Percent of Signs that are in Fair to Excellent Condition

Measure Description
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. Having a reasonable estimate of the number of traffic signs in need of maintenance allows for the programming of future resource needs.
Calculation Method
This measure is the total number of traffic signs that are considered in fair to excellent condition divided by the total number of traffic signs.
FY 2014-15 Results
Approximately 89% of the signs were considered in “fair to excellent” condition. This result was slightly below the goal of 90%.
Assessment of Results
Based on the procedures used to estimate signs in fair to excellent condition, the Austin Transportation Department (ATD) has exceeded the goal for 4 of the past 5 years. Over the past few years, the Signs Division has reassigned staff from installing signs to assist with other business operations such as planning support, data management, performance metric reporting, and sign fabrication. Although not currently evident in this metric's performance, the reduction in sign installers is reducing the ability to adequately maintain signs. In FY 2014-15, almost 12,000 signs were installed or maintained, down from 17,000 signs maintained in FY 2011-12.

Next Steps
The Signs Division is under new leadership in FY 2015-16 and is investigating resources and procedures needed to deliver a quality and sustainable sign installation and maintenance program.
Initial efforts to use the City's Maximo 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 appears to offer: (1) integration with GIS (Geographic Information Systems/online mapping) to track sign field inventory; and (2) ability to monitor a sign's nighttime visibility in order to plan for sign replacement. Additionally, sign maintenance activities consider proper position, cleanliness, legibility, and daytime and nighttime visibility (retro-reflectivity). Any damaged or deteriorating signs need to be replaced. ATD is developing and implementing procedures that are leading to a proactive (planned) sign maintenance program. The goal for the current year FY 2015-16 is to finalize and implement these procedures.
