Developing a unified method of measuring walkability: Quantitative measurement from qualitative assessments

“可步行”一词最近被用来定义城市街道人行道的性能水平。然而，挑战在于“步行能力”的衡量。由于这种测量具有主观性和定性的性质，因此有必要制定一种系统的程序，以产生有效和可接受的测量。斯坦泰克资产管理集团在加拿大各地的工作包括评估市政当局的人行道问题(如裂缝、绊倒危险、维修不善)，并打算开发一种基于适当的步行能力测量的改进人行道评估工具。可步行性测量并不容易，因为它涉及一组定性测量，例如可访问性、连通性、舒适性、愉悦性、气候、背景和交叉路口。这些定性措施中的每一项都通过若干替代指标得到进一步反映。然而，定义一个统一的度量，通过以下方式考虑所有这些定性度量

The term 'walkability' has recently been used to define the level of performance of sidewalks on urban streets. However, the challenge is the measurement of 'walkability'. Since, this measurement in subjective and qualitative in nature, it is necessary to develop a systematic procedure that can generate valid and acceptable measures. Stantec's Asset Management Group's work across Canada involved the assessment of sidewalk distresses (e.g. cracks, tripping hazards, poor repair) for municipalities and intend to develop a refined sidewalk assessment tool based on appropriate measurement of walkability. Walkability measurement is not easy as it involves groups of qualitative measures e.g. Accessibility, Connectivity, Comfort, Convivial, Climate, Context, and Crossings. Each of these qualitative measures is further reflected through a number of alternative indicators. However, defining a unified measurement that considers all of these qualitative measures through
