Reconsidering the conventional approach of transport planning, transport stake-holders have recently begun to shift their focus from the private car towards sustainable transport systems, among which walking is included. Planning and design of walking infrastructure is a complex process as pedestrian movements are affected by a variety of parameters. The present research aims at the investigation of the pedestrians' perception regarding the parameters which are considered significant for an effective pedestrian network. Towards this purpose, a comprehensive analysis of the walking conditions in a Greek medium-sized city was conducted through an extensive questionnaire survey (including a sample of over 1000 valid questionnaires) on selected sidewalks and walkways in the city center of Larissa, Greece.

The minimization of negative externalities and the achievement of the three main goals of sustainable development, i.e. social, economic and environmental sustaina-bility, are essential elements for the successful regeneration of the urban environment. The regeneration of the area surrounding the Agia Sofia axis, which is located in the historical center of the city of Thessaloniki, was the objective of a recent national architectural competition. The present paper aims to assess the environmental impacts from the application of a proposal awarded with the competition's 2nd prize through a 'before and after' study. In specific air, emissions were assessed based on the area's traffic features using the COPERT 4 model for the periods "before and after" the proposed regeneration scheme. This application led to the evaluation of the changes in the environmental conditions due to the traffic rearrangement of the study area's road network on the wider catchment area. Source
