Introduction

Determining the shortest route is a crucial aspect in increasing the efficiency of transportation costs, and it is a very interesting issue to discuss. The shortest route can be interpreted as a minimum distance that needs to be taken from source to destination. To solve this problem, the author uses a graph approach. The Ant Colony Optimization (ACO) algorithm is a heuristic algorithm inspired by the behavior of ant colonies, which has been proven effective in finding solutions to the shortest route determination problem. One of the advantages of the ACO algorithm is its ability to be applied in various non-polynomial problems (NP) (Dorigo et al., 2006).

Limitations of Traditional ACO Algorithm

However, in traditional ACO, the process of determining the path is carried out randomly, with a weight that is only calculated based on distance. This does not fully reflect on real conditions, because each path in the real world has different characteristics. For example, the road that is traversed may have a narrow size, which can cause congestion, or there is a potholes. Therefore, the calculation of the path must consider other factors that can affect the smooth running of the trip.

Modification of ACO Algorithm

In an effort to overcome this problem, various studies have been conducted that discuss the modification of the ACO algorithm. One significant modification is to integrate the decision support system (SPK) to the algorithm, especially by adding a simple multi-attribute rating technique (SMART) algorithm. In this approach, the weight used for the selection of paths between points (nodes) is not only based on distance, but also considers various other attributes such as congestion levels, road conditions, road priorities, and other features.

Benefits of Modified ACO Algorithm

Modification of the ACO algorithm that combines the SPK system with SMART brings a number of significant benefits. First, taking into account various additional factors, algorithms can produce more optimal and realistic routes. Drivers or those who use this system not only get information about the shortest route in terms of distance, but also routes that are faster and safer to pass.

Second, the integration of some attributes in determining the weight helps in making better decisions, especially in situations where there are road choices that look the same in terms of distance. For example, if there are two routes that have almost the same distance, but one route experiences a significant congestion, this algorithm is able to assess and choose a more efficient route based on available congestion data.

Third, the use of the SMART algorithm in ACO can also increase the accuracy of the path prediction to be taken, taking into account the actual conditions of the road. For example, a road that often has holes or has many red lights will have a higher weight in assessment and can be avoided if other alternative routes are available.

Real-World Applications

Thus, the modification of the ACO algorithm using the SPK and SMART approach not only increases effectiveness in determining the shortest route but also provides additional benefits oriented and user safety. This is very relevant given the faster development of information technology and the need for an efficient and responsive transportation system for real-time conditions. With the integration of this technology, we can hope that future transportation systems will be smarter and well integrated to provide the best solution for the community.

Future Research Directions

Future research directions can focus on further improving the accuracy of the modified ACO algorithm by incorporating more attributes and data sources. Additionally, the development of a user-friendly interface for the system can also be explored to make it more accessible to the general public. Furthermore, the integration of other optimization techniques, such as genetic algorithms or simulated annealing, can also be investigated to further improve the performance of the system.

Conclusion

In conclusion, the modification of the ACO algorithm using the SPK and SMART approach is a significant improvement over traditional ACO algorithms. The integration of additional attributes and data sources can provide more accurate and realistic routes, making it a valuable tool for transportation systems. With the continued development of information technology, we can expect to see more advanced and efficient transportation systems in the future.
