Subdivided Cellular Automata Model Considering Anticipation Floor Field and Analysis of Pedestrian Detour Behavior

The micro-pedestrian simulation model represented by the cellular automata model is an important simulation model. Improvements in various aspects enable a better description of the various behaviors of pedestrians, such as pedestrian avoidance behavior, companion behavior, as well as transcendence behavior, waiting behavior and detour behavior. This paper takes the pedestrian detour behavior in the circle antipode experiment as the main entry point. The subdivision cellular automaton model is integrated into the prediction field to model and simulate the detour behavior. At the same time, it explores the degree of subdivision of the cell. Pedestrian heterogeneity and the influence of predicted field potential energy on the simulated pedestrian trajectory. Finally, based on the temporal and spatial indicators of pedestrian trajectory characteristics, the KS test and DTW method are used to evaluate the similarity of the trajectory distribution characteristics and time series characteristics with experimental samples, and evaluate and compare models with or without heterogeneity. The results show that the trajectory characteristics of heterogeneous pedestrians are closer to the experiment than homogeneous pedestrians.

172A research-policy partnership for the achieving the Sustainable Development Goals in Bangkok

Focus of presentation Through the UN’s Sustainable Development Goals (SDGs), there is a major commitment from cities to prioritise health and wellbeing, reduce poverty, support environmental resilience, and increase liveability. Existing tools for tracking progress towards liveable, equitable cities have been developed primarily for high-income country contexts. This project is a collaboration led by RMIT University (Australia), partnering with the Bangkok Metropolitan Administration (BMA) (Thailand), the UN Global Compact - Cities Programme, and the Victorian Department of Health and Human Services (Australia). It aims to provide a proof-of-concept spatial indicators system using open access and local spatial data to monitor progress towards the SDGs in Bangkok. Findings Approximately 50 spatial indicators aligned to the SDGs have been generated for Bangkok. These are available in a range of formats, including a bi-lingual online-portal, and static and interactive maps. The BMA have identified three Bangkok districts for deeper interrogation, and on-going workshops shape the capacity building activities. Conclusions/Implications This partnership has enhanced understandings of liveability within the SDG framework including: i) providing indicators for monitoring liveability in a low-to-middle income city context; ii) developing an international liveability network and deeper understanding of challenges; and iii) creating opportunities for capacity building and reciprocal learning. Key messages There has been little ‘liveability’ guidance for cities in low- or middle-income country contexts. This project contributes to the global SDG agenda to enhance health and wellbeing through the built environment in diverse contexts.

