Activity Based Modeling
Activity Based Travel Demand Modeling System
Activity based travel demand modeling refers to disaggregated modeling of travel behavior to micro-simulate individual activity patterns.
The Baltimore Metropolitan Council is planning to improve its current travel demand-modeling system by developing an alternative set of models under the activity-based modeling framework. This will be a phased multi-year effort and a first step in transitioning has begun with the initiation of development of Synthetic Population Generator model.
Synthetic Population Generator Model
Within the context of an envisioned larger effort to develop a new activity-based travel demand model system, a team lead by Arizona State University has been awarded a contract to assist BMC in the development of a Synthetic Population Generator (SPG) model. In the interim, this project enhances BMC’s current trip-based regional travel demand model by developing a disaggregated socio-economic data set.
However, it is also the region’s first step in transitioning towards an activity–based microsimulation model system for travel demand forecasting. The goal of this project is to develop a synthetic population generator model in the context of a future Activity-Based Model development plan.
A two-day workshop on Synthetic Population Generator model and Activity Based modeling framework was conducted for BMC staff, representatives from partner agencies and stakeholders in November 2010. Workshop presentations are available in pdf format:
