No full textAs a case study, the Piazza Verbano, a residential district in Rome, built mainly during the 20's - 60's period is studied; its urban quality is linked, as usual, to mobility and relationship possibilities; here, the elderly can be chosen as elective users, not only because of their frailty, but also for their large consistency and moreover, for their being optimal users of all the area outdoor spaces, since they spend a lot of the spare time they have at disposal there. In the preliminary design, it is important to consider the individual's own decision making process about walking that, in the case of aged people, is mainly influenced by the space configuration and features. Thence, it is necessary to deal with two different aspects: the urban environment propositions and the people's expectations and cultural habits. Main classes of exigencies are investigated to determine the main requirements: Safety, meant as safeguard from traffic accidents and space use risks, and Security, as safeguard from unexpected events; Accessibility, as the full reachability and use of places, services, facilities and modal interchange points; and Comfort, as physical and psychological well-being, and moreover as commodity of movement and rest. Focusing on meeting these requirements as expressed by aging people, analyses were made on the spot, to enhance the real aspects of their mobility and lifestyle; for instance, for what concerns safety, several investigations have been run to individuate main destinations, meant as everyday poles of attraction, their related distances and the most usual paths; through them, the black points and the traffic dangers they have commonly to face have been determined, together with other aspects, such as uneven walkways or unsuitable lighting, that, besides affecting negatively safety, have no positive consequences on accessibility, security and comfort issues. The study on its whole is aimed at reshaping the intermediate public urban spaces, so to create a continuous pedestrian network that, offering besides accessibility and safety, also better comfort and a good identity and belonging feeling, in order to foster not only walking but also meeting and resting
How can urban rehabilitation meet the elderly pedestrian requirements? A comparison between research and practice
No full textThe study is characterized by the attention given to the implementation of a new mobility system and to the urban quality upgrading of the external spaces for pedestrians, in particular for the elderly and for the impaired people, in relation to their needs and to the location of different activities. In this design proposal, reorganisation possibilities and achievable qualitative levels prefiguration have been defined using a methodology which allows, by analysis and selection of consecutive steps, to compare residents' requirements to the performance of places, and so to individuate the needed adjustments in relation to the spaces new use. As a case study Pietra Papa in Viale Marconi has been chosen: a Roman semi-central area, built during the 60s, because of its negative features: accessibility and safety insufficiency, traffic and parking problems, functional and physical decay. The neighborhood lacks and potentialities have been analyzed; questionnaires and interviews have shown usual habits and gathering places; focusing on aged people, difficulties in handling with the surrounding environment have been detected as their main problems, especially in terms of traffic safety, of autonomy during their everyday trips, and of suitable spaces. They complain, indeed, the lack of meeting places where to stay far away from the cars and from the deafening traffic noise, and, first of all, of pedestrian paths fit for their needs. So, in order to comply with residents' wishes, a pedestrian paths system has been created, trying to link the most important attractions: the schools, the riverside, the local post office, the church, the elderly center, the area bus stops. To do that, the infrastructure has been remodeled thanks to some traffic calming devices (raised crossings, chicanes, cul de sacs, carriageway reductions), designed not only using alignment and profile technical solutions, but also environmental elements and techniques, such as landscaping, plantings, lighting, colours, materials and so on. The main axis, a central street of the area, is structured with a sequence of various spaces with different role
Proposta di intervento per la realizzazione di un sistema per la sicurezza della mobilità pedonale “Pietra Papa” Roma
No full textIl progetto pilota di riqualificazione del quartiere Pietra Papa a Roma ha consentito di verificare la fattibilità di una trasformazione funzionale ed ambientale del "suolo" della città individuando problemi, limiti e potenzialità di una pedonalizzazione diffusa e controllando le possibilità offerte dall'applicazione delle norme e delle tecniche attuate in Europa in materia di moderazione del traffico e sicurezza delle utenze deboli

No full textThis paper relates to a design proposal answering the call for tenders issued by the Italian Ministry of Public Works about "pilot projects", i.e. test innovative interventions and projects aimed at improving road safety and at reducing the number of fatalities. The proposal, here presented, refers to the class concerning "Urban areas and land structures", at the point "Change from extra urban to urban road system". It represents a typical case of a National road (with its heavy traffic and its safety problems) that enters an urban area without appropriate devices for alerting drivers of the change of context. Highways and streets should be designed to meet the requirements of their specific class of users; problems arise when the users' needs are in conflict. In this sense, the crossings of small towns by national highways are very critical spots, since the perception and the use of the same space is completely different for highway's drivers and local users. In the considered case study, the National Highway Salaria, a consular road, passes through the small centre Osteria Nuova, part of the little town of Poggio Moiano, without significant changes of the road's geometrical characteristics; as a result, the 50 km/h speed limit, signalised at the urban area entrance, is not considered by most of the drivers, who, according to the police measurements, cross the area at speeds often faster than 100 km/h. The accident rate is very high and the severity index is 100 higher than the national one. The aim of the intervention is to improve the safety level of the highway, both for drivers and pedestrians, by the implementation of a system of measures targeted to induce users (mainly car drivers) to behave in a more respectful way, according to the rules in force and to the road functional feature
