Abstract

Roads are a fundamental component of transportation that plays a critical role in national economic growth. Maintaining road conditions is essential to ensure optimal traffic serviceability. However, in developing countries like Indonesia, these surveys are predominantly conducted manually. This conventional approach is time-consuming, costly, and requires a substantial amount of human resources. The swift progression of machine learning (ML) within Artificial Intelligence (AI) presents an opportunity to be utilized as a data processing tool for road condition surveys, leading to greater time and cost efficiency. This study analyzes the cost and time required for two survey methods: manual and semi-automated, employing machine learning. Based on the analysis conducted on 164 km of urban roads in Bandung City, the semi-automated ML method achieved a cost efficiency of 72.23%, with its total cost being only 27.77% of the manual method. Furthermore, the time efficiency reached 96.34%, meaning the survey was completed in just 3.66% of the time required by the manual approach. These results indicate that the application of machine learning for semi-automated road condition surveys is substantially more efficient in terms of both time and cost compared to traditional manual surveys.

Abstract

Abstract The problem of traffic congestion and the high risk of accidents at level crossings between railways and public roads in Bandung City requires urgent handling of these crossings. Ideally, the existence of these level crossings should be eliminated, to ensure the railway safety and the safety and smooth flow of traffic on public roads. Although handling level crossings to non-level crossings is a needed solution, its implementation requires high costs. Therefore, an objective analysis is needed to determine the level crossings that really need to be prioritized for handling. In this study, the handling of these level crossings is examined, using Multi-Criteria Analysis that integrates technical and non-technical aspects as determining parameters. This study shows that the level crossing on Jln. Laswi obtained the highest score, with a total score of 46.50, followed by the level crossing on Jln. Gedebage Selatan and the level crossing on Jln. A. Yani, with total scores of 42.50 and 39.00, respectively. Based on these results, it is recommended that these three level crossings be upgraded to non-level crossings. Keywords: level crossing; railroad; road; traffic congestion; traffic safety Abstrak Permasalahan kemacetan lalu lintas dan tingginya risiko kecelakaan pada perlintasan sebidang antara jalan rel dan jalan umum di Kota Bandung menuntut adanya penanganan yang mendesak terhadap perlintasan tersebut. Idealnya, keberadaan perlintasan sebidang ini ditiadakan, untuk menjamin keselamatan perjalanan kereta api serta keselamatan dan kelancaran arus lalu lintas di jalan umum. Meskipun penanganan perlintasan sebidang menjadi perlintasan tidak sebidang merupakan solusi yang dibutuhkan, implementasinya memerlukan biaya yang tinggi. Karena itu, perlu dilakukan analisis yang objektif sehingga dapat ditentukan perlintasan-perlintasan sebidang yang memang perlu mendapat prioritas untuk ditangani. Pada studi ini dikaji penanganan perlintasan sebidang tersebut, dengan menggunakan Multi-Criteria Analysis yang mengintegrasikan aspek teknis dan aspek nonteknis sebagai parameter penentu. Studi ini menunjukkan bahwa perlintasan sebidang di Jln. Laswi memperoleh skor tertinggi, dengan nilai total 46,50, diikuti oleh perlintasan sebidang di Jln. Gedebage Selatan dan perlintasan sebidang di Jln. A. Yani, yang masing-masing bernilai total 42,50 dan 39,00. Berdasarkan hasil tersebut, ketiga perlintasan sebidang ini direkomendasikan untuk ditangani menjadi perlintasan tidak sebidang.
