Lesson 1Trip segmentation and geo-fence events: start/stop detection, dwell time, zone entry/exitLearn how location points form trips and stops using speed, ignition, and geofences suited to Eritrean roads. It includes detecting starts and stops, dwell times, zone entries and exits, and setup choices for different fleet types.
