A fully separated bicycle network from vehicular traffic is not realistic even for the most bicycle-friendly cities. Thus, all around the world urban cycling entails switching between streets of different safety, convenience, and comfort levels. As a consequence, the quality of bicycle networks should be evaluated not based on one but multiple factors and by considering the different user preferences regarding these factors. More comprehensive methodologies to assess urban bicycle networks are essential to the operation and planning of modern city transportation. This work proposes a multi-objective methodology to assess—what we refer to as—bikeability between origin–destination locations and over the entire network, useful for evaluation and planning of bicycle networks. We do so by introducing the concept of bikeability curves which allows us to assess the quality of cycling in a city network with respect to the heterogeneity of user preferences. The application of the proposed methodology is demonstrated on two cities with different bike cultures: Amsterdam and Melbourne. Our results suggest the effectiveness of bikeability curves in describing the characteristic features and differences in the two networks.

即使对于自行车最友好的城市，将自行车网络与车辆交通完全分离也是不现实的。因此，世界各地的城市自行车都需要在不同安全、便利和舒适水平的街道之间切换。因此，自行车网络的质量不应基于一个而是多个因素进行评估，并应考虑用户对这些因素的不同偏好。更全面的评估城市自行车网络的方法对于现代城市交通的运营和规划至关重要。这项工作提出了一种多目标方法来评估（我们称之为）起点-终点位置之间以及整个网络上的可骑行性，对自行车网络的评估和规划很有用。我们通过引入可骑行性曲线的概念来实现这一点，该曲线使我们能够根据用户偏好的异质性评估城市网络中的骑行质量。在具有不同自行车文化的两个城市中展示了所提议方法的应用：阿姆斯特丹和墨尔本。我们的结果表明可骑行性曲线在描述两个网络的特征和差异方面的有效性。
