An Index To Quantify Street Cleanliness
Author(s)

Abstract
Street cleaning is an important facet of any solid waste management system, and
is directly related to public education and behaviour. Litter deposited on the
streets creates a negative visual impact, particularly on visitors. This indirectly
affects the economy and human health of the city. Unfortunately, very little
information is available in the literature on methods to quantify street
cleanliness. The Federación Española de Municipios y Provincias (Spanish
Federation of Municipalities and Provinces) has defined an index to evaluate the
quality of the street cleaning operations in its Guía Técnica para la Gestión de
Residuos Municipales y Limpieza Viaria (Technical Guide for Municipal Waste
Management and Street Cleaning). The Cleanliness Index varies in proportion to
the amount of litter on the street, but it is also related to the type of pavement,
climate conditions, and vehicle parking mode. This Cleanliness Index was used
to evaluate the dirtiness of a street in the city centre of Granada over an eight-day
period, at different times. This evaluation also took into account the activities of
the street population as well as manual sweeping practices. Since high levels of
cleanliness were detected in this street during the day, it was concluded that the
organization of manual sweepers is an important part of an effective system, and
depends on the frequency of sweeping. However, after the last sweeping event,
the dirtiness level increased considerably. Climate conditions during the study
increased the number people on the street at the end of the day, which resulted in
a higher value of the Cleanliness Index.
