Considerations in Developing a Strategic Arterial Street System
Recently, attention has been directed towards the urban arterial street system to provide greater mobility, specifically in the form of a network of high-mobility arterial streets. These streets were named stra tegic arterials and would operate with greater capacity and operating speeds than current principal arterials, however, they would not fulfill the strict requirements of a freeway in terms of access control or right-of-way needs. Planning analyses demonstrated that capacity of the streets was the primary factor in causing diversion from a freeway system to strategic arterial system. Design features associated with a strategic arterial should be different from ordinary arterial streets and identifiable by the motorist as being different. Several design criteria were identified. At-grade only improvements for a case study on an existing arterial resulted in limited increases in speed due to the highly congested nature of the area. Grade-separated improvements were needed to generate a speed that is near freeway speeds. A benefit/cost analysis of improving a 4-lane, urban city street to either a 6-lane, urban city street or a 6-lane strategic arterial demonstrated that the higher quality facility, even though more expensive, is a better investment. Implementation of strategic arterials will require strong local jurisdictional support, which will play a major role in the successful implementation of a strategic arterial network.
