  • Simulation-based map validation
    Patent number: 11475182
    Abstract: A method includes defining a simulated transportation network based on a map that represents a real-world physical transportation network. The simulated transportation network includes segments, and each segment includes information that describes operating characteristics for the segment. The method also includes defining simulated users and performing a simulation in which the simulated users are moved relative to the simulated transportation network. The simulated users are moved using control instructions, and the simulated users are moved based on the information that describes operating characteristics for the segment that corresponds to a respective current location for each of the simulated users. The method also includes identifying map errors based on the simulation.
