How Urban Noise Levels Affect Pedestrian Comfort and Behavior at the Manuel Olguín–Javier Prado Intersection in Surco, Lima, Peru (2025)

Abstract

Urban noise is a common problem in large cities and can affect how people feel and act when they walk. In Lima, Peru, traffic noise is very strong, especially in places with many cars and little traffic control. This study looks at how noise affects pedestrian comfort, emotions, and behavior at the Manuel Olguín–Javier Prado intersection in the Surco district. This area has heavy traffic, frequent car horns, and many pedestrians because it is close to a shopping center and a university. This research uses a mixed method approach. It combines pedestrian observation and short surveys. Observations were done at the intersection to see how people walk, cross the street, and react to noise. Surveys were given to 40 pedestrians who often pass through the area. The survey asked about noise levels, comfort, stress, and changes in walking behavior. The answers were studied using simple counts and common themes. The results show that most pedestrians think the area is very noisy and uncomfortable. Many people said the noise makes them feel stressed, tired, or tense. Because of this, they walk faster, stay more alert, or try to avoid the intersection. During the observations, many people were seen rushing, hesitating, or using headphones, which confirms the survey results. Traffic and car horns were the main sources of noise. This study shows that noise is an important part of the walking experience and should be considered in urban design. Better traffic control, less horn use, and more green areas could help reduce stress and improve pedestrian comfort. These results can help planners and designers create safer, calmer, and more comfortable streets in Lima and similar cities.
