Symposium on “Smart City Development: Planning and Design”

Theme: The city-technology link has recently attracted much academic and policy attention, as evidenced by burgeoning smart city visions, scholarly debates, and normative policies in different parts of the world. While advanced information and communications technologies have transformed many aspects of cities and urban life, the emergence of new science and analytics has provided new approaches to studying, planning, developing, and managing cities.  This symposium will present DUPAD’s latest research on some of these issues and a new Master of Science in Urban Analytics developed to meet growing demands and equip urban professionals with cutting-edge analytics and smart planning and design skills.

Title
Matthew Effect in Mega City Metro – Shanghai and Paris: Inverting the Matthew Effect by Network Design

Abstract
By 2035 Paris mega city concerted effort is to create a new city, invoking specific policy initiatives and institutions: a new mass transportation network (the Grand Paris Express – GPE) doubling its current length, a proposed regional administrative body, new targets for housing and plans for city greening — more than a single redevelopment plan, Grand Paris is a new political vision for Paris and a proposition for a new paradigm for urbanism. The GPE redistributes and network the equity of public transport accessibility to suburban centralities.In comparison of the Shanghai’s urban rail network has grown to be the largest urban rail network in the world. Shanghai metro follows a typical development schema: the urban core develops cumulative advantage: the paradoxical combination of decentralisation and simultaneous re-centralisation of the urban core due to structural accessibility/flow potential growth rate differential. Dubbed “no winner takes all”; while it seems that accessibility growth is shared by every station, in relative terms, ‘the Matthew effect’ of accumulated advantage happens: the most endowed stations, the urban core, gets more, and the least (peripheral stations) gets less, spatial inequity in access increase. We demonstrate how such a trend can be mitigated by network design. Urban planning and design analytical research should give much more attention to strategic urban design counterfactual simulation.

Bio
Mr Alain Chiaradia is Associate Professor at the Department of Urban Planning and Design, Faculty of Architecture, The University of Hong Kong (HKU). He is the Programme Director of the Master of Urban Design.

His research interests are urban morphometrics, i.e. the creation and operationalization of design measurements to evaluate impacts and values of strategic urban design and urban design. Innovative 3D morphometrics based on network science that embed human spatial navigation cognition features enable the differentiation of complex urban form properties emerging in large and dense conurbations in the USA, UK, France and China allowing investigation of their relation to economic, social and environmental impacts.

Mr Chiaradia leads the conceptual development of spatial design network analysis software (sDNA). sDNA provided standard morphometrics for the largest biological resource in the UK. In the last five years he has focused on high density city and urban system (Yangtze River Delta, Shanghai and Hong Kong).

Mr Chiaradia was previously Executive and Board Director at the global consultancy Space Syntax Ltd. where he directed large-scale projects concerning spatial policy analysis, urban design policy formulation and evidence-based spatial design policies in major cities including Paris, London, Boston and Shanghai. He has and continue to advise leading international urban design practices and city authorities. He was Senior Research Fellow at University College London. In the UK, he has been member of impactful research project advisory panels at national level. Currently he is on the advisory scientific committee of Efficacity.

Title
Data Empower Planners: Linking Research and Practices in Hong Kong

Abstract
Emerging smart technologies of the digital age such as smart sensors, simulation and machine learning provide new opportunities for planners to tackle cities of growing complexity. Data can be used to empower professional practitioners in better understanding of city dynamics, informing planning processes, enhancing development proposals, as well as testing and calibrating prevailing theories. Examples are drawn from research projects undertaken by the Sustainable High Density Cities Lab of the HKUrban Labs from The University of Hong Kong, in which academic researchers and practitioners work together in order to improve urban environment performances and quality of lives. Early-stage actions, forward-looking partnership, and human-centric values are the keys.

Bio
Jianxiang Huang is Assistant Professor in the Department of Urban Planning and Design, Faculty of Architecture, HKU. He is a Visiting Professor at Gdansk University of Technology (GUT) funded by the Erasmus Programme. He is the Co-Director for the Sustainable High Density Cities Lab, an interdisciplinary research centres across disciplines of Engineering, Medicine, and Architecture, in which he leads research projects on urban heat, noise, air pollution and building energy performances using numerical modelling and geo-tagged data analytics. He develops numerical models and licenced software to assist design decisions in urban heat island mitigation, building energy efficiency, traffic noise mitigation, and enhance of occupant thermal comfort. CityComfort+ has been applied in redevelopment projects by the Hong Kong Urban Renewal Authority.

Dr Huang teaches lecture-based courses on urban theories, technologies, and design studios in Hong Kong and overseas context. He is the thesis coordinator and admission tutor for the Master of Urban Design Programme, to which served as the Assistant Programme Director between 2013 to 2016. Prior to joining HKU, Jianxiang was an urban designer at Sasaki Associates Inc. from 2007 to 2010. He worked on projects that received awards from the Society of College and University Planning (SCUP), International Downtown Association (IDA), the American Institute of Architects (AIA), and the Boston Society of Architects (BSA). He is a LEED accredited professional, a member of the American Institute of Certified Planners (AICP), and a former member of the board of directors of the International Association for China Planning (IACP). Dr Huang holds a Doctor of Design from Harvard University, a Master in City Planning from MIT, a M. Arch and a B. Arch from Tsinghua University.

Title
Connecting the City: A Three-dimensional Pedestrian Network of Hong Kong ​

Abstract
The purpose of the research is to investigate how a three-dimensional (3D) pedestrian network reshapes connectivity and helps to integrate the built environment of high-density cities. Using the case of Hong Kong, first, we elaborate how a continuous 3D network constitutes an entirely different urban morphological spatial hierarchy compared to two-dimensional because of the footbridge system, underground connected with metro stations, and paths connected with mall developments. Second, we construct a 3D pedestrian network model classifying segments into 23 categories with multi-height levels (e.g. sidewalk, footbridge, underground, crosswalk, ramp, paths on the building roof). Then we map the first 3D city-wide pedestrian network for Hong Kong territory in a geographic information system. Since road networks are widely used as a proxy for pedestrian analysis, we suggest that active travel optimisation planning, especially in high-density cities, requires a bespoke 3D pedestrian model.We have transferred the value-added pedestrian network to Lands Department of Hong Kong SAR. The data becomes a crucial part of the spatial infrastructure of Hong Kong, and will be open to society for free use to stimulate walkability research and smart city innovations. The 3D pedestrian network is a fundamental consideration in urban planning and design practices for high-density cities, and will encourage a paradigm shift in walkability and built environment studies.

Bio
Dr Guibo Sun is Assistant Professor in the Department of Urban Planning and Design, Faculty of Architecture, HKU.  He was the winner of Royal Town Planning Institute (RTPI) Early Career Academic Award in 2019, commending his project of mapping the three-dimensional pedestrian network of Hong Kong. His research focuses on urban interventions in built environment and impacts on active transport. He is Principal Investigator or Co-Investigator of several GRF and NSFC research grants, and conducting research in Hong Kong, Greater Bay Area and Belt and Road countries, and has published actively in urban studies, transport and health related journals.
