Using Smart Work Zone Trailer Data to Evaluate and Predict Lane Closure Impacts With a Consideration of Work Intensity
This report describes the implementation of machine learning (ML) models to the prediction of work zone traffic impacts including local speed and traffic volume changes and corridor-level travel time … [Read more...] about Using Smart Work Zone Trailer Data to Evaluate and Predict Lane Closure Impacts With a Consideration of Work Intensity
Estimation of Traffic Demand at Freeway Work Zones
An iterative process, combining a macroscopic simulator and a set of the traffic demand-change estimation models, is developed to estimate the traffic demand at work zones in urban freeway corridors. … [Read more...] about Estimation of Traffic Demand at Freeway Work Zones
A Deep Machine Learning Approach for Predicting Freeway Work Zone Delay Using Big Data
The introduction of deep learning and big data analytics may significantly elevate the performance of traffic speed prediction. Work zones become one of the most critical factors causing congestion … [Read more...] about A Deep Machine Learning Approach for Predicting Freeway Work Zone Delay Using Big Data
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
Agile Work Zone Management Based on Probe Traffic Data
Peak period lane closures can result in significant queueing on major interstates. As a result, many state agencies have a lane closure policy in place based upon historical time of day and day of … [Read more...] about Agile Work Zone Management Based on Probe Traffic Data
