Abstract:This report expands on the work from a prior report Potential Categories for the Application of Blockchain in Intelligent Transportation Systems (ITS) (FHWA-JPO-23-987) by conducting a gap analysis on five selected distributed ledger applications from this report. The gap analysis was conducted by first determining the current state of these applications, (1) Multimodal Trip Planning and Fare Payment System, (2) Transportation-based Virtual Power Plant with Payment, (3) Freight Management, (4) Use-based Fees, and (5) Security and Credential Management (SCMS), and then determining the desired/future state of these applications based on stakeholder feedback and literature reviews. Gaps were then identified by determining what steps, if any, could be taken to get from the current state to the future state for a given application. Sixteen use cases were developed, providing real-world scenarios to illustrate how a distributed ledger could potentially or is currently being used to advance the current state of the five applications to their desired/future state. This document prepares technologists to evaluate and implement blockchain and distributed ledger-based solutions to make transportation infrastructure safer, more efficient, and with a positive environmental impact.
