3.0 Pavement Network <br />City of Santa Ana 2024 Pavement Management Program 3-3-2 <br />3.1 FUNCTIONAL CLASSIFICATIONS <br />One of the critical factors affecting the roadbeds and pavement deterioration rate is the quantity <br />and associated vehicle weight of traffic utilizing the streets. The volume and type of vehicular <br />usage for the abovementioned arterial network’s four functional classifications are: <br />• Major Arterial – Generally consists of a six-travel lane, divided roadway connecting <br />various parts within the City of Santa Ana and adjacent cities. A major arterial is designed <br />to accommodate between 30,000 and 50,600 vehicle trips daily.

A primary arterial is designed to accommodate between 20,000 and <br />30,000 vehicle trips daily. This facility type comprises approximately 9 centerline miles or <br />8.6 percent of City arterial network. <br />• Secondary Arterial – Generally consists of a four-lane, undivided roadway serving intra- <br />city mobility. A secondary arterial is designed to accommodate between 10,000 and <br />20,000 vehicle trips daily. This facility type comprises approximately 35 centerline miles <br />or 33.3 percent of City arterial network. <br />• Collector Street – Generally consists of a two-lane, undivided roadway.
