of the minister (who was the first to speak, and once finished his speech, withdrew, without hearing the opinion of the rest of the panelists or the assembly, returning to the point above) . Was a summary of all the good he has done since assuming the portfolio of things to come in the short term, in order to "normalize" the public transportation system in Santiago, by the end of the year. In his presentation to shred what you mean by "normalize." Let's see:
More buses

Base for "normalization." Today, 30 more joined , and the goal is to reach 6400 by year-end vehicles, if operational fleet will certainly have a major impact on the level of service.

Renegotiation of contracts

Change from the claim payment by reference to the payment per passenger, as well as incorporating an index of contract enforcement, which every half hour measures the amount of buses that each operator has on the street, compared with what should be by contract, and on that basis, it pays. This took effect in early August and what happened was this:


With the same total number of buses in the system (about 5800), the number of buses circulating in the streets went from 4600-4800 in two days, reaching the end of September 5500. That is, a poorly designed contract, which had only fines for operators who did not meet, generating incentives not to get all the buses to the streets, because that way they saved costs (revenue claim were insured by reference) .

New Contracts have also lessened evasion:
And importantly for users, waiting times have decreased, Technology



The vast majority of buses circulating today with GPS satellite positioning system that allows to know the position of each vehicle in real time, in order to better manage the fleet, mainly to prevent two or more buses of the same line observed moving together and then a long interval without vehicles (the glue of the old "frog") . However, the central control system is not yet operational, and will not be until another year, so that in the short term will implement a control system "more human" in the words of the minister. Translating: neosapos of office, through a display of buses on the screen, may detect situations of crowding and advising drivers to regulate the intervals between passes. Not ideal but it is necessary to do so as soon as possible: better fleet management can significantly reduce waiting times before even put more buses to the system.

How to reduce travel times?
This is achieved with extravehicular pay stations (pay zones ) and segregated lanes. Of the first thing the minister did not speak, of the latter said they are making a plan to build lanes for the next few years, and in the meantime will be implemented only tracks bus, to punish motorists with cameras that invade. Seeing is believing.

How to reduce the transfers? With more
hotlines, crossing various business units. Nowadays this is not possible because the operators contract feeder lines have exclusivity over its concession area, with user forced to transfer for a journey between different units. The minister said that work is with operators to implement new routes to penetrate different areas, through a mechanism of compensation between operators to assure they will not lose money.


How to reduce overcrowding?
That looks almost impossible, as is endemic Transantiago. The system is designed to operate with 6 passengers per square meter peak, which is unlikely to change even with the projected 6400 buses, fleet will always be lower than the old system, and also will travel fewer miles per day. The only glimmer of hope is that with segregated lanes and efficient operation of stops is increased significant commercial speed of vehicles, so give them buses round, improving the frequency and thus reducing overcrowding. But that is a daydream. "Responsible for designing a crowded? I do not know. I hope that the Inquiry Committee have some light.

In short, the "normalization" of the public transport system which undertakes René Cortázar, by the end of the year, consists of:

- A fleet of 6400 buses.
- Contracts with incentives
- Part of Fleet Management (centralized system is for another year)
- New routes
- Road management through audit trails and bus only.

view of his works, management of the minister has been very good. All this goes in the right direction towards the desired "normalization." What next? The leap in quality, which is achieved with medium-term actions: Centralized control of fleet (promised), segregated roads to facilitate the movement of buses (promised), extravehicular payment stations (at least the high demand no mention), optimal pricing. Indispensable is not wasting the money go underground lines and relevant road pricing is congestion, the proceeds could be used to improve the public transport system (and London), winning all in the long term. It is the struggle to come. I hope that this debate if journalists arrive. And the minister to stay. ---
