It is well-agreed by experts that it is no longer sustainable to have transport systems relying primarily on privately-owned vehicles to serve the travel demand. Fortunately, emerging technologies have allowed the development of new solutions and services for urban travel. These emerging mobility systems, such as on-demand for-hire vehicles (Uber, Lyft, etc.) and connected and automated vehicles, are becoming part of the urban landscape. To develop policies and management strategies to serve society best, we must understand the interactions of emerging mobility systems with traditional transportation modes, e.g., transit systems and privately-owned vehicles. To do so, we need models that can capture the interaction between transportation modes, their impact on traffic dynamics (travel speed, congestion patterns, etc.), and the impact of traffic dynamics on the mode and departure time choice. Such models will enable policymakers to explore various solutions to transportation challenges. Most current simulation models incorporating multi-modal transport require a lot of data collection and computational costs to simulate a specific network system. Consequently, insights and conclusions are often site-specific and, therefore, can rarely be extended to other regions when studying transport management strategies for high-level policy questions.
In recent years, there has been increased attention to very aggerated models that can capture the traffic dynamics in an urban zone as a queueing system. These models are referred to as bathtub or reservoir models and are built on several assumptions, see foreword in Vickrey (2020). The speed of the vehicles in that zone is determined by the so-called macroscopic or network fundamental diagram, see Johari(2021). With this model, one can treat the network as an undifferentiated unit and disregard the physical locations of numerous vehicle trips traversing the network. Such models are simple and can be solved numerically in a very efficient computational way. Although most literature studies consider continuum bathtub models, one can also take the trip perspective. This is very important to be able to study individuals' experiences and decisions when designing management strategies at the network level (e.g., pricing strategies) to improve the overall transportation system. This PhD project will be focused on developing an agent-based simulation model for multi-modal transport systems based on the assumptions of the bathtub models. The agent-based bathtub model will capture trip chains for individuals across modes and regions and will be used to design planning and management strategies for high-level policy questions.
