The city recently implemented an ambitious campaign to reduce car traffic, improve public transit, and encourage walking and biking.
In the last five years, sidewalks have been widened, bike lanes striped, and trees planted across the city. A new light rail line is being constructed around the periphery, and driving is actively discouraged.
On 25 miles of Paris's most congested avenues, medians have been added to provide a dedicated lane for buses, bicycles, and taxis. Furthermore, bus service was made more reliable and convenient by the addition of real-time service information at every shelter.
The City's Transportation Plan bans the construction of new off-street parking and will eliminate all free parking. By 2007, 3,500 on-street parking spots will be eliminated.
The decrease in cars allows for more activities, such as the Paris Plage, a highway-turned-beach along the Seine during the summer.
In neighborhoods throughout Paris, the Mayor's office has planned traffic calming improvements, as noted in this sign.
