Context-Sensitive Solutions in Practical Design

Context Sensitive Solutions (CSS) is an approach to transportation decision-making and design that takes into consideration the needs of the community as well as the sensitivity of the area for which the infrastructure proposal has been planned. CSS is the result of developing transportation projects that serve all users and that are compatible with the surroundings and environment through which they pass. Successful CSS is the result of a collaborative, multidisciplinary approach to transportation planning and project development. CSS within the transportation planning or project development process identifies objectives, issues and concerns based on interlocutor and community input at each stage of the planning process. The application of this approach at the initial design phase is fundamental for the evaluation of foreseeable impacts of both a positive and a negative nature. The final result of the CSS approach should be a better understanding of the links between our society, our natural environment and the sustainable use of our resources. A model is presented in order to support the CSS planning approach, it is a hierarchy model that aims to improve the plan performance by means of a series of evaluation criteria and attributes classified under 2 categories: technical and environmental macro-criteria. Generally, consultation activities are of great significance in order to achieve acceptance and to simulate the whole decisional process of a road project, the authors proposed an interactive consultation to two stratified samples thirty people each. The first sample was composed of people who were not experts in any particular field yet who had a high level of education, the second group was composed of experts in various fields such as: civil engineering, landscape and context design, economical, environmental and construction managers as well as different stakeholders. The objective of this investigation is to identify the key criteria and factors of decision-making models and their relative importance. In fact, questionnaires were prepared and different activities such as focused group discussions and interactive meetings were carried out during the study. The data collected was processed and analyzed by means of statistical control charts and the relative importance of such evaluation criteria was determined without considering scales by which the criteria was measured and a sensitivity analysis of weights was developed. The model was applied to a case study developed regarding the improvement of an intersection situated in the South of Italy. The alternatives developed by planners with the support of stakeholders were assessed according to the synthetic index performance and subsequently it was processed through the proposed model. The application of the model allowed the selection of the best solution for a sensitive area and the results confirm the suitability of both the model developed and the procedure performed. It is an useful tool to support CSS and by means of which to overcome the operational difficulties that emerge from the interaction carried out between the planning and evaluation activities.
