Evaluation of Existing Smartphone Applications and Data Needs for Travel Survey, Project Summary.

摘要

Current and reliable data on traffic movements play a key role in transportation planning, modeling, and air quality analysis. Traditional travel surveys conducted via paper or computer are costly, time consuming, and labor intensive for survey conductors; and place a significant burden on the survey participants. Furthermore, accuracy and completeness are susceptible to participants’ after-fact memory. To address this issue, this project evaluated existing smartphone applications for conducting travel surveys.
