PENGARUH HAMBATAN SAMPING TERHADAP KINERJA RUAS JALAN SATU ARAH DAN DUA ARAH TANPA MEDIAN DI KOTAMADYA MATARAM

Street Catur Warga and Dr. Wahidin did not have enough stops, so many vehicles stopped on the shoulder of the road and parked on the side of the road. The number of people crossing the road and the number of vehicles entering/exiting the road causes a reduction in the speed, volume and capacity of the road so that at certain hours traffic jams often occur. This study analyzed the side friction, volume and speed of Catur Warga and Jalan Dr. Wahidin used the 1997 MKJI method. The results of the analysis on one-way roads, especially the Catur Warga road, had side friction, volume and speed respectively, namely 790.7 events/hour, 1533.75 smp/am and 46.08 km/hour. While the two-way street, Jalan Dr. Wahidin, has side friction, volume and speed of 403.1 events/hour, 1916.15 smp/hour and 38.58 km/hour. From the results of the regression analysis, side friction is very influential on the volume and speed of traffic. This can be seen from (r) in the range of 0.7 < r < 0.9 where the number shows a strong influence and 0.9 < r < 1 indicates a very strong influence. The results of partial regression analysis show that on the Catur Warga road, the side barriers that have the most influence on volume are Parking and Vehicle Stops (PSV), while at speed, namely Vehicles Exiting/Entering Roadside Land Use (EEV). On the Dr. Wahidin the side friction variable that has the most influence on volume is Pedestrians (PED), while at speed, namely Parking and Vehicle Stops (PSV).

TINJAUAN HAMBATAN SAMPING, KAPASITAS DAN TUNDAAN LALU LINTAS PADA SIMPANG TIDAK BERSINYAL DIKOTA MATARAM

On several roads in the city of Mataram, such as the Dr. Wahidin road, there are many shops that do not have enough parking space, so many vehicles are parked on the shoulder of the road and even on the road. The presence of pedestrians crossing the road and the activity of vehicles entering/exiting the road affect the speed of traffic, and the capacity of the road so that at certain hours there are frequent traffic jams. This of course will have an impact on the delay at the intersection of Dr. Wahidin. As for the Caturwarga street, there are schools, hospitals and shops that do not have sufficient parking space, many vehicles that drop off and pick up passengers and vehicles that enter and leave the land use side of the road. Of course, this condition affects the smooth flow of traffic, so it has an impact on delays at the Catur Warga intersection. This study analyzes side resistance, capacity and delay at unsignalized intersections on Caturwarga and Dr. Wahidin roads. The total of this side resistance will be used to analyze how much influence it has on the delay using the 1997 MKJI method. The results of the analysis at the Catur Warga intersection have side friction, and the delays are 790.7 events/hour, 16.63 seconds/smp. Meanwhile, at the Dr. Wahidin intersection, the side friction and delays are 403.1 events/hour and 17.00 seconds/pcu, respectively. From the results of regression analysis, side barriers affect traffic delays by 89.7% and at Dr. Wahidin intersections by 79.7%. Partially at the Catur Warga intersection, the side friction variable that has the most influence on delays is Exit/Entrance Vehicles on the land use side of the road (EEV). On the Dr. Wahidin road, the side obstacle variable that has the most influence on delays is Pedestrians (PED).

THE EFFECT OF BUILDING HEIGHTS ON OUTDOOR WIND ENVIRONMENT OF THE RESIDENTIAL SECTOR / CAS OF EL EULMA CITY, Algeria

The residential open spaces microclimate especially the wind environment, is widely affected by its surrounding buildings. This paper aims to assess the influence of residential buildings on urban microclimate in the North Est region of Algeria. This assessment performed using the in-situ measurements of different microclimate’s settings, during summer and winter. Comparing between two existing city housing blocks, the present study showed that, the higher one results lower temperatures outdoor spaces in winter and summer. Furthermore, the passage under the building improves the accessibility, the ventilation in the inside corner of the city block, but may increase the wind speed so it causes pedestrians discomfort and safety issues.

