INTRODUCTION within a city, a large share of the public right-of- way is devoted to transportation facilities. A facility may be a street, sidewalk, bikeway, or access way which is used by automobiles, trucks, transit vehicles, bicycles, or pedestrians. This document contains design standards for arterial, collector and local streets to ensure the safe and efficient operation of each facility type for all users and judicious use of the public space. The standards contained in this document apply to new construction, reconstruction, and improvements to existing unimproved streets, except as specified in this document. The standards apply to both public and private streets unless specified otherwise. Situations may arise where the design standards cannot be rigidly applied. Under special circum- stances, some flexibility of the standards will be necessary to create a design that is sensitive to the specific needs and features of the location. For example, reconstructions of existing streets may be difficult due to the limitations of existing right-of- way. There may be trees, buildings, or other fea- tures which result in the need for a narrower street cross-section. Street designs must consider the needs of people with disabilities, such as visually impaired pedestri- ans and pedestrians in wheelchairs. Every effort should be made to locate street hardware away from pedestrian locations and provide a surface free of bumps and cracks which create safety and mobility problems. Smooth access ramps shall be provided where required... The determination of the pavement width and total right-of-way shall be based on the operational needs for each street as determined by a technical analysis. The technical analysis shall use forecasted demand volumes that reflect the maximum number of pedestrians, bicyclists, parked vehicles and traffic expected when the area using the street is fully developed. As the analysis identifies specific needs such as bike lanes, parking or turn lanes, the width of the street can be established. Figure 1 illustrates elements which are typically incorporated in the transportation right-of--way such as sidewalks, planting strips, parking spaces, on- street bicycle lanes, and vehicle travel space, which may include left-turn lanes and/or median islands The width, size, and/or design of the elements frequently differ depending on whether the roadway is classified as a local, neighborhood collector, major collector, minor arterial, or major arterial street. In the functional hierarchy of streets, collec- torand arterial streets are considered to be major streets. Local street types are considered to be minor streets and are further divided into sub- classifications depending on the function and location of the street.
