| 摘要： | The field of transportation modeling has seen many advances in recent years with approaches involving activity-based modeling and agent-based simulations. There have also been advances to the traditional four-step model, with researchers developing faster and more efficient sub-models. The basic structure of the four-step model, however, has remained fundamentally the same: trip generation, trip distribution, mode choice, and trip assignment. The long-lasting nature of this structure speaks not only to the model’s flexibility, but also to its transparency and (comparative) ease of use. Recent technological developments have led to the creation of whole new modes of transportation, such as ride-hailing services. Furthermore, the advent of self-driving automated vehicles (AVs) seem to be a tangible and concrete possibility the near future. In light of these changes, transportation agencies need to review and update their models to more accurately analyze future scenarios and plan accordingly. The main objective of this report is to document the changes made to the North Central Texas Council of Government’s (NCTCOG) four-step model in order to accommodate those two new features: ride-hailing services and AVs. |
