Human perception of space is not purely metric. A stratified random sample of 102 people was asked to express a preference on four images. Each image had two street scenarios: one curvy, one straight, holding constant everything else. In average 80% of respondents preferred to walk along the sinuous route against the straight, to both: walk through and reach a destination. 15% chose the straight route, while for the 5% both routes were indifferent. The 57% also said to perceive the curvy route as shorter than the same metrical distance in the straight route; the 30% said the opposite, and for the 13% both routes were indifferent. This result is of interest for theories and models that assume that pedestrians perceive route angularity as a psychological cost: each time they must turn they have a negative mental effect, therefore, places requiring more changes of angle to be reached, are perceived and modelled as more distant. Route angularity and complexity-minimizing path suggest that pedestrians tend to reduce as much as possible the number and the angle of turns when selecting routes. A key point is: who is turning? The street or the pedestrian? And, in the case of the pedestrian, how much does the latter know the area, and/or how much the continuity of the turning route is legible, regardless the number and magnitude of the turns? Findings of this paper suggests that, ceteris paribus and for continuous/legible routes, pedestrians prefer curvy paths instead of straight and felt the former as shorter too.
