Public transportation is a critical component of cities' transportation system that can be supported by a safe, complete, and connected pedestrian infrastructure. Agencies spend millions of dollars each year to improve transit ridership, yet many of the transit destinations do not have adequate pedestrian infrastructure to connect to the transit stops creating a substantial barrier to growing demand. This is particularly true in suburban areas. This paper presents a replicable methodology for estimating relative parcel-level transit demand such that analysts can conduct fine-grained evaluation and prioritization of the pedestrian network enhancements as they relate to public transit system. To this end, pedestrian infrastructure can boost transit ridership and enhance riders' safety. We rely on spatial data available in most cities coupled with land use and socioeconomic data to generate potential relative number of walk-to-transit trips for each parcel and weight the occupied road segments based on the results from mode choice and gravity models. Using this GIS-based tool, we identify road segments that have a higher potential in serving as a walking path to transit stops and prioritize gaps in existing sidewalk infrastructure. This result eliminates arbitrary sidewalk investment scoring programs and the reliance on transit walksheds to direct investment. We apply this method to a case study of the city of Knoxville and discuss the challenges and possible solutions. This approach can help city planners and engineers in data-oriented investment strategic management of sidewalk enhancement programs that support transit.

公共交通是城市交通系统的重要组成部分，可以得到安全，完整且互连的行人基础设施的支持。代理商每年花费数百万美元来改善过境乘客量，但是许多过境目的地没有足够的行人基础设施来连接过境站，从而为不断增长的需求提供了实质性障碍。在郊区尤其如此。本文提出了一种可复制的方法，用于估算相对包裹级的公交需求，以便分析人员可以对与公共交通系统相关的行人网络增强功能进行细化评估和优先级划分。为此，行人基础设施可以提高过境的乘车率，并提高骑手的安全性。我们依靠大多数城市中可获得的空间数据，再加上土地利用和社会经济数据，来为每个地块生成潜在的步行至过境出行的相对次数，并根据模式选择和重力模型的结果对所占用的路段进行加权。使用此基于GIS的工具，我们识别出具有较高潜力的路段，可以作为人行道上的中转站，并优先考虑现有人行道基础设施中的缺口。该结果消除了任意的人行道投资计分程序，也消除了过境行人路对直接投资的依赖。我们将此方法应用于诺克斯维尔市的案例研究，并讨论了挑战和可能的解决方案。这种方法可以帮助城市规划人员和工程师进行以数据为导向的人行道增强计划的投资战略管理，以支持公交。
