Study | Strategy | Period | Lane closure configuration | Approach of analysis | Findings |
[28] | Static Late merge vs early merge | Short-term | 2-to-1, 3-to-1, and 3-to-2 | Microscopic simulation | Late merge is better |
[12] | Static Late merge, early merge, signalized merge | Short-term | 2-to-1, 3-to-1, and 3-to-2 | Microscopic simulation | Late merge is better for high volumes, Early merge is better for low volume |
[13] , [14] | Conventional practice, Dynamic early and Dynamic late | Short-term | 2-to-1, 3-to-2 | Microscopic simulation | Dynamic early merge is better |
[29] | Zipper merge | Congested time period at field site | 2-to-1, 3-to-2 | Field test on Freeways, arterials | Increased safety, reduced travel time |
[30] | Dynamic Late merge | Field site | 2-to-1 | Microscopic simulation | Dynamic late merge is better than conventional |
[31] | Dynamic Late merge | Field site | 2-to-1 | Field test on Freeways | Reduced travel time; better than early merge |
