Sphere Of Influence

To evaluate or predict human behavior, extraction of characteristic patterns from actual crowd scenes and crowd simulation in different situations based on general human behavior model are needed. We use changes in a spatial feature formed by individual movement called a "dominant region", a type of dynamic personal space. In the paper, a basic concept and calculation of the dominant region and its applications are presented. Experiments show that the proposed feature is useful in evaluating and simulating human behavior.

Dense Crowd

Computer simulation of dense crowds is finding increased use in event planning, congestion prediction, and threat assessment. State-of-the-art particle-based crowd methods assume and aim for collision-free trajectories. That is an idealistic yet not overly realistic expectation, as near-collisions increase in dense and rushed settings compared with typically sparse pedestrian scenarios. Centroidal particle dynamics (CPD) is a method we defined that explicitly models the compressible personal space area surrounding each entity to inform its local pathing and collision-avoidance decisions. We illustrate how our proposed agent-based method for local dynamics can reproduce several key emergent dense crowd phenomena at the microscopic level with higher congruence to real trajectory data and with more visually convincing collision-avoidance paths than the existing state of the art. We present advanced models in which we consider distraction of the pedestrians in the crowd, flocking behavior, interaction with vehicles (ambulances, police) and other advanced models that show that emergent behavior in the simulated crowds is similar to the behavior observed in reality. We discuss how to increase confidence in CPD, potentially making it also suitable for use in safety-critical applications, including urban design, evacuation analysis, and crowd-safety planning.

Assessment And Treatment

Current ambulatory technologies are highly relevant for neuropsychological assessment and treatment as they provide a gateway to real life data. Ambulatory assessment of cognitive complaints, skills and emotional states in natural contexts provides information that has a greater ecological validity than traditional assessment approaches. This issue presents an overview of current technological and methodological innovations, opportunities, problems and limitations of these methods designed for the context-sensitive measurement of cognitive, emotional and behavioral function. The usefulness of selected ambulatory approaches is demonstrated and their relevance for an ecologically valid neuropsychology is highlighted.

Abstract: This Research is one of methods to figure out the benefits from the use of marking road. A special handling is needed to the violations of Marking Road especially for populated area that located on lack of attention area. Sunday morning market of University of Gadjah Mada has tight activities every Sunday morning and Olahraga street is the study sample that represent other streets. This research using qualitative methods by gathering data field and interview to obtain results such as site size, history, behavior setting, behavior mapping, and personal space. The use of marking road must be related to territorial division of activities such as function and activity that is happening.  Territory happened through a different process every its object.  There are two divisions of territory for Sunday Market Morning that are Primary Territory and Secondary Territory. Primary Territory includes kiosk traders, parking attendants, and visitors. On the other hand, Secondary territory is a space that is used together such as secondary road or the divisor road. After the division of territories is obtained then the data is analyzed to get some alternatives. The alternatives are compared to get the pattern of territories that can be arranged through the use of Marking Road.Keywords: Marking Road, Territorial, Sunday Morning Market of Gadjah Mada University    Abstrak: Penelitian ini merupakan salah satu cara untuk mengetahui manfaat dari penggunaan marka jalan. Pelanggaran terhadap marka jalan perlu penanganan khusus terutama daerah-daerah padat yang terdapat pada jalur jalan lingkungan yang kurang menjadi perhatian. Pasar Minggu Pagi (Sunday Morning Market) Universitas Gadjah Mada Yogyakarta termasuk memiliki kegiatan padat setiap minggu pagi dan jalan olahraga sebagai sampel penelitian mewakili jalan yang lain. Penelitian ini menggunakan metode kualitatif dengan mengumpulkan data lapangan dan wawancara sehingga mendapatkan data seperti ukuran site, sejarah, behavior setting, behavior mapping, dan personal space. Penggunaan marka jalan pasti berhubungan dengan pembagian batas teritori kegiatan seperti fungsi dan aktivitas yang terjadi. Teritori terjadi melalui proses yang berbeda-beda tiap objeknya. Pada Sunday Morning Market terdapat pembagian dua teritori yaitu primary territory dan secondary territory. Primary territory meliputi pedagang kios, pelaku parkir, dan pengunjung. Sedangkan secondary territory merupakan ruang yang dipakai bersama seperti jalan sekunder ataupun jalan pembagi. Setelah didapatkan pembagian teritorinya maka dianalisis dan mendapatkan beberapa alternatif. Alternatif tersebut dibandingkan sehingga mendapatkan pola teritori yang dapat diatur melalui penggunaan marka jalan.Kata kunci: Marka Jalan, Teritorial, Pasar Minggu Pagi Universitas Gadjah Mada
