Development of a vehicle ownership simulator within an agent-based integrated urban model

This study presents vehicle ownership (VO) simulation within the "STELARS' (Simulator for Transportation, Energy, LAnd use for Regional System) framework. VO is simulated as an event-based decision process adopting hybrid continuous-discrete time simulation techniques. In STELARS, each household agent subscribes to a list of events (e.g., child-birth) that makes them active to adjust their fleet. Being active, agents make two inter-connected decisions- vehicle transaction and type choices. In the vehicle transaction stage, for households never owning a vehicle, the first vehicle purchase timing decision is simulated. For households with vehicles, their decision to add, dispose, or replace a vehicle is simulated. In the vehicle type choice stage, agents' decision to choose vehicles by body, vintage, fuel, and technology type is simulated. Vehicle transaction is simulated as a continuous time decision using a hazard-based model. Once the timing of the transaction is determined, the vehicle type choice simulation transitions into a discrete time-step. This paper reports the micro-simulation of VO and multi-year validation for the greater Okanagan region in Canada for 2011-2021. Overall, the implementation of VOSim will assist in targeting the population groups and neighborhoods to develop equitable plans and policies to promote sustainable vehicle ownership.
