Pavement Condition Index
Pavement Condition Index
The Pavement Condition Index (PCI) is the measure of the current pavement condition of each street segment, typically one block in length. The PCI is determined by inspecting each street every three years and calculating a numerical rating of 1 to 100 for each street section. The city uses the following rating ranges to categorize the relative condition of the street: 90 to 100 is excellent; 80 to 89 is very good; 70 to 79 is good; 55 to 69 is fair; and less than 55 is poor. The city’s goal of a 75 to 80 PCI is consistent with other communities in the Denver metro area. The PCI rating is not an indication that streets are in a dangerous condition. The network PCI is determined by calculating a weighted average of the conditions, accounting for the varying pavement area of each segment. Geo-referenced digital imagery is collected by a vehicle driving each street with a forward and back facing camera. The imagery is then evaluated in an office environment to determine the extent of various surface distress categories and their severity per the standards developed by the U.S Army Corps of Engineers. The calculations are performed by software based on the surface distresses found.
Achieve a network PCI of 75 to 80.
The Transportation Division has established a Pavement Management Program (PMP) for Boulder’s 300-mile street system which is approximately 630 lane miles. Lane miles is the total length of travel pavement multiplied by the number of lanes. The PMP includes inspecting and rating all streets on a three-year interval to maintain awareness of existing conditions and guide future pavement repairs. The goal of the PMP is to identify the optimal level of funding, timing and renewal strategies that will keep the roadway network at the targeted average PCI rating of 75 to 80. Additional transportation funding provided by two voter initiatives -- a 2011 bond and a 2013 sales tax – have supported progress toward meeting the city’s PMP objective. However, the PMP is still in the early stages of implementation and much work remains to be completed. Updated results of the PMP are included in the Transportation Report on Progress.
The city's street network is the primary infrastructure for all modes of travel. Recognizing this, the city's Transportation Master Plan places system operations and maintenance of the existing street network as the Highest funding priority. The Pavement Management Program utilizes the PCI to determine priority of funding and guide where future pavement repairs will be made to achieve this priority.
Since 2011, the city’s average PCI has been relatively flat with an average PCI rating of 76.5 in 2011 to an average PCI rating of 75.0 in 2018, both of which are equivalent to a good rating. Currently, over 66 percent of the streets are rated good, very good or excellent.
