يشكل تقييم سعة التقاطعات المنظمة بإشارات ضوئية أحد أهم الأسس المستخدمة في تخطيط و تصميم و تشغيل و إدارة شبكة الشوارع في المدن، و يعتمد حساب السعة على تقدير قيمة غزارة الإشباع على التقاطعات المنظمة بإشارات ضوئية. يتم استخدام طريقة دليل سعة الطرق السريعة الأمريكي (HCM2010) في تقدير و تحليل غزارة الإشباع، و هذه الطريقة مستخدمة بشكل واسع في دول العالم و منها سوريا، و لكن هذا الدليل يعبر عن الظروف المحلية في الولايات المتحدة الأمريكية، و لذلك قد لا يكون مناسباً لاستخدامه في ظروفنا المحلية. يتناول هذا البحث تقدير غزارة الإشباع حقلياً بالاعتماد على الفواصل بين العربات ضمن الأرتال، و مقارنة النتائج الحقلية لغزارة الإشباع مع القيم الناتجة عن استخدام طريقة HCM. تم اجراء الدراسة على ثلاث تقاطعات في مدينة طرطوس، و استند التحليل على تجميع البيانات باستخدام الفيديو. أكدت النتائج النهائية أن هناك اختلاف بين القيمة الحقلية لغزارة الإشباع و القيمة الحسابية، مما يؤكد عدم امكانية استخدامها لظروفنا المحلية.
The evaluation of the capacity of signalized intersections is one of the most important parameter used in the planning, design, operation and management of urban street networks. The calculation of capacity depends on the estimation of the saturation flow of the signalized intersections. The highway Capacity Manual (HCM 2010) is used to estimate and analyze the saturation flow. This method is widely used in many countries around the world, including Syria. It reflects the local conditions in the United States of America; therefore it may not be suitable for use in our local conditions. This study includes estimation of the field saturation flow depending on the headways between the vehicles in the queues, and comparing the field results of the saturation flow with the values resulting from using the HCM. The study was conducted on three intersections in the Tartous city. The analysis was based on data collection using video. The final results confirmed that there is a clear difference between the field measurement of the saturation flow and computation value, Which confirms that it cannot be used for our local conditions.

Evaluation of present and future traffic situation is carried out for estimating the level of service through a lot of traffic indicators (such as Saturation Flow, capacity, delay and travel time), but all these indicators are based primarily on the
measurement of Passenger Car Unit (PCU) .This paper analyzes the impacts of
four different types of vehicles on the capacity of signalized intersections. Data was collected at five intersections in Damascus city, and estimates of mean headways associated with four different types of vehicles, as well as passenger cars. Using the estimated headways, Passenger Car Equivalents (PCEs) were
calculated, and these suggest that the impacts of these types should be given special consideration when analyzing the capacity of signalized intersections.
Low frequency shadows is one of hydrocarbons indicators. It can be
detected by means of a time-frequency decomposition which can provide higher
frequency resolution at lower frequencies and higher time resolution at higher
frequencies. This is des
irable for analyzing seismic data, because the
hydrocarbons in reservoir are diagnostic at lower frequencies. we have carried
out such analyses with post-stack data sets on Fahda field which is located in
Aleppo uplift, it contains oil. Adding a frequency axis to a 2D seismic section
makes the data 3D axis. The comparison of the single frequency sections from
such 3D volume can be utilized to detect low frequency shadows. A
preferentially illuminated single frequency section at lower frequencies from
Fahda field, shows high amplitude low frequency anomalies beneath oil zones.
These anomalies disappear at higher frequencies.
This research focuses on optimising the traffic control at ( Al-
TARBYA) signalised intersection in Homs city to improve its
capacity and the Level Of Service (LOS).
The importance of this research comes from analysing the
movement of vehicles, p
edestrians, the intersection geometry, signal
phasing plan on the intersection, and referring to some problems
affects the intersection in order to get the best improvement to
traffic movement at the aforementioned intersection.

Bridges are important and vital structures that provide communication between
different regions. Due to their importance, their design has had a great attention throughout
the world, as evidenced by the continuous development of seismic design code
s such as
AASHTO, which now adopts the performance-based design, and requires through a set of
requirements and criteria that the bridge performance under the design earthquake is at life
safety (LS) level and thus ensures that it does not collapse. Since most of the local bridges
were built at periods where these criteria were not adopted, it is important to verify their
performance and that they meet these criteria.
In this paper, the seismic performance of an existing bridge, which represents a model
for a wide range of local multi-span simply supported bridges, was evaluated by
developing a 3D model of the bridge using SAP2000V19.1 and applying the nonlinear
static analysis. The results of analysis have been used to verify that the bridge meets the
AASHTO seismic requirements, which include the check of the P-Δ requirement,
displacement demand/ capacity, members (columns) ductility, as well as the check of the
shear demand/capacity of the columns.
The results showed that the performance of the studied bridge under the seismic
intensities adopted in the Syrian code achives the acceptable level which is life safity (LS),
but it exceeds this level under high seismic intensity. The research also showed that there is
compatibility between the results of nonlinear static analysis and AASHTO requirements.
