Overview
Arterial roadways are a significant portion of the highway network, especially in urban areas. There are many benefits to a Transportation Systems Management and Operations (TSMO) program focused on control strategies for signalized corridors to improve travel time and reliability; multimodal system efficiency; cost-effectiveness; and importantly, road safety. These outcomes benefit transportation agencies and the traveling public.
The AASHTO Transportation Operations Manual (TOM) includes Chapter 21: Arterial Management as the primary focus point on this topic. Other related information on arterial management are available in:
