Passive RFID-Based Inventory of Traffic Signs on Roads and Urban Environments

Abstract

This paper presents a system with location functionalities for the inventory of traffic signs based on passive RFID technology. The proposed system simplifies the current video-based techniques, whose requirements regarding visibility are difficult to meet in some scenarios, such as dense urban areas. In addition, the system can be easily extended to consider any other street facilities, such as dumpsters or traffic lights. Furthermore, the system can perform the inventory process at night and at a vehicle’s usual speed, thus avoiding interfering with the normal traffic flow of the road. Moreover, the proposed system exploits the benefits of the passive RFID technologies over active RFID, which are typically employed on inventory and vehicular routing applications. Since the performance of passive RFID is not obvious for the required distance ranges on these in-motion scenarios, this paper, as its main contribution, addresses the problem in two different ways, on the one hand theoretically, presenting a radio wave propagation model at theoretical and simulation level for these scenarios; and on the other hand experimentally, comparing passive and active RFID alternatives regarding costs, power consumption, distance ranges, collision problems, and ease of reconfiguration. Finally, the performance of the proposed on-board system is experimentally validated, testing its capabilities for inventory purposes.

RF-Enhanced Pavement Markings for Mobile Robot Lane Detection

“…Therefore, RFID, as a passive detection method, perfectly addresses this issue. For example, RFID tags are installed on traffic signs such that any vehicle with RFID readers can interrogate sign status and update the cloud server as the vehicle moves [6,13,16].…”

“…We propose a more efficient and extensible approach for traffic sign detection for inventory management-encoding traffic rules within RFID tags. These tags can then be interrogated by passing vehicles, which can transmit related information to a cloud server for real-time inventory updates [13,6].…”

Traffic Intersection Lane Control Using Radio Frequency Identification and 5G Communication

“…Due to the limitations of video technology, we propose here a new concept using the Radio Frequency IDentification known as RFID [68,69]. It seems relatively easy to use and inexpensive, and the data collected from RFID transponders does not have to be subjected to demanding image recognition algorithms [70,71]. The use of RFID makes it possible to obtain accurate information not only about how many vehicles are driving in a given lane, but also which vehicle we are dealing with [72].…”
