Issues With Work Zone Free Flow Speed Computation in 6th Edition HCM and Proposed Improvements
Free flow speed (FFS) and capacity of work zones (WZ) directly affect queue length and delay in the WZ. The 6th Edition of Highway Capacity Manual introduced a new model to estimate WZ FFS and … [Read more...] about Issues With Work Zone Free Flow Speed Computation in 6th Edition HCM and Proposed Improvements
Synthesis Study of Best Practices for Mapping and Coordinating Detours for Maintenance of Traffic (MOT) and Risk Assessment for Duration of Traffic Control Activities
Maintenance of traffic (MOT) during construction periods is critical to the success of project delivery and the overall mission of transportation agencies. MOT plans may include full road closures and … [Read more...] about Synthesis Study of Best Practices for Mapping and Coordinating Detours for Maintenance of Traffic (MOT) and Risk Assessment for Duration of Traffic Control Activities
Safety, Mobility, and Cost Benefits of Closing One Direction of the Interstate in Rural Areas During Construction Work
With specific regard to interstates in the rural area, Indiana Department of Transportation (INDOT) has expressed a need for research that sheds light on this Maintenance of Traffic (MOT) issue so the … [Read more...] about Safety, Mobility, and Cost Benefits of Closing One Direction of the Interstate in Rural Areas During Construction Work
Safety Impact of Connected Vehicles on Driver Behavior in Rural Work Zones Under Foggy Weather Conditions
Work zone (WZ) safety is one of the paramount goals of the safety community. Safety in WZs is a particular concern under foggy conditions as they represent an exogenous factor contributing to high … [Read more...] about Safety Impact of Connected Vehicles on Driver Behavior in Rural Work Zones Under Foggy Weather Conditions
