Unraveling Congestion at the Intersection of the K.H Wahid Hasyim Road - Jalan Gajah Mada: Analysis and Solution

Road intersections play a vital role in the urban traffic system, and with the growth of cities and increasing number of vehicles, they often become the center of congestion. This is due to an imbalance between traffic volume and road capacity, as well as other factors such as short green time and less optimal phase arrangements. Understanding the root causes of congestion is crucial in developing effective solutions.

For example, the intersection of the K.H Wahid Hasyim Road - Jalan Gajah Mada is one of the intersections that experienced traffic density. Studies conducted using the MKJI (Indonesian Road Capacity Manual) and HCM 2000 methods show that this intersection operates at the level of F service with a degree of saturation between 0.826-0.851. That is, the intersection is almost inappropriate to operate and requires a solution to overcome congestion. The need for a comprehensive analysis and solution is evident.

Factors Contributing to Congestion at the Intersection

Several factors contribute to congestion at the intersection of the K.H Wahid Hasyim Road - Jalan Gajah Mada. These factors include:

Effective Width of the Road that is Not Balanced with Traffic Volume

The narrow road causes a long queue and slows down the flow of traffic. The lack of balance between road width and traffic volume is a significant contributor to congestion. A narrow road cannot accommodate the increasing number of vehicles, resulting in a long queue and reduced traffic flow.

Short Green Time

Short green time for each phase causes the vehicle to not be able to cross optimally, resulting in a long queue. The short green time is a major contributor to congestion, as it limits the number of vehicles that can cross the intersection. A longer green time would allow more vehicles to cross the intersection, reducing congestion.

Phase Settings that are Less than Optimal

Inappropriate phase settings can cause traffic conflicts and worsen congestion. The phase settings play a crucial role in determining the flow of traffic. Optimal phase settings can reduce congestion and improve traffic flow.

Solutions to Overcome Congestion at the Intersection

Several solutions can be applied to overcome congestion at the intersection of the K.H Wahid Hasyim Road - Jalan Gajah Mada. These solutions include:

Changes in the Phase or Shape of the Intersection

Adjust the settings of the phase and green time to the existing traffic pattern. For example, considering the addition of phases to increase intersection capacity. Changes in the phase or shape of the intersection can significantly improve traffic flow. By adjusting the phase settings and green time, the intersection can accommodate more vehicles, reducing congestion.

Road Widening

Increasing effective road width to facilitate traffic flow and reduce queues. Road widening is a simple yet effective solution to reduce congestion. By increasing the road width, more vehicles can pass through the intersection, reducing congestion.

Changes in Green Time

Extend green time for a dense phase and adjust it to the volume of traffic on each lane. Changes in green time can significantly improve traffic flow. By extending the green time for a dense phase, more vehicles can cross the intersection, reducing congestion.

Integrating a Solution for a Better Intersection

It is essential to note that the right solution is not always only one. Application of integrated solutions and adjusted to the characteristics of intersections and specific traffic conditions will be more effective. For example, road widening can be combined with phase changes to increase crossing capacity and reduce queues. In addition, it is also necessary to consider technology-based solutions such as intelligent traffic systems (intelligent traffic systems) to optimize traffic arrangements and reduce congestion in real-time.

Conclusion

By analyzing traffic data and applying the right solution, the intersection of the K.H Wahid Hasyim Road - Jalan Gajah Mada can be a more efficient and comfortable intersection for road users. This will have a positive impact on the smooth flow of traffic, the efficiency of travel time, and the level of safety of road users. A comprehensive analysis and solution are essential to overcome congestion at the intersection.