LA REPRESENTACIÓN BIDIMENSIONAL DEL ESPACIO Y EL TIEMPO EN LAS VANGUARDIAS DEL ARTE

El espacio y el tiempo son dos conceptos fundamentales en la representación de la obra de arte, por ello, este escrito parte de la definición y estudio de los conceptos, teorías y paradigmas que se han generado al respecto y de su aplicación en el arte. Para este propósito, se hace una exploración teórica dada a partir de la filosofía, la cual sirve como base para abordar dichos conceptos desde la naturaleza, realidad y estructura métrica del espacio y del tiempo; en un segundo apartado, se analiza su configuración formal mediante aspectos como: la percepción del espacio que contempla los niveles de profundidad, el traslapo, la transparencia y las deformaciones como indicadores espaciales, gradientes y tipos de perspectivas; la representación del tiempo, en donde se contemplaron los sucesos, la simultaneidad, la secuencia, la velocidad, el movimiento estroboscópico, la dinámica y la oblicuidad; finalmente, se analizaron los tipos de espacios (cognoscitivo , abstracto, perceptivo, creado, vivencial, artístico) y tiempos (mental, físico, periódico, cronológico, vivencial) presentes en la obra. El objetivo de esta investigación consiste en determinar los elementos compositivos que hacen evidente la aparición de diferentes espacios y tiempos en la obra de arte. Se presentan como casos ejemplificativos las obras de Pablo Picasso (Las Señoritas de Avignon, 1907), Wassily Kandinsky (Composición VIII, 1923) y Piet Mondrian (Cuadro Nº 2, 1925). Los resultados de este trabajo de análisis aportan una base conceptual referida a la representación y la configuración formal del espacio-tiempo en el arte pictórico de vanguardia del siglo XX. Palabras clave: Representación, espacio-tiempo, arte, vanguardias.AbstractSpace and time are two fundamental concepts in the representation of artwork. Thus, this writing embraces the definition and study of the concepts, theories and paradigms that have been generated in this regard and their application in art. For this purpose, a theoretical exploration was made based on philosophy, which serves as a basis to address the concepts from the nature, reality and metric structure of space and time. In a second section, the formal configuration was analyzed through aspects such as: space perception, which considers depth levels, overlapping, transparency and deformations as spatial indicators, gradients and types of perspectives. The representation of time, where events, simultaneity, sequence, speed, stroboscopic movement, dynamics and obliquity were contemplated. Finally, space types (cognitive, abstract, perceptual, created, experiential, artistic) and times (mental, physical, periodic, chronological, experiential) present in the work were analyzed. The objective of this research was to determine the compositional elements that make the appearance of different spaces and times evident in artwork. The works of Pablo Picasso (The Young Ladies of Avignon, 1907), Wassily Kandinsky (Composition VIII, 1923) and Piet Mondrian (Table Nº 2, 1925) are presented as exemplary cases. The results of this analysis work provide a conceptual basis for the representation and formal configuration of space-time in avant-garde pictorial art of the 20th century.Keywords Representation, space-time, art, vanguards.

Estimating the Impact of Urban Planning Concepts on Reducing the Urban Sprawl of Ulaanbaatar City Using Certain Spatial Indicators

The urban sprawl process of Ulaanbaatar has changed dramatically due to population growth. Ulaanbaatar city land management master plan defined the settlement zone area suitable for living as 33,698 ha. However, due to unrestricted urban sprawl caused by the exponential growth of the city’s population, the settlement zone area reached 39,235 ha, which exceeds the limit by 5537 ha. In order to tackle this issue, several urban planning concepts were developed to be implemented within Ulaanbaatar city urban planning framework. It is, in any case, problematic to choose a single planning concept due to the fact that neither measurements nor analyses are being made of the respective spatial indicators in urban planning assumptions that are taking urban form into consideration. One of the prerequisites for identifying an optimal concept in urban planning is an assessment of urban form, and measuring the impacts against its spatial data. This study uses 1990–2020 satellite image data to investigate the urban form of Ulaanbaatar with a future action plan. Using remote sensing and GIS technology, Ulaanbaatar city sprawl was analyzed for defining urban form, and consequent results were obtained by comparatively measuring the impacts of monocentric, polycentric, and compact city concepts on city sprawl by applying spatial indicators that have been used in the world’s major cities. The study results show that the compact city concept is the optimal solution to reduce uncontrolled city sprawl based on a technical point of view. This will lower Ulaanbaatar’s sprawl threefold and compress the urban settlement area down from 39,235 ha to 12,479 ha.

Exploring Effective Sensory Experience in the Environmental Design of Sustainable Cafés

The aim of this study was to explore and construct spatial indicators suitable for green café ambience. The indicators were further empirically verified. A three-round questionnaire survey, based on the Delphi method, was conducted with 15 experts, including university professors (food and beverage services management and interior environmental design), café operators, and personnel from government agencies. Data were collected, and the results on the characteristics of the repeated feedback from the experts were convergent. Thirty-six indicators suitable for the design of green café ambience were extracted, of which 17 were verified by actual cafés as highly operable. The five-sense indicators of sustainable green ambience design obtained in this study can facilitate positive customer experiences and enhance the appeal of maintaining sustainable green trends for cafés. These indicators can also provide references for café operators in business planning and green café ambience design.
