How to Add Bike Lanes Without Messing Up Traffic Flow: An Animated Visualization

How to Add Bike Lanes Without Messing Up Traffic Flow: An Animated Visualization | Ambiances, Architectures, Urbanités |

As bike lanes get added to streets around the US one common concern keeps arising: how will this affect congestion? Narrowing roadways by including bike lanes seems like it would clearly increase car traffic, but data from New York City suggests that when done correctly, adding bike lanes can actually speed up traffic flow. Since 2007, the city has added over 30 miles of protected bike lanes.

The solution most commonly used? Road diets.

A road diet is commonly described as “removing travel lanes from a roadway and utilizing the space for other uses and travel modes.” There are many implementation strategies, but when done correctly they provide smoother traffic flow through neighborhoods and better safety for everyone using the road...

Complete Streets: Designing to Create Connectivity at our Public Spaces

Complete Streets: Designing to Create Connectivity at our Public Spaces | Ambiances, Architectures, Urbanités |

A street shouldn't just be about transportation, but also about civic definition and social and commercial interaction.


There is no better place to start using land more efficiently than with our streets, our most plentiful and visible parts of the urban commons. The recent "complete streets" movement has made a terrific contribution to getting our streets right, by insisting that they be designed so as to accommodate all users.

Connectivity is hugely important to a sustainable street network to encourage walking and shorten driving trips by making destinations more convenient. The pedestrian experience should be safe and enjoyable, and should be so perceived.


Other design elements to help turn streets into worthy places are:

Sidewalks with real curbs;On-street parking ;Street trees;Storefronts with elements that shelter pedestrians such as awnings, arcades, and colonnades;Buildings with windows and "other signs of human occupancy such as porches and balconies" for "eyes on the street";Design appropriate to safe motor vehicle speeds.

Five Cities Show the Future of Walkability

Five Cities Show the Future of Walkability | Ambiances, Architectures, Urbanités |

To walk in our cities is more than just a simple act of transport. Walking represents an appropriation of urban space for daily life. It means being an active part of the urban environment by learning, understanding and shaping the city on a personal level. Walking is one of the most democratic and equitable ways of getting around, but it’s also one of the ways most linked to factors outside an individual’s control, like social or physical abilities and the presence of infrastructure to walk comfortably and safely.

These are the factors that define walkability, which refers to how safe, convenient, and efficient it is to walk in an urban environment. Walkability has a direct impact on urban residents’ mobility, as the term is often used to communicate how likely the average person is to choose walking over other modes of transport in a given area...

Bien vu les vertus de la marche à pied urbaine pour l'appropriation du territoire par ses habitants, quelques exemples de Helsinky à Hambourg

Catherine Bossis's curator insight, April 30, 2015 5:59 AM

Je ne suis pas Bordelaise, ni au fan club du Maire de Bordeaux, je me déplace beaucoup en France. Ce week-end j'ai marché à Bordeaux et deux choses m'ont sauté aux yeux : 1- il y a des bancs (propres et agréables) partout en centre ville. On peut se reposer très facilement, ce qui facilite grandement la marche surtout des personnes à mobilité réduite (comme mes ados un peu paresseux !). 2- j'ai vu des enfants faire du vélo, ce que je ne vois pas à Toulouse par exemple où cela reste très dangereux de circuler en vélo (ce que je pratique chaque jour).  Dans d'autres collectivités Françaises j'observe un retour en arrière sur la piétonisation et la cyclabilité et c'est bien triste.
