The document discusses a trailer tracking system that provides executive summaries, maps, timelines, and graphs of key fleet data. It allows users to view trailer locations, activity, journeys, and maintenance records. The system collects basic data from trailers like GPS position, speed, load percentage, and mileage, as well optional data like tyre pressure and temperature. It is described as creating opportunities to reduce empty running hours and time spent loaded but uncoupled. The technology in the data collection units and web application is presented as the future of trailer management, with minimal investment but great return on investment.
