    "abstract": "A primary purpose of this review is to identify and summarize recently\npublished information about the use and performance of light-emitting diode\n(LED) traffic signals. It consists of two sections: a synopsis of experiences\nof municipalities using LED traffic signals in 1999 and 2000, and a discussion\nof technical, economic and market issues surrounding the deployment of LED\nsignals. This review includes articles and reports published in 1999 and 2000.",
