Development of Recommendations for Arterial Lane Closures to Optimize Traffic Operations, Summary Report.

摘要

Researchers developed signal control optimization guidelines for three different situations. In the first, the work zone blocks one or more lanes upstream of the intersection, at some distance from the stop bar. In the second, the lane closure occurs at the stop bar. This situation was broken down into two subcases, one in which the lane closure changes the use of adjacent lanes, for example, a through lane becomes a turn/through lane, and another in which the lane closure reduces the number of lanes, but does not change open lanes functions. In the third situation, the lane closure is some distance downstream from the intersection of interest. In this case, the work zone area will block some lanes in the middle of an arterial link between two intersections. Detailed guidelines were developed to optimize signal control around each of the three work zone situations.
