Intersecting our mobilities: path dependence from manually-operated semaphore to self-driving vehicles?

Potential disruption stemming from self-driving vehicle (SDV) technology may change not just vehicles, but the foundations of our mobilities. As an example of analysing SDV technological development, this paper focuses on SDV intersection control. The starting premise is that technological development requires an understanding of previous developmental trajectories and potential future needs, rather than simply addressing present shortcomings. In order to investigate potential traps of technological path dependence, the paper examines the developmental trajectory of conventional traffic control technology. In addition, the paper contrasts stateof- the-research efforts for development of intersection control principles for SDVs. Finally, conclusive parallels are drawn for guiding the further development of SDV technology. Conclusions highlight the need for a wider deliberation and expansion of the criteria for foresight of mobility futures.
