在日常活动中，人们有时会在一个方向上选择与回程时不同的路线。然而，我们并不完全了解人们选择特定路线的程度，而且这种不对称性尚未得到系统量化。为了解决这些问题，我们在大学校园中设计了一条多路段路线，其中包括两对相互路段，其中年轻成人参与者（n = 52，年龄 18-23，36f/16m）从地点 A 步行到地点 B，然后在路线中从地点 B 步行到地点 A，而没有意识到其相互性。我们使用 GPS 跟踪来记录参与者走过的路线，并开发了新颖的连续路线测量方法我们用相异性来分析互惠和非互惠路线。我们的结果表明，路线选择存在很大的不对称性，但个体参与者没有一致地选择对称或不对称路线的趋势。我们还发现参与者在所有路段所采取的路线上存在很大差异，但路线的这种自然变化并不能完全解释我们观察到的不对称性，这表明路线选择中存在系统性不对称性，超出了简单地采取可变路线的倾向。总体而言，我们对路线选择的对照测试平衡了实验控制与生态有效性。结合我们对路线（不）相似性的新颖测量，这些发现为这个经典的路线选择问题提供了新的视角。
During everyday activities, people sometimes take a different route in one direction than they do on the return trip. Yet we do not fully understand the degree to which people choose particular routes, and this asymmetry has yet to be systematically quantified. To address these questions, we designed a multi-segment route on a college campus that included two pairs of reciprocal segments, in which young adult participants (n = 52, ages 18–23, 36f/16m) walked from place A to place B and then later in the route—without being alerted to its reciprocal nature—went from place B to A. We used GPS tracking to record the routes our participants walked, and we developed novel continuous measures of route dissimilarity which we used to analyse both reciprocal and nonreciprocal routes. Our results indicate that there is substantial asymmetry in route choice but no consistent tendency for individual participants to take symmetric or asymmetric routes. We also found substantial variation across participants in the route taken across all segments, but this natural variability in routes did not entirely explain the asymmetries we observed, suggesting that there is systematic asymmetry in route choice that goes over and beyond the tendency simply to take variable routes. Overall, our controlled test of route choice balanced experimental control with ecological validity. Combined with our novel measures of route (dis)similarity, these findings provide a new perspective on this classic route choice problem.
