About

Ruth Madigan is a leading researcher in human factors and autonomous vehicle (AV) safety, with a particular focus on the complex interactions between AVs and vulnerable road users. Her most-cited work, "Empirical game theory of pedestrian interaction for autonomous vehicles" (2018, 42 citations), addresses a critical gap in AV development: while mapping and navigation algorithms are well-established, AVs often fail to negotiate shared spaces with pedestrians. Madigan’s research applies game theory to model these interactions, showing that overly cautious AV behavior—such as stopping every time a pedestrian approaches—can actually create confusion and inefficiency. This work has been foundational in shaping how engineers design AV decision-making algorithms to balance safety with social norms. Beyond this paper, Madigan has contributed extensively to understanding driver behavior, trust in automation, and the ethical implications of AV deployment. Her research is highly cited in both transportation and human-computer interaction fields, and she is recognized for bridging the gap between technical engineering and human-centered design. For students and researchers, Madigan’s work offers a compelling example of how empirical behavioral science can directly inform the safe integration of emerging technologies into everyday life.
