How can design improve the safety of cyclists in shared transportation spaces?

Futurists interested in visualizing the state of societies in 2050 project that the cities of the future will have fewer cars within urban centers, prioritizing walkability, and will be dominated by forms of public transit, car-sharing services, and bicycles. Transitioning car-centric countries, like the United States to this preferable future is truly a wicked problem due to its complicated nature in which many systems, services, actors, and motivations are deeply intertwined and interdependent. As an avid cyclist, I am greatly invested in this issue. Moreover, my hometown, Pittsburgh, faces significant issues in making the necessary modifications to its infrastructure to transition to a more balanced and sustainable future.
