    COVID-19 has been spreading worldwide since 2020. Although the World Health Organization recommends maintaining a physical distance of at least 1 m among people, the Japanese government recommends 2 m. In this study, we used deep learning and other techniques to statistically compare and verify the change in the physical distance between pedestrians on a sidewalk in a large Japanese city before and after the COVID-19 pandemic. A video-based approach was used to accomplish this. The video before the COVID-19 pandemic was recorded in October 2018 in the Namba area of Midosuji, Osaka City. For comparison, new videos were recorded at the same location in October 2020. YOLOv3 SPP was applied to automatically extract a large number of pedestrians on the street. Three observation areas were set on the sidewalk within the target area, and the physical distances between the pedestrians were measured. Two indices were used to measure the physical distance: the average nearest neighbor and Ripley’s K-function. Thus, the change in the physical distance between people on the street, before and after the COVID-19 pandemic, could be quantitatively and statistically compared. The results showed an increase in physical distance after the COVID-19 pandemic, which depended on the state of behavior, density, and human relations.

    <p>As for the safety of bicycle traffic environment, it is desirable for bicycles to travel in the same direction as automobiles on the roadway because it is considered that the difficulty for car drives to recognize bicycles outside the roadway is a cause of accidents, and the development of a travel space based on traffic on the roadway is being promoted. In this study, video surveys were conducted at several signalized intersections with different intersection inflow conditions for bicycles and left-turning vehicles, and trajectory data from the faster Regions with Convolutional Neural Network Method (Faster R-CNN) was used to investigate the complex phenomenon of straight-line bicycles and left-turning vehicles. For the evaluation method, we focused on the change in speed during the time of conflict and used the quasi time-to-collision (TTC) and the speed difference through the intersection. As a result, it was found that while the speed of bicycles did not change much between different sections of the road, the presence or absence of complications and the position of the traffic were major factors in determining the speed.</p>

    <jats:p>This study aims to clarify the impact of the COVID-19 pandemic on home range. The home range is the area that individuals traverse in conducting their daily activities, such as working and shopping. In Japan, the central government declared the first state of emergency in April 2020. This study analyzed the panel data for mobile phone GPS location history from April 2019 to April 2020 in Ibaraki City, Osaka Metropolitan area. The study applied the minimum convex polygon method to analyze the data. The results show that the home range decreased significantly between April 2019 and April 2020. Specifically, the home range in 2020 decreased to approximately 50% of that in 2019 because of COVID-19 infection control measures, preventing people from traveling far from their homes and only allowing them to step outside for the bare minimum of daily activities and necessities. The results suggest that the emergency reduced people’s home ranges to the neighborhood scale. Therefore, it is necessary to consider designing new walkable neighborhood environments after the COVID-19 pandemic era.</jats:p>

     Since office buildings vary in location, size, facility, rent and so on, it is difficult to illustrate their market with the average of such indices; segmentation according to those building specifications (specs) is needed. As an example of segmentation, some real estate-related companies grade office buildings according to their specs. Although their standards differ from each other, a few companies use the height and age of buildings. Conversely, attributes such as location, gross floor area, base floor area and building age are commonly used even though their values still differ for each company. Moreover, the number of grades differs from company to company, with there being two to four grades. These standards of grades have monotonicity, with wider floor area, newer buildings, etc. being better. In foreign countries, real estate-related companies also grade office buildings and make market reports on the basis of the grade. For example, Building Owners Management Association, which is an organization of office building owners in the United States, sets three grades of buildings, as A, B and C, in descending order and defines the overall characteristics of each grade. This grade differs from that of Japan in that rent is considered to be one of the building specs. Standards of the office building grade evaluation are subjective, sensory, and differ from company to company in that one company might deem a building to be A grade and the other might deem the same building to be B grade.<br> With the above discussion as the backdrop, we propose a quantitative grading method for office buildings. This method optimizes the thresholds of each spec of office buildings so as to maximize the variance ratio of contracted rents of targeted office buildings for each grade. We formulate this problem as parametric mixed integer programming and validate the method with the data of office buildings located in 23 Tokyo wards in 2013 and 2014. In the experiments, we tested 11 combinations of building specs.<br> The results of the experiments support the following conclusions. Compared with the existing typical office building grades published by some companies, the proposed method can grade office buildings that exhibit an increased variance ratio of rent. The best combination of building spaces derived by the proposed method comprises the following specifications: a location that is within the main five wards, building age, total floor area, base floor area and ceiling height. These specs differ slightly from those of the existing standards. The existing standards tend to classify buildings that have rents close to the average of different grades; overlaps of rents between different grades are often seen. Conversely, the proposed method sets the grade to classify buildings that have high rents in different grades.<br> Since the term of the data used for this experiment is only 2 years, we need longer-term data to validate the stability of the derived building specs. In addition, since we limited the combination of attributes to 11 due to the constraint of computational time, we should examine the combination of attributes exhaustively.

