Abstract
At the beginning of the 21st century. clear indications of a paradigm shift in travel demand models are apparent. A growing number of cities are abandoning established traditional modeling techniques and exploring Activity-Based modeling approach. The Activity-Based (AB) models are characterized by such distinctive features as the use of tours instead of trips as the base unit of travel; the generation of travel in the framework of daily activity agendas of individuals, and the use of fully disaggregate Micro- Simulation techniques instead of the aggregate zonal calculations. These models have been found to be successfully used to address different planning questions and policy options which simply could not be credibly evaluated with traditional Four-Step models. In essence, the major benefit by more precisely tracking the factors that influence trip-making patterns such as accessibility constrains and coordinated trip-making behavior. For urban areas in developing countries, the travel demand models have to be expanded beyond the issue of simple traffic projections. Recent researches have recommended that accessibility constraints in developing countries should be incorporated in modeling urban travel behavior. The Activity-Based modeling approach has emerged at a potentially more suitable tool for treating the accessibility constrains than the traditional trip-based approach. The main objective of this thesis is to develop a comprehensive Activity-Based modeling system for urban areas in developing countries. A household survey of daily activity patterns is developed for Port Said (PS) city in Egypt as a case.
