  • Publication number: 20210072037
    Abstract: Disclosed is a system and method for the automated routing of people and materials from one location to another based on automated vehicle technology as it applies to bus transit, ridesharing and car sharing, and on multiple modes of delivery including rail, water, road and air. An optimal transit algorithm is employed that uses Degree of Circuity (DOC) and Maximum Degree of Circuity (Max DOC) to better refine transit network design and scheduling. The given Max DOC and computed shortest travel times are used to define the maximum acceptable travel time for each passenger or package (i.e., “transport item” as used herein). Using those maximum acceptable travel times for passengers and/or packages as constraints, optimal routings are developed for each primary transport hub, such as a train station, using the Simulated Annealing (SA) algorithm.