    A panel-hinge framework is a structure composed of rigid panels connected by hinges. It was recently proved that at a generic position, the rigidity of panel-hinge frameworks can be predicted by examining a certain combinatorial property of the underlying graph. In this study, we apply such combinatorial characteristics to create design forms. When considering the application of design forms, we must also take into account non-generic cases. In this paper we develop two new approaches
    the first one that the method inductively generates non-generic rigid panel-hinge frameworks consisting of orthogonal panels and the second one that inductively generates non-generic rigid panel-hinge frameworks based on fractal geometry coupled with space-filling convex polyhedron as a construction unit. We will give examples of forms created by the proposed method in order to demonstrate the applicability of the proposed methods to design forms.

    This paper presents novel algorithms for enumerating architectural floor plans. The enumeration approach attempts to generate all feasible solutions that satisfy given constraints. Therefore, such a method might usefully reveal the potential diversity of Open Building floor plans. However, combinatorial enumeration solutions easily explode even for small problem sizes. We represent a space by a set of cells and organize some cells into polyomino-like configurations. We then enumerate all cell combinations that can be tiled in the given space using an efficient search algorithm for combinatorial problems. We also propose queries for extracting specific floor plans that satisfy additional constraints from all enumerated floor plans without re-enumeration. Our approach solves a 56-cell configuration space within a realistic timeframe.

    We analyze the energy consumption data of tenants in office buildings in Tokyo and show that it is able to estimate the specific energy consumption of each tenant with a high degree of accuracy by using a linear mixed model. We obtain the result that attributes which strongly influence on the basic unit are temperature, tenant type and so on. From the observation of random effects, we know that the main factor to the basic unit is the individuality of tenants. We also clarify effective power saving behaviors after the Great East Japan Earthquake by a random effect.

    The authors propose a method to estimate the retention of stretch of polyvinyl chloride resin waterproofing sheet using image analysis techniques. The retention of stretch is regarded as the index of deterioration of a waterproofing sheet. Firstly, we originally developed a microscope for taking digital images of the surface of water proofing sheets that can capture the crack clearly. Then various kinds of existing image attributes are adopted to characterize the crack. These features are used as explanatory variables of multiple linearregressions to estimate the retention of the stretch. Estimation models were created and validated through cross validation tests. Finally, we succeeded in creating the estimation model that exhibits about 0.96 in determination coefficient.

    Street crimes such as auto theft and snatch theft account for approximately half of all crimes committed in Japan. The strategy of CPTED (Crime Prevention through Environmental Design) is now drawing the attention of urban planners and architects. Recently, the effectiveness of CPTED has been empirically examined using GIS. In this article, the authors investigate the relationship between snatch theft and the spatial attributes of the suburbs of Kyoto City. The spatial attributes considered include demographic data, land-use, visibility of space, and illuminance on the street. These attributes are analyzed with a significance test of mean as well as via CAEP (Classification by Aggregating Emerging Patterns). From these analyses, the authors obtain the following conclusions: (i) Mean values of pedestrians, population, and visibility of non-housing sites are relatively high at snatch theft locations. (ii) Illuminance on the street is not a predominant factor. (iii) Primary spatial patterns of snatch theft locations include relatively high visibility of a public facility site. (iv) The classification accuracy of CAEP is higher than that of other general classifiers. (v) In residential areas, the risk of snatch theft tends to be high only at particular sites. Meanwhile, downtown, it can occur frequently regardless of the site.

