Coordinated Daily Activity Pattern (CDAP) ¶

Documentation Update Required

This component documentation needs to be updated based on the SANDAG ABM Model Design document to ensure accuracy. The current content may contain inaccuracies compared to the original CT-RAMP specifications.

SANDAG Design Foundation

TM2’s CT-RAMP implementation is based on the San Diego SANDAG design. Please refer to the SANDAG ABM Model Design document for accurate specifications.

Status: Pending Update ¶

This component documentation is scheduled for update with accurate specifications from the SANDAG CT-RAMP design document. The update will include:

Correct model structure and formulation
Accurate choice alternatives and utility functions
Proper behavioral assumptions and market segmentation
Valid input/output specifications
Correct estimation and calibration details

Component Overview ¶

The Coordinated Daily Activity Pattern (CDAP) model determines the daily activity pattern for each household member and coordinates these patterns across the household.

Model Type: To be verified against SANDAG design document Decision Unit: Household level with individual member coordination Purpose: Establish daily activity commitments before tour-level modeling

Temporary Reference ¶

Until this documentation is updated, please refer to: - SANDAG ABM Model Design Document - SANDAG ABM Model Estimation Document

Last updated: November 10, 2025 - Marked for SANDAG design alignment

Childcare Policy - Effects of childcare availability on activity patterns - Impact on parent work participation and coordination

Behavioral Research ¶

Household Decision-Making - Understanding coordination mechanisms in travel behavior - Gender roles and activity allocation within households

Life Course Analysis - How household coordination changes over the lifecycle - Adaptation to changing household composition and needs

Coordination Foundation

CDAP is fundamental to household-based modeling. Ensure coordination mechanisms are well-understood and calibrated, as they affect all subsequent household and individual models.

Complexity Management

Large households create computational challenges. Consider simplification strategies for households with 5+ members while maintaining behavioral realism.
