Coordinated Human Services Transportation Plan (CHSTP) Priority Score
收藏资源简介：
2024 Updates DVRPC performed an analysis to create the CHSTP Priority Score, a layer that helps users visualize where there is a potentially high need to improve transit service for vulnerable populations to reach essential services in the Greater Philadelphia region. As a metropolitan planning organization, Delaware Valley Regional Planning Commission (DVRPC) is responsible for updating the region's Coordinated Human Services Transportation Plan (CHSTP). The CHSTP update engaged a variety of stakeholders to identify unmet needs and service gaps, recommend innovative transportation access solutions, and empower communities to climb "ladders of opportunity" toward greater social and economic mobility. As part of the CHSTP update, DVRPC created the CHSTP Priority Score Map Toolkit. This interactive web-based tool demonstrates disparities in access to essential services like hospitals, health clinics, recreational spaces, senior centers, and more in the Greater Philadelphia region. Users can view layers representing different datasets including the locations of essential services; bus routes, transit stops, and rail lines; transit walksheds; distributions of vulnerable populations like seniors, households in poverty, and people with disabilities; and areas where transit access is low. https://github.com/dvrpc/gis-chstp includes all code for the analysis. Below are several of the analyses included in this dataset. Vulnerable Populations answers the question, “Who lives here?” and highlights populations in need. Essential Services answers the question, “Where do people need to go?” and highlights areas with more services in the region. Population-Services Mismatch answers the question, “Where is there a gap between areas of need and essential services?” This layer highlights areas where there are higher numbers of vulnerable populations but fewer essential services and vice versa. Transit Accessibility answers the question, “How is transit service distributed?” and highlights areas in the region with lower transit accessibility. Priority Score answers the question, “Where can transit service be improved to help vulnerable populations access essential services?” This layer, the result of our analysis, highlights areas with higher numbers of vulnerable populations or essential services, but lower transit accessibility and vice versa.