Since the rental office market tends to change periodically, we model the phenomenon of the periodic change of 2-dimentional time-series data of tenant and vacancy rate by the ellipse approximation method.&lt;br&gt;Average occupancy length is about 13 years. Attributes contributing to the increase of the occupancy length are building age and image of the rental room and etc. Average vacancy length is about 88 days. Attributes contributing to the decrease of vacancy length are good rental room image, high land price per floor-space ratio and the market condition such that its state is recovery or boom state, and etc.

    In this paper, we consider the evacuation problem in a network which consists of a directed graph with capacities and transit times on its arcs. This problem can be solved by the algorithm of Hoppe and Tardos [B. Hoppe, E. Tardos, The quickest transshipment problem, Math. Oper. Res. 25(1) (2000) 36-62] in polynomial time. However their running time is high-order polynomial, and hence is not practical in general. Thus, it is necessary to devise a faster algorithm for a tractable and practically useful subclass of this problem. In this paper, we consider a network with a sink s such that (i) for each vertex v not equal s the sum of the transit times of arcs on any path from v to s takes the same value, and (ii) for each vertex v not equal s the minimum v-s cut is determined by the arcs incident to s whose tails are reachable from v. This class of networks is a generalization of grid networks studied in the paper [N. Kamiyama, N. Katoh, A. Takizawa, An efficient algorithm for evacuation problem in dynamic network flows with uniform arc capacity, IEICE Trans. Infrom. Syst. E89-D (8) (2006) 2372-2379]. We propose an efficient algorithm for this network problem. (C) 2009 Elsevier B.V. All rights reserved.

    In the previous research we have revealed that kansei evaluation of rental office buildings much influences on the rent. Based on this result, in this article, we examine the kansei evaluation factor on entrance halls of office buildings in Osaka City. At first we examine the detail of entrances such as texture, lighting, visibility of a trash and so on. Then relationship between various kinds of building attributes and kansei evaluation is examined by correlation analysis and CAEP. As a result, it is clarified that some entrance attributes such as the size of an entrance hall and the existence of an auto door influences on both kansei evaluation.

    Property management (PM) service has been becoming the essential service for office buildings in the age of building stocks. In this study, we investigate how PM affects the rent of office buildings. 51 office buildings which are of small and middle scale in Shinbashi Area are selected for analysis. Criteria based on &amp;ldquo;kansei&amp;rdquo; judgment (the subjective judgment) of evaluators are proposed as the basis of evaluating the degree of maintenance and upgrade. Their values are derived by the field work and are integrated into the ordinary building specification and site environment data. Decision tree and rent prediction analyses are carried out. Through these analyses, we will show findings such that standard deviations of kansei judgment which are roughly discretized are important factors for rent prediction, and so on.

    In this paper, we consider the problem for determining an optimal location of a line facility in a city such as railway system. A line facility is modeled as a spanning tree embedded on the plane whose vertices represent stations and edges represent the rails connecting two stations, and people can travel not only by walk but also by using the line facility quickly. Suppose there are a finite number of towns in a city, only in which people lives. Then, our problem is to find a location of the stations as well as a connection of the stations such that the sum of travel time between all pairs of towns is minimum. Tsukamoto, Katoh and Takizawa proposed a heuristic algorithm for the problem which consists of two phases as follows. In the first phase, fixing the position of stations, it determines the topology of the line facility. The second phase optimizes the position of stations while the topology is fixed. The algorithm alternately executes these two phases until a converged solution is obtained. Tsukamoto et al. determined the topology of the line facility by solving minimum spanning tree (MST) in the first phase. In this paper, we propose two methods for determining the topology of the line facility so that the sum of travel time is minimized hoping to improving the previous algorithm. The first proposed method heuristically determine the topology by using evolutionary algorithm (EA). In the second method, we reduce our problem to minimum communication spanning tree (MCST) problem by making a further assumption, and solve it by formulating the problem as an integer program. We show the effectiveness of our proposed algorithm through the numerical experiments.

