The Effects of Late Lane Merges on Travel Times

The objectives of this proposed research are to provide the North Carolina Department of Transportation (NCDOT) with objective, scientific guidance on the effects of drivers making late lane merge maneuvers. The research team will conduct the project in two basic phases, including office and field work. In the office, the team will collect and analyze cost, delay, and collision report data from existing locations with some configuration of treatment methods. If this data is available historically, it will also be collected and analyzed. Another portion of the office work could consist of modeling various roadway lane configurations in simulation software in order to analyze the ideal lane change point with regards to traffic delay and capacity, if these measurements cannot be accurately made in the field. In the field, the team will gather data on driver reactions to current treatments using video equipment, with the potential for comparison of the various devices depending on the respective times and locations of implementation. Wherever possible, the team will perform a before-after comparison of driver reactions, as well as travel times, with respect to frequency of the late lane merging behavior.
