The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement

Transportation agencies are increasingly using probe vehicle data for transportation system performance management and as a resource for meeting the federal requirements of monitoring and reporting … [Read more...] about The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement

The Role That Connected and Automated Vehicles Can Play in Re-Organizing Traffic Flow: Work Zones and Emergency Services

The extensive progresses in computer science and communication technology in recent decades facilitate the development of the connected and automated vehicles (CAV). Since the emergence of the … [Read more...] about The Role That Connected and Automated Vehicles Can Play in Re-Organizing Traffic Flow: Work Zones and Emergency Services

Fault-Tolerant Control of Variable Speed Limits for Freeway Work Zone Using Likelihood Estimation

Freeway work zone with lane closure can lead to disruption to local traffic and cause significant impacts on mobility, safety and environmental sustainability. To mitigate traffic congestion near work … [Read more...] about Fault-Tolerant Control of Variable Speed Limits for Freeway Work Zone Using Likelihood Estimation

Machine Learning Approach to Forecast Work Zone Mobility Using Probe Vehicle Data

The aim of deploying intelligent transportation systems (ITS) is often to help engineers and operators identify traffic congestion. The future of ITS-based traffic management is the prediction of … [Read more...] about Machine Learning Approach to Forecast Work Zone Mobility Using Probe Vehicle Data

Probabilistic Speed–Flow Models in Highway Construction Work Zones

Since variations in exogenous factors could cause unpredictable fluctuations/variability of the speed–flow relationship, the aim of this study was to develop probabilistic speed–flow relationships in … [Read more...] about Probabilistic Speed–Flow Models in Highway Construction Work Zones

A Comparison of Capacity Estimation Methods for Two-Way Four-Lane Freeway Work Zone Capacity Using Field Data

Work zone environments are complex, and adequate capacity estimation methods must consider more factors than regular freeway sections. In order to avoid the undue influences on the traffic capacity … [Read more...] about A Comparison of Capacity Estimation Methods for Two-Way Four-Lane Freeway Work Zone Capacity Using Field Data