    This paper proposes a method for discriminating roof types and determining roof ridges from aerial images. Observing that according to the slope change of a roof surface its brightness changes, our method first approximates the histogram of brightness distribution as a smooth curve. We then extract effective characteristic variables to develop a discrimination model for classifying roof types into deck roof and inclined roof. For the roofs which are classified as inclined ones, we develop a method for classifying them into hip roofs and gables after extracting additional explanatory variables obtained by applying multiple regression to 3-dimensional brightness distribution. We finally applied the model to aerial image of residential area in Kyoto city, and observed that the classification ability of our proposed method was quite high.

    We propose the prediction models which tell who will really purchase an apartment from among those who visit a model room, and analyze the characteristic of purchase based on data-mining technique. The data of questionnaire collected from those who visited model rooms usually has a lot of missing values. In order to improve the precision of prediction, the original data is converted to the one and two dimensional probability data concerning purchase. This data conversion technique is applied to the data which an estate agent in Kansai owns. Decision-tree and logistic regression are applied in order to obtain prediction models. Precisions of three different data types: original categorical data, one dimensional probability data and two-dimensional one are compared. As a result of experiment, the followings are observed: 1. two dimensional probability data with logistic regression has the highest precision through different data, 2. customers having high purchase probability do not answer the questionnaire too much.

    A classifier for recognizing glass opening from architectural photographs based on extended Naive Bayes is proposed. From preliminary experiment we determine 3 possible candidates of attributes to represent color pixel each of which uses 6 color characteristics obtained together with x-y coordinates representing the relative position of the pixel in such a way that six color attributes are grouped into three pairs to be used in the extended Naive Bayes. Constructing the classifier based on the extended Naive Bayes which predicts whether a pixel represents glass or not, region segmentation is carried out based on MST. The computer experiments are carried out to demonstrate the effectiveness of the proposed method.

    This paper presents a floor layout algorithm for a two-story house based on enumeration algorithm as well as optimization algorithm. The process is as follows. First, all floor plans are created based on the floor enumeration algorithm and some of them which have higher values with respect to adjacent relationship and direction requirement are selected. Then, area and shape of those floor layouts are optimized by the tabu search. The proposed method has several advantages over existing methods; (1) Adjacency relationship among rooms is not fixed but the designer is allowed to explore all candidates based on enumeration algorithm of floor plans. (2) The enumeration algorithm employed here has found the all possible combination of 13 rooms. This number is enough to consider general floor layout of a house. (3) This method is applicable to a two-story house. A constraint of the two-story house is effectively used for searching solution in a short time.

    This paper proposes two methods for identifying images which contain a particular architectural component from a database of architectural images. Applying the techniques of pattern recognition and image retrieval, the first method does this task by using the overall color distribution and the layout. Measuring the similarity between a target image and those whose classes are already known, the method determines the class which a target image belongs to, and it can be applied to classification for many types of architectural components. The second initially selects characteristic elements which will be supposed to play an important role in identifying a particular component, and constructs a model for recognizing such an architectural component by using those characteristic elements. Thus, this method requires us to construct a recognition model from scratch separately for each distinct architectural component, but it attains a higher recognition ability than the first one. The paper then carried out computational experiments by applying the methods to the identification of &quot;tatami&quot; and &quot;lattice&quot; (koshi in Japanese). It was observed that the proposed methods attains a certain level of accuracy and thus are useful for identifying architectural components.

    When we plan a building, we need to predict the states of human and spatial usage of it. In such cases, discrete definition of space has advantage in modeling and calculation, but it has limitation in spatial reproduction of human behaviors. Therefore we need to define some physical values like distance or velocity continuously for reflecting detailed human behaviors. This paper describes a modeling method on human behavior in building space. This model consists of some elements : space, agents, furniture, and obstacles. In this model, all physical values are defined with continuous real number to make human behaviors as real as possible. In order to verify the effectiveness of the proposed method, some case studies are performed regarding simplified student hall.

