| 摘要： | The Storm Warning Project was initiated in 1993 as a result of a large number of serious traffic crashes that occurred during periods of low visibility on I-84 in southeastern Idaho between 1988 and 1993. The purpose of the project was to determine if visibility sensors and the resultant information supplied to drivers on roadway message signs would reduce vehicle speeds to safe levels as warranted by weather conditions. The report is organized to provide information in a sequence that corresponds to the chronology of the project. Section 1 introduces the project, and provides an overview of its history, a description of the systems tested, test objectives, and evaluation approach. Section 2 reports on the performance and reliability of the sensors. It documents Phase I of the project, which involved evaluating the sensors' ability to determine low visibility conditions. Section 3 discusses the response of drivers to the driving conditions and to the information provided by variable message signs. It documents Phase II of the project, which studied the degree to which driver behavior could be modified through presentation of roadway condition information via variable message signs. Section 4 presents the results and conclusions of this operational test. |
