Traffic Design Solutions for Al Shaheed Road
Summary
Al-Shaheed Road in Amman has a significant volume of traffic throughout the day. Unfortunately, the traffic at this street causes delay and congestion.
The intersections on this street were studied by collecting and analyzing actual data consisting of traffic volumes on each direction of movement on the intersections.
In addition, this study was carried out considering the roundabout of the Al-Mashaghel. Sidra intersection 5.1 software was used for data analysis.
The obtained results were used to describe the level of service of the intersections on this street and to provide possible solutions for the congestion problem.
A number of alternative solutions were considered to minimize delay and congestion.
The analysis showed that Tariq intersection and roundabout of Al-Mashaghel have a traffic problem during peak hours.
Many solutions were proposed and concluded to reduce these problems.
At Tariq signalized intersection, adding new lanes is not possible because the area is completely occupied.
Therefore, the choices of roundabout with a bridge or a tunnel with the roundabout were considered.
The most economical option was the tunnel with the rotor. An attempt was made to re-design the rotor in Al-Mashaghel roundabout.
However, the re-design did not meet the design constraints therefore, the rotor was removed and a traffic signal was designed.
• Design Constraints
| Economical |
- |
| Environmental |
- |
| Social |
Should not be any adverse impact on society in terms of relocation or loss of accessibility. |
| Political |
- |
| Ethical and Safety |

| Other |
The acceptable Level of service (LOS) for all intersection is (D). The acceptable control delay for the Al-Mashaghel roundabout should be between 25-35 (sec/veh.). The acceptable control delay for traffic signal Tariq should be between 35-55 (sec/veh.). |
