摘要：	This report presents the findings of a research project that investigated lighting design for nighttime highway construction operations. The objectives of the project were (1) to survey work zone lighting practices used in Illinois and other states, (2) to evaluate and recommend design criteria for lighting nighttime construction operations, and (3) to evaluate the performance of selected lighting arrangements for typical construction operations. To achieve these objectives, the research tasks were organized in five major phases: (1) literature review; (2) surveys; (3) evaluation and recommendation of lighting design criteria; (4) field studies; and (5) recommendations for lighting arrangements. In the first phase of the project, a thorough literature review was conducted to establish baseline knowledge of the latest research and developments in lighting nighttime construction operations. Surveys were conducted in the second phase to investigate current nighttime lighting practices and needs in Illinois and other states. In the third phase, lighting design criteria were evaluated and recommended for nighttime construction operations. The design criteria included requirements for illuminance, uniformity, glare, and light trespass during nighttime construction, and are summarized in a sample lighting specification. Field experiments were conducted in the fourth phase to examine the performance of selected lighting arrangements. In these experiments, a number of practical lighting arrangements were found to satisfy the requirements of the recommended lighting design criteria. The fifth and final phase of the project provides practical recommendations to help nighttime construction personnel in complying with the requirements of the recommended lighting design criteria.
