Abstract

Crash cost is an important component for conducting economic analysis in selecting countermeasures for crash locations. It is used to convert the benefit of crash or fatality reduction into monetary terms. Many research on crash cost have been carried out in Indonesia. Most of the research utilized gross output/human capital approach. However, this approach has been widely criticized for not being able to describe the quality of life of crash casualties and the costs of pain, grief and suffering (i.e. human cost). The concept of Value of Statistical Life  (VoSL) has been introduced by InDeV (2016) to calculate the human cost, which is assessed by using willingness to pay approach. To obtain a more reliable estimation of crash cost for Indonesia, it is necessary to conduct a study on crash cost involving motorcycles which incorporates the estimation of human cost. The VoSL is obtained by interviewing motorcycle users for willingness to pay with safety equipment. Based on the analysis, it is obtained that the value of statistical life (VoSL) for fatality in a road crash was estimated to be Rp.2.3 billion. The unit cost of fatal injury is Rp.3.08 billion, serious injury is Rp.333 million and slight injury is Rp.24.9 million. The unit cost of fatal crash on arterial roads is Rp.3.23 billion, serious crash is Rp.451 million and the slight crash is Rp.114 million. The unit cost of fatal crash on collector roads is Rp.3.16 billion, serious crashes is Rp.381 million and minor crash is Rp.69.4 million. The unit cost of fatal crash on local roads is Rp.3.09 billion, serious crash is Rp.338 million, and minor crash is Rp.29.8 million. Keywords: Motorcycle crash cost, gross output approach, human capital approach, willingness to pay approach

Abstract

Abstrak: Sektor transportasi merupakan salah satu penyumbang emisi gas rumah kaca yang besar saat ini, dan menjadi tantangan besar di abad 21, khususnya dalam pengembangan pembangunan transportasi yang berkelanjutan. Inventori emisi merupakan salah satu alat yang dapat digunakan sebagai dasar pengambilan keputusan dalam permasalahan pencemaran udara. Baseline emisi dihitung di beberapa titik akurat pada jalan, yang paralel dengan proyek BIUTR. Penelitian ini dilakukan di 7 ruas jalan dalam koridor Pasteur-Cileunyi dan Ujungberung-Gedebade, untuk gas rumah kaca (CO2 dan HC), dan pencemar udara lainnya (CO, NOx, dan PM10) dari sektor transportasi. Faktor emisi Inggris dignakan dalam perhitungan beban emisi karena lebih detail dan sesuai dengan kondisi di lapangan (ragam kecepatan dan jenis kendaraan). Hasil menunjukkan skenario proyek BIUTR meningkatkan beban emisi, berkaitan dengan meningkatnya volume kendaraan. Peningkatan beban emisi yang dihitung untuk proyeksi tahun 2015-2030 dari beban emisi driving adalah (34,9 - 152,13)%, (100,94 - 441,74)%, (17,53 - 70,51)%, (12,83 - 55,5)%, dan (16,65 - 70,87) %, untuk CO2, NOx, PM10, CO, dan HC, secara berurutan. Kata kunci: Baseline emisi, transportasi berkelanjutan, pencemar udara, faktor emisi Abstract : Transportation sector as one of the biggest contributors of greenhouse gas emission, becoming one of the biggest challenges in the 21st century; especially on the way people build a sustainable transportation system. Inventory emission is one of the tools that is commonly be used as a foundation tool for decision makers in managing pollution problems. Emission baseline is calculated in some precisely exact points on the road, parallel with BIUTR project which plans to the extend to the existing and put some new fly over road links. This research was done in 7 lines of roads within the route between Pasteur-Cileunyi and Ujungberung-Gedebage. The research is focused on greenhouse gases, of CO2 and HC, and air pollutants (CO, NOx, and PM10) focusing on transportation as the source. British emission factor was used because it is the best implicated emission factors as it is better in details and the field condition, e.g. various speed and vehicle type. The results shows that BIUTR project scenario increases emission load, related to the increase of vehicles volume. The increase of emission calculated for 2015-2030 from driving emission load are (34,9 - 152,13)%, (100,94 - 441,74)%, (17,53 - 70,51)%, (12,83 - 55,5)%, and (16,65 - 70,87) %, for CO2, NOx, PM10, CO, and HC, respectively.Key words: Emission baseline, sustainable transportation, air pollutant, emission factor

