“An experiment” that “can begin to give some advantages connected to the use of public transport” but that “does not weigh too much on the coffers of the transport company and therefore of the Municipality”. Enrico Musso, Professor of Transport Economics at the University of Genoa, who as director of the Italian Center of Excellence on Logistics, Infrastructure and Transport, oversaw the Sustainable Mobility Plan for the city, thus explains the project to Adnkronos, active in city, starting from 1 December and until the end of March, which provides free transport on the underground, at certain times, and all day on vertical systems. Genoa is the first Italian city to implement an experiment of this type, attentive to sustainability and to contain the crowding on public transport “For now it is not about buses. Then, if the mayor’s idea works, it is to proceed by successive segments” , announces, referring to a larger project of Marco Doria’s administration, which has appointed him as coordinator of sustainable urban mobility. “We have been working on it for some time, the real problem is the resources. Whichever segment of gratuity is introduced, you give up a certain slice of revenue – underlines the teacher – We had to start with some not excessively expensive tasting with an experiment”. The measure consists of two parts. “Genoa has a very high number of vertical lifts, lifts, funiculars, racks, cable cars, about 25, all public – he remembers – They are used by all those who live on the heights, those hilly neighborhoods where parking is impossible. This seemed the measure that would have given the best ratio between utility and cost: we are talking about 200/250 thousand euros for 4 months of experimentation. The same is the cost, in terms of lost revenues, of making free use of the subway during the so-called ‘soft’ hours, 10-16 and 20-22 also with the function of spreading the traffic and avoiding the overcrowding of vehicles “. The meaning of the initiative, Musso further clarifies, “as foreseen by the urban sustainable mobility plan is to transfer mobility quotas from private traffic to public transport, with evident consequences in terms of environmental costs. But since environmental costs are external costs if we leave to choose people based on their living costs, travel times and above all comfort, it is very unlikely that they choose public transport. You have to give them an incentive that in this case, in the short term can be represented by measures like this “.” For the medium-long term Genoa has started a real revolution in public transport with a series of measures that will be much more incisive when they are completed. in a rather short time that it begins to give some kind of advantage connected to the use of public transport “, he reiterates. Looking at the numbers “the total revenue of the transport company in the city on an annual basis is 60/70 million if we did everything for free, we would have to find that figure. Instead, the experimentation is worth about a cent, between 500 and 600 thousand euros”. , assures Musso, “these are measures that frighten the administrators a little, they open holes and there are many things that can alarm”.
