The infrastructure for parking and parked cars themselves (e.g., parked cars blocking bike lanes and sidewalks or the visibility range) can lead to conflicts for pedestrians and cyclists. The perception of conflicts could discourage walking and cycling in neighborhoods and undermine municipalities’ efforts to provide more sustainable urban mobility. The aim of this study was therefore to analyze the effect of on-street car parking in urban neighborhoods on perceived parking and traffic-related conflicts. In addition, it examines in what way the intention to reduce one’s car use influences the perception of the conflicts (Stage Model of Self-Regulated Behavior Change (SSBC)). A household survey was conducted in the inner-city neighborhood of Frankfurt-Bornheim, Germany (N=1027). The residents most often observed the conflicts in which parked cars impeded walking and cycling as well as situations in which pedestrians felt threatened by cyclists biking on the sidewalk. Results from multiple linear regression models revealed that the influencing factors for the perception of conflicts were the use of different means of transportation and the intention to change one’s behavior (SSBC model) to reduce car use rather than car ownership. In addition, a resident’s age and household structure seemed to affect awareness of conflicts in which pedestrians and cyclists were involved. The results suggest a group-serving bias, meaning that the residents mostly observed those conflicts that they did not cause. A separate infrastructure for pedestrians and cyclists could help prevent most of the conflicts described in this study.

城市社区的停车和空间竞争：居民对交通和停车相关冲突的看法

停车和停放汽车本身的基础设施（例如，停放的汽车阻塞自行车道和人行道或能见度范围）可能导致行人和骑自行车的人发生冲突。对冲突的看法可能会阻碍社区步行和骑自行车，并破坏市政当局提供更可持续的城市交通的努力。因此，本研究的目的是分析城市社区路边停车对感知停车和交通相关冲突的影响。此外，它还研究了减少汽车使用的意图以何种方式影响对冲突的感知（自我调节行为改变的阶段模型（SSBC））。在德国法兰克福-博恩海姆的市中心社区进行了一项家庭调查（N=1027）。居民最常观察到停放的汽车阻碍步行和骑自行车的冲突，以及行人感到在人行道上骑自行车的人的威胁的情况。多元线性回归模型的结果表明，冲突感知的影响因素是使用不同的交通工具和改变个人行为的意图（SSBC 模型）以减少汽车使用而不是汽车拥有量。此外，居民的年龄和家庭结构似乎会影响对涉及行人和骑自行车者的冲突的认识。结果表明存在群体服务偏见，这意味着居民大多观察到的冲突不是他们造成的。为行人和骑自行车者建立单独的基础设施可以帮助防止本研究中描述的大多数冲突。
