Increasingly, scholars suggest thinking of the street as a social space, rather than just a channel for movement. Studies that address the relationships between social behavior and environmental quality of the street tend to separate the study of physical features from land uses and hence do not address the interrelationships between behavioral patterns and physical features of the street and its sociability. This article is an empirical examination of behavioral responses of people to the environmental quality of neighborhood commercial streets. Structured and semistructured observations are used to study stationary, lingering, and social activities on three neighborhood commercial streets. Eleven land use and physical characteristics of buildings and the street are identified based on the literature review and extensive observations. These are measured and tested to understand which characteristics support stationary, lingering, and social activities. The findings reveal that people are equally concerned with the social, land use, and physical aspects of the street. Seating provided by businesses, seating provided by the public authorities, businesses that are community places, personalized street fronts, and sidewalk width particularly contribute to stationary and social activities on neighborhood commercial streets.
