City Rhythm: logbook of an exploration

Rhythm is fundamental to life. Rhythm can be perceived in the movement of the sun, the moon and the stars. Rhythm makes our hearts tick and defines our breath, in and out. And even the smallest particle in a microbe is part of rhythmic movements. Rhythm in activities is important for culture, for religion, and for sports, schools and hospitals...

Haagse Hitte: Het Haagse warmte-eiland in kaart gebracht

De afgelopen jaren zijn verschillende studies verricht naar het warmte-eiland effect in Nederland. Een studie van TNO (TNO, 2012) heeft voor wat betreft Den Haag de toon gezet. Den Haag zou van alle Nederlandse steden het sterkste warmte-eiland effect kennen. Die beeldvorming heeft gezorgd voor een maatschappelijke en politieke bezorgdheid die...

Updated Urban Facade Design

The increasing migration into cities leads to an increasing number of people stressed by noise. More and more people are moving into urban settings comprised of multiple noise sources and hard reflective glass and steel facades. The omnidirectional arrangement of noise sources like airborne noise or car traffic noise and their reflection on the...

Automated large scale parameter extraction of road-side trees sampled by a laser mobile mapping system

In urbanized Western Europe trees are considered an important component of the built-up environment. This also means that there is an increasing demand for tree inventories. Laser mobile mapping systems provide an efficient and accurate way to sample the 3D road surrounding including notable roadside trees. Indeed, at, say, 50 km/h such systems...

A data model for operational and situational information in emergency response: The Dutch case

During emergency response a lot of dynamic information is created and needs to be studied and analysed in the decision-making process. However, this analysis of data is difficult and often not possible. A major reason for this is that a lot of information coming from the field operations is not archived in a structured way. This paper presents a...

Automatic object recognition and change detection of urban trees

Monitoring of tree objects is relevant in many current policy issues and relate to the quality of the public space, municipal urban green management, management fees for green areas or Kyoto protocol reporting and all have one thing in common: the need for an up to date tree database. This study, part of the Tree and Image research project,...

Enabling obstacle avoidance for Google maps' navigation service

City infrastructures are sensitive to disasters. To aid rescue workers and citizens, a system is needed which determines the shortest route to a certain location, taking the damages of the infrastructure into account. The biggest disadvantage of current navigation systems is that they are “closed” i.e. they are built on top of commercial...

The Power of Ten: The KaDEr Project and the Influence of Education in Real Cases

The KaDEr research project is looking for possible changes in the policy to preserve built heritage in a sustainable way for the province of Gelderland. From 2017 to 2021, TU Delft conducts this research project. A lot of disciplines of TU Delft are involved from the Faculty of Architecture. The Heritage & Architecture (HA) is in the lead....

Developing a Framework for Qualitative Evaluation of Urban Interventions in Iranian Historical Cores

Iranian historic city cores are important parts of modern cities because of their valuable monuments and morphology but are also significant because of their population density, location and the major governmental functions they house. Since 1920, modernisation policies and urban development trends in Iran have justified spatial transformation...

Progettazione Struttural e Funzione Sociale dello Spazio quale vulnerabilita e soluzione al terrorismo urbano

This article presents the knowledge gaps and the methodological steps inherent the process of standardization of the terrorist threat in urban environments for the structural design and rehabilitation of buildings for civilian use. The necessity for a revision of the current technical codes for building constructions which shall include also the...

An Analysis of the Emerging “Shared Mobility Hub” Concept in European Cities: Definition and a Proposed Typology

Seamless, efficient transport intermodality is a key aspect of the transition of cities toward sustainable mobility. The new “shared mobility hub” concept is increasingly gaining attention as a potential way to make this urgently needed transition happen. The present paper aims to provide an insightful view of the promising concept of shared...

Urban, suburban or rural? Understanding preferences for the residential environment

There are two ongoing trends that lead to changing preferences for the built environment. One concerns a demographic transition into more but smaller, and older, households. The other concerns greater possibilities to satisfy residential preferences due to rising incomes and technological advances. The current study explores the preference...

The resurgence of regional design

Regional design, long a backbone for spatial planning, even if under other names, has become topical again for two reasons – as a key strategy and as a key tool in spatial management. This is due to several reasons. New conditions of urbanization that result from the convergence of several factors highlight the need for spatial strategy...

Research Programme 2009 - 2014: OTB Research Institute for Housing, Urban and Mobility Studies

The OTB’s research covers the areas of housing, urban, mobility and geo-studies. The research activities deal with the built environment, and refer to aspects of the technological sciences, the policy and management sciences, the behavioural sciences, spatial disciplines and the application of information and communications technology. This...

Subsurface Equilibrium: Transformation towards synergy in construction of urban systems

By jointly approaching the challenges we face – such as ongoing urbanization, climate change, energy transition and the introduction of new mobility such as automated and electric vehicles – urban areas can be made more resilient. The<br/>subsurface of the city can play a central role in this, for instance by using space made available by a...
