Dead end (street)
A dead end, also known as a cul-de-sac (ˈkʌldəsæk,_ˈkʊl-, from French for 'bag-bottom'), no through road or no exit road, is a street with only one inlet or outlet. "Dead end" is also understood in all varieties of English, but the official terminology and traffic signs include many different alternatives. Some of these are used only regionally. In the United States and other countries, cul-de-sac is often not an exact synonym for dead end and refers to dead ends with a circular end.
Bicycle-friendly
Bicycle-friendly policies and practices help some people feel more comfortable about traveling by bicycle with other traffic. The level of bicycle-friendliness of an environment can be influenced by many factors including town planning and cycling infrastructure decisions. A stigma towards people who ride bicycles and fear of cycling is a social construct that needs to be fully understood when promoting a bicycle friendly culture.
Traffic calming
Traffic calming uses physical design and other measures to improve safety for motorists, pedestrians and cyclists. It has become a tool to combat speeding and other unsafe behaviours of drivers in the neighbourhoods. It aims to encourage safer, more responsible driving and potentially reduce traffic flow. Urban planners and traffic engineers have many strategies for traffic calming, including narrowed roads and speed humps. Such measures are common in Australia and Europe (especially Northern Europe), but less so in North America.
Grid plan
In urban planning, the grid plan, grid street plan, or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid. Two inherent characteristics of the grid plan, frequent intersections and orthogonal geometry, facilitate movement. The geometry helps with orientation and wayfinding and its frequent intersections with the choice and directness of route to desired destinations. In ancient Rome, the grid plan method of land measurement was called centuriation.
