  5. INTRODUCTION • Transportation Movement of persons and goods over space

  6. Transportation Demand • People and goods do not move for the sake of movement, but to fulfill certain needs. • Mobility must be provided efficiently, by balancing different society needs (cost, convenience, safety, environment protection).

  7. ما هو الفرق بين التصميم الهندسى والانشائي للطريق؟ • التصميم الهندسي:هو التصميم الذي يهتم بتحديد عدد وعرض مسارب الطريق وكذلك تصميم مقاطع الطرق الافقية والرأسية والعرضية. • التصميم الإنشائى:هو التصميم الذي يهتم بتحديد طبقات الرصف المناسبة للطريق وسماكة كل طبقة رصف بما يتناسب مع حجم المرور علي الرصفة وخواص مادة الرصف.

  8. Definition • Speed: Rate of motion(mph, km/hr). There are three types of speed: • Spot speed (سرعة لحظية) It is the instantaneous speed of a vehicle at a specific location. • Running speed The average speed maintained over a given route while the vehicle is in motion. • Average Journey Speed Distance traveled divided by the total time taken to complete the distance.

  9. Definition • Volume, Flow: The total number of vehicles that pass over a given point of high way during specific time interval. • Rate of flow: the equivalent hourly rate at which vehicles pass over a given point of highway during given time period less than 1hour, usually 15min

  10. Definition • Peak hour factor (PHF): the ratio of total hourly volume to the maximum 15-minute rate of flow within the hour. • PHF (minimum) = 0.25 ( V = Vكل المركبات تمر في ربع ساعة 15) • PHF (maximum) = 1 ( V=4V15المركبات موزعة علي الأرباع بالتساوي ( Steady flow.

  11. Example: • The following traffic counts were made during an hour-long study period: Answer: The hourly volume = 1000+1200+1100+1000 = 4300 veh The rates of low = [ No. of veh.] / [time(in hours)]

  12. Definition • Density, concentration: (K,D): the number of vehicles occupying a given length of highway at a given instant. (Veh/km). عدد السيارات الموجودة في طول معين من الشارع في لحظة معينة

  13. LOS • Level of Service: LOS is a qualitative measure that describes operational conditions within a trafficstream and their perception by drivers or / and passengers. • Level of service has six levels, the first one is A, and the worst one is F.

  14. ADT VS AADT • ADT (average daily traffic): the average of 24hour counts collected over a number of days greaterthan 1day and less than 1-year مجموع السيارات خلال عدة أيام أقل من سنة / عدد هذه الأيام • AADT (average annual daily traffic): the average of 24-hour counts collected over a year. It is used to: 1- Study The accidents and obstacles. 2- Design and evaluation of highway. 3- Study the benefits that may come from the road.

  15. Number of Lanes
