Some streets are genuinely unpleasant to walk along. I would want to see how certain areas or streets nudge path planning one way or another, as long term mildly repulsive or attractive forces. A street with wider sidewalks or quieter traffic conditions will draw people in. Above average urban noise and hostile street design will push them elsewhere. I don't think street construction or temporary inconveniences are going to influence the data too much. Full closures are uncommon as it's easy to maintain access for pedestrians (especially to abutting businesses) and pedestrians have infinitely more degrees of freedom than cars. No one's going to backtrack because they have to walk under scaffolding or a jersey barrier carveout in the street.
