My recent exchange with Jarrett Walker (see Jarrett's original post, then my reply, and Jarrett's response) about the concept of mobility has encouraged me to update my chart of the transportation cycle.
The discussion with Jarrett has allowed me to split the notion of transportation quality or value into two parts, mobility and comfort. What I've realized is that while mobility for all is important to me, comfort for all is a much lower priority. I think government should make it affordable for everyone to travel reasonable distances to jobs, shopping and other activities, but I don't think that subsidized travel needs to be particularly comfortable. Of course it would be nice, but heading off global warming is a higher priority for me.
However, when transit offers equal or better mobility compared with private cars (as it does in many parts of New York), then comfort can be the deciding factor. So both factors influence mode choice.
I've also redone the chart in Gimp, instead of the original MS Paint, which gives me cleaner lines. Hope you all like it.