    In this paper, a multi-agent system is employed to model urban systems. The supposed urban system is composed of three urban agents (residence, business, and service areas). Agents interact each other economically and pay land rents and moving costs. Agents who can not adapt to the urban system die. Agents who survive in the system move or create new agents according to the information of environment, internal states, and their own rules coded on genomes. When a new agent is created, his parent's genome is followed to the new one. Using this model, urban land-use pattern formation is simulated with three different distance restrictions. In the case of slight restriction, patterns are concentric and moving areas are wide. In the case of strong restriction, pattern become concentric and moving areas become shorter. Patterns are compared with the land-use of Osaka area using fractal dimension and its similarity is confirmed.

    Cities have grown and changed by intricate urban activities, and complex urban land-use patterns have formed. It is reasonable to suppose that complexity is an essential quality of cities. In this paper, the authors try to generate urban land-use patterns using an expanded cellular automata model. The proposed model is composed of three urban activities (residence, business, commerce) which interact economically. Each cell has three kinds of potentials corresponding to urban activities described with real numbers. These potentials can be considered to indicate populations or building areas. Potentials of each cell change by interactions, and each cell takes one of the following three actions: increase, disappearance, and no action. Using this model, urban land-use patterns can be generated. Comparing illustrated results with real cities, it can be said that this proposed model can simulate complex patterns of cities by relatively simple rules.

    In the field of construction and urban planning, arrangement problems are essential and important, and many methods for them have been studied. However, especially that of urban planning are complicated. If there are many numbers of elements, it may be difficult to discover optimum arrangement in realistic time by former methods. And worse still, the complexity of cities themselves makes systemization very difficult. In recent years, applying Genetic Algorithm (GA), which is a new method imitating the process of the living-thing evolution, to arrangement problems is studied. In this study, the authors try to reproduce urban land use by using GA with two local evaluation functions, i.e., geographical location conditions and degrees of mutual combination. First, a city arrangement model is proposed, and the coding methods of genes are shown. Then the system is applied to the land use of Kobe City. The applicability of this system is proved.

    In this study, we developed a method for generating omnidirectional depth imagesfrom corresponding omnidirectional RGB images of streetscapes by learningeach pair of omnidirectional RGB and depth images created by computergraphics using pix2pix. Then, the models trained with different series of imagesshot under different site and weather conditions were applied to Google streetview images to generate depth images. The validity of the generated depth imageswas then evaluated visually. In addition, we conducted experiments to evaluateGoogle street view images using multiple participants. We constructed a modelthat estimates the evaluation value of these images with and without the depthimages using the learning-to-rank method with deep convolutional neuralnetwork. The results demonstrate the extent to which the generalizationperformance of the streetscape evaluation model changes depending on thepresence or absence of depth images.

    A dynamic network introduced by Ford and Fulkerson is a directed graph with capacities and transit times on its arcs. The quickest transshipment problem is one of the most fundamental problems in dynamic networks. In this problem, we are given sources and sinks. Then the goal of this problem is to find a minimum time limit such that we can send the right amount of ow from sources to sinks. In this paper, we introduce a variant of this problem called the mixed evacuation problem. This problem models an emergent situation in which people can evacuate on foot or by car. The goal is to organize such a mixed evacuation so that an efficient evacuation can be achieved. In this paper, we study this problem from the theoretical and practical viewpoints. In the first part, we prove the polynomial-time solvability of this problem in the case where the number of sources and sinks is not large, and also prove the polynomial-time solvability and computational hardness of its variants with integer constraints. In the second part, we apply our model to the case study of Minabe town in Wakayama prefecture, Japan.

    Presentation type:Oral presentation (general)  

    Compared with the Osaka Midosuji Subway Line, the Osaka-Loop-Line has fewer passengers and there are concerns that the stations are not familiar to people. In this study, we analyze the degree of recognition about the name and position of 19 stations on the Osaka-Loop-Line from the questionnaire survey. Then, we consider the features of each station and problems of the Osaka-Loop-Line. We also propose a method to visualize the degree of recognition of each station as the size of double circles.

