Costs for RFID tags by quantity and durability are provided in table A-1.
The RFID industry has multiple standards and an established class system. The industry also subdivides standards according to interface protocol, data content, conformance, and applications.(1) The Electronic Product Code (EPC) standard specifies longevity and memory requirements Memory requirements include:

The objective of this report was to identify available ID methods to improve the data collected on roadside safety hardware to use for ISPEs and evaluate those methods. The study found that there are mainly three types of ID methods that are feasible and available for use. Each ID method has advantages and disadvantages when considering their ability to convey information, withstand roadside conditions, and connect to existing agency asset management systems or other databases.
Based on the identified ID methods discussed, an evaluation matrix was created to compare the performance of each in various areas. A grading system was used to create the evaluation matrix. Grades were based primarily on a review of literature, and a review of manufacturer specifications. Participation in various demonstrations, and input from the expert panel through consensus also informed the grading.
After understanding the different ID methods, transportation agencies may consider several issues when selecting the appropriate ID methods for their network. This report identifies six primary performance issues regarding deployment of the ID methods identified:
This chapter provides an overview of the specific tag identifier technologies, and their relative performance, used by transportation agencies to tag roadside safety hardware. This review focuses on the following three primary tag identifiers as ID methods:
At the time of this report, we found no transportation agencies having full-scale ISPE programs in place, although several pilot programs are underway. However, some transportation agencies do track specific roadway safety hardware or use asset management systems for roadway inventories that include roadside safety hardware. A few transportation agencies have also experimented with the investigated ID methods for a variety of purposes.
Section 1429 of the FAST Act requires the Secretary of Transportation to study ID methods that transportation agencies can use to collect data about their roadside highway safety hardware. Transportation agencies can use these ID methods to evaluate the in-service performance of the roadside safety hardware and improve the data collected about the hardware. Section 1429 states the following:
