  • STREAMLINING PEDESTRIAN FLOW IN INTERSECTIONS BY USING A PEDESTRIAN-ROUNDABOUT (PART 1): PROPOSAL AND EMPIRICAL VERIFICATION OF PEDESTRIAN-ROUNDABOUT

     View Summary

    <p> 1. Introduction</p><p> In facilities hosting large crowds, such as railway stations, stadiums, and convention centers, visitors in transit have different destinations. Pedestrian flows are therefore complex, unlike single-direction building evacuations. When multiple flows cross, they can easily become stacked because of the sudden increase in density and the difficulty in avoiding other people coming from different directions. Moreover, walking in a disordered crowd is mentally stressful, and even poses the risk of colliding with others. Solving such congestion is essential for flow efficiency, safety, and user comfort.</p><p> This paper proposes a new flow-control system called a Pedestrian-Roundabout, and reports on its effects through the results of two sequential full-scale experiments.</p><p> </p><p> 2. Pedestrian-Roundabout Proposal</p><p> The Pedestrian-Roundabout is an architectural device developed by the authors to optimize the complex pedestrian flows at intersections. In a Pedestrian-Roundabout, a large obstacle several meters in diameter is placed at the center of a pedestrian intersection and, similar to how an automobile roundabout works, pedestrians are required to walk in one direction around it.</p><p> </p><p> 3. Methodology</p><p> To determine the effects of placing such an obstacle on the crowd flow characteristics and detailed walking behavior at the crossing point, we performed two full-scale laboratory experiments: one in 2018 with 48 participants, and another in 2019 with 96 participants. The shape of the obstacle, pedestrian density, and walking direction constraint were all varied in the experimental conditions to determine the effective factors for traffic flow optimization. A short questionnaire evaluating the psychological quality of the walk was also conducted after each trial.</p><p> A very accurate pedestrian trajectory data associated with each pedestrian's ID was obtained using two-dimensional barcode markers and the authors' original image processing programs. Based on these IDs, each trajectory was connected to the other participants' information, including their psychological walk evaluation.</p><p> </p><p> 4. Results</p><p> Diagrams in Fig. 8 indicate the walking trajectories in some representative cases with an emphasis on walking speed reduction. When four flows crossed in a normal right intersection (Fig. 8 4X-FR-VO), the center part became highly congested with pedestrians walking in different directions (Fig. 9). In such a complex crossing situation, pedestrians needed to perform avoidance behavior, namely, speed reduction and detouring, quite often. According to the questionnaire results, the participants perceived the walk as more difficult when they necessitated stronger avoidance.</p><p> By just placing a cylinder shape obstacle with a 4 m diameter in the center of this intersection (Fig. 8 4X-FR-CI), it was observed that the speed reduction was restrained. Furthermore, constraining the walking direction to one-direction (Fig. 8 4X-RA-CI) reinforces this effect, and the trajectories became smoother due to the less detouring around others. The results indicated also that the 4 m diameter obstacle worked more efficiently than a smaller size 2 m obstacle. When the obstacle had edges in the plane, the flow stacked nearby the corners (Fig. 8 4X-FR-SQ0, 4X-FR-DI0, 4X-FR-DI30).</p><p> </p><p> 5. Conclusions</p><p> According to the results of our experiments, placing a large obstacle at the center of a complex intersection and letting pedestrians detour around it have positive effects on streamlining the flows. Thus, by introducing the Pedestrian-Roundabout, a reduction in the congestion and a walking difficulty improvement can be expected.</p>

  • Encounters and conversations: an office cafe space as a "magnet space"

    Tai Satoh, Tomonori Sano

    JAPAN ARCHITECTURAL REVIEW   3 ( 4 ) 579 - 589  2020.10

     View Summary

    A study was conducted on the activities of office workers at a cafe space with a lounge in a free-address office to investigate communication at a "magnet space." The major results were as follows: (i) The encounter probability between two office workers at the magnet space could be estimated by a formula based on Little's law, which considers the frequency of use as well as the mean and standard deviation of the stay time. Analyzing more data for the estimated formula of the encounter rate, which is suggested in this study, can confirm more thoroughly the actual situation of an encounter and conversation in the magnet space of the office. (ii) Installing a lounge-like workspace adjacent to the cafe space increased the encounter probability between workers at the cafe space.

