Even though it seems these uses conflict with one another, the physical design is such that drivers are placed in an inferior position. Pedestrians, children at play, bicyclists, parked cars, and moving cars all share the same street space. The underlying concept of the shared street system is one of integration, with an emphasis on the community and the residential user. The commonly held perception that onвЂђstreet parking will create situations where children dart from behind a parked car into passing traffic is not borne out by actual experience. OnвЂђstreet parking also provides an important physical and psychological buffer between pedestrians on the sidewalk and traffic. OnвЂђstreet parking should be especially encouraged near the center of the neighborhood planning area, closest to the neighborhood focal point, services, transit stops, and so on. OnвЂђstreet parking should be encouraged whenever possible, as it is a highly efficient form of parking, especially where higher housing densities and a compact neighborhood are desired. They can range from on-street parking and shared streets, to more nuts-and-bolts features like sufficient vehicle turning radii and fire vehicle access. DESIGN CONCEPTS AND GUIDELINES FOR RESIDENTIAL SUBDIVISION PLANNINGДЄ number of different design concepts may be implemented to help preserve the residential feel when applying street design guidelines for healthy neighborhoods. Through careful design, this can produce cost savings in grading, drainage, and street construction, and lessen the amount of impervious surfaces. For example, the width of residential streets may be as narrow as 20 ft. A singleвЂђlane configuration is sufficient if parking lanes are incorporated or passing places are provided. Related streetscaping (street furniture, lighting, landscaping, etc.)ДЇor streets of up to 750 vehicles per day, traffic and delay considerations do not necessitate the need for more than one traffic lane.Lateral changes in the road (e.g., chicanes, narrowing, traffic diverters, etc.).Vertical changes to the road (e.g., speed bumps and humps, raised intersections, etc.).Traffic calming includes a variety of design techniques and traffic management programs: Traffic calming improves neighborhood livability and the pedestrian environment by reducing vehicle speeds and noise, visual impacts, and throughвЂђtraffic volumes. TRAFFIC CALMING IN RESIDENTIAL DEVELOPMENT Set the radius of culвЂђdeвЂђsacs to the minimum required to accommodate emergency and maintenance vehicles, while considering alternative turnarounds.Residential streets are regularly used as play areas, so design them to reflect a pedestrian orientation rather than only to facilitate vehicular movement.

In any residential street layout, provide a series of spaces in which the road pavement plays an integrated function, as opposed to the typical linear pavement that just facilitates automobile movement.

Minimize the amount of internal travel while maximizing convenience of access to nonresidential activities.

Consider the following four key design criteria for use within residential areas: When designing street layouts, especially suburban streets and neighborhoods, itвЂ™s important to avoid directing major traffic circulation through residential developments. RESIDENTIAL STREETS AND GUIDELINES FOR HEALTHY NEIGHBORHOODS When designing street layouts in residential developments, there are a number of important additional considerations, including safety. Nevertheless, be certain private roads are wide enough to allow passage of fire and emergency vehicles.

When private driveways and roadways will serve only passenger vehicles, it may be appropriate in some instances to use smaller dimensions. Residential streets and highways are designed to accommodate a variety of vehicles, up to and including semitrailer trucks.
