National Highways Looks Forward With ‘Bold’ New Approach to Roadworks
National Highways is developing a series of measures to reduce the impact of vital work being carried out on the Strategic Road Network. This includes an increase in the use of higher speed limits … [Read more...] about National Highways Looks Forward With ‘Bold’ New Approach to Roadworks
Applying Clustered KNN Algorithm for Short-Term Travel Speed Prediction and Reduced Speed Detection on Urban Arterial Road Work Zones
This study developed and verified a travel speed prediction model based on the travel speed and work zone statistics collected from the advanced traffic management system (ATMS) real-time data in … [Read more...] about Applying Clustered KNN Algorithm for Short-Term Travel Speed Prediction and Reduced Speed Detection on Urban Arterial Road Work Zones
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
