Abstract

A system for mapping the occurrences of predetermined events or conditions along a transport route travelled by a mobile sensing station includes a central controller connected to the mobile sensing station over a first communication system such as a satellite communication system. The mobile sensing station continuously detects for occurrences of predetermined events or conditions so that a real-time indication of transport route conditions can be provided to a remote user connected to the central controller. The transmission of data regarding the occurrence of the predetermined conditions, time and date data corresponding to those conditions and positional data also corresponding to those conditions can be triggered using a variety of techniques.
