Using Custom Transportation Data Collection Software withHandheld Computers for Education, Research, and Practice

摘要

In an effort to facilitate data collection for research, give students first-hand experience collecting data for course projects, and generate interest in the transportation field through outreach, the Portland State University Intelligent Transportation Systems (ITS) Laboratory has developed custom data collection software for handheld computers using the Palm OS platform. The software is designed to export the collected data to desktop computers in common file formats suitable for analysis in spreadsheet and geographic information systems (GIS) applications. Data collection problems addressed include recording position over time, recording the geographic location of features, and performing cumulative vehicle or pedestrian counts.
