Infraestrutura cicloviária em Manaus (AM):análise da pavimentação da ciclofaixa na avenida Nathan Xavier de Albuquerque

Abstract

Bicycle infrastructure plays a crucial role in promoting sustainable urban mobility and cyclist safety. Geometric design, road surfaces, drainage, signage, and lighting on bike paths are essential elements to be considered to ensure the safety and comfort of cyclists. Asphalt coatings used on bike paths can present pathologies such as cracks, potholes, sinking, disaggregation, slippage, and undulations. These failures compromise the structural and functional capacity of the pavement, negatively affecting the movement of users. This study aims to assess the state of conservation of the bicycle infrastructure on Nathan Xavier de Albuquerque Avenue, located in the Novo Aleixo neighborhood in Manaus (AM), observing compliance with current legislation and the preservation of the asphalt coating. The adopted method followed the guidelines of NORMA DNIT 006/2003 - PRO to determine the degree of degradation of flexible pavements, and the data were collected through on-site visits to evaluate the pavement and signage, the geometry of the bicycle infrastructure, and integration with other infrastructures. The data indicated a moderate level of pavement conservation, poor signage conditions, and it was observed that, although both ends of the analyzed bike lane are close to other road infrastructures, there is no connection between the installed sections. This would allow for greater coverage and mobility for users of the cycling mode.