  • Compression of Pedestrian Crowd in Corner Turning Subject experiment-based analysis of walking trajectories

    Mineko Imanishi, Tomonori Sano

    Collective Dynamics   5  2020.03

     View Summary

    In this study, pedestrian crowd dynamics at corner turns were investigated by analyzing pedestrian trajectories in a subject experiment for building more reliable, general-purpose, pedestrian simulation models. An experiment under laboratory conditions was conducted wherein a pedestrian crowd walked straight for a short distance before turning into a right-angled corner built with partition walls; the opposite sides were unwalled. Trials were performed with different widths and densities of initial participant positions. Finally, the trajectories of the pedestrians were extracted from a video through computer image analysis. The results demonstrated that pedestrian behavior at corner turns depends on lane position, lane distance (from the wall), and crowd density.

     View Summary

    This reseach aimed to evaluate the actual evacuation risk of nursary home in high-rise building for the zero-waiting list policy. Field survery and evacuation drill research were conducted in several nursary homes of different size and in verious location.These results showed that assisted and guided evacuation for nursary home children should be done. And we clalified that the number of registered nursary home staff was lower than that for assited evacuation by the organization of related law for nursary home. Besides, the nursary home on much upper floors in high-rise bulidning had higher risk than that under 4th floor because the regulation of nursary home on 4th floor and over was more strict however it was not changed accoding to the number of floor

  • VR・ARを用いた災害時用援護者を含む避難誘導計画・介助避難計画の検討

    2019  

     View Summary

    VR・ARを用いた災害時用援護者を含む避難誘導計画・介助避難計画の検討として、被験者を用いた予備実験及び本実験を行った。具体的には、VR空間内に誘導灯を設置した実空間をモデルとした空間を設置して、避難出口探索実験を実施した。この際、誘導灯の設置方法、被験者の視点を実験条件として変更し、健常者と災害時要援護者として車いす利用者を想定した実験を行った。被験者数は40名である。結果として、吊り下げ型の誘導灯は床面型の誘導灯よりも遠方から視認されること、誘導灯を斜め投方向から見る位置では視認性が下がることが明らかになった。成果は、日本建築学会、日本火災学会等の国内学会にて発表予定である。

  • 高層階における弱者の火災避難安全に関する研究

    2003  

     View Summary

    高層階における弱者の火災避難安全の確保を目的として、以下の調査、実験を行った。■研究概要①弱者の身体寸法・動作寸法・身体能力等のデータの収集 弱者の安全な避難方法を計画するためには、その人の避難時に発揮できる能力を人間工学的な観点から把握する必要がある。そこで、既存の書籍・資料・webサイト上のデータベースを中心に、高層階からの避難に関連する身体能力等のデータの収集・整理を行った。②高層階からの階段降下避難実験②-1 階段降下時の健常者の歩行速度の算定実験 本研究では、災害弱者との比較のために、健常者の単独での階段降下について実験を行った。実際の事務所ビルの特別避難階段を実験場所とし、被験者20名について、20階層降下する場合の歩行速度を各階ごとに算定した。②-2 避難用車いすを利用した階段降下実験 2001.9.11のWTCテロ事件において、高層階に勤務していた車いす利用者が、避難用車いす(Evacuation Chair)という階段を降下できる車いすにのりかえ、介助されて避難し、助かった事例が報告されている。筆者らは、国内での導入例・研究例のほとんどない避難用車いすの操作性についての実験を行い、論文に発表した。ここでは継続研究として、避難用車いすの実用可能性について検討を行った。具体的には、被験者20名について、20階層降下する場合の歩行速度を各階ごとに算定した。また、実験の様子をビデオカメラによって撮影した。加えて、避難階段の踊り場部分での通過軌跡を、モーションキャプチャシステムを用いて算定し、事前訓練の必要性を明らかにした。■ 研究成果上記の研究を通して、国内では導入例が少ない「避難用車いす(Emergency Evacuation Chair)」の操作特性について人間工学的観点から基礎的なデータを得た。当該機器は、米国、英国等で導入されているが、人間工学的観点からデータを収集、分析された研究は、世界的に見ても少ないことから、本助成によって、有効な研究成果が得られたと考えている。上記の調査結果及び実験結果は、国際会議2件および国内学会1件において、発表を行った。国際会議:CIB-CTBUH Proceedings of the International Conference on Tall Buildings, Malaysia(1編)国際会議:6th Asia-Oceania Symposium on Fire Science & Technology, Korea(1編)国内会議:日本建築学会関東支部研究発表会(4編)
