AVI programs becoming more aggressive with passive UHF technology
Tuesday, 03 May 2016 09:00

The U.S. Department of Transportation’s MAP-21 program could be a treasure map of opportunity for RFID developers with creativity and patience. MAP-21 is an acronym for Moving Ahead for Progress in the 21st Century Act, a piece of legislation that earmarked more than $100 billion to modernize the U.S. highway system.

MAP-21 includes efforts to improve and possibly standardize toll tagging systems. Most vehicle toll tags used for turnpikes and other public highway systems today use active RFID technology, but many vehicle ID tags used for parking control and other private access are passive UHF tags. There are multiple standards, which hasn’t really standardized the environment at all, resulting in many vehicles using multiple tags.

Now there is growing interest in passive UHF RFID technology for highway tolling and other over-the-road use cases. Intelligent highway system planners are intrigued by the higher security now available in ISO-18000-6C/EPCglobal Gen 2-standard passive UHF, along with the technology’s comparatively low cost. Performance is also a big factor in the growing enthusiasm for using passive RFID for automatic vehicle identification (AVI). Active technology has traditionally been favored because of its long read range, but passive UHF can also provide the required range and reliability. We know this firsthand, because AWID is a long-time provider of passive AVI technology and we have many customers using our long-range readers and tags for access control, automated parking management, vehicle registration, asset tracking and related applications.

If you have a fleet of vehicles, need to coordinate vehicle access, yard management or parking control operations, or develop solutions for those business processes, take the time to follow MAP-21 developments and considered how low-cost, reliable long-range passive RFID might add value.
