Optimal Work Zone Lengths for Two-Lane Highways
Highway pavement maintenance is very expensive not only in terms of costs to the responsible agencies, but also in terms of disruptive delays to users. Construction and maintenance activities on … [Read more...] about Optimal Work Zone Lengths for Two-Lane Highways
Safety Models for Rural Freeway Work Zones
This research is a part of a project aimed at studying the performance and efficacy of the Indiana Lane Merge System (ILMS) in work zone locations. The crash prediction models presented here are … [Read more...] about Safety Models for Rural Freeway Work Zones
Optimal Work Zone Lengths for Four-Lane Highways
Highway pavement maintenance is very expensive not only in terms of costs to the responsible agencies but also in terms of disruptive delays to users. Construction and maintenance activities on … [Read more...] about Optimal Work Zone Lengths for Four-Lane Highways
Delay Estimation and Optimal Length for Four-Lane Divided Freeway Workzones
Vehicle delay is one of the most serious impacts of highway workzones on existing traffic operations. The present study provides a comprehensive and detailed estimation of traffic delay due to a … [Read more...] about Delay Estimation and Optimal Length for Four-Lane Divided Freeway Workzones
A Computational Vision Model-based Method to Address Work Zone Conspicuity
A computational means to assess the conspicuity of highway features was developed, verified, then applied to a sample construction work zone scene. This work was conceived as a balance between … [Read more...] about A Computational Vision Model-based Method to Address Work Zone Conspicuity
