GARMIN FRANSON GPSGATE SOFTWARE
I installed a software package called Franson GpsGate which can be configured to receive the data from the GPS hardware, and then output it in a variety formats/protocols. The GPS sensor that we used was the Garmin GPS18x that connects to a PC by USB. I wrote two small C++ programs for this project, one to be used during the experiment and one for post-processing. I was also tasked with marking the locations of the speed bumps in the data in some way. My responsibility on the project was to manage the data from the video camera and the GPS, and to ensure that their data could be synchronized with the string potentiomter data.
For two weekends we instrumented the buses on Saturday and drove the buses over the various types of speed bumps on the Sunday. The data acquisition equipment that we used included string potentiometers on the wheel suspensions, accelerometers at various locations inside the bus, a GPS unit mounted on top of the bus, and a camera mounted behind the driver. TheĬity of Ottawa was interested in installing more speed bumps in residential neighbourhoods and the city bus service, OC Transpo, was concerned about the effect this would have on their buses. In the fall of 2015 my research group at Carleton Univeristy was involved in a data gathering project with the goal to assess the effects that various types of speed bumps have on city bus ride quality.
