Support for AASHTO Committees and Councils. Roadmap for Integrated Selection of Multimodal Facilities

Our highway system now supports more uses than ever before, creating the need to balance them all within the limited space of the roadways. While the increase in types of use the roadways supports is beneficial to the health, economy, and resiliency of the transportation network, it also creates a substantial challenge to meet the needs of all roadway users. Currently, a typical way to decide how to build a multimodal facility is to use multiple American Association of Highway and Transportation Officials (AASHTO) publications focused on individual modes of travel. As several of these are independent documents focused on specific modes, there is an opportunity to review how these documents might more effectively inform decision makers in a more integrated approach. Furthermore, given the timing of the various design manual updates can lead to missed opportunities for the coordination of common elements in each document. Streamlined guidance at the national level may help avoid future repetitive updates that take years of overhaul, dedicated staff time, and financial investment. Current and forthcoming AASHTO publications (e.g., A Policy on Geometric Design of Highways and Streets; Guide for the Development of Bicycle Facilities; Guide for the Planning, Design, and Operation of Pedestrian Facilities) include new planning and design concepts for motorized and nonmotorized users on streets and highways. To support these publications, there is a need for a comprehensive approach to guidance and training material that would give planners and designers direction on developing a holistic process to choose a multimodal facility in one consolidated document. The objective of this project is to produce a roadmap to establish an integrated selection process for multimodal facilities for developing transportation infrastructure projects. This research would suggest strategies directly correlated with AASHTO strategic safety plans and initiatives to reduce serious injuries and fatalities while planning and designing safer roadways for all and streamlining and strengthening decision-making for multimodal facility selection. The outcome of this research will be a roadmap to establish an integrated selection process for multimodal facilities using all relevant AASHTO and related design guidance documents. Using this roadmap should enhance the safety and mobility of the traveling public across all modes and aid planning and design practitioners by removing silos when considering all roadway users in developing transportation infrastructure projects.