2024年更新：特拉华谷区域规划委员会（Delaware Valley Regional Planning Commission, DVRPC）开展了一项分析工作，旨在生成**CHSTP优先级评分（CHSTP Priority Score）**图层，该图层可辅助用户可视化大费城地区内，弱势人群前往基本服务设施时改善公交服务的潜在高需求区域。 作为大都会规划组织，DVRPC负责更新本地区的**综合人文服务交通规划（Coordinated Human Services Transportation Plan, CHSTP）**。本次CHSTP更新工作吸纳了多方利益相关者参与，旨在识别未被满足的服务需求与供给缺口，提出创新性的交通可达性解决方案，并助力社区搭建“机会阶梯”，以提升社会与经济流动性。 作为CHSTP更新工作的组成部分，DVRPC开发了CHSTP优先级评分地图工具包。这款基于网页的交互式工具，可展示大费城地区内医院、诊所、休闲空间、老年中心等基本服务设施的可达性差异。用户可查看多个代表不同数据集的图层，涵盖基本服务设施位置、公交路线、公交站点与轨道交通线路、公交步行可达区、老年群体、贫困家庭及残障人士等弱势人群分布，以及公交可达性较低的区域。 本分析的全部代码可通过https://github.com/dvrpc/gis-chstp 获取。 本数据集包含以下多项分析内容： 1. 弱势人群分析：回答“此地居住着哪些人群？”这一问题，重点标注存在服务需求的人群。 2. 基本服务设施分析：回答“人们需要前往何处获取服务？”这一问题，重点标注本地区内服务设施较为密集的区域。 3. 人群-服务错配分析：回答“需求区域与基本服务设施之间存在哪些供需缺口？”这一问题，该图层重点标注弱势人群数量较多但基本服务设施匮乏的区域，反之亦然。 4. 公交可达性分析：回答“公交服务的空间分布情况如何？”这一问题，重点标注本地区内公交可达性较低的区域。 5. 优先级评分分析：回答“在哪些区域改善公交服务可帮助弱势人群更便捷地前往基本服务设施？”这一问题。该图层为本次分析的核心成果，重点标注弱势人群数量较多或基本服务设施较为密集，但公交可达性较低的区域，反之亦然。 ### 字段说明 #### 弱势人群模块 - 家庭总户数（Total Number of Households, hh）：数据源为**美国社区调查5年数据（American Community Survey 5-Year Data, ACS）2018-2022**，对应字段ACS B11001_001E - 总人口数（Total Number of People, pop）：数据源为ACS 2018-2022年5年数据，对应字段ACS B01003_001E - 至少1名残障人士的家庭数（Households with 1 or More People with Disability, hh1_dis）：数据源为ACS 2018-2022年5年数据，对应字段ACS B22010，即“过去12个月内领取食品券/补充营养援助计划（SNAP）的家庭”估算值 - 贫困线以下家庭数（Number of Households Below Poverty Line, hh_pov）：数据源为ACS 2018-2022年5年数据，对应字段ACS B17017，即“过去12个月内家庭收入低于贫困线”估算值 - 65岁及以上人口数（People 65 or Older, _65older）：数据源为ACS 2018-2022年5年数据，按性别与年龄组汇总统计 - 弱势人群排名（Vulnerable Population Rank, vul_pop_rank）：由DVRPC自主计算得出 #### 基本服务设施模块 - 老年/残障人士活动中心数（Activity Centers for Seniors or Disabled, ss_cnt）：数据源为Overture地图（2024） - 食品店数量（Food Stores, food_cnt）：数据源为Overture地图（2024） - 医疗保健设施数（Health Care Facilities, hc_cnt）：数据源为Overture地图（2024） - 教育机构总数（Number of Educational Institutions, school_cnt）：数据源为**美国国家教育统计中心（National Center for Education Statistics, NCES）**，补充数据来源链接包括https://nces.ed.gov/collegenavigator/、https://nces.ed.gov/surveys/pss/privateschoolsearch/、https://nces.ed.gov/ccd/schoolsearch/ - 公园/开放空间存在情况（Parks/Open Space Present, os_check）：数据源为DVRPC 2016年公园与开放空间数据集 - 步道数量（Trails, trail_cnt）：数据源为DVRPC 2020年环区步道数据集 - 基本服务设施总计数（Essential Services Total, es_sum）：由DVRPC自主计算得出 - 就业岗位总数（Jobs sum_jobs）：数据源为美国人口普查局LODES（LEHD Origin-Destination Employment Statistics）数据 - 基本服务设施排名（Essential Services Rank, es_rank）：由DVRPC自主计算得出 #### 供需缺口模块 - 可达性缺口排名（Access Gap, access_gap_rank）：由DVRPC通过弱势人群排名与基本服务设施排名的差值计算得出 #### 公交可达性模块 - 公交可达性分区（Transit Accessibilty Zones, t_45min_zone_cnt; t_zone_quantile）：数据源为DVRPC 2023年交通模型，表征“乘客在45分钟公交行程内可抵达的区域数量” - 45分钟公交可达区内的基本服务设施与就业岗位（Essential Services in 45 minute TAZ zones, t_es_cnt; t_job_cnt; t_45min_es_job_avg）：数据源为Overture地图与DVRPC交通模型，将街区组内的就业岗位与其他基本服务设施按类别分组后取平均值 - 日发车总量（按交通分析区划分, Daily Departures (by TAZ), total_departures, depart_quantile）：数据源为**通用公交反馈规范（General Transit Feed Specification, GTFS）**，涵盖宾夕法尼亚州东南部交通局（SEPTA）、新泽西交通局（NJTRANSIT）及PATCO的公交服务频次数据 - 步行可达性排名（Walkability Rank, walkshed_quantile）：数据源为DVRPC步行网络及GTFS数据（SEPTA、NJTRANSIT、PATCO），表征街区组至公交站点的步行可达性水平 - 公交可达性排名（Transit Accessibilty Rank, transit_access_rank）：由DVRPC自主计算得出 - 优先级评分（Priority Score, chstp_score）：由DVRPC自主计算得出
