The accident patterns also is not taken into account

The vélopartage is as an effect of mode or real progress Read a recent study of the Commissioner-General for sustainable development, the Vélib ', bike' v, Cyclic and other Bicloo are profitable investments. This interdepartmental structure for its statisticians encrypt the cost benefit of this new mode of urban transport.

Isabelle Cabanne, who coordinated the study from the figures available for 2008, the French systems 20 has an overall cost estimated at 100 million per year. It includes the investment of the French Park of 32,000 bikes but also its operating costs. According to the authorities responsible for transport (GART) group, the average annual cost of a bicycle represents 2,000 to 3,000 euros. In Paris, where Vélib' affected undergoes many of deterioration, this figure would be around rather 4,000 euros.

An approximate encryption

For the user, the Office considers the benefits of these systems to EUR 110 million. The benefits are not lacking, but their encryption remains approximate. Scholarly calculations assessed gain time of eight minutes of daily transportation users, that experts usually valued at EUR 80 million.

Second argument of the bike, it releases the place in the transit and roads. With 120 million kilometres, the small Queen would avoid 70 million kilometres of congestion, or 28 million euros in savings for the company. The environmental benefits are known: noise reduction, local pollution or greenhouse gas emissions. However, the evaluation of these negative externalities does not exceed half a million euros. Encryption of profits is not exhaustive. The positive impact of cycling on health is too difficult to make it clear that there is consensus against cardiovascular disease or obesity.

The accident patterns, also, is not taken into account. Several European studies have shown that the risk of accident for each cyclist drop when the Park becomes bigger. On the contrary, they consider that a cyclist is more vulnerable than a transit user or a motorist.

It is clear from the study that the advantage of these systems increases with their size. The largest vélopartage operations thus know 5 rentals per day use rates when smaller mired in 2 locations.

The "shared bike" is defined by a system of public provision free of charge or pay. It is in La Rochelle, it appears for the first time in Europe in 1975.

Strasbourg in head

The latest figures provided by the Club of cycling cities association, there are now 25 systems of bikes shared France spreading evenly on French territory. Moreover, 80 of agglomerations of over 500,000 inhabitants adopted it.

The system of shared bikes is not however the unique model for the promotion of urban cycling. Services lease or loan and the parking stations still dominate in absolute value. But the vélopartage is the one who has experienced the strongest growth these past three years. In 2010, Strasbourg will direct its rental system to this formula. The Strasbourg hold first place in the French urban cyclists as they realize 10 of their movements, from 2 to 3 for the French average. The objective of the urban community of Strasbourg is to offer 3,500 two-wheelers in over 60 points.
