Percent of Signs That are in Fair to Excellent Condition
Traffic signs must be legible to the traveling public in order to promote safe and efficient mobility. This measure estimates the overall condition of traffic signs maintained by the City. Traffic signs have a finite life, generally 8-10 years, unless subjected to damage, graffiti, or extreme exposure to the elements. By having a reasonable estimate of the number of traffic signs in need of maintenance, the Austin Transportation Department (ATD) is better able to allocate future resources to the program.
This measure is calculated by identifying the number of traffic signs that are considered in fair to excellent condition divided by the total number of traffic signs.
FY 2015-16 Results
In FY 2015-16, 86% of the signs were considered in ‘fair to excellent’ condition, 4% below the established goal of 90%.
Assessment of Results
Based on the procedures used to estimate signs in fair to excellent condition, ATD was just short of meeting the goal. Over the past few years, the Signs Division reassigned staff from installing signs in order to assist with other business operations, such as planning support, data management, performance metric reporting, and sign fabrication. The reduction in sign installers reduced the overall ability to adequately maintain signs. In FY 2015-16, the Signs Division had new leadership who evaluated resources and began implementing procedures needed to deliver a quality and sustainable sign installation and maintenance program.
Initial efforts to use the City's Maximo inventory database to track sign installations and maintenance have produced efficiencies compared to solely relying on paper work tickets. Today, information can easily be queried regarding productivity and performance metrics. Additional efforts are underway to leverage other efficiencies that Maximo may offer, such as integration with Geographic Information Systems (GIS) to track sign field inventory and the ability to monitor sign age and retroreflectivity in order to plan for sign replacement.
ATD developed and is currently in the process of implementing procedures for a proactive (planned) sign maintenance program. The sign maintenance program will improve the overall condition of the installed traffic control signs and insure minimum levels of retroreflectivity. In FY 2016-17, ATD anticipates implementing these procedures.
