ABSTRACT
The state-of-the-art of mobility services among large-scale agent-based travel demand models has focused predominantly on the demand side, whereas complexities of the supply side have been given much less attention. Conventional definitions must be revisited to establish solid foundations for model implementations. First, several mobility services are characterized from abstract attributes, by all agents involved, and by operational tasks involved in service provision. Then, a high-level generic service provision process is developed to allow instantiation of various services. Extensions for conventional travel demand model systems are also developed, including: a mobility services component containing service provider agentsand their operational tasks integrated logically into service provision processes; a fleet component containing vehicle agents of each service and a driver activity model when human-driven; a MaaS component containing mobility provider agents that coordinate and integrate mobility services. Generic modeling issues are also discussed, including treatment of time, data structures, and computational efficiency.
