Comparative Analysis and Assessment of States’ Traffic Management Center Programs

This research presents a step-by-step guideline for traffic data collection standards set by the Institute of Transportation Engineers (ITE) and American Association of State Highway and Transportation Officials (AASHTO). This study reviews manual and automatic methods of traffic counting and provides detailed information on traffic volume and vehicle classification studies. This research also provides a detailed analysis of the Delaware Department of Transportation (DelDOT)-TMC (Transportation Management Center) websites and compares it to selected Department of Transportation websites of other states such as Vermont, Connecticut, New Jersey, Pennsylvania, California, Texas, and Virginia. The purpose of the comparison is to analyze the data sources;user friendliness, accessibility, types of data available, presentation formats, and style for each state to determine how they compared to DelDOT-TMC. Although there were some similarities, the findings suggest that two major differences are present. The overall results revealed that DelDOT-TMC provides limited traffic and roadway weather data, and presentation formats to the public as compared to the other states. Further, a unitless variable, called the Capacity Factor (Q), has been developed within this study to represent this relative comparison. This study shows that DelDOT TMC performs well within the group of selected states and better than selected states of similar size and most selected states of larger size;where only Virginia performs better then DelDOT TMC. DelDOT TMC does not perform as well as selected neighboring states;however, it performs in an acceptable range relative to neighboring states.

The Center of Crisis Management and Situation Room

Countries have to pre-evaluate threats and risks that may incur their national security and national interests, take the necessary preventive measures timely, and pursue decisive policies within the limits of the possibilities of their national power, by keeping a close watch on ongoing and conceivable crises and new developments. Like statesmen, also the international security organizations have to foresee the coming or anticipated threats and opportunities, take the necessary precautions and when necessary even to react by using force. Starting from time of peace, all these require an effective crisis management system that would warn and manage the threats that would create such crises. There are, however, crisis management centers and situation rooms in the focal points of the physical substructure of the crisis management system. In this article, by looking at the attributions of an effective crisis management system, structure of the crisis management centers and situation rooms will be questioned at international and national levels.

Platform Construction of Regional Energy Management Center

Based on the analysis of different requirements of energy management center construction and the data acquisition of various industries in wide area network, as well as the practices of real-lime online system, the paper puts forward the construction scheme of regional energy management center （REMC） which can achieve real time online monitoring of organizations＇ energy consumption via data collection, and also proposes the design idea of energy data acquisition based on national standards.

Research and Design of Network Management Construction Based on Mobile AGENT

The technical characters of mobile agent （MA） originated in the distributional artificial intelligence domain is introduced. A network management construction based on agent （NMCA） is then proposed. The NMCA structure features are elaborated in detail. A prototype design of NMCA is given by using the jKQML programming. The establishment of NMCA platform will be helpful to reduce the correspondence load of network management and improves the efficiency and the expansion ability of network management systems.

Utilization and Usability of Delaware Traffic Management Products: A Survey and Challenges

To address the growing problem of congestion, delays, and overall traffic issues, DelDOT (Delaware Department of Transportation) established the Transportation Management Center (TMC) in 1997. DelDOT-TMC also coordinates and manages DelDOT’s response to any incident that impacts the multimodal transportation system within the state of Delaware. Among other things, DelDOT-TMC collects traffic, roadway weather, and hydrological data using over a thousand monitoring devices installed throughout the state of Delaware. After data has been obtained, DelDOT-TMC analyzes and disseminates real-time travel information to the public through DelDOT’s website (online interactive maps), smartphone application, traffic advisory radio, and social media sites such as Twitter, Facebook, YouTube, Blog, and Flickr;however, the utilization and usability of this information by the public are, for the most part, unknown. The purpose of this study is to evaluate the global responsibilities of DelDOT-TMC and assess the process that DelDOT-TMC uses to gather, process, analyze, and distribute traffic and roadway weather data to the public. The study employs a survey to assess the utilization of DelDOT-TMC’s products, i.e., DelDOT Mobile App, WTMC 1380 AM travel advisory radio, DelDOT’s public website, DelDOT’s social media, as well as the usability of the DelDOT mobile app to check DART (Delaware Authority for Regional Transportation) First State transit service schedules.

Dynamic System Level Frequency Spectrum Allocation Scheme Based on Cognitive Radio Technology

Cognitive radio is being widely discussed,and resource allocation scheme is drawing a lot of attention.Although the existed resource allocation strategies have successfully enhanced spectrum efficiency,some critical challenges still remain unanswered such as the jointly consideration of the efficiency and fairness,the rational description of the spectrum resources,and the execution mode of the spectrum allocation.This paper presents a system level dynamic frequency spectrum allocation scheme based on a central heterogeneous network architecture,evaluates the matching degree of the spectrum demand and the available spectrum resources with corresponding matrices,jointly considers the efficiency and fairness of different cognitive radio systems.Simulation results and the application scenario are also presented and analyzed.

Prevalence and Associated Factors of Eating Disorders in Weight Management Centers in Tanta, Egypt

Background： Eating disorders （EDs） are serious illnesses associated with medical complications and have been increased, especially among societies with an excessive concern about weight, shape, or appearance. This study aimed to investigate the prevalence of EDs among the individuals attending weight management centers and its associated factors. Methods： A cross-sectional study was carried out among individuals attending four weight management centers in Tanta, Gharbia Governorate, Egypt during the period from July to December 2016. Precoded interview questionnaires were used to identify the following data： sociodemographic characteristics and medical history of depression or psychological disorders and the Eating Attitude Test （EAT-40） was used to assess the attitudes, behavior, and traits associated with the EDs. Results： A total of 400 participants （I 12 males and 288 females） were included in the study. According to EAT-40 questionnaires, the prevalence of positive and negative EDs was 65.0% （n = 260） and 35.0% （n = 140）, respectively. EDs were more likely reported by females, married singles, rural residents, those with higher education, and nonworking or part-time working patients, those who were overweight or obese, and who were suffering from depression or any psychological problems. Logistic regression analysis revealed that the independent predictors of EDs were age （adjusted odds ratio [OR]： 1.06）, nonworking （adjusted OR： 2.32） or part-time working （adjusted OR： 2,18）, increased body weight （adjusted OR： 2.66 for overweight and adjusted OR： 1.24 for obese）, and having a history of depression or any psychological problem （adjusted OR： 2.76）. Factor analysis of EAT-40 revealed four factors （eating behavior, diet-related lifestyle, weight concern, and food preoccupation） that were responsible for 33.2% of the total variance. Conclusions： EDs are prevalent among individuals attending the weight management centers in a northern city in Egypt. Specific management strategies are warranted to address this commonly prevalent disease.
