Many engineers, planners, politicians, and other adults assume that transportation in cities has to be complicated. Yes, some aspects might be a little complicated. However, cycling and walking are relatively simple and are accessible to most people over five-years-old. Respectively, cycling and walking have been around for 200 years and for as long as our species has been on the planet. They are fundamental modes of transportation and are well suited for the majority of trips in cities and towns. The idea of proximity is also simple; that is bringing land uses, which people need routinely, close together. If we choose to design our streets to comfortably accommodate cycling and walking, while mixing and densifying our land uses in our cities so that most trips would be short enough to walk or bike, then our cities would be better off on a number of fronts. It’s actually quite simple. So, let’s work together and try to make things simple for a lot of people, shall we?
