Abstract
In an effort to facilitate data collection for research, give students firsthand experience collecting data for course projects, and generate interest in the transportation field through outreach, the Intelligent Transportation Systems Laboratory of Portland State University, Oregon, has developed custom data collection software for handheld computers using the Palm OS platform.

Data collection problems addressed include recording position over time, recording geographic location of features, and performing cumulative vehicle or pedestrian counts.
