Work zones that include a single lane closure on a two-lane, two-way roadway present unique traffic control challenges. In these situations, traffic regulators (i.e., flaggers or temporary traffic … [Read more...] about Effective Signing Strategies and Signal Displays for Work Zone Driveway Assistance Devices
Lane Closure
Agile Work Zone Management Based on Connected Vehicle Data
Peak period lane closures can result in significant queueing on major interstates. Many state agencies thus have a lane closure policy in place based upon historical time of day and day of week … [Read more...] about Agile Work Zone Management Based on Connected Vehicle Data
Improving Work Zone Mobility Through Planning, Design, and Operations
This research project consists of a series of tasks intended to yield results that will better inform transportation agencies in their planning, design, and operations of freeway work zones. This … [Read more...] about Improving Work Zone Mobility Through Planning, Design, and Operations
Enhancing Work Zone Capacity by a Cooperative Late Merge System Using Decentralized and Centralized Control Strategies
This paper explores the efficiency of a novel merging system based on a cooperative late merge strategy (CLMS) to mitigate the capacity reduction in work zones due to lane closure. Cooperative late … [Read more...] about Enhancing Work Zone Capacity by a Cooperative Late Merge System Using Decentralized and Centralized Control Strategies
