The walk a map leaves out.

In my February notes from Singapore, the walk home after class was three or four kilometres. A free day could stretch to more than twenty thousand steps in Sentosa. Those numbers sit beside each other quite neatly. The days they describe feel different: one walk fits around a class, while the other can fill an afternoon.¶

That difference is a useful place to start when I look back at our Cornell greenway project. The team report turns several groups’ needs into measures that can be compared across designs. On paper, that gives a reviewer a way into thousands of candidates. Back on foot, I find myself asking what each measure manages to carry from the experience it represents.¶

Take two imaginary routes to the same door. One is shorter, with a long exposed stretch and a crossing that asks you to wait. The other adds a block but offers shade and a place to sit. On a rushed morning I might take the first. With time to spare, I could choose the second. Someone who needs a rest halfway might have little choice at all.¶

A first pass would keep the extra distance, crossing wait, shade and places to rest in separate columns. A single score can help compare options later. Keeping those observations visible gives a reader a chance to ask why a few minutes of waiting count more or less than a stretch in the sun, and for whom.¶

If I were revisiting a route for a field check, I would try it in both directions at two times of day. I would mark where a decision actually happens: where I cross, where the shade ends, and where I can stop. I would keep those observations separate from my impression of the whole walk. A second person might notice a kerb or a crowded stretch I walked straight past.¶

This is what I like about putting the Singapore notes beside the old coursework. The city walk gives me a concrete way to question a model. The model, in turn, gives me a better question to carry on the next walk: where would this route become easier, and for whom?¶
