Park Avenue

May 21, 2010

Avenue [ˈævɪˌnjuː] from the old french arrival, has eventually got a different meaning in english, as well as in current french, due to the current usage we give to it nowadays.

Here after is a very simplified history of it:

XVIII century

At the eventual difference of other roads or streets, avenues were usually work of urban planning, and primarly designed as radial promenade at the edge of the city with function to great in a ceremonial way the arriving visitor

XIXcentury

Though that not matching to the original vision, the primary promenade function is still well respected.

The same location at the turn of the century. The leisure aspect of the promenade is still well alive

XX century

The advent of the automobile and other social change will involve deep cultural shift:

  • Urban people will eventually prefer spend their free time elsewhere than lingering on the street becoming less pleasant due to the surrounding roaring motors and gas smell (we don’t speak to much pollution those day).
  • the free space is then occupied by the new mobility device

With the advent of the automobile, the promenade change of function! (it is still Avenue du Mail, lately renamed Mail Francois Mitterrand, Rennes France)

XXI century

Another relative cultural shift appears in the 80s, eventually learning of the american experience: it appears very apparent that the adaptation of the European city to the car has no future: and a better use of the scarcely city’s available real estate need to be devised. the LRT, trams in Europe, will be part of the solution, and the large French avenues, will be ideal Right of Way candidate. The vision of the future century is then eventually represented by this artist rendering:

One will note, it is pretty seldom to see modern tree lined trams, eventually for the following reasons:

  • the tree roots system could compromise the integrity of the trackbed
  • the tree branches could interfere with the overhead wires
  • the falling tree leaves could grease the rails, compromising the acceleration/braking capabilities of the train

In the Strasbourg F-line case, those aspects are mitigated by the integration of the bike path along the tram ROW. the integration of the bike path is an addition to the late LRT project.

Obviously, the vision is a significant progress on the current situation, in the sense it returns to a pleasantly greenish aspect of the avenue.

The park and ride model

Where we should not give more credit to the french than they deserve is here:

  • In most of the case the space allocated to the automobile traffic is not compromised, and the Strasbourg example shown above is basically no exception to the rule: while that the parking space is removed at the benefit of the trams, there is no reduction in automobile traffic lanes benefiting then of a freer flow, since not impeded by car looking for or negotiating parking spot
  • there is no increase of space for pedestrians, and the leisure and social interaction aspect, like lingering on the street, is not part of the picture either

The removal of parking space could be considered as a progress, but usually, a french tram projects barely means reduction of parking space either, but rather relocation of it according to the well known park and ride model.

The picture below feature one P&R in Bordeaux having 603 stalls [6], more than at the Canada line Bridgeport one [7]. Bordeaux has 14 other structures like this along its 3 trams lines…

One can clearly suspects that the motivation to introduce trams in the french cities has not been to challenge the general car centric culture, but was more guided by more pragmatic space constraint requiring a P&R model in order to preserve good vehicular movement on the city arteries and accessibility of the city to an ever greater number of people, including by car.

In that aspect, it has been a more successful model than the US one, eventually due to the greater scarity of

  • downtown parking stall
  • road access

and,

  • the preserved heritage specificity of the European cities could have contributed to maintain the attractiveness of their downtown in despite of access impediment
  • the short length of the European trams line, typically not venturing much farther than 5km from he town center, allow for short trip time, in despite of relatively low average speed [4], the later allowing good integration in the urban fabric

All those factor, in addition of social one going beyond the scope of this post, could have saved the middle size European city to know the fate of their American sister cities, in term of Downtown life.

But, if one considers the public transit market share in 14 french urban areas with LRT; 11% (for weekday trip) [8]; it is hard to speak of a successful strategy, to be emulated.

At the end of the day, the avenue original vision, which cheer size was to provide “park” space for people, devoided to be “park” space for transportation device, has not been restored. Indeed it is now used to “segregate” space according to transportation modes (in a vision where “lingering” is also a “commercialized” activity at the benefit of the sidewalk coffees).

It is a progress on the dictatorship of the automobile reign, and it is possible that the LRT has been an ingenuous tool to legitimate the displacement of the cars toward the outer edge of the city, but is the result the most efficient allocation of the city surface space? or in other term, is it the best we can do?
