Time is a limited and valuable resource. As much as possible, people should spend the precious hours of their lives in the most satisfying and productive possible ways. This has important implications for transportation planning, since most people spend a significant amount of time in transport, and travel time savings are often the greatest projected benefits of transport projects such as roadway and transit service improvements.
You really need to almost get hit by a car to feel like a true Johannesburg pedestrian. That's the way it goes here. A huge, sprawling greater metropolitan area of about 10 million people covering more than 600 square miles, the city is built for the car. And if you're not in one, good luck.
Most North American cities offer only basic public transit service, with limited coverage and frequency, modest speeds, unattractive waiting areas, poor land use integration, and few amenities. Such service is used primarily by people who lack alternatives. In such communities, riders tend to abandon public transit as soon as feasible.
I’m going to riff off a recent Interchange Blog post by Michael Lewyn on the relationship between mobility and accessibility. Given the positive comments from the planning community to Michael’s post, a little engagement may be necessary for both clarity as well as fully understanding the implications of reading too much into the accessibility versus mobility debate.
