Enabling cycling at the home side or at the activity side of transit trips has been recognized as a promising solution to address transit network discrepancies and enhance connectivity between residents and employment opportunities. However, this multimodal solution is conditional to bicycle parking and cycle lanes, and urban planners need tools to identify relevant locations for these infrastructures. This research presents a novel method to quantify the impact of potential cycling infrastructures on job accessibility. Using a logsum-based indicator, we assess the spatial distribution of accessibility improvements across neighborhoods when residents have the option to cycle from and to transit stops. Then, we quantify the individual contribution of every potential bicycle parking location and cycle lane to the overall accessibility improvements. The proposed approach offers valuable support to urban planners in identifying the best locations for (1) multimodal bicycle parking and (2) cycle lanes to foster synergies between cycling and transit. To demonstrate the efficacy of our method, we apply it to the case study of Amsterdam. The findings reveal that bicycle parking at metro stops and cycle lanes connecting these stops to dense and remote locations contribute the most to accessibility improvements, as they effectively connect these areas to high-frequency and high-speed transit lines. Additionally, we observe that few strategic infrastructures account for most of the accessibility improvements in Amsterdam.

协同自行车和交通：自行车基础设施的战略布局，以提高就业机会

在交通出行的家庭一侧或活动一侧启用自行车已被认为是解决交通网络差异并增强居民和就业机会之间连通性的一个有前途的解决方案。然而，这种多式联运解决方案是以自行车停放和自行车道为条件的，城市规划者需要工具来确定这些基础设施的相关位置。这项研究提出了一种新颖的方法来量化潜在的自行车基础设施对工作可达性的影响。使用基于对数和的指标，我们评估当居民可以选择骑自行车进出公交站点时，各个社区的可达性改善的空间分布。然后，我们量化每个潜在自行车停车位和自行车道对整体可达性改善的个人贡献。所提出的方法为城市规划者确定（1）多式联运自行车停车场和（2）自行车道的最佳位置提供了宝贵的支持，以促进自行车和交通之间的协同作用。为了证明我们方法的有效性，我们将其应用于阿姆斯特丹的案例研究。研究结果表明，地铁站的自行车停放处以及将这些站点连接到密集和偏远地区的自行车道对改善可达性贡献最大，因为它们有效地将这些区域与高频和高速交通线路连接起来。此外，我们观察到，很少有战略基础设施对阿姆斯特丹的可达性改善做出了贡献。
