Advancing Practices for Localized Traffic Analysis and Work Zone Management During Voting Events
The Federal Highway Administration (FHWA) supports the use of traffic analysis tools and enhanced work zone management to improve access to voting events. One aspect of voting access is the … [Read more...] about Advancing Practices for Localized Traffic Analysis and Work Zone Management During Voting Events
Simulation of Roadside LiDAR Applications: A Smart Work Zone Case Study
Light detection and ranging (LiDAR) have the capability to detect 360-degree surrounding objects with high accuracy (centimeter level), high frequency (a tenth of a second), and long measuring … [Read more...] about Simulation of Roadside LiDAR Applications: A Smart Work Zone Case Study
Safety and Mobility Analysis of Rolling Slowdown for Work Zones: Comparison with Full Closure
There are times when the traffic lanes through a work zone must be kept clear for activities such as placing overhead beams, erecting overhead signs, and installing power lines, and other temporary … [Read more...] about Safety and Mobility Analysis of Rolling Slowdown for Work Zones: Comparison with Full Closure
Method for Estimating Capacity and Measures of Effectiveness of Two-Lane Highway Work Zones
The present study proposes a method for determining the capacity and measures of effectiveness of two-lane highway work zones. Therefore, a deterministic mathematical formulation was developed based … [Read more...] about Method for Estimating Capacity and Measures of Effectiveness of Two-Lane Highway Work Zones
Calibration and Validation of a Microsimulation Model of Lane Closures on a Two-Lane Highway Work Zone
Lane closure on a two-lane work zone can negatively affect operational performance. Although a microsimulation model is often used to quantify and predict these negative impacts, it requires proper … [Read more...] about Calibration and Validation of a Microsimulation Model of Lane Closures on a Two-Lane Highway Work Zone
