An urban planning tool demonstrator with auralisation and visualisation of the sound environment
- 2020
-
Ingår i: Proceedings of the FA2020 Conference. ; , s. 869-871
-
Konferensbidrag (refereegranskat)abstract
- The paper presents findings from a recent project about the development of a demonstrator of an urban planning tool that includes auralised sounds as well as visualisations of sound propagation and facade noise levels linked to health impact. In urban development projects, the sound environment is one of the key elements, but often enters late in the planning process. As a result, even if the noise regulations are fulfilled, the potentially good sound environment may suffer unnecessary quality reductions. In addition, the standard ways of presenting and analysing the situations, using noise levels and noise maps, has potential for improvement, especially considering the transdisciplinary approaches to planning that are increasing in use. The tool aims to simplify the usage also at early stage planning, including scenario analysis, as well as to facilitate the urban planners' understanding of the sound environment and its effects. The paper presents results from the development of the demonstrator, reflecting on auralisation as well as on multiple aspects of visualisation including grid noise maps, health-related facade noise levels and choice of colour scales.

Konferensbidrag (refereegranskat)abstract
- Digital tools are being developed for involving stakeholders in urban planning and transformation processes. One challenge is how to visualize and act upon all parameters that are relevant for dealing with complex plan-ning problems, such as environmental factors. Dialogue tools involving vis-ualization can bridge the distance between planners and citizens. This paper focuses on the problem of representing invisible environmental parameters affecting the urban climate such as wind, solar radiation, air pollution and noise, in a city model. The aim of the paper is to discuss challenges for rep-resenting and communicating environmental data in city models. In this pa-per, we have accounted for literature studies; our own conceptual modelling and prototype studies in three projects; as well as a survey with 16 urban planners. We conclude with defining design criteria for dialogue tools cre-ating a comprehensible base for communication in urban transformation processes.

Visualisation of traffic noise exposure and health impact in a 3D urban environment
- 2021

Ingår i: Paper collection of the ICBEN 2021 Congress.

Konferensbidrag (refereegranskat)abstract
- It is becoming increasingly common to work with urban planning using 3D visualisation tools. In the project DemoVirPEN a research team with participation from different research fields cooperated to create a demonstration concept for visualising traffic noise and the associated health impact in a 3D graphics environment. The project included participation from the following fields; 3D modelling and mapping, traffic noise calculation, auralisation, urban planning and architecture and health impact of noise exposure. The final product of the project is summarised in a film clip that illustrates the main results by visualising and auralising traffic in different configurations from different perspectives. A few key points are visualising short time frames (single vehicle passage) versus yearly average (noise map), and impact of changes such as removing or modifying traffic flows and buildings.

In search of visualization challenges: The development and implementation of visualization tools for supporting dialogue in urban planning processes
- 2017
-
Ingår i: Environment and Planning, B: Planning and Design. - : SAGE Publications. - 0265-8135 .- 1472-3417 .- 2399-8083 .- 2399-8091. ; 44:6, s. 1012-1035

Tidskriftsartikel (refereegranskat)abstract
- Today, urban planning processes involve many stakeholders and efficient dialogue tools are needed to support communication in transdisciplinary environments. The aim of our study is to identify visualization challenges in urban planning. Based on a state of the art study and a thematic analysis of 114 articles, published in 2004–2014 and found through snowball sampling, the development and implementation of digital visualization tools for dialogue are discussed. A wide range of examples of visualization tools for dialogue has been found; either based on 2D maps, 3D environments or gaming. The initiators of the development originate from different disciplines, such as geographic information (GI) science, computer graphics, 3D modelling, Virtual Reality, interaction design and urban planning. There has been an increasing amount of usability studies during recent years. There is a tendency for the usability studies to have gone from experimental and prototype studies to more and more concern real planning processes and implementation. Studies of implemented tools in real planning processes are, however, still rare. Gaming appears more and more frequently. Challenges are related to integration of qualitative and quantitative data, representation of data as regard appropriate levels of realism and detailing, as well as the user’s experience and the appearance of the digital models. There is a need to consider how we can achieve the full potential of visualization tools, including optimal effectiveness of visualization tools and processes for dialogue as well as how they can be implemented. Organizational preparedness is necessary, including clear ownership, allocation of resources for maintenance, competence and access to tools and technology.

Perception of Colour and Space in Virtual Reality: a comparison between a real room and virtual reality models
- 2004

- Virtual Reality has great potential to become a usable design tool for the planning of light and colour in buildings. The technical development has provided us with better computer graphics and faster rendering techniques. However, the reliability and usability is delimited by lack of knowledge about how humans perceive spatial colour phenomena. The setting up of parameters for material properties in light calculation software is done arbitrarily. We present a comparison between a real room and a digital model evaluated on a desktop PC and in an Immersive Projection Technology (IPT) type system. Data were collected from video recorded interviews and questionnaires. The participants assessed the appearance of light, colours and space. They also evaluated their involvement in solving this task, and their presence in each environment. Our results highlight the benefits and disadvantages of the real and virtual models. The participants had difficulties in estimating the size of both the desktop room and the room in the ITP system. The comparison of real and virtual rooms revealed unsatisfying differences in shadowing and colour appearance. We defined the magnitude of perceived colour reflections in the real room, and elaborated with some of the parameters in Lightscape/3dsmax6.

Towards digital twinning for multi-domain simulation workflows in urban design: a case study in Gothenburg
- 2024

Tidskriftsartikel (refereegranskat)abstract
- This work proposes an automated workflow using digital twinning for multi-domain environmental performance analysis of urban developments. Digital twins can potentially provide a common basis for multi-domain simulations and help overcome data availability and interoperability issues. The proposed workflow consists of five steps: (1) creating a procedural urban 3D model, (2) generating design alternatives parametrically, (3) exporting the context and each design alternative to each simulation tool, (4) running simulations for wind comfort, energy demand, and noise for each design alternative, and (5) combining and visualizing the simulation results using the digital twin. The workflow was applied to a neighbourhood in Sweden, the resultsreveal significant reduction in manual work when applying multiple simulation software for different domains. This is one step forward in streamlining the workflow for urban analysis, crucial for multi-domain optimization. In the future, further domains and simulation tools can be added to the workflow.
