Abstract:

In this study, a fuzzy logic-based modeling framework is proposed to capture car-truck interactions from a non-truck driver perspective using measurable variables. This is done by introducing the notion of “discomfort” in the vicinity of trucks and using it to extend existing microscopic traffic flow modeling logic. A new parameter called driver discomfort level is proposed to incorporate the various factors that affect individual driver actions/interactions in this regard. Further, it is important to characterize the effects of these interactions at a system level to address real-world problems. Hence, there is a need to benchmark alternative mitigation strategies from the perspective of driver discomfort in addition to system performance and safety. Alternative supply-side strategies to mitigate car-truck interactions on freeways are identified and evaluated using an agent-based simulation platform. Insights are obtained using a case study involving the Borman Expressway (I-80/94) in northwest Indiana.
