Time and spatial dependent activities and travel choices: results from Santiago de Chile

Abstract

Based on the choice for an activity plan (number and sequence of activities) we calculate complete activity trip trajectories, denominated as spatial paths. Each path represents the interdependency of activities and trips and includes choices for locations and modes. We introduce a methodology to reduce the spatial search for secondary activity locations and constrain spatial paths against daily travel time budgets. The application is illustrated for an activity plan of type ‘Home-Work-Shopping-Home’. As main information sources we use an existent trip demand model to reproduce the long term decisions for work and education locations and Santiago’s Travel and Household Survey to describe the characteristics of conditional secondary activities. We show results of the calculations of spatial paths and validate them against the empirical data base. The approach is currently under development for the area of Greater Santiago, Chile.
