The Comprehensive Econometric Micro-simulator for Daily Activity-travel Patterns (CEMDAP) is a micro-simulation implementation of a continuous-timeactivity-travel modeling system. Given as input various socio-demographic, land-use, and transportation level-of-service attributes, the system provides as output the complete daily activity-travel patterns for all individuals of a population. This paper describes the current state of CEMDAP and highlights the salient features of the software. CEMDAP models not only the activity-travel pattern of adults, but also that of children, while incorporating the inter-dependencies between the activity-travel patterns ofchildren and their parents. The software implementation of CEMDAP has been developed using the Object-Oriented (OO) paradigm to support software extensibility and rapid implementation of system variants. Further, the implementation supports multithreading and data caching capabilities to enhance computational performance. The paper discusses these features, and also presents the results from an application of CEMDAP to the Dallas-Fort Worth area. Verification exercises establish the reasonableness of CEMDAP outputs.
