Abstract
This project developed an integrated Global Positioning System–geographic information system (GPS-GIS) to automate the processing of GPS-based personal travel survey data. Two versions of the analysis system were developed in this project: a GPS-alone system, which uses only GPS travel data as input, and a GPS-GIS integrated system, which uses both GPS travel data and topologic information on GIS platform as input. The GPS-alone system includes an activity identification algorithm and a fuzzy logic–based mode identification algorithm. The GPS-GIS integrated system includes link identification on a GIS platform as well as an interactive link matching-mode identification subsystem, which further refines the results from previous identifications performed separately. This project demonstrates how GPS travel data analysis can be automated and highlights the benefits brought by an interactive analysis system, providing an innovative analysis method for personal-based GPS multimodal travel surveys.
