abstract="Transitions between regimes in the speed-flow relationship were the topic of a recent paper by the authors (Transportation Research Record 1005, 1985). Subsequently, the authors have found that a different analytic technique provides better insights into this problem. This approach involves the use of daily time-traced and overlaid time-traced plots. The result of the re-analysis is that four previous conclusions are confirmed and one is not. Several questions that remained after the first paper about the shape of the relationship and its transitions are resolved, although why operation in shoulder lanes is different from that in the nonshoulder lanes is still unclear.<p /><p>Language: en</p>",
