Ville souterraine

Résumé

Une ville souterraine est un ensemble d'édifices et de constructions souterraines urbaines reliés entre eux par un réseau de tunnels ou accessibles depuis la surface. Généralités thumb|Vue d'une partie de la ville souterraine de Montréal : hall de la station de métro Bonaventure. Une ville souterraine existe habituellement dans la partie la plus dense d'une ville, c'est-à-dire généralement dans son centre-ville. Elle peut inclure des bureaux, des centres commerciaux, des stations de train ou de métro, des cinémas ou tout autre aménagement situé sous le niveau de la rue. Ces zones sont reliées par des tunnels. L'accès à une ville souterraine peut être réalisé par l'intermédiaire des espaces publics des bâtiments qui la composent ; elle peut également posséder ses propres accès. Les réseaux souterrains sont importants sous les climats froids ou très chauds, leurs constructions autorisant un accès aisé tout au long de l'année, quelle que soit la température. Le concept des

The multimodal walker. Potentials for combining walking and public transport at the agglomeration scale.

Sonia Lavadinho

Recently major transport operators such as Transport for London or RATP in Paris developed an interest for walking issues, and seek to promote walking as an integrated part of their transport offer. This paper draws from two case studies being carried out on behalf of these operators. It will explain in which context this interest has risen, what are the motivations behind the development of a walking-friendly network (focusing on its hubs, their attractiveness and accessibility as well as their relations to other attractors), and how targeting the walker as a potential client for public transport can be achieved. The paper will show how walking and public transport enhance each other as they enrich the realm of possibilities regarding both mode choice strategies and route strategies. It will also explore walkings pivotal role in associating public transport with individual modes of transport. Walking performance is decrypted as a vital factor in developing full-fledged multimodal trip-chaining capacities, especially when linked with on-demand modes of immediate and free access, such as vélib and autolib. A typology of walking facilitators and hindrances will be brought forth to describe both optimal and suboptimal conditions within the exchange nodes and interfaces themselves as well as beyond into the public realm. This paper will also describe the advantages and the shortcomings of a certain number of design principles aimed at promoting walking, for instances active frontage that facilitates navigation, pedestrian interfaces that fulfil pedestrian-specific needs, and the weaving of over & underground spaces into a continuous walkscape. Finally, this paper shall deal with the crucial notion of which are the optimal scales to develop an operating walking network in order for walking to be truly efficient, not just by itself but especially in combination with other modes. The paper outlines the idea that the multimodal walker is at its best at the agglomeration scale, and goes on to give some groundbreaking arguments on why this is so.

Four underground resources have been seen as having a long-term potential to support sustainable urban development: underground space, groundwater, geomaterials and geothermal energy. Utilization of these resources proposes a new paradigm of economic development: underground urbanism. The new management approach named “Deep City Method” is put forward to aid decision-makers to integrate global potential of the urban underground into city-scale strategic planning. The research output will be presented in form of two papers each with a different focus. Part 1 aims to introduce the concept, process and initial application in Switzerland; Part 2 is devoted to show methodological insight for a new zoning policy in China and investment scenarios for project cost viability. This Part 1 paper will begin by presenting the fundamental concept of the Deep City Method, followed by a proposition for a trans-institutional planning process. The application is firstly based on a rating system to identify cities having a potential for underground development. The city of Geneva is selected for conceptual application and strategic level study. Further operational steps are required in order to generalize the concept to other cities around the world.
