2.2.4 Fleet management

Wireless tracking devices fitted to vehicles can strengthen the efficiency of fleet logistic operations,
while reducing energy consumption and GHG emissions. These tracking devices can feed data to
centralized fleet management software or to other vehicles in the fleet. In addition to location, they
can also be used to remotely monitor loading capacities, enabling vehicle loading optimization. For
example, the vehicle’s route can then be adjusted to make use of spare capacity. Further benefits
can arise in SSC where wireless devices can be used in applications such as traffic volume
monitoring, connected road signs and traffic light synchronization. Such wireless devices are part of
the intelligent traffic control (ITC) system. The impact of GHG savings of smart transportation and
logistics, and smart grids and smart meters, have been estimated for different regions around the
world, as illustrated in Figure 5.
