The high traffic density causes traffic congestion on the road, causing delays before it reaches its destination, in addition to the stress and high psychological impact on the driver, it also results in staff and staff being late for work and students being late for school, With frequent accidents on these busy roads. Congestion has a lot of reasons, one of them is poor infrastructure that leads to a state of congestion, a significant increase in the number of vehicles, a lack of prior information for road users about the traffic situation, Division of traffic management into several departments (Public works, municipality, security, transport…). They become ineffective in some areas, aggressive driving style Which may be an effective factor in creating congestion, in addition to the use of individual transport rather than mass transport. Latakia suffers from a very poor transport system, and the indiscriminate movement of vehicles on its streets. This has been accompanied by increased traffic, which has led to many problems. The most important is the problem of congestion, in terms of increasing the values of delay times in different road sectors. This has contributed to major traffic crises and congestion. It affected service levels on arterial streets in the city's downtown, in the absence of rush-hour studies. Two main streets have been selected in the commercial and downtown center of Latakia City, which is an important arterial street for the distribution of movement. These arterial streets connect the commercial and administrative center of the city with the other parties of the city. The moving controller analyses a large number of actual speeds of the vehicle, measured in each sector, with a view to estimating congestion, calculating its indicators, and determining peak hours. Congestion levels were inferred based on the values of the speed performance index, and the average speeds of daytime and evening peak hours have been mapped to considered street sectors.

The research presents a study and evaluation of the current situation of the Commercial Bank of Syria and the mechanism for implementation of its operations and goals to be achieved, through Balanced Scorecard also provides an explanation of the c oncept of Balanced Scorecard in terms of its dependence on four aspects are (financial - customers - internal processes- learning and growth). The study reached the following conclusions: that the bank has succeeded in achieving its objectives in profitability and security of banking, but it did not succeed in satisfying customers, in achieving the goal of improving internal operations, and it did not succeed in achieving learning and innovation in procedures and staff . The research was presented a set of recommendations including: Adoption of the concept of Balanced Scorecard in performance measurement and deepen his understanding of the culture of the bank, the need to focus attention to customers and their proposals and to achieve satisfaction, the need for attention to improving the quality of banking operations and provide services without errors as soon as possible, and to focus attention to human resources at the bank and enable work to increase the degree of employee satisfaction and improve productivity.
The research aims at finding out the role of the electronic banking services provided by the Commercial Bank of Syria in increasing customers' satisfaction, as well as focusing on customers' satisfaction because of its importance and its role in ac hieving the competitive advantage in the delivery of services in the banking sector, which represents an area of competition between public banks and private banks. Also, it aims at stating the extent of the employees' participation in the bank under study regarding their eagerness to achieve customers' satisfaction. At the end, the research presents a summary of the most important findings. It also presents some proposals and recommendations that will further improve the level of electronic banking services and achieving customers' satisfaction inorder to compete at a global level through a field study using a questionnaire designed for this purpose.
The rural roads are a large part of the existing roads network, particularly that consisting of two-lane. Evaluation of traffic performance for two-way, two-lane rural roads is complex process due to their characteristics. Many performance measures were introduced by many authors in many countries to fit the local conditions. This research presents an empirical evaluation of the relationship between operational performance and platooning phenomenon in rural two-lane roads in Tartous. Six performance measures and three platooning variables were defined and calculated for ten study sites using traffic data from rural roads in Ash-Shaykh Badr region of Tartous governorate. Using graphical and statistical analyses, the associations between the performance measures and the platooning variables were examined. The platooning variables investigated, traffic flow in the direction of travel has the highest correlations with performance measures. As the overall findings confirmed that the follower density is the most characterization of the relationship between traffic performance and platooning, which is suitable for the study of operational performance.
This research offers assessment of the urban streets in Lattakia city center. These arterials form main traffic links between major regions. Therefore, Traffic improvement on these streets will have great effect on improving level of service (LOS), increasing speeds, decreasing delay time, decreasing the emissions and traffic accidents. This research was done on six streets surrounding Lattakia city center for defining LOS. Floating vehicle was used in this study. Many trips were executed during free flow and peak periods for measuring free flow speed, Travel time and average speed. Every street was divided into many sections. This study uses field method and computation method adopted by Highway Capacity Manual (HCM2000) for defining LOS on streets and comparing results. This study showed low values of LOS for most sections and it indicated deference between field method and computation method. Also, it expressed the necessary to take suitable procedures to increase LOS on these streets.
The research aims to study the impact of information technology on the quality of banking services in the branches of the Commercial Bank of Syria province of Latakia. To achieve the objectives of the research, a questionnaire was developed and distr ibuted to 201 workers, and (183) questionnaire were suitable to analyze, a response rate (91.04%), and based on applying simple regression to assess the relationship between the information technology and the quality of banking service dimensions, the research found the following results: 1- There is a strong and positive correlation between the hardware equipment and the quality of banking service, where it was found that (79.7%) of the discrepancy in the quality of banking services is explained after the equipment. 2- There is a strong and positive correlation between a online banking service and service quality, it was found that (69.2%) of the discrepancy in the quality of banking services is explained after the Internet. 3- There is a strong and positive correlation between communications and banking service quality, where it was found that (65.9%) of the discrepancy in the quality of banking services is explained after the communication. 4- There are acceptable and positive correlation between post-efficiency of human resources and banking service quality, where it was found that (59.9%) of the discrepancy in the quality of banking services is explained by the efficiency of human resources.