Dynamical models of a suspension bridge driven by vibration data

The great availability of measurement systems permits to acquire quite easily data related to structural oscillations in operational conditions. This occurrence may permit to enhance our capability to data-driven computing using directly experimental data and pertinent constraints and conservation laws, such as compatibility and equilibrium, surely certain. In the paper, a methodology will be presented to furnish an analytical mechanical model of a suspension bridge in which the main parameters can be derived from vibration measurements. In this respect, Polymax and Enhanced Frequency Domain Decomposition identification procedures are used to determine a complete modal model which is used to evaluate an error function. Optimization algorithms are used to evaluate the function minima in the fundamental parameter space. The procedure will be validated by results coming from a sophisticated finite element model for which geometric measurements are included through a 3D point cloud geometrical model and a consequent Building Information model (BIM) constructed with images acquired by unmanned aerial vehicle (UAV). The case study of the pedestrian cable suspension Polvorines bridge (100 meters of span) is considered to demonstrate the procedure, due the test campaign conducted on March 2020.

MICROESCALA, MOVIMENTO DE PEDESTRES E NÍVEIS SOCIOECONÔMICOS: UM ESTUDO EMPÍRICO

A caminhabilidade é entendida como a qualidade urbana com duas principais escalas, a mesoescala e a microescala. A microescala abrange elementos como a qualidade das calçadas, cruzamentos, iluminação, vegetação, entre outros. As características desses elementos podem influenciar os comportamentos de caminhada e variam de acordo com os níveis socioeconômicos do território. Portanto, o objetivo principal desta pesquisa é analisar a relação entre a caminhabilidade na microescala e o movimento de pedestres, considerando diferenças socioeconômicas em Cambé-PR. Para tanto, a ferramenta MAPS-Global foi aplicada por meio do uso do Google Street View em 635 segmentos de via selecionados aleatoriamente em 26 setores censitários. Após o levantamento, os dados foram sistematizados, indicando uma pontuação acerca do nível de caminhabilidade dos segmentos. Finalmente, foram realizadas análises de clusters para verificação da relação entre caminhabilidade na microescala, renda por setor e níveis de caminhada, obtidos do Plano De Mobilidade de Cambé-PR. Foi possível identificar que regiões de alta renda e regiões mais caminhadas pelos pedestres são aquelas com maiores escores médios gerais de caminhabilidade em seus segmentos. Tais resultados contribuem com o contexto brasileiro sobre caminhabilidade na microescala, considerando as inerentes variações sociais do espaço urbano.Palavras-chave: Ambiente Construído, Caminhada, Planejamento Urbano

Explaining the criteria of being present and psychological well-being in natural recreational spaces of Tabriz

بسیاری از پژوهش‌های حوزة سلامت روان نشان می‌دهند حالت ذهنی انسان به میزان زیادی فاقد آگاهی است؛ به این معنا که انسان‌ها بیشتر اوقات یا غرق در خاطرات گذشته‌اند یا دربارة آینده رؤیاپردازی می‌کنند و کمتر از حضور در زمان حال لذت می‌برند. روان‌شناسان علوم محیطی با تلفیق چند مفهوم کلیدی ازجمله تأکید بر تجربة حضور، لذت از زندگی در زمان حال و نقشی که این موضوع در ارتقای سلامت روانی شهروندان دارد، مفهوم جدیدی را با عنوان «ذهن‌آگاهی» مطرح کرده‌اند. هدف اصلی پژوهش حاضر، تبیین معیارهایی است که از احساس و زبان شهروندان دربارة تجربه، لذت حضور و ذهن‌آگاهی در محیط‌های تفرجگاهی استخراج شده است. در راستای اهداف تعریف‌شده، از مراجعان به دو فضای تفرجگاهی طبیعی ایل‌گولی و عونبن علی تبریز نمونه‌گیری و مصاحبة هدفمند انجام و با تحلیل محتوای کیفی، کدهای لازم استخراج شد. این کدها در ادامه به 6 مقولة اصلی (معیار) و 18 زیرمقوله (زیرمعیار) تبدیل شدند. صحت مدل استخراج‌شده با تکنیک تحلیل عاملی تأییدی آزموده شد. در انتها با بهره‌مندی از آرای خبرگان در حوزة شهرسازی و طراحی محیطی و استفاده از تکنیک تحلیل سلسله‌مراتبی، معیارها و زیرمعیارهای مدل وزن‌بندی شد. نتایج این پژوهش نشان می‌دهد احساس آرامش در محیط طبیعی، مؤثرترین معیار به‌منظور القای حس ذهن‌آگاهی و تجربة لذت‌بخش از حضور در این فضاست؛ در حالی که معیارهای زیبایی طبیعت، صمیمیت، عظمت و شکوه، سرزندگی و درنهایت معنویت و امکان کشف محیط در رتبه‌های بعدی اهمیت قرار دارند. گفتنی است معیارها و زیرمعیارهای استخراج‌شده از مدل ذهن‌آگاهی در محیط‌های طبیعی، گذشته از کاربرد برای ارزیابی کیفیت دیگر محیط‌های طبیعی و مصنوع، به برنامه‌ریزان، طراحان و مجریان مناظر طبیعی در ارتقای طرح‌های پیشنهادی و اجرایی مناظر طبیعی کمک شایانی می‌کنند.

