Transportation systems typically span multiple jurisdictions, serve common markets, and often provide overlapping services within regions and corridors. The majority of research for developing transportation system performance management highlights the tools, frameworks, and guidelines necessary for performance program creation and implementation. Absent from this research is the examination of integrating system-level programs to measure the performance of multimodal and multi-jurisdictional transportation networks. There is a need for network performance measurement to efficiently plan for and manage a multimodal and/or multijurisdictional transportation network.
Whether individual systems are owned, operated, and maintained by state, regional, or local governments; specially designated authorities; or the private sector, users expect to navigate among the systems without regard to the controlling entity—having the appearance of a “seamless” transportation network. Performance evaluation of individual systems alone is not sufficient. What is needed is in-depth analysis of the potential for integration or development of performance measures to gauge the performance of multimodal and multijurisdictional transportation networks. Once an understanding of network performance is gained, results can be used to inform and improve planning, project selection, implementation, and management.
This research produced a guidebook that presents methods for integrating performance measures from individual transportation modes and multiple jurisdictions, and for developing new measures, if needed, to monitor transportation network performance.
