TECHNICAL COMPLIANCE ASSESSMENT OF TRANSVERSE SPEED HUMPS ON URBAN ROADS: A CASE STUDY IN THE MUNICIPALITY OF ILHA SOLTEIRA, SÃO PAULO, BRAZIL

Abstract

Auxiliary traffic control devices play a relevant role in promoting urban road safety, particularly in speed control and traffic calming. Among these devices, transverse speed humps are widely used in urban areas, although their effectiveness depends directly on compliance with the technical criteria established by Resolution No. 600/2016 of the National Traffic Council (CONTRAN). This study aimed to assess the technical compliance of transverse speed humps installed throughout the urban road network of the municipality of Ilha Solteira, São Paulo, Brazil. The methodology was based on field surveys, photographic records, and the development of a georeferenced database within a Geographic Information System (GIS) environment using QGIS software. A total of 118 transverse speed humps were surveyed and classified according to the current regulatory standards. The results indicated that none of the analyzed speed humps fully complied with the criteria established by the legislation, presenting nonconformities related to geometric dimensions, signage, and location. Such inadequacies compromise road safety, traffic flow, and urban mobility. It is concluded that there is a need to review and adapt the municipality’s transverse speed hump system, as well as to ensure greater technical rigor in the implementation and inspection of these devices by public authorities.
