This report presents the results of research to investigate the feasibility and effectiveness of the late-merge lane closure strategy and the CB Wizard technology at work zones in Texas. Previous research findings indicate that the late-merge strategy does offer the potential to improve vehicle throughput, queue lengths, and delays at work zone lane closures. Simulation analyses performed in this project suggest that the strategy may also be useful in managing queues at other types of major merge areas upstream or within work zones by modifying the relative service rates allocated to each approach or lane. Studies of the CB Wizard Technology suggest that it can influence both the speed and lane choices of truck operators approaching work zones, but the extent of this influence is heavily dependent upon roadway and work zone site characteristics. The report also provides implementation guidelines for incorporating enforcement pullout areas into long work zones where emergency shoulders have been eliminated.
