Humans still have an edge over computers when it comes to navigating a city. In areas we are familiar with, we know precisely the cadence of traffic, when to avoid the subway, when biking makes sense, and how that all fits with the current weather and our moods. We have transit intuition, which is why we get so frustrated when Google Maps suggests a route that just doesn’t match the available options to get around.

Yet, even humans are starting to break down under the increasing complexity of mobility options. Whether its subways or buses failing or new options like bikeshares, electric scooters, or crowdsourced bus routes becoming available, our intuition on how to get to our destinations can be out-of-date or quite simply wrong. In the patchwork quilt of transit options available in most American cities, people often need to take two or even four different modes of transit just to get to their final destinations.
