Travel Demand Model Development Services

The Vendor is required to provide to a new validation year of 2025 using a new on-board transit survey, recent travel survey data, recent transit ridership, and 2025 traffic counts.
- Must perform highway and transit assignment, validation, and sensitivity testing using provided 2025 traffic counts and transit ridership data.
- Model performance must be evaluated against provided highway and transit assignment validation targets and goals. 
- Must document the validation process and resulting performance measures and targets.
- Static model validation focuses on known conditions, but the important role of models is in forecasting travel behavior and travel demand for future scenarios. 
- For this reason, sensitivity testing (dynamic model validation) is an important component of model development. 
- Must propose and implement sensitivity tests for improving TRM Stakeholder confidence in the model outputs with respect to travel behavior, highway demand, and transit ridership for future year scenarios.
- In the current version of the model, local bus (LB) transit routes are coded to have a stop time of zero (0), and stops are accounted for through travel speed penalization. However, bus rapid transit (BRT) routes within the model are coded such that stops are associated with wait times of 0.5 minutes for both boarding dwell times and alighting dwell times.
- This penalizes BRT services in contexts where BRT stops are frequent.
- Must revise and standardize how all transit modes are coded in the model to ensure that modes are operationalized in a unified manner.
