Transportation researchers and planners have been attempting to use the smartphone-based travel survey for accurate data collection. Increasing the number of survey participants is important to obtain valid and effective results. Special attention is necessary for both the number of consenting participants and the number of respondents who sent data and remained until the survey completion. This study aims to investigate the data sending rate and survey completion rate of smartphone-based travel surveys. We conducted a smartphone-based travel survey in 2015 and two surveys in 2017, in Afghanistan cities. We improved the recruitment method in 2017; incentive provision, female survey conductors to recruit females, and assistance to use the application. It was found that these improvements significantly increased the data sending rate, but the effects on the survey completion rate were limited. Long-term smartphone owners and employed respondents were also found to stay longer in the survey.
