The town of Pitesti lies at the confluence of Arges and Doamnei Rivers, on the coordinates 44*5′30″ wide, latitude North, 24*52′ long East, in Southern Romania. The objective of the study is the rehabilitation of urban infrastructure in Pitesti, targeting public space areas included between the buildings, bounded under study as follows: CENTRAL area, CALEA BUCURESTI area, TEILOR MARASESTI. The total area of intervention was 36,66 ha (48,17%) from the 76,102 ha (100%) studied. Territorial analysis focused on three systems: accessibility and mobility (to improve the existing network infrastructure, traffic and pedestrian safety); environmental systems and ecological networks (conservation of natural resources and environment and to create an ecological network, by the strengthening of existing ecological corridors); residential systems, services and urban centrality (i.e. balanced distribution of functions, meaning to locate central functional polarities allowing neighborhoods to be self-sufficient for basic needs of residents). The principles that are developed in the present paper and which constituted the premises of the planning process involved three levels of approach. AT THE CITY LEVEL, the project aimed at pursuing a constant coherence in the distribution of services and functions inherent to primary and secondary urbanization, spatial and formal coherence of mobility and accessibility, networks between different areas, expansion and achievement of an interconnection between ecological networks. AT THE ZONE LEVEL, the aim was to improve and streamline flows in networks linking districts and local areas in close proximity. It will also follow a consistent implementation and harmonization of urban functions and services in the area, taking into account the ecological networks and providing accessibility and mobility. AT THE SUBAREAS LEVEL, the aim was to improve the mobility and environmental quality of urban spaces, i.e. to create functional zoning and demarcation of their correct spaces, to rehabilitate planted and paved surfaces. © 2013 IAHS.
