Research & action

TRAISI was deployed during the COVID-19 pandemic and collected datasets which reflected pandemic-influenced activity-travel behaviour. The survey was named the COVHITS.

TRAISI was deployed in 2019 to collect the activity-travel behaviour of post-secondary students in the Greater Toronto and Hamilton Area (GTHA). The survey is named the Student Move TO (SMTO) survey. The dataset was used to correct errors in the regional household travel survey in the GTHA.

The COVHITS dataset collected using TRAISI was used to investigate the issue of survey dropout from household travel surveys.

The SMTO dataset collected using TRAISI was used to model the impact of forced telecommuting during the COVID-19 pandemic.

TRAISI was developed to have the ability to collect location history data from Google Maps. The survey is named the Google Timeline Travel Survey (GTTS).
