major streets of Riyadh and surrounding residential areas. We shall adopt a mathematical model to obtain noise
intensity level from the average number of passing vehicles in the road, their average speed and the percentage of
trucks. By using methods of spatial data insertion in GIS system, it was possible to prepare noise maps (continuous
area) which shows the nature and pattern of noise distribution in roads and surrounding areas, one set throughout
the day and another through peak hours.
These maps are useful for delineating areas with high noise level and areas of low noise levels. This
information, in turn, is useful for selection of sites for land uses that require low level of noise, such as health
facilities, schools, public libraries, etc.
By analyzing the relationship between noise and land use of areas surrounding roads, it was possible to know
the relationship between the activities and land uses of areas adjoining road, and the level of noise in the roads.
The spatial analysis was also useful in understanding the factors that lead to the high noise levels in some roads.
The conclusion contains recommendations and planning criteria that may help planners and decision makers
to reduce noise levels down to allowable levels, to preserve people's health and comfort and conserve the
environment.
