  1. Traffic Management Signing Target: 8% of all signs replaced annually (to meet 12-year replacement cycle) CY2003 Performance: 6.5% • Data is insufficient to identify percent of signs in system that are greater than 12 years old or deficient in retroreflectivity. • Does not include signs replaced due to knockdowns or vandalism. 2003 Highway Signing Replacement - % of Plans Completed Combined Totals Note: Current replacement schedule is as follows: VIP sheeting 15 year replacement High Intensity sheeting 12 year replacement Comments – District Sign Experts D1 replaced more signs, 2,453 on contract, to catch up from low replacement the previous year. D3 replaced defective signs based on inspection, for highways scheduled. D4 is piloting just-in-time replacement, hence didn’t have roads programmed. I94 had a contract. D6 output was low due to staffing cuts and more signs hit by traffic. Hope to improve in 2004. D7 has signs purchased in 2002 remaining, which it will install when funds available in 2005. D8 exceeded plan due in part to replacement of cylindrical delineators, most below stop signs. • Comments – District Operations Meeting, May 3, 2004 • 6.5 percent of signs were replaced in 2003, falling short of the dashboard target to replace 8% annually to achieve a 12-year replacement cycle. This measure does not capture backlog needs of some districts. • The table shows the measure used in 2002 - the percent of each district’s signing plan completed. It was useful at the operational level, but didn’t meet the department need for a system condition measure. • Several districts and the Division Director urged development of a uniform inventory system, and an outcome-based measure that tells what percent of signs meet reflectivity targets. This is the 3rd year of collecting all sign replacement (district and contract) data. We lack a good inventory software system and resources. We need to know more on how long signs last. Several districts are doing pilots, including night surveys of reflectivity. • Action • The Maintenance Business Management Team will improve system of measures and data collection.