Mortalidade por acidentes de transporte terrestre no estado de São Paulo: análise da tendência nos anos de 2000 - 2017

O objetivo deste trabalho foi descrever o perfil da mortalidade por acidentes de transporte terrestre (ATT) no estado de São Paulo e os efeitos da Lei Seca sobre a taxa de mortalidade. Foram selecionados, pelo Sistema de Informações sobre Mortalidade (SIM), os óbitos com os códigos V01-V89 determinados na 10ª revisão da Classificação Internacional de Doenças (CID-10), tendo como causa o ATT. Calculou-se, para 8 anos antes e 9 anos após a Lei, a taxa de mortalidade por ATT de acordo com faixa etária e sexo. Além da distribuição (absoluta e percentual) da mortalidade por ATT relacionados as variáveis: faixa etária, sexo, raça, escolaridade, estado civil, categoria da CID-10 e por departamentos regionais de saúde (DRS). Os resultados mostraram uma tendência de aumento de óbitos por ATT antes da Lei e uma queda nos óbitos após a Lei, além de maior frequência de mortalidade no sexo masculino, entre 20-39 anos, solteiros, brancos, com escolaridade de 4-7 anos antes da Lei e de 8-11 anos após a Lei. Maior mortalidade nos Municípios da Grande São Paulo, Baixada Santista, Registro e Taubaté tanto antes como após a Lei; maior registro de mortalidade por outros ATT antes da Lei e uma maior frequência de pedestres traumatizados por ATT após a Lei. Conclui-se então que a implementação da Lei Seca interferiu positivamente na taxa de mortalidade observada no período e nas variáveis analisadas.

Bu çalışmanın amacı, Burdur kenti açık-yeşil alanlarının mevcut durumunu incelemek, yeterlilikleri ve işlevsel niteliklerini tespit etmektir. Bu amaçla, açık-yeşil alanlardan meydanlar, parklar, çocuk oyun alanları, spor alanları, okul bahçeleri, resmi kuruluşlar, mezarlıklar, pazaryerleri ile yollar, yaya yolları, refüj ve bulvarlar incelenmiştir. Burdur kentinde kişi başına 8,4 m2 açık-yeşil alan düştüğü ve bu alanın yetersiz olduğu belirlenmiştir. Bu çalışmanın bulguları bütün olarak düşünüldüğünde, Burdur kenti mevcut açık-yeşil alanlarının gelişigüzel bir dağılıma sahip oldukları sonucuna ulaşılmıştır. Ayrıca, kentte yer alan açık-yeşil alanların bitkilerinin estetik ve işlevsel özellikleri açısından kent insanının ihtiyaçlarını karşılayacak nitelikte olmadığı, bitkisel tasarımın yetersiz olduğu ve kullanılan bitki türlerinin mekanın kalitesini artırmada yeterli olmadığı gözlenmiştir. Sonuç olarak, Burdur kentini modern, yaşanabilir ve kaliteli bir mekan haline getirmek için, açık-yeşil alanları nitelik ve nicelik yönünden konunun uzmanları tarafından planlanması ve tasarlanması uygun olacaktır.

Estimation of Self-Posture of a Pedestrian Using MY VISION Based on Depth and Motion Network

A system is proposed that performs gait analysis of a pedestrian to improve a walk posture and at the same time to prevent a fall. In the system, a user walks with a chest-mounted camera. His/her walking posture is estimated using a pair of images obtained from the camera. Normally it is difficult to estimate the camera movement, when the parallax of the image pair is small. Therefore, the system uses a convolutional neural network. Optical flow and camera movement, and depth images are estimated alternately. Satisfactory results were obtained experimentally.
