Evaluating Mobility Impacts of Construction Work Zones on Utah Transportation System Using Machine Learning Techniques

Construction work zones are inevitable parts of daily operations at roadway systems. They have a significant impact on traffic conditions and the mobility of roadway systems. The traffic impacts of work zones could significantly vary due to several interacting factors such as work zone factors (work zone location and layout, length of the closure, work zone speed, intensity, and daily active hours); traffic factors (percentage of heavy vehicles, highway speed limit, capacity, mobility, flow, density, congestion, and occupancy); road factors (number of total lanes, number of open lanes, and pavement grade and condition); temporal factors (e.g., year, season, month, weekday, daytime, and darkness); weather conditions (rainy, sunny, and snowy); and spatial factors (road lane width, proximity, and number of ramps). Utah Department of Transportation (UDOT) is continuously collecting and storing project-related data. Due to the significant impact of work zones on traffic conditions, they are interested in evaluating the impacts of work zone attributes on mobility and traffic conditions of roadway systems within the state of Utah. Such an analysis will help the UDOT personnel better understand and plan for more efficient work zone operations, select the most effective traffic management systems for work zones, and assess the hidden costs of construction operations at work zones. To help UDOT address this problem, we propose a robust, deep neural network (DNN) model capable of evaluating the impacts of the factors mentioned earlier on the mobility conditions of Utah roadway systems. DNNs can capture all the relationships between input variables and output compared to traditional machine learning algorithms. The results of this project show that work zone features have an important effect on the traffic condition. In the end, the performance of the model is evaluated using three different measures, including R2 score, RMSE, and MAE. Comparing the measurement to previously conducted research, it is the first study that has attempted to investigate the effect of work zone features on hourly traffic volume

Generating Absolute-Scale Point Cloud Data of Built Infrastructure Scenes Using a Monocular Camera Setting

The global scale of Point Cloud Data (PCD) generated through monocular photo/videogrammetry is unknown, and can be calculated using at least one known dimension of the scene. Measuring one or more dimensions for this purpose induces a manual step in the 3D reconstruction process; this increases the effort and reduces the speed of reconstructing scenes, and induces substantial human error in the process due to the high level of measurement accuracy needed. Other ways of measuring such dimensions are based on acquiring additional information by either using extra sensors or specific classes of objects existing in the scene; we found that these solutions are not simple, cost effective or general enough to be considered practical for reconstructing both indoor and outdoor built infrastructure scenes. To address the issue, in this paper, we propose a novel method for automatically calculating the absolute scale of built infrastructure PCD. We use a pre-measured cube for outdoor scenes and a sheet of paper for indoor environments as the calibration patterns. Assuming that the dimensions of these objects are known, the proposed method extracts the objects’ corner points in 2D video frames using a novel algorithm. The extracted corner points are then matched between the consecutive frames. Finally, the corresponding corner points are reconstructed along with other features of the scenes to determine the real world scale. To evaluate the performance of the method, ten indoor and ten outdoor cases were selected and the absolute-scale PCD for each case was computed. Results illustrated the proposed algorithm is able to reconstruct the predefined objects with a high success rate while the generated absolute scale PCD is sufficiently accurate.This is the accepted manuscript.

Perkara ini sememangnya menjadi matlamat sistem pengurusan barat yang berorentasikan kebahagiaan keduniaan semata-mata tanpa mengira faktor modal insan yang perlu diberi perhatian. Kertas kerja ini akan menyingkap sistem pengurusan Islam, pendekatan organisasi dalam mendokong harapan negara untuk melahirkan insan yang sebenar-benarnya dan akhirnya akan mencapai konsep alfalah. Pengurusan Islam dalam pengurusan kerja akan menyentuh tentang konsep kerja dalam Islam dan pengawasan dalam bekerja. Sehubungan dengan itu pengurusan modal insan saling berkaitan dengan ahli organisasi itu sendiri atau tenaga kerja yang terdapat dalam organisasi itu. Justeru itu, matlamat akhir organisasi dalam Islam bukan hanya mengejar keuntungan semata-mata tetapi ada yang lebih penting dari keuntungan di dunia iaitu mencapai reda Allah SWT. Bermula dari langkah inilah manusia akan berfungsi menurut acuan yang benar dari Islam dan seterusnya melahirkan modal insan yang berkualiti dalam masyarakat dan Negara. Manusia adalah makhluk yang dipilih oleh Allah untuk menjadi khalifah di muka bumi. Kenapa Allah memilih manusia untuk memperkukuhkan ajaran Islam? Sudah tentu ada hikmah disebaliknya yang akan diungkap secara lengkap dalam kertas kerja ini

Investigando o efeito da moderação da imagem da marca em relações públicas percebidas em clientes de seguros do Irã em Ahvaz City

Customer loyalty has known as a very important factor in trade organizations. One of the important subjects for managers of this organizations, identify factors related to loyalty and understanding the relationships between these factors. Managers of Insurance industries, one of the important services in international level, are always trying to keep and develop relationships between their customers and create loyalty between them. This research helps to understand relationships between customer loyalty, customer satisfaction and mental image therefore it has provided significant scientific and application instructions in insurance management. The results show that public relations perceptions activities and brand identity has related with customer loyalty directly and brand image could influenced the relationship between PR and customer loyalty. If brand image is desirable then the effect of PRP on customer loyalty would lead to lower loyalty. The results of this research show that PRP does not have any relationship with loyalty directly. This result is not corresponding with An-Tine Hsieh and Chung-KaiLi research, but other factors are same. For this purpose we need to 150 questionnaires that distributed 200 pieces and collected 160 pieces.  La lealtad del cliente ha sido un factor muy importante en las organizaciones comerciales. Uno de los temas importantes para los gerentes de estas organizaciones es identificar los factores relacionados con la lealtad y comprender las relaciones entre estos factores. Los gerentes de las industrias de seguros, uno de los servicios importantes a nivel internacional, siempre intentan mantener y desarrollar relaciones entre sus clientes y crear lealtad entre ellos. Esta investigación ayuda a comprender las relaciones entre la lealtad del cliente, la satisfacción del cliente y la imagen mental, por lo que ha proporcionado importantes instrucciones científicas y de aplicación en la gestión de seguros. Los resultados muestran que las actividades de percepción de las relaciones públicas y la identidad de marca se han relacionado directamente con la lealtad de los clientes y que la imagen de la marca podría influir en la relación entre las relaciones públicas y la lealtad del cliente. Si la imagen de marca es deseable, el efecto de PRP sobre la lealtad de los clientes daría lugar a una menor lealtad. Los resultados de esta investigación muestran que PRP no tiene ninguna relación con la lealtad directamente. Este resultado no corresponde con la investigación de An-Tine Hsieh y Chung-KaiLi, pero otros factores son los mismos. Para este propósito, necesitamos 150 cuestionarios que distribuyeron 200 piezas y recolectaron 160 piezas.A lealdade do cliente tem sido um fator muito importante nas organizações comerciais.
