The mobility of passengers and freight has very different spatial dynamics. While the intensity of passenger transportation is dominantly concerning short distances, freight transportation includes a wide range of ranges (geographies). The majority of the mobility of passenger movements is related to commuting, shopping, and recreation. These movements are dominantly bound by the time constraints of individuals who are unwilling to spend more than one hour per day commuting. It is only when passenger movements are less bound to time constraints, such as for business and tourism (when an individual has days instead of hours), that their geographical range can be extended.
Unlike passengers, most cargo does not have acute time constraints, although some like perishables do. This means that the intensity of freight movements has a much more significant variety of geographical conditions.
