Traditional travel survey methods have been widely used for collecting information about urban mobility although Global Position System (GPS) has become an automatic option more precise data of the households since mid-1990s. Many studies on patterns focused GPS advantages leaving aside its issues such as quality collected. However, when it comes to extract frequency trips and travelled distance, this technology faces some gaps due related signal reception time-to-first-fix location that turns out in missing observations respectively unrecognised or over-segmented trips. In study, we focus two aspects a car-mode, (i) measurement distance (ii) estimation factors influence gaps. To asses that, tracks are compared ground truth source. Additionally, analysed based land use (e.g. rural areas) length short, medium long trips). Results from 170 participants than year GPStracking show around 9 % is not captured by affects short ones. Moreover, validate importance time spent user activity GPS.
