Traffic Analysis of the Needs of the Overpass at the Intersection (Case Study: Simpang Jl. Gatot Subroto-Jl. Sunggal-Jl. Muslim Captain)

Introduction

Medan City, the economic and trade center of North Sumatra, has experienced significant growth in vehicle numbers. This increase has led to frequent traffic jams, especially during rush hours, causing stress for motorists and economic losses due to lost time and increased operational costs of vehicles. To overcome this problem, the authors analyzed the needs of the construction of the overpass at Simpang Jl. Gatot Subroto-Jl. Sunggal-Jl. Muslim Captain, a meeting point of three main roads with high traffic volume.

Existing Conditions and Intersection Performance

The existing traffic characteristics at the intersection show a degree of saturation of 0.89, an average intersection time of 60.66 seconds, and a level of service F. This indicates that the intersection is very dense and has a poor service level. Improvements made through the addition of the approach and the manufacture of the left turn lane directly can only improve the performance of the intersection to D, with a degree of saturation of 0.77 and an average intersection time of 29.75 seconds. The traffic volume that passed the intersection reached 20,699 vehicles per day on Jl. Gatot Subroto and 11,146 vehicles per day on Jl. Muslim Captain.

The Importance of Understanding Existing Conditions

Understanding the existing conditions of the intersection is crucial in determining the needs of the overpass construction. The degree of saturation, average intersection time, and level of service are key indicators of the performance of the intersection. In this case, the existing conditions show that the intersection is very dense and has a poor service level, indicating a need for improvement.

Feasibility Study and Recommendations for Construction of Flying Roads

Based on the results of the feasibility study of the Development of the Fly Over of the North North Arteri Road (Package-7) in the Province of D.I Yogyakarta, the construction of the overpass is appropriate with the average daily traffic volume (LHR) above 20,000 vehicles. The author then analyzes three alternative scenarios in the construction of the overpass at Simpang Jl. Gatot Subroto-Jl. Sunggal-Jl. Muslim Captain. The recommendation given is the construction of the overpass according to scenario 1, which produces a degree of saturation of 0.57, an average intersection time of 15.01 seconds, and a service level B. This scenario also includes the addition of the left turn lane directly (Ltor) to the mouth of the West intersection.

The Benefits of a Feasibility Study

A feasibility study is essential in determining the viability of a project, including the construction of the overpass. In this case, the study shows that the construction of the overpass is appropriate with the average daily traffic volume above 20,000 vehicles. This indicates that the project is feasible and can provide significant benefits.

Conclusions and Benefits of Overpass Construction

Based on the analysis, the construction of the overpass at Simpang Jl. Gatot Subroto-Jl. Sunggal-Jl. Muslim Captain is needed to improve the performance of the intersection and overcome congestion. The overpass will provide significant benefits, including:

*** Increase road capacity and reduce congestion. *** *** Streamlining the flow of traffic, especially during rush hours. *** *** Lowering the travel time and operational costs of vehicles. *** *** Improve the safety and comfort of driving. **

The Importance of Overpass Construction

The construction of the overpass is crucial in improving the performance of the intersection and overcoming congestion. The benefits of overpass construction are numerous, including increasing road capacity, streamlining traffic flow, lowering travel time and operational costs, and improving safety and comfort of driving.

Recommendations for Future Research

Based on the analysis, the following recommendations are made for future research:

Analyze the feasibility of the overpass construction, including the average daily traffic volume and the potential benefits of the project.
Develop a detailed design for the overpass construction, including the layout, materials, and construction methods.
Conduct a cost-benefit analysis of the overpass construction, including the costs of construction, maintenance, and operation.

The Importance of Future Research

Future research is essential in providing a comprehensive understanding of the needs of the overpass construction and the potential benefits of the project. The recommendations made above will provide a foundation for future research and ensure that the overpass construction is a success.

Conclusion

In conclusion, the construction of the overpass at Simpang Jl. Gatot Subroto-Jl. Sunggal-Jl. Muslim Captain is needed to improve the performance of the intersection and overcome congestion. The overpass will provide significant benefits, including increasing road capacity, streamlining traffic flow, lowering travel time and operational costs, and improving safety and comfort of driving. The development of this overpass infrastructure needs serious attention from the government and related parties. In addition to providing long-term solutions to congestion problems, overpass construction is also an investment that has the potential to increase economic growth in the city of Medan.
