2. The cul-de-sac style consists of disconnected roads, many ending in cul-de-sacs, making direct trips impossible even within neighborhoods.

1. Mixed-use.

Mixed-use zoning allows a mix of uses, such as commercial and residential, to occur in the same area. For example, apartments could be provided over retail shops, or a small neighborhood store within walking distance of all residences. Neighborhood schools are often a part of this mix. Home-based businesses are encouraged, and small-scale offices of the traditional design are permitted to provide local jobs that are within walking distance.

Single-use zoning is the predominant development pattern seen in America, and is a major contributor to traffic congestion. Single-use zoning requires the separation of all land uses from each other, such as residential, retail, recreational, commercial, and industrial. It also often results in land uses being physically separated from each other by fences and other barriers to physically prevent access between each type of land use, even by walking and bicycling. As a consequence, all trips must be made by car. Often even circulation within the neighborhood must be made by car and access by emergency service vehicles is also seriously curtailed.

A rural road typically has a limited number of elements: asphalt for the required number of lanes, and ditches for drainage. Pedestrians and bicyclists are excluded, unless there is a shoulder. Trees are often cleared in a wide swath from the edges of the road to create an open, clear space as a safety feature for drivers who leave the road, however this may also increase travel speeds.

Rural roads are the most dangerous style of road that we can construct because of the high speeds and lack of facilities for pedestrians and bicyclists. These are typically difficult and dangerous roads for pedestrians, bicyclists, and vehicles to cross.
