Urban and suburban arterials are signalized streets that primarily serve through traffic and provide access to properties as a secondary function. For purposes of this manual, they are defined as facilities with a signalized intersection spacing of 2 miles or less and turning movements at intersections that usually do not exceed 20 percent of total traffic volumes. Roadside development along arterials can be intense, producing frictions to traffic that generally limit a driver's desired speed. In the system of urban highway transportation facilities, arterial streets are between collector and downtown streets on one side and multilane suburban highways and rural roads on the other side. The difference is mainly determined by their function and the character and intensity of roadside development. The methodology of this chapter is oriented to the evaluation of an existing operations situation, or evaluating a specific design proposal, by a level of service determination. The person doing such design or operations work will be able to investigate the effect of signal spacing, arterial class (as defined herein), and traffic flow on the arterial level of service. The methodology makes use of the Signalized Intersection procedure of Chapter 9 for the lane group containing the through traffic. By re-defining lane arrangement (e.g. presence or absence of left turn lanes, number of lanes), the analyst may influence which traffic flow is in the "through traffic" lane group and the capacity of the lane group. This, in turn, influences the arterial LOS determination by changing the intersection evaluation and possibly the arterial classification. (Author)
