| 摘要： | The overall objective of the research documented in this report was to find better ways to control traffic at work zones on rural interstate highways. The primary focus was on improving the safety and efficiency of the merging operations in advance of lane closures. The research involved the identification and evaluation of alternative strategies designed to control traffic speeds and merging operations in advance of lane closures. Twelve alternatives were identified as a result of a literature review, brainstorming session, and survey of states. The alternatives and the existing merge control strategy used by the Nebraska Department of Roads, NDOR Merge, were evaluated using computer simulation. In addition, field evaluations of the NDOR Merge and two alternatives, the Indiana Lane Merge and Late Merge, were also conducted. Field studies of the Indiana Lane Merge and the Late Merge were conducted at work zones in Indiana and Pennsylvania, respectively. Field studies of the NDOR Merge were conducted at work zones on I-80 in Nebraska. The field data were used to determine the safety and operational effects of these merge control strategies. |
