GPS-ENABLED HOUSEHOLD TRAVEL SURVEYS SAMPLE SIZE

-> The Transportation Research Board report, "Sample Size Implications of Multi-Day GPS-Enabled Household Travel Surveys," summarizes a project that studied the design of household travel surveys. Multi-day travel surveys are now more feasible, given global positioning system (GPS) technology. This project explores if surveys using a GPS device provides less drop-off in response compared to travel diaries. This project also investigates the effects of using multi-day data for developing travel demand models and explores the impact of sample size on multi-day versus single-day surveys. http://bit.ly/2fPYEHk
