تعتبر الرياض من اكثر المدن ازدحاما

تعتبر الرياض من اكثر المدن ازدحاما بالحركة المرورية في الوطن العربي , لما تشهده من تطور في البنية التحتية والعمرانية والنمو الاقتصادي مما ادى الى زيادة الطلب على النقل, فلذلك وجب التدخل للحد من مشكلة الازدحام المروري بتنفيذ مشروع قطار الرياض وهذا بدوره سوف يحد من مشكلة الازدحامات المرورية ولكن تحتاج المدينة لتطبيق أنظمة النقل الذكي في شبكات الطرق للمدينة, وأحد انواع هذا النظام هو التحكم بمداخل الخطوط السرعة (قياس المنحدر) حيث يقوم بالتحكم بدخول المركبات للخطوط السريعة التي تعتبر من اهم الاسباب في مشكال الازدحام المروري ولذلك يتم عمل اشارة مرورية في مدخل الطريق السريع ويتم التحكم بها بعده طرق مختلفة, وقد طبق هذا النظام في امريكا واوروبا وشرق اسيا وكان له التاثير البالغ في التقليل من حدة الازدحام المروري وخاصة في اوقات الذروة.
لذلك هذه الدراسة سوف تقوم بتطبيق نظام (منحدر القياس) في احد الطرق السريعة لمدينة الرياض التي تعاني من الازدحام المتكرر خلال اليوم عن طريق برامج المحاكاة للحركة المرورية . حيث سيتم تحديد منطقة الدراسة بناءً على معايير محددة , وسوف تُجمع البيانات من منطقة الدراسة ويتم تحليلها وادخالها الى برنامج المحاكاة حيث تتم معايرة المعاملات المتعلقة بسلوك السائقين وطبيعة منطقة الدراسة لتوافق البيانات المأخوذة من الواقع وبعدها نقوم بعمل عدة سيناريوهات لتطبيق النظام والحصول على افضل اداء.
سوف تخلص الدراسة الى تقييم شامل لمدى كفاءة وفعالية هذا النظام في مدينة الرياض بمقارنة الوضع الحالي للطريق مع الوضع بعد تطبيق هذا النظام والذي بدوره سوف يعطي رؤية لمتخذي القرار في المدينة اوالجهات المسؤلة لأستخدام النظام من عدمه.

Riyadh is more populous cities traffic in the Arab world, to the evolution of the physical infrastructure and economic growth leading to increased demand for transport, so I had to intervene to reduce the problem of traffic congestion in Riyadh train project which in turn will reduce traffic congestion problem but want the city to implement intelligent transport systems in the city's road networks, one species of this order is the font entries control speed (measure slope) to control vehicle access to motorways, which are The most important reasons in a kaleidoscope of traffic congestion so is traffic signal at the entrance to the highway and is controlled in several different ways, this system has been applied in America, Europe and East Asia and has had a great impact in reducing traffic congestion, especially at peak times.Therefore this study will apply the system (measurement slope) in a highway of Riyadh city beset by frequent congestion during the day through simulations of traffic. Where you will identify the study area based on specific criteria, and will collect data from the study area and analyzed and entered into the Simulator be calibrated transactions involving the behavior of drivers and nature study area data from consensus reality and then doing a few scenarios for implementing the system and get the best performance.You will study concludes a comprehensive assessment of the efficiency and effectiveness of that system in Riyadh by comparing the current situation for path with mode after applying this system which in turn will give vision for decision makers in the city awalghat in charge of using the system.

Riyadh is one of the most busiest cities traffic movement in the Arab world, when seen from the development of the infrastructure and urban infrastructure and economic growth, leading to increased demand for transportation, therefore must intervene to reduce the problem of traffic congestion is implementing a project Riyadh train and this in turn will limit the problem of traffic jams but the city 's need for the application of intelligent transport systems in the road network of the city, and one of the types of this system is the entrances lines Speed control (measuring the slope) which is controlling the entry of vehicles fast lines which is one of the most important reasons in the kaleidoscope of traffic congestion and so does the work of a traffic signal at the entrance to the highway and is controlled in several different ways, this system has been applied in America, Europe and East Asia , and has had a deep impact in alleviating the traffic congestion, especially at peak times.
Therefore , this study will apply the system (ramp metering) on a highway to the city of Riyadh , which suffers from frequent congestion during the day by simulation of traffic programs. Where it will determine the study area based on specific criteria, and will combine the data from the study area it is analyzed and entered into the simulation software , where it is calibrated transactions relating to the behavior of drivers and the nature of the study area to consensus data from reality and then we work several scenarios for the application of the system and get the best performance.
The study will conclude a comprehensive assessment of the efficiency and effectiveness of the system in the city of Riyadh comparing the current situation of the road with the situation after the application of this system, which in turn will give a vision for decision - makers in the city Awaljhat Responsible to use the system or not.
