Identification and Characterization of Mobile Work Zones Using Floating Car Data
This paper describes a methodology for the identifying active mobile roadworks zones based on detecting the forward forming shockwave associated with the congestion front with the use of vehicle probe … [Read more...] about Identification and Characterization of Mobile Work Zones Using Floating Car Data
Estimation of Road User Costs for Work Zones in Data-Limited or Time-Constrained Environments
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
