The document discusses the application of license plate recognition (LPR) technique in transportation management. It outlines how LPR can be used for traffic management by collecting traffic data through image recognition systems. This data can then be analyzed to help with traffic control, payments, and monitoring for things like accidents or traffic violations. The document also describes the typical components of an LPR system, including cameras, computers, data transmission methods, and surveillance systems to analyze captured license plate images in real-time. In summary, LPR is presented as a tool that can help optimize traffic flow and efficiency through automated license plate data collection and monitoring on roads, highways and in parking applications.
