The complex spatio-temporal behavior of traffic flow has been extensively studied in the last decades. However, most research has primarily focused on freeways, or at most, on urban networks whose facilities are clearly stratified according to their functionality – freeways, arterials, collectors, and local roads. Research studies on urban reticulated networks, in which several facilities are barely distinguishable with respect to their type of use, have been largely neglected. This paper presents a spatio-temporal traffic volume pattern analysis of a such network, located in a large urban area in Brazil, considering a broad range of time (year, month, day of week, time of day) and space (network, arterial, direction, link) scales. Understanding these patterns significantly improves the effectiveness of urban traffic control (UTC) analysis and operations, supporting both short- and long-term congestion-reducing strategies.
