This paper considers the problem of estimating road user costs (RUCs), such as travel time and delays, for roadway construction projects under time and data limitations. RUCs measure the mobility … [Read more...] about Estimation of Road User Costs for Work Zones in Data-Limited or Time-Constrained Environments

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
Modeling the Effect of a Freeway Road Construction Project on Link-Level Travel Times
Drivers experience variations in travel time due to congestion and delays associated with road construction projects on existing transportation facilities. The effect on the travel time of a link … [Read more...] about Modeling the Effect of a Freeway Road Construction Project on Link-Level Travel Times
Utilizing Probe-Vehicle Data for Work Zone Mobility Performance Management
The Virginia Department of Transportation (VDOT) uses probe vehicle data from different sources to measure highway system mobility performance at both the macro- and microlevels. VDOT uses delay as … [Read more...] about Utilizing Probe-Vehicle Data for Work Zone Mobility Performance Management
Live Cams, Speed Sensors Track Traffic in Merritt Parkway Work Zone
For years, the $56.7 million project on a 5-mile stretch of the Merritt Parkway in Fairfield and Westport has caused lane closures and traffic delays. As the project enters its next phase, commuters … [Read more...] about Live Cams, Speed Sensors Track Traffic in Merritt Parkway Work Zone
Optimizing Work-Zone Schedule with Floating Car Data Considering Traffic Diversion and Managed Lanes
Work zones have become the second largest contributor to the nonrecurring delay disruptions of traffic on US highways. The development of a sound model to minimize the total cost (i.e., road user cost … [Read more...] about Optimizing Work-Zone Schedule with Floating Car Data Considering Traffic Diversion and Managed Lanes
