Distance to roads
Locating landfills near main roads has aesthetic problems for
passengers. This criterion was based on radial distances from
main roads (highways and main roads). Therefore, places farther
from main roads received a higher score. According to the landfill
siting regulations in Iran, the distance of a landfill to a main
road should be more than 300 m. Therefore, to evaluate this criterion,
300-m buffer zones were drawn around all roads. A score
of 2 was given when the landfill location to the roads was 300–
1000 m. The highest score (10) was assigned to a distance of
more than 3 km (Table 1); the results are shown in Figure 3.
