Delay or Travel Time Information? The Impact of Advanced Traveler Information Systems on Drivers’ Behavior Before Freeway Work Zones
Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and travel times en-route and … [Read more...] about Delay or Travel Time Information? The Impact of Advanced Traveler Information Systems on Drivers’ Behavior Before Freeway Work Zones
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
How Does the Value of Time Influence Road User Costs During Work Zone Closures? A Case Study in El Paso, Texas, Using Simulation-Based Modeling Methods
It is becoming standard practice for many departments of transportation (DOTs) to use incentive/disincentive clauses (also known as road user costs) with contractors to stay on or ahead of schedule. … [Read more...] about How Does the Value of Time Influence Road User Costs During Work Zone Closures? A Case Study in El Paso, Texas, Using Simulation-Based Modeling Methods
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
