See here my first show al local national tv covering about 4M inhabitants. We've talk about urban mobility. We made a plea for public transportation, discussing economic efficiency, reducing pollution, and several examples of Holywood stars using public transportation were given. In my city, the mayor's office wants to build a road suspended over the busiest...

I believe that all these measures can produce the expected effects because they converge in the same direction with the general public policies (even if the authorities move exasperatingly slowly in this direction). The measures will encourage the population in the metropolitan area to use their personal car less because alternatives are created for...

I choose again the city of Iasi, RO, where I live. The problems are related to the congested urban traffic at the two peak daily periods during the week and the weekend congestions at the exit to the west towards the mountain resorts. The lack of bicycle lanes, well-arranged sidewalks, the generalization of public transport lanes, intermodal parking lots at...

So urban transportation planning is not rocket science. Until we reach the moment when the critical mass of acceptance must be created for the measures that lead to the creation of sustainable urban mobility.

Technology is just a tool. Its simple implementation is far from solving the root of the problem: the well-being of the inhabitants of urban areas.

In Romania, a nation that drinks wine now even drinks beer due to marketing. I think that a person able to find his hedonic well-being can enjoy almost any mode of transport. And those looking for eudaimonic well-being prefer the train instead of a trip with their own luxury limousine. Finding a habit is done by practicing it. Driven by the neocortex (and...

The attractiveness and livability of the city clearly gives the choice with maximum score of the development of bicycle tracks compared to the minimum score that can be obtained by a highway that can only be made suspended in my city due to lack of space.

Very, very interesting. It's one of the explanations I'm looking for. So the critical mass of people who need transportation is the one who should use public transportation (obviously anyway).

I believe that the major impact of the implementation of measures to promote EV and urban transport services using EV, is the creation of the new mindset of the urban population. Reducing urban pollution and traffic congestion are the happy consequences. Marketing must focus on public transport and car-sharing. I think it is the same as for any company: the...

There have been 93 trolleybuses running in my city since 1985, but "good" management eliminated them in 2006. It is true that the suspended power lines are not aesthetic, but now the city has pollution records. Of course, electric buses are the happiest option and should not even be imported from China. But the poor quality of local governments led to the...

It is already quite clear that electric buses will make a career in our cities.

What amazes me is that in Shenzen it only charges the batteries at night. I have always imagined that battery charge management should also include partial charges at the ends of the line to extend the range.

Cleaner air in cities is a desideratum accepted by everyone but I think we must be very careful not to start on a road that closes at some point, thus becoming expensive for future generations.

Most of the cases studied can be applied, gradually in Romanian cities. I looked at the maps of several cities for this and noticed that the bike paths do not necessarily coincide with the main boulevards - they can shorten the road to POI through neighborhoods where car traffic is lower and there is room for them. In my city, in fact, there is no approved...

The area of the resulting figure is so small compared to the decagon - the average grade is 4.4.

The corruption in the mayor's office allowed the appearance of blocks of flats...

Unfortunately, my city does not even have a valid SUMP. An approximation would be that 55% use a car, 25% public transport (taxi and Uber included), 18% walk and 2% bicycle. Bicycle use has increased - the number of bicycle accidents involved has tripled from 2010 to 2016. Bicycle tracks are a bad joke. I think that the development from the point of view of...

In my city of Iasi (RO), the implementation of the urban train would solve part of the transport. The city has a T shape and there is a railway to the three main exits.

In Romania alone the capital Bucharest has a little over 2 million inhabitants, the following big cities having less than 500,000 inhabitants. There is a characteristic of cities represented by large blocks of flats neighborhoods, which results in a relatively small extent of cities.

In my city, the tram line network covers the city areas quite well. Usually cars do not go on the tram line and that is why the tram is faster than the general traffic.

Very interesting project. They covered very well the urban areas between heavyrails. They use the single line on some parts which is unique to me.

In many cases, the determination of requirements and the evaluation of alternatives are made on the basis of research whose results may be those expected by policy makers and not by the real situation.

There are few TDM measures in my city. Some streets have separate lanes for public transport but enforcement is weak and not fully respected.

There is an online application for public transport but it still does not work properly, and the number of public transport is insufficient. The major...

Hi everybody, I'm in too. We were working on algorithms during the first part of the course and now we have managed to create GreenWay as a responsive system to facilitate public transport.

Increased poverty is the main cause. In addition to work, they must also reach the places where they procure their food and other strictly necessary goods or for medical services.

Sidewalks should occupy the largest... -

First example I remember is about the metro ring in Copenhagen, Denmark. An italian company built it and they has serious issues with underpassage of old buildings such as the main rail station, an few hundred years old building without solid foundation.

Professor Banister says at one point that pollution needs to be looked at locally - to make it easier to realize.

Too few trams, too many diesel buses and undersized public transport. There is enough space on the outskirts of the city to accomodate park&ride sites to reduce the number of cars in traffic.