Abstract

The majority of runways are constructed using flexible pavement surfaced with Hot Mix Asphalt (HMA). The performance of these materials is significantly influenced by temperature due to their viscoelastic nature. Understanding the maximum temperature profile in the HMA layer is essential for evaluating pavement load-bearing capacity and durability. Therefore, this study aimed to present a robust model for predicting maximum pavement temperature distributions based on direct measurements from 13 strategically selected airports in the tropical region of Indonesia. Data was collected using the Airside Pavement Sensing System (AirPaSS), a monitoring device that integrated solar-powered energy management, automated data transmission, and multi-depth thermocouple sensors, providing real-time and accurate temperature measurements. By using hierarchical clustering, airports were categorized into three clusters based on air temperature, pavement temperature, and elevation, enabling precise and cluster-specific material design. The result showed that the predictive model incorporating linear and logarithmic regression achieved high accuracy, with Root Mean Squared Error (RMSE) values ranging from 0.91°C to 2.01°C and Adjusted R² values between 0.76-0.91. This model offered a practical solution for predicting HMA layer temperature at any depth. The results provided valuable information for performance-based grading systems with significant implications for improving infrastructure resilience in tropical and similar climatic regions. Doi: 10.28991/CEJ-2025-011-03-01 Full Text: PDF

Abstract

This study aims to evaluate the accuracy of IRI prediction using the MEPDG 2015 method with two different local calibration parameters—New Mexico and Virginia—by comparing them against actual field conditions in Indonesia. The analysis was conducted on six segments of the North Coast National Road (Pantura), totaling 55.87 km, using input data from 2020 and field measurements from 2021 to 2023. Pavement responses were analyzed using ELMOD 6 and KENPAVE, and predictions were made for rutting, fatigue cracking, and IRI. The results showed that MEPDG 2015 with Virginia calibration produced the smallest relative deviation (?15.66%) compared to the field data, indicating better alignment with actual pavement performance than the New Mexico calibration. The findings confirm the importance of selecting calibration parameters appropriate to local climate and structural conditions. MEPDG 2015 with Virginia calibration is recommended for future IRI prediction in areas with similar environmental characteristics to western Indonesia.

Abstract

Road maintenance, as an effort to maintain its performance, plays a crucial role in a road network management system. However, insufficient resources and differences in how stakholders perceive this issue pose challenges in the process of programming road maintenance. This study aims to develop a road maintenance prioritization model based on the Analytical Hierarchy Process (AHP) for the road network under the authority of the Jambi City Government. The AHP-based weighting is conducted based on a hierarchical decision-making model for road maintenance, which consists of three main criteria: technical road conditions, socio-economic factors, and connectivity, along with their respective sub-criteria. The results of the study show that in the main criterion, road technical conditions weighted the highest of all with a value of 0,65. Followed by connectivity at 0,19 and socio-economic at 0,16. Then regarding the sub-criterion, the highest global weight is road damage level, with a value of 0,28. The model developed in this study is expected to be used as a decision-making support tools to program road maintenance. The multi-criteria assesment which was conducted is expected to evaluate road priority level holistically and provide a new perspective in decision-making.

Abstract

Mass rapid transit (MRT), inaugurated in 2019 by the DKI Jakarta Provincial Government, was designed to address the city's transportation challenges by improving accessibility and reducing spatial disparities. This study assessed the MRT’s impact on accessibility and spatial equity, specifically regarding travel time, economic potential, and travel fares. Primary data was collected through a questionnaire to identify passengers' origins and destinations, which was used to analyze the catchment area and calculate real-time travel times during peak hours via a navigation application. Secondary data helped calculate accessibility and spatial equity for two scenarios: with and without the MRT. GIS (Geographic Information System) was used to facilitate a visual understanding of the findings. The analysis revealed that while the MRT improved overall accessibility regarding travel time and economic potential, it failed to reduce travel fares, which are higher than those of other public transportation options like Jaklingko, TransJakarta, and KRL. Moreover, the MRT operation worsened spatial disparities, increasing the gap in accessibility between different areas of the city. In conclusion, while MRT has succeeded in enhancing travel efficiency and boosting the economic potential of several regions, it has also highlighted a growing spatial inequality, particularly regarding travel fares, which remain a challenge for equitable access to transportation across Jakarta.

