Activity-Based Travel Demand Modeling for Metropolitan Areas in Texas: Software Related Processes and Mechanisms for the Activity-Travel Pattern Generation Microsimulator

摘要

The Comprehensive Econometric Microsimulator for Daily Activity-travel Patterns (CEMDAP) is the microsimulation implementation of the activity-travel modeling system developed for metropolitan areas. Given various land-use, sociodemographic, activity-system, and transportation level-of-service attributes as input, the system provides as output the complete daily activity-travel patterns for each individual in the sample households. This report describes the software development process. The steps involved in applying CEMDAP to predict activity-travel patterns and to perform policy analysis are also presented. Empirical results obtained from applying the software to the Dallas/Fort Worth area demonstrate that CEMDAP provides a means of analyzing policy impacts in ways that are generally infeasible with the conventional four step approach.
