beaconing, and that the pickups also help in the detection, but only remove passenger
cars from the road, as well as light tow trucks. In addition, heavy tow trucks serve
buses and smaller trucks, and the super heavy tow trucks serve just big trucks. Table 3
shows the CO 2 emission per vehicle type used.
With these results, we can see that the assistances provided by heavy tow trucks,
followed by those assisted by super heavy tow trucks, are the ones that have the
highest average CO 2 emissions. Considering the maximum values, when analyzing
the database, we can note that the highest emissions in four cases were observed in
