Land Use/Cover Change and Urban Sustainability in a Medium-sized City
by Kayode Samuel, Remilekun Atobatele
Abstract: This study examined the trend in urban growth and vegetation loss and the implication of this on the sustainability of medium-size cities, using Osogbo, south-west Nigeria as a case. Using multi-temporal LandsatTM images that span 30 years (1986 to 2016), the study employed supervised classification to categorize the land cover into the built-up area, vegetation and water bodies. Findings revealed that the city grew axially along major transportation corridors in the early stage but experienced in-filling, densification and radial outward growth subsequently. The built-up areas increased at annual rate of 14.6%, more than the population growth rate of 2.6% while vegetation cover and water bodies recorded an annual change of -2.5% and -3.5% respectively. Rapid city growth and the resultant land use/cover conversion contribute to the depletion of wetlands and vegetation, thereby constituting a threat to sustainable urban development. Controlled urbanization is suggested as a panacea to the unsustainable urban expansion which threatens the citys ecological equilibrium.

Building Form Regulation Visualization in Japan: Automatic Building Volume Legality Verification via Procedural Modeling
by Hangyu Chen, Zhenjiang Shen
Abstract: Building Standard Law (BSL, 建築基準法) in Japan serves to establish minimum standards relating to the site, structure, facility, and function of buildings which protect the life, health, and property of citizens. The Building Form Regulation (BFR, 建築形態規制) in BSL controls the building volume according to the zone restrictions contained within a district plan. BFR deregulation (緩和規制) based on BSL permits certain stricter limits to be relaxed if the land conditions of the lot meet the relevant requirements. In Japan, one of the Building Permission (BP, 建築許可) procedures involves determining whether the architectural design, especially building volume, is legal or not according to BFR. This paper proposes a 3D BFR visualization which allows for efficient legality verification under BP. We utilize CityEngine, a procedural modeling code Computer Generated Architecture (CGA) in 3DGIS software. We establish shape parameters to transform BFR into a 3D shape reflective of certain land conditions which affect the 3D attributes in CityEngine. We then utilize the 3D BFR shape visualization to validate the building volume legality automatically in Python Script. We hope that the results presented here provide workable information regarding BFR and improve the efficiency of the BP procedure. In the long term, the proposed method may assist in visualizations for other urban planning regulation and data construction. Regulations may be combined with other important city data, so our results also may be meaningful for the future development of smart cities.

Recent development of Smart City in Japan
by Zhejing Cao
Abstract: The energy shortage and urge for carbon emission decrease have precipitated Japan government to carry out Smart City project more on Smart Community level. In reference to global context of Smart City from both theoretical and practical perspectives, Japan presents certain characteristics with its own uniqueness. Smart City in Japan is more promoted by enterprise and government, while less discussed in academia. This paper aims to differentiate Japans Smart City from United States and Europe to define its scope through literature reviews and comparative analysis; to formulates a comprehensive analysis framework from Smart City policy, standards, to projects, based on evidences from governmental propagandas and enterprise initiatives; and to give a hint on future Smart City development in Japan within global context. It is found that although energy efficiency is underlined for Smart City in U.S., Europe, and Japan, Smart City in Japan is also deployed on community and household level for life quality and user respect, and converted as a prototype for overseas export. The national government is the leading agent for strategic development and subsidy management, while the local government usually organizes the consortium for enterprises and various stakeholders. There are three goals and five approaches for Japan Smart City strategies with ICT (information communication technology) as the hard core. Two waves of Smart City projects have been initiated by national government, while private sectors and local government have started many other projects as supplement. For the first-wave of Smart City projects either launched for economic sectors or deployed in different geographically-determined districts, it is typically focused on smart infrastructure, energy saving and management, smart transportation, and ICT application. Stakeholder engagement, alignment of Smart City projects to strategic urban agendas, social value more than just technology orientation, and data security should also be considered, when Smart City in Japan is in a future of evolving towards disaster resilience and tourism activation, seeking global expansion, and establishing the international standards.

How to improve the interaction between cyclists and truck drivers
by Birgitta Thorslund, Katja Kircher
Abstract: The aim of this focus group study was to increase the understanding of user needs of truck drivers and cyclists with respect to future warning systems designed to decrease incidents and accidents between these groups.rnTo evaluate and describe the attitudes and behavior of bicyclists and truck drivers in urban areas, as well as their suggestions about future warning systems for these road user groups, two focus groups were carried out at VTI in Link
Keywords: Interaction; cyclist; truck driver; traffic safety; focus group; warning system; detection.

A New Perspective of Environmental Behaviour Study: A brief introduction of Wi-Fi Indoor Positioning System
by Yuming Lin, Weixin Huang
Abstract: Environment behaviour study is fundamental to architectural and urban design. The traditional methods have difficulty in obtaining quantitative data on a large scale, which indirectly hinders the intelligent process of building environment. The newly developed Wi-Fi indoor positioning system can provide a large number of effective data to environment behaviour study. This study gives a brief introduction to the Wi-Fi positioning system and analyses the abundant information contained in its data. On this basis, this study takes an innovation incubator as an example, trying to explore human interaction in the environment with the tool of social network analysis. Finally, this study provides a simple framework for implementing smart home with positioning data. The conclusions highlight the advantages and limitation of Wi-Fi positioning system, as well as the promising prospect in the smart home.
Keywords: Wi-Fi indoor positioning system; environment behaviour study; social network analysis; smart home.
Consistent Context Aware Behaviour in Smart Home Environment
by Rajarajeswari S, Neelanarayanan V
Abstract: The Home automation plays an important role in modern lifestyle because of its access in using at different places with high quality which will intern save time by decreasing human work automatically. Home automation controls the electronic devices remotely and automatically. This automatic behaviour is designed with the help of context aware behaviour Context awareness plays an important role in Smart home environment where data from various sensors and input from user or user action must be interpreted and corresponding commands to actuators must be generated. The realization of the smart home requires the seamless integration among humans, physical objects, and user interactions. Context-aware adaptation and decision support in home environments satisfies the user expectation in smart environment. This context aware automation and decision support process is done with the help of adaptive rules which is defined for the automatic behaviour of devices in the smart home environment. The consistent behaviour of the devices in the smart environment will capture the customer satisfaction. This work describes the process of checking the consistent behaviour of the context aware system in smart home environment using formal modelling and verification method. We have discussed a smart environment with its automated adaptive mechanism and checking the consistent behaviour of the adaptive mechanism. The result ensures the consistent behaviour of the context aware system in the smart environment.
