Bonjour, Minato Ku. Quel bon collection du photos metro!

I had a question about Paris and it's transit structure.

I know it is a very dense city compared to US cities, but I read that like Los Angeles, not everyone goes downtown or in the center to work, that they have centers in the outer arrondisements and the suburbs (La Defense) and that the system accomodates that with things like the Translinen.

Where are those centers like La Defense at in Paris or le petite couronne du Paris?

La Défense is in inner suburbs (Petite couronne)
It is right that in Paris the majority of jobs are located in suburbs but the city is still centralised with a strong central area.

Private employement in the economic clusters in Paris metropolitan area.

Stations Picked, Huge Automated Transit Project for Paris is Closer to Realization

http://www.thetransportpolitic.com/w...rand-Huit1.jpg

» Three intersecting lines will serve mostly circumferential routes around the Paris city core, providing fast trips to a currently under-served clientele.

In the Western World, the most significant rapid transit project currently being contemplated is Paris’ 96-mile Grand Paris network that would extend brand-new automated rapid transit lines across and around the region at the eye-popping price of more than twenty billion euros. If adequately financed, it would be a huge undertaking designed to speed travel between locales now at the periphery of the region’s fast transit network, spurring housing and population growth in the metropolitan area’s suburbs.

Announced more than a year ago by conservative President Nicolas Sarkozy, the program has no assurance of being completed. While regional authorities are currently constructing dozens of miles of new light rail lines, several busways, and a few metro extensions, almost all in the inner suburbs, the national government’s program has yet to be funded thanks to its extraordinary cost. The RER regional rail program, the last major transit program conceived for the French capital, radiates fast trains from the city core and was conceived in the 1960s, and little has happened since. Continuing the current situation could mean decades of only minor improvements in mobility for the nine million people living just outside the walls of the City of Paris.

Yet the Réseau Primaire de Transport du Grand Paris (primary transport network of greater Paris) may be coming to life. This week, the government opened public debate on the project, revealing the extensive studies it has completed on potential alignments for the rail corridors, including proposed station sites. And the Sarkozy Administration has committed to €4 billion to the Société du Grand Paris, the semi-autonomous organization that will build the project and invest in eight major development sites that will have prime access to the network.

If the program is approved, the Société would take on 40 years of debt financing to sponsor the €21.4-23.5 cost, to be paid back mostly through deals made on real estate in station areas.

The project would encompass 155 km (96 miles) of new lines that would be added to the existing automated 5.5-mile Line 14 Metro that currently runs along a southeast-northwest route through Paris. Three routes would be offered: a 50 km Blue Line from Orly Airport to Charles de Gaulle Airport, via the existing Line 14; a 75 km Green Line from Orly Airport to Charles de Gaulle Airport, via the La Défense financial district west of Paris (with 21 km shared with the Blue Line); and a 60 km Red Line from La Défense to Le Bourget Airport, via the southern and eastern suburbs. Commute times for suburban residents hoping to reach destinations outside of Paris will be decreased significantly, with average train speeds a very respectable 40 mph thanks to few stations (give or take 40, depending on the final alignment chosen) and very high frequencies thanks to automation. At peak hours on some segments, trains will arrived every 85 seconds.

Unfortunately this grand project is quite bad as it serve some empty area, avoid some densely populated and key area.
It does not the provide a good numpber a interchange in suburbs and the has too few stations.

The Arc Express project of the Regional government is better.

Geez, the T1 tram vehicles look as massive as the light rail vehicles here in the 'States.

T1 tram vehicles are smallest rolling stock of Paris tram network.
Well less massive than the light rail in the state.

By 2014 the station will be completly rebuilt.

Nanterre Université was build in 1972 as a temporary station before the construction of a new underground station, cancelled later.

A more complete view of the Arc Express subway line ring project.
It show the different route that could use this line. (Of course if it is build only one by would be used).

What kind of trains are they planning for the ArcExpress? RER or Metro?

:previous: metro but wider than the other parisian metro rolling stock.

See the speed of the reverse.

Fast indeed. Did the motorman really run the length of that train that quickly?

Not it is drvierless, the reverse doesn't need a driver.
At the end of the video, we see that the driver exiting his cabine at the end of the train.

The first driverless trains could run by June 2011 on passengers service.
During a period of the several month the trains with drivers will coexist with driverless trains.
