The objective of this work was to develop a GPS device that would be much smaller and more lightweight, providing easy portability, so that it could be carried by respondents in a survey. The device would need to have a form factor that made it acceptable for people to carry it with them, needs to be self powered, and must have the storage capacity to store the data that would be collected from a week to a month of travelling with the device. Such a portable device would also offer potential to be applied in a number of other interesting applications, such as being used on board vehicles to track the vehicle routes and performance, etc. The device would also need to be deployed, to find out whether or not it would be accepted by the public, and whether it could record adequate data on travel.
