The lane-changing probability for each DLC scenario was modeled as a function of corresponding important factors (obtained from focus group) and driver types. In gap acceptance modeling, the "hand-shaking negotiation" concept (from the TCP/IP protocols in computer network communications) was introduced to describe the vehicle interactions during lane-changing maneuvers under congested traffic flow. The proposed lane-changing model was developed and implemented in a microscopic traffic simulator, CORSIM. Traffic data were collected along a congested arterial in the City of Gainesville, FL, and used for model calibration and validation purposes. Simulation capabilities of the newly developed model were compared against the original lane-changing model in CORSIM. The results indicate that the new model better replicates the observed traffic under different levels of congestion.
