      تاريخ الامتحان: الاثنين 15/4/2024

      الامتحان من جزئين:الوقت الكلي للامتحان 90 دقيقة (مع استراحة 5 دقائق بين الجزئين)

       

      1.     الجزء الأول هو عبارة عن اسئلة اختيار من متعدد (22 سؤال)، يبدأ وقته الساعة 14:00  ويستمر لمدة 40 دقيقة (14:00 – 14:40) ومخصص له 44 علامة.


      2.     كما تعودتم، بخصوص أسئلة الجزء الأول ستظهر ترتيب الأسئلة عشوائية لكل طالب وستكون خيارات الإجابة لكل سؤال مخلوطة ومختلفة من طالب إلى آخر.


      3.     في الجزء الأول سيظهر للطالب سؤالين في كل صفحة، تأكد من الإجابة على كل سؤال منهما، ومن ثم الانتقال إلى الصفحة التالية. وفي حال الانتقال إلى الصفحة التالية، لا يمكن العودة إلى الصفحة السابقة.


      4.     في الجزء الأول يتفاوت الوقت اللازم للإجابة على كل سؤال، بعضها سريع (يلزمه أقل من دقيقة) والآخر قد يستغرق وقتا أطول، متوسط الوقت اللازم للإجابة على كل سؤال منها هو 1.5 دقيقة. لذلك على كل طالب إدارة وقته بحكمه. العديد من الأسئلة يمكن الإجابة عليها دون الرجوع إلى المادة المطبوعة أو الاكترونية، وهذا هو المتوقع من الطالب، لذلك استغل الوقت بحكمه.


      5.     بعد الجزء الأول، استراحة لمدة 5 دقائق  (14:45 – 14:40) 


      6.     الجزء الثاني يبدأ الساعة 14:55 وهو عبارة عن 3 أسئلة حل ذات إجابات محددة وبعضها قصيرة، ويستمر لمدة 50 دقيقة (14:55 – 15:45) ومخصص له 60 علامة.

      1. Demonstrate the purposes, objectives and major characteristics of traffic control systems.
      2. Identify the different types of traffic control devices.
      3. Illustrate the types of conflicts among traffic streams at intersections.
      4. Explain the types of intersection control and illustrate the warrants for adopting each.
      5. Illustrate the principles of the design of traffic signal systems.
      6. Apply the principles of the design of traffic signal systems to isolated at-grade intersections.