    本研究では、優れた避難所割り当てを発見する手法の提案を目的とする。しかし、避難所割り当てを優れていると評価するためには、多様な評価基準が存在し、一義的にそれを定めることは難しい。そこで、多目的最適化手法を用いて、パレート最適解となるような避難所の割り当てパターンを探索する。また、可能な避難所割り当てパターンを全て列挙したのちに、個々の解を評価して優れた避難所割り当ての抽出を行う列挙-評価手法を用いる。以上の二つの手法を用いて、大阪市住吉区における優れた避難所割り当ての発見を試み、手法の検討を行う。

    頑健な防災計画を実現するには、冗長性を持った設備計画とともに、考えうるシナリオすべてにおいて実際に計画を策定・検証できなければならない。しかし避難計画において、「1 秒でも早く多くの人が避難完了をするUniversally Quickest Flow(UQF)を求めるための計算は対象となる時間×空間に依存するネットワークに対する計算が必要になるため、多数のシナリオに対する繰り返し計算は困難であるという問題があった。本研究では動的ネットワークの計算に用いられるtime-expanded networkを用いずにUQF近似解を計算するアルゴリズムを提案する。提案手法の計算時間は対象となる空間の範囲のみに依存するため、南海トラフ地震の津波被害が懸念される大阪市のような大規模な都市においても高速にUQF の近似解を求めることが可能になる。

    Quickest transshipment problem is defined by a multi-source, multi-sink dynamic flow network, each source of that has a specified supply and each sink has a specified demand. The problem aims to finding a feasible dynamic flow which sends exactly the right value of flow from each source to each sink in the minimum period of time. In this note, at first we introduce three indicators of quickest evacuation; minimum evacuation completion time, minimum sum of transit times and lexicographically maximized number of evacuation completion people. Then we explain the last one is suitable for emergency evacuation situations like evacuation from tsunami, and suggest a heuristic for that.

    In this paper, we consider the following covering problem in graphs which is motivated by patrol route planning. Suppose that we are given a graph G=(V,E), a cost function c:2^E→R_+ and a requirement function r:V→Z_+, where R_+ and Z_+ represent the set of nonnegative reals and integers, respectively. Then, we consider the problem of finding minimum cost k subgraphs with a prescribed property (e.g., trees or paths) such that each v∈V is contained in at least r(v) subgraphs, where the cost of each subgraph is defined by the value of the function c for its edge set and the cost of k subgraphs is defined by the sum of their costs. Since this problem includes the travelling salesman problem as a subcase, it is NP-hard. In this paper, we consider two special cases of this problem. We first consider the problem where we cover the input graph by using trees. For this problem, we present a heuristic algorithm and we apply our algorithm to a numerical example arising from Nagoya City in Japan. We next consider the problem where we are given a path as the input graph and we cover it by using subpaths. For this problem, we first show that if each edge is given a cost and the cost of each path is defined by the sum of the costs of the edges contained in it, this problem can be solved in time bounded by a polynomial in the size of G, k and max{r(v)|v∈V}. Next, we show that if k=max{r(v)|v∈V}holds, this problem can be solved in polynomial time for a general cost function. Furthermore, we prove that if each edge is given a cost and the cost of each path is defined by the square of the sum of the costs of the edges contained in it, we can solve this problem more efficiently.

    Given a directed graph D=(V,A) and a set of specified vertices S={s_1,…s_d}⊆V with |S|=d and a function f: S→N where N denotes the set of natural numbers, we present a necessary and sufficient condition that there exist Σ_<s_i∈S>f(s_i) arc-disjoint in-trees denoted by T_<i,1>, T_<i,2>,…,T_<i,f(s_i)> for every i=1,…,d such that T_<i,1>,…,T_<i,f(s_i)> are rooted at s_i and each T_<i,j> spans vertices from which s_i is reachable. This generalizes the result of Edmonds [2], i.e., the necessary and sufficient condition that for a directed graph D=(V,A) with a specified vertex s∈V, there are k arc-disjoint in-trees rooted at s each of which spans V. Furthermore, we extend another characterization of packing in-trees of Edmonds [1] to the one in our case.
