| Abstract: | This paper introduced a speed data collection method applying GPS and the data collection procedure. It explicated the vehicle-following method using GPS, and provided the resolutions of the problems encountered in the field survey. Also the feasibility and effectiveness of the vehicle-following method was proved in the field data collection. This paper is an exploration on the application of GPS in speed data collection, which will be a useful guidance for the data collection required by the further research on operating speed. |
