Abstract Walkable access is recognised as one of the most important factors for deciding to walk instead of using other modes of transport. Distance has been less accurately taken into consideration in previous walking accessibility measures, however, as they are often based on an isotropic approach or on a fixed distance threshold. The objective of this paper is to present a method of modelling continuous walking accessibility to different amenities in a city, with an integrated network-based and distance-decay approach, applied to a case study of the city of Ljubljana, Slovenia. The approach is based on a web survey to obtain data on acceptable walking distances to different types of amenities. Several distance decay functions were analysed for each type of amenity from the cumulative frequency of responses. The best fitting functions were used to model the walking accessibility surfaces for individual amenities in the network, representing five domains (retail, services, recreation, education and transportation) and an overall walking accessibility index. Despite certain limitations and a further need to assess the validity of the methods, our distance-decay network-based approach is more accurate than the isotropic or even network-based modelling of walking distances in continuous or threshold approaches, as it enables the researcher to take into account the differences in propensities to walk to different amenities. The results can be used by city authorities and planners for implementing actions to improve walking accessibility in the most problematic areas.

模拟步行可达性:斯洛文尼亚卢布尔雅那的案例研究

摘要步行通道被认为是决定步行而不是使用其他交通工具的最重要因素之一。但是,在以前的步行可达性措施中,距离的准确性较低,因为它们通常基于各向同性方法或固定的距离阈值。本文的目的是提出一种使用基于网络和距离衰减的集成方法对城市中不同设施的连续步行可达性进行建模的方法,该方法适用于斯洛文尼亚卢布尔雅那市的案例研究。该方法基于网络调查,以获取有关不同类型便利设施的可接受步行距离的数据。从响应的累积频率分析了每种舒适性的几个距离衰减函数。最佳拟合函数用于为网络中各个便利设施的步行可及性表面建模,代表五个域(零售,服务,娱乐,教育和交通)和整体步行可及性指数。尽管存在某些局限性,并且还需要评估这些方法的有效性,但基于连续性或阈值方法的基于距离衰减的网络方法比基于各向同性甚至基于网络的步行距离建模更为准确,因为它使研究人员能够考虑到步行到不同设施的倾向的差异。结果可被城市当局和规划者用于实施行动,以改善最有问题的地区的步行可达性。代表五个领域(零售,服务,娱乐,教育和运输)和整体步行可达性指数。尽管存在某些局限性,并且还需要评估这些方法的有效性,但基于连续性或阈值方法的基于距离衰减的网络方法比基于各向同性甚至基于网络的步行距离建模更为准确,因为它使研究人员能够考虑到步行到不同设施的倾向的差异。结果可被城市当局和规划者用于实施行动,以改善最有问题的地区的步行可达性。代表五个领域(零售,服务,娱乐,教育和运输)和整体步行可达性指数。尽管存在某些局限性,并且还需要评估这些方法的有效性,但基于连续性或阈值方法的基于距离衰减的网络方法比基于各向同性甚至基于网络的步行距离建模更为准确,因为它使研究人员能够考虑到步行到不同设施的倾向的差异。结果可被城市当局和规划者用于实施行动,以改善最有问题的地区的步行可达性。我们的基于距离衰减的网络方法比采用连续或阈值方法的各向同性甚至基于网络的步行距离建模更为准确,因为它使研究人员能够考虑到步行至不同便利设施的倾向的差异。结果可被城市当局和规划者用于实施行动,以改善最有问题的地区的步行可达性。我们的基于距离衰减的网络方法比采用连续或阈值方法的各向同性甚至基于网络的步行距离建模更为准确,因为它使研究人员能够考虑到步行至不同便利设施的倾向的差异。结果可被城市当局和规划者用于实施行动,以改善最有问题的地区的步行可达性。
