However, urban designers are particularly reluctant to become digital and use software that automatically generates cities. Instead, they return to traditional design skills such as creating scale models, sketching, notations and drafting. There is an increasing advocacy for design to a human scale, placemaking and liveable cities. This viewpoint asks questions about the application of AI and generative algorithms in digitizing urban design practices. It reflects on the possibilities of conjoining urban morphology and design theory into City Information Modelling (CIM) as a new digital tool for urban designers and reveals challenges in the ongoing development of new CIM software. Urban designers work within intricate design worlds with toolboxes that consist of customized design elements and symbologies. The design worlds consist of elements, rules and patterns and they act as holding environments for their unique diagrammatic design knowledge. CIM and AI should understand design worlds with customized toolboxes and provide help to automate repetitive behaviour patterns while designing.

Swedish public agencies have promoted lowering parking requirements to decrease automobile travel, oil consumption and carbon emissions. However, the implementation of restrictive parking policies lacks discussions about the role of the built environment and accessibility. If low parking standards are introduced in developments where it is impossible to walk, cycle or use public transportation, they do not work. This paper proposes a conceptual framework that links parking with the research on the effect of built environment on travel. It describes a model to calculate flexible parking standards based on built environment and accessibility factors commonly used in urban design and planning practices. Transportation systems need environmental preconditions. Parking requirements and expressways support driving around. Research shows that integrating walking, cycling and public transportation need complex sets of fa...

We are in a midst of a new revolution in machine learning with ‘neural nets’ capable of understanding human speech and written language and analysing content on images and videos. The neural nets can semantically parse scenes on images recognizing objects, creating scene graphs, and describing content with text. However, specialized neural nets for urban morphology do not exist. Neural nets can recognise artefacts from specific historical ages or learn about architectural styles only if they are supervised by experts. To create urban morphological architectural intelligence that can help with morphological research or morphologically-informed urban design practices, urban morphologists need to translate their analytics and practices into software specifications. Creating specialized neural nets for urban morphology requires expertise in software engineering and programming effo...

To achieve sustainablemobility in the cities, it is necessary to improve energy efficiency and lower carbonemissions through the promotion of walking, cycling and especially public transportation.The urban form is a great obstacle in achieving sustainable mobility. Many Swedishcities were designed for the private automobile and they lack possibilities to walk, cycle anduse public transportation. To address this problem, this project developed and testedUrban Mobility Certificates (UMCs) or transportdeklaration in Swedish. The UMCsvisually inform sustainable mobility as integration with walking, cycling and publictransportation, estimate modal shares, transportation energy use in kWh/year/person andcarbon emission in t CO2/year/person. Visualizing this information has a potential totrigger a virtuous cycle of transforming neighborhoods, catalyzing sustainabledevelopment to better integrate walking, cycling and public transportation in Swedishneighborhoods.The UMCs produce reasonable results with acceptable errors that are common for thiskind of trip generation models. The can be used to identify unsustainable mobility inexisting neighborhoods and new developments. The UMCs directly inform sustainablemobility in a very concise form (integration, modal shares, transportation energy use inkWh/year/person and carbon emission in t CO2/year/person) and show a complex set ofurban form and accessibility factors as background for the modal shares forecasts. Bothconcise and complex information is needed to illuminate the complex link between urbanform and sustainable mobility. In addition, the methodology can be used to analyzealternative scenarios to redesign sprawling Swedish neighborhoods into more sustainableurban forms. Scenarios like mixed development, introduction of public transportation orcreating a network of walkable streets (called promenadstad in Swedish) can decreasetransportation energy use by 1000 kWh/year/person to 3000 kWh/year/person(extensions of historical urban centers) or halve the Swedish average of 6000kWh/year/person. It is very important to use the UMCs in the earliest stage of the urbanplanning and development process.Sustainable mobility is possible only if there are choices to walk, cycle and use publictransportation. To help in redesigning and redeveloping the Swedish neighborhoods thatare oriented to the automobile, this project furthermore presented a model of small andlarge Swedish city with typical neighborhoods. The application of the UMCs in Swedishplanning and development processes must be understood as a process of informing aboutlack of mobility choices and urban interventions such as introduction of walkable streets,cycling and public transportation infrastructures, mix of functions and Transit OrientedDevelopment (TOD) in typical Swedish neighborhoods

To make this possible there is a need to provide information about possibilities to use different modes of transportation in cities and energy use from transportation in buildings. This paper proposes, describes, tests and discusses a model to estimate modal shares of different transportation modes (walking, cycling, public transportation and private automobile) and calculate energy use from transportation based only urban form and accessibility factors. The aim is to visually inform actors and stakeholders such as real property developers, municipalities, public authorities, etc. about how well different buildings are integrated with walking, cycling, public transportation and private car, potential energy use and environmental impacts.

There is a kaleidoscope of urban definitions and standpoints, but there are no tools that capture the variegated viewpoints and representations in urbanism. In this article I look at different urban theories, discourses and representations in architecture, sociology, geography, economy, transportation, computer science in order to conceptualize city information modeling (CIM). CIM is conceived and discussed as a system of blocks with dynamic relations or connections that define and redefine territories. The urban life today is a sequence of temporally inhabited and interconnected spaces, movable or fixed. The connections between spaces inspire or inhibit contacts and interactions between people. They bend times and continuously shape and reshape spaces, sociabilities and situations. In architecture there was an evolution from computer-aided design (CAD) to building information modeling (BIM), but in urbanism, where the geographic inf...

In a broader perspective, TOD deals with synchronizing urban life---its growth and development, its everyday activities and mobility patterns---with public transportation systems. Urban development is a product of negotiation, a political struggle between actors and stakeholders, their visions and interests, and their powers to induce urban change. In the background of urban politics, social and physical factors limit the potential to develop or transform. In this study, this potential for urban development and transformation is analyzed for three neighborhoods along the Tunnelbana, a subway line in Stockholm, with the help of geographic information systems (GIS) software. Two development scenarios are explored: one with TOD applied, the other with it dominating as a policy.
