Introduction
Capacity is usually defined as: The maximum hourly rate at which persons or vehicles
can reasonably be expected to traverse a point or uniform section of a lane or roadway during
a given time period under prevailing roadway, traffic and control conditions.
The normal function of traffic lights required more slightly control and coordination
to ensure that traffic moves as smoothly and safely as possible and that pedestrians are
protected when they cross the roads. A variety of different control systems are used to
accomplish this, ranging from simple clockwork mechanisms to sophisticated computerized
control and coordination systems that self-adjust to minimize delay to people using the road.
Objectives
- Get familiar write rate of flow in peak hours.
- Learning the synchronize of traffic lights.
- Employing AutoCAD and other engineering programs in the layout.
Data
Part I
Part II First Traffic Intersection
Timing: 5 to 6 Date: 20/12/2015
Counting the number of cars in each direction NS-EW-RL for each signal where we had four
signals in each intersection.
First Traffic Intersection
Timing: 6 to 7 Date: 20/12/2015
Second Traffic Intersection
Timing: 5 to 6 Date: 20/12/2015
Second Traffic Intersection
Timing: 6 to 7 Date: 20/12/2015
Third Traffic Intersection
Timing: 5 to 6 Date: 20/12/2015
Third Traffic Intersection
Timing: 6 to 7 Date: 20/12/2015
Conclusion
Unfortunately, these main intersections in Rak Al Khaimah are not safe for
pedestrians to cross them because there is no specific crossing for them. While these
intersections in the middle of a big population in the area. We noticed that the signals
synchronized depending on the capacity of the streets not in organized way because the town
needs more facilities.
