Technology review and roadmap for inventorying complete streets for integration into pavement asset management systems

Complete Streets provide mobility for all modes of transportation
including active transportation.   Complete Streets are
being implemented in the US and transportation agencies must maintain
these assets, which requires bringing them into asset management systems.
Many gaps exist to include Complete Streets in asset management, and there
is no comprehensive plan for filling those gaps. This project developed a
road map to fill those gaps. To create this roadmap, the study completed
the following tasks: 1) develop and refine a survey 2) perform national
and in-depth surveys, 3) synthesize survey outcomes, 4) identify current
statuses, challenges, and needs, and 5) develop a roadmap for Complete
Streets asset management. All 50 state Department of Transportations
participated in the national survey while Caltrans, Georgia DOT, and the
Atlanta and Washoe County Metropolitan Planning Organizations contributed
to the in-depth survey. This report synthesizes the outcomes of the
surveys and literature review. The survey results showed that many
agencies have some Complete Streets guidance (39/50), but far less have a
dedicated liaison or office (15/40), and only seven agencies have Complete
Streets performance measures. The three primary challenges are: 1)
inadequate funding related to organizational structure 2) the need for a
rating system, and 3) the need for improved data accessibility, collection
methods, and management techniques. The proposed roadmap includes asset
management development and improved data collection and analysis pathways.
The roadmap is intended to be used as a starting point for the
incorporation of Complete Streets into asset management.

完整街道（Complete Streets）可为各类交通出行方式提供通行保障，涵盖慢行交通（active transportation）。目前美国正全面推行完整街道政策，交通管理机构需对这类交通资产进行维护管理，这要求将完整街道纳入资产管理系统（asset management systems）。当前在将完整街道纳入资产管理体系的进程中仍存在诸多短板，且尚无填补这些短板的综合性实施方案。本项目针对性制定了填补此类空白的路线图。
为编制该路线图，本研究完成了以下五项核心任务：1）开发并优化调研问卷；2）开展全国性调研与深度个案调研；3）整合调研所得成果；4）明确当前行业现状、面临的挑战与实际需求；5）制定完整街道资产管理专属路线图。
全美50个州的交通运输厅均参与了本次全国性调研，加州交通运输局（Caltrans）、佐治亚州交通运输厅（Georgia DOT）以及亚特兰大与沃肖县大都会规划组织则参与了深度个案调研。本报告整合了本次调研成果与相关文献综述的内容。
调研结果显示，多数交通管理机构已出台部分完整街道相关指导规范（39/50），但仅有少数机构设立了专属联络专员或专门办公机构（15/40），且仅7家机构建立了完整街道绩效评估指标体系。
当前面临的三大核心挑战分别为：1）受组织结构限制导致的资金投入不足；2）亟需建立标准化分级评级体系；3）亟需优化数据的可访问性、采集方法与管理技术。
本项目提出的路线图涵盖资产管理体系建设以及优化数据采集与分析路径两大模块，旨在为将完整街道纳入资产管理体系提供初始参考框架。
