Investigation of Alternative Work Zone Merging Sign Configurations
This study investigated the effect of an alternative merge sign configuration within a freeway work zone. In this alternative configuration, the graphical lane closed sign from the Manual on Uniform … [Read more...] about Investigation of Alternative Work Zone Merging Sign Configurations
‘Zipper Merge’ Proposed for Saskatoon Work Zones
Saskatoon is introducing zipper merging, a new method of traffic control, to mitigate traffic congestion in its work zones. Zipper merging requires motorists to use two lanes as they near a merging … [Read more...] about ‘Zipper Merge’ Proposed for Saskatoon Work Zones
Classification and Regression Tree Approach for Predicting Drivers’ Merging Behavior in Short-Term Work Zone Merging Areas
This study aims to use the classification and regression tree (CART) approach, one of the most powerful data mining techniques, to predict drivers’ merging behavior in a work zone merging area. On the … [Read more...] about Classification and Regression Tree Approach for Predicting Drivers’ Merging Behavior in Short-Term Work Zone Merging Areas
Rear-End Crash Potential Estimation in the Work Zone Merging Areas
This paper proposed a methodology to estimate rear-end crash potential of the merging vehicles traveling in the merge lane, on the basis of the traffic data extracting from the available videotapes. … [Read more...] about Rear-End Crash Potential Estimation in the Work Zone Merging Areas
Modeling Speed-Flow Relationship and Merging Behavior in Work Zone Merging Areas
This paper aims to investigate the speed-flow relationship and drivers' merging behavior in work zone merging areas. It first proposes lane-based speed-flow models, incorporating traffic conflicts … [Read more...] about Modeling Speed-Flow Relationship and Merging Behavior in Work Zone Merging Areas