Abstract

Abstrak Penelitian ini bertujuan membandingkan akurasi metode prediksi kondisi jalan antara MEPDG 2015 dan IRMS V.3 sebagai dasar pemrograman preservasi jalan pada skala jaringan. Studi dilakukan pada enam ruas jalan nasional Pantura sepanjang 55,87 km dengan karakteristik lalu lintas beragam. Prediksi IRI metode MEPDG 2015 dihitung menggunakan pendekatan mekanistik-empiris dengan tiga jenis kalibrasi (Global, Arizona, dan Oregon), serta bantuan software ELMOD 6 dan KENPAVE. IRMS V.3 menggunakan pendekatan empiris berbasis data historis. Hasil prediksi dibandingkan dengan data aktual tahun 2021–2023 untuk menghitung deviasi relatif, kemudian dianalisis dalam program preservasi selama 20 tahun dengan dua skenario: unconstrained budget dan constrained budget menggunakan Back-fall Strategy (strategi menunda, bertahap, dan holding). MEPDG 2015 kalibrasi Oregon menunjukkan deviasi relatif terkecil (−15,48%) dan merupakan metode paling akurat. Dalam kondisi tanpa batasan anggaran, metode ini lebih hemat dibanding IRMS V.3. Dalam keterbatasan anggaran, strategi holding dengan MEPDG 2015 menghasilkan kemantapan jalan akhir 2–3 kali lebih tinggi bila dibandingkan dengan strategi lain, meskipun biayanya 1–2% lebih besar. Dengan demikian, MEPDG 2015 kalibrasi lokal Oregon dengan strategi holding direkomendasikan sebagai strategi terbaik saat terjadi keterbatasan anggaran di skala jaringan. Kata-kata Kunci: Back-fall strategy, IRMS V.3, MEPDG 2015, preservasi. Abstract This study aims to compare the accuracy of road condition prediction methods between MEPDG 2015 and IRMS V.3 as a basis for network-level road preservation programming. The study was conducted on six continuous segments of the Pantura national road spanning 55.87 km with varying traffic characteristics. IRI prediction using the MEPDG 2015 method was calculated based on a mechanistic-empirical approach with three calibration types (Global, Arizona, and Oregon), supported by ELMOD 6 and KENPAVE software. Meanwhile, IRMS V.3 applies an empirical approach based on historical data. The prediction results were compared with actual field data from 2021–2023 to calculate relative deviation and analyzed in a 20-year preservation program under two budget scenarios: unconstrained and constrained budget using the Back-fall Strategy (postponed, gradual, and holding strategies). MEPDG 2015 with Oregon calibration showed the smallest relative deviation (−15.48%) and was the most accurate method. Under an unconstrained budget, it was also more cost-efficient than IRMS V.3. Under budget constraints, the holding strategy with MEPDG 2015 produced 2–3 times higher final road condition performance when compared to other strategies, despite requiring 1–2% more cost. Therefore, MEPDG 2015 with local Oregon calibration and holding strategy is recommended as the best option under limited budget conditions at the network level. Keywords: Back-fall strategy, IRMS V.3, MEPDG 2015, preservation.

Abstract

Abstract Studies on the travelers’ perceptions to toll roads during the ramp-up period are still rare, whereas they are important to assess toll road investment. The paper aims to establish a first approach in modeling the perceptions of individual commuter travelers during the learning process and adaptation to newly operating toll roads. Particularly, efforts to identify the attitudes and behaviors of individual commuter travelers towards interurban toll roads that connect between developing agglomeration areas. The data is collected through revealed and stated preference surveys using a snowball sampling technique with social media applications. Then we develop a binary logit model to explore commuter travelers’ perceptions to toll road during ramp-up period, and the results indicate that when doing commuter travel activities prefer to use the toll road, with the attributes that most influence on decision making respectively, travel time, travel costs, toll gate distance, travel distance, traveler's age, scenic beauty and the frequency of using toll roads. The paper also showed that the positive preference of toll roads during the ramp-up period is not always related to traffic congestion such as in dense urban areas, the presence of sightseeing traffic is very potential. Keywords: Route choice behavior, binary logit model, toll road, ramp-up period Abstrak Studi mengenai persepsi masyarakat terhadap jalan tol selama periode ramp-up masih jarang dilakukan, hal ini penting untuk menilai kelayakan investasinya. Makalah ini bertujuan untuk menetapkan pendekatan pertama dalam memodelkan persepsi individu pelaku perjalanan komuter selama periode tersebut sebagai proses belajar dan beradaptasi terhadap jalan tol yang baru beroperasi. Khususnya, upaya untuk mengidentifikasi sikap dan perilaku individu pelaku perjalanan terhadap jalan tol antar kota penghubung kawasan aglomerasi yang sedang berkembang. Pengumpulan data dilakukan melalui survei revealed dan stated preference dengan teknik bola salju (snowball sampling) yang menggunakan media sosial. Kemudian kami mengembangkan model logit-biner untuk mengeksplorasi persepsi penumpang komuter terhadap jalan tol pada periode ramp-up dan hasilnya menunjukkan bahwa ketika melakukan aktivitas perjalanan, pelaku perjalanan komuter lebih memilih menggunakan jalan tol dengan atribut yang paling berpengaruh terhadap pengambilan keputusan masing-masing adalah, waktu tempuh, biaya perjalanan, jarak gerbang tol, jarak tempuh, umur penumpang, keindahan pemandangan dan frekuensi penggunaan jalan tol. Makalah ini juga menunjukkan bahwa preferensi positif terhadap jalan tol pada periode ramp-up tidak selalu terkait dengan kemacetan lalu lintas seperti di wilayah perkotaan yang padat, keberadaan lalu lintas tamasya sangat potensial mempengaruhi. Kata-kata kunci: Perilaku pemilihan rute, model logit-biner, jalan tol, periode ramp-up
