3.0 Pavement Network <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 <br />designed to accommodate between 30,000 and 50,600 vehicle trips daily. This facility <br />type comprises approximately 58 centerline miles or 55 percent of City arterial network. <br />• Primary Arterial — Generally consists of a four -lane, divided roadway serving as a major <br />access route to regional destinations (such as downtown and similar major focal points <br />within the City). A primary arterial is designed to accommodate between 20,000 and <br />30,000 vehicle trips daily. This facility type comprises approximately 10 centerline miles <br />or 9 percent of City arterial network. <br />• Secondary Arterial — Generally consists of a four -lane, undivided roadway serving <br />intra -city mobility. A secondary arterial is designed to accommodate between 10,000 <br />and 20,000 vehicle trips daily. This facility type comprises approximately 35 centerline <br />miles or 33percent of City arterial network. <br />• Collector Street — Generally consists of a two-lane, undivided roadway. A collector <br />street is designed to accommodate between 7,500 and 10,000 vehicle trips daily. This <br />facility type comprises approximately 3 centerline miles or 3 percent of City arterial <br />network. <br />Figure 3-2: Arterial Street <br />City of Santa Ana 2018 Pavement Management Program J-` <br />55B-19 <br />
