Spatial Dynamics, Networks and Modelling

Edited by Aura Reggiani and Peter Nijkamp

This important new book provides a valuable set of studies on spatial dynamics, emerging networks and modelling efforts. It employs interdisciplinary concepts alongside innovative trajectories to highlight recent advances in analysing and modelling the spatial economy, transport networks, industrial dynamics and regional systems. It is argued that modelling network processes at different spatial scales provides critical information for the design of plans and policies. Furthermore, a key issue in the current complex and heterogeneous landscape is the adoption and validation of new approaches, models and methodologies, which are able to grasp the emergent aspects of economic uncertainty and discontinuity, as well as overcome the current difficulties of carrying out appropriate forecasts. In exploring diverse pathways for theoretical, methodological and empirical analysis, this exciting volume offers promising and evolutionary perspectives on the modern spatial network society.

Chapter 17: An ex ante Evaluation of an Urban Project through Property Value Increases: A Hedonic Price Approach

Roberto Camagni and Roberta Capello


Roberto Camagni and Roberta Capello 17.1 INTRODUCTION This chapter focuses on the economic assessment of a relevant urban infrastructure project using expected increases in land values as indicators of the potential benefits to the urban population. The project concerns the laying underground of part of the urban rail track in the city of Trento, situated in the Alps, in northeastern Italy, along the Brenner Corridor Verona–Innsbruck–Munich. In fact, the rail track represents a barrier inside the city in a North–South direction, generating a low-accessibility, low-quality urban land belt running between the rail track itself and a second North–South barrier represented by the river Adige (Figure 17.1). The recent land-use plan of the city, produced under the direction of the Catalan planner Joan Busquets, recommends laying the central part of the rail line underground, for a length of 2 km, in order to reunite the two parts of the city, create improved accessibility to the city centre (which developed in an eastward semicircle around the central station) and new urban amenities – a boulevard replacing the rails, new high-quality buildings and recreation facilities. The policy question regards the economic viability of the project in terms of cost–benefit balance for the local community, given the huge public investment requested. This chapter proposes an assessment of the general social benefits through the evaluation of the expected increase in land and real estate values. In fact, all the potential advantages of the project refer to elements that have a direct...
