Abstract

Pertumbuhan lalu lintas di jalan tol Perak-Waru meningkat setiap tahun dengan cukup besar, sehingga sering terjadi antrian yang panjang pada gerbang tol Untuk mengatasi penggunaan kendaraan pribadi dan meminimalisir dampak kemacetan karena tidak sesuai kapasitas jalan, salah satu solusi adalah tarif tol. Obyek yang diteliti yaitu pengendara roda empat/truck/mobil box dan trailer yang melewati ruas jalan Perak-Waru sampai menuju Kota Malang, dengan menggunakan metode pendekat Willingness To Pay untuk penentuan jumlah responde, dilakukan secara acak atau random sebanyak 240 responden dengan menggunakan tingkat kepercayaan sebesar 5%. Metode yang digunakan dalam penelitian ini perhitungan Willingnes To Pay. Hasil penelitian analisis WTP di dapatkan masing-masing pada tol Perak-Waru melalui tiga skema tarif pada penelitian ini yaitu, tarif normal, tarif (+) 25% dari tarif normal dan tarif (+) 50% dari tarif normal. Tol Perak-Waru dihasilkan WTP rata-rata sebesar Rp. 7.400 kemudian tol, kemudian pada tol Waru-Sidoarjo dihasilkan WTP rata-rata sebesar Rp. 8.000, tol Sidoarjo-Kejapanan dihasilkan WTP rata-rata sebesar Rp. 6.800 dan terakhir tol Kejapanan-Singosari dihasilkan Rp. 55.000. Penelitian ini menggunakan teknik Revealed Preference dan Stated Preference, dengan metode regresi logistik biner. Berdasarkan uraian diatas penelitian ini diharapkan dapat menunjukkan tanggapan responden dalam penentuan tarif jika terjadi kenaikan tarif tol, yang menjadikan pertimbangan bagi responden akan beralih atau tidaknya menggunakan jalur umum (non tol) atau tetap akan menggunakan jalur tol.

Abstract

Surabaya and Jakarta are two major cities in Indonesia that serve as national centers of business, economic activity, and government administration, resulting in high intercity mobility between them. The operation of the Trans‑Java Toll Road has accelerated the growth of sleeper bus services, while executive rail remains a preferred mode due to its stable comfort and reliability. This study aims to identify passenger characteristics, analyze the probability of mode choice based on factors such as fare affordability, travel time, comfort, calmness, and safety, and propose service improvements for both modes. A revealed preference survey was conducted with two hundred respondents who had already selected either executive rail or sleeper bus for their Surabaya–Jakarta trip. The data were analyzed using binary logistic regression to model the probability of choosing each mode. The results show that most passengers belong to the choice‑user category at 65.5 percent and are predominantly private‑sector employees at 52.5 percent. The key determinant for selecting executive rail is the importance placed on calmness and comfort, yielding a predicted probability of 78.52 percent. In contrast, the dominant factor influencing sleeper bus selection is safety consideration, with a predicted probability of 96.52 percent. These findings indicate that executive rail attracts passengers seeking a quiet and comfortable travel environment, while sleeper buses appeal to travelers prioritizing safety and time efficiency supported by toll‑road connectivity. The study concludes that service improvements should focus on enhancing comfort and safety to strengthen the attractiveness of both premium land transport modes along the Surabaya–Jakarta corridor.

Abstract

Transportation maintains a vital role in enabling trade and mobility, which significantly contributes to regional economic growth. Therefore, this study used Partial Least Square Structural Equation Modeling was chosen because it can analyze the causal relationship between latent variables simultaneously, while PLS-SEM was preferred because it focuses on prediction, is tolerant of normality assumptions, and is suitable for complex models with survey data. A purposive sampling technique was used and 250 data were collected through on-site survey. All manifest variables proved both valid and reliable. The variable of passenger satisfaction was shown to be low, with an R² value of 0.046, indicating that the ability of the construct or model to explain the satisfaction is very weak and almost negligible. In contrast, the loyalty variable, achieved a high R² of 0.911 which is included in the very strong category. This result shows that the model can explain 91.1% of the variance in loyalty, indicating that the model’s variables are excellent at predicting loyalty and have a high explanatory power. These results provide actionable insights for terminal administration and transport policy, highlighting the necessity to enhance service characteristics that directly improve traveler satisfaction to maintain passenger allegiance.

Abstract

Interconnected public transportation plays an essential role in facilitating community mobility, especially in ensuring seamless mode transfers at integrated locations. This study aims to evaluate passengers’ expectations and satisfaction toward the integration of mode transfer services in the Suroboyo Bus public transportation system. The research was conducted at five main integration stops, namely Joyoboyo Intermodal Terminal (TIJ), Purabaya Terminal, Dukuh Menanggal Bus Stop, Marmoyo Bus Stop, and UINSA Bus Stop. The analytical methods employed in this study are the Customer Satisfaction Index (CSI) and the Importance Performance Analysis (IPA). Primary data were obtained from 250 respondents through questionnaire distribution, with the sample size determined using the Slovin formula. The results show that the CSI score of 78,16% indicating that the passengers' satisfaction level falls within the satisfied category. However, the IPA results indicate a gap between expectations and satisfaction across all indicators, with eight attributes emerging as priority areas for improvement. Therefore, it can be concluded that the integration of mode transfer services in the Suroboyo Bus system has generally met passengers’ expectations, although further improvements remain necessary to ensure a more optimal and inclusive travel experience for all users.

Abstract

Passenger satisfaction is an important indicator of service performance in public transportation, particularly for local railway services that support regional mobility. This study aims to evaluate passenger satisfaction with the local train operating on the Madiun–Solo route using the Customer Satisfaction Index (CSI) method. The research was conducted in the operational area of DAOP 7 Madiun and involved 250 passengers as respondents. Data were collected through field surveys using structured questionnaires that assessed six service dimensions: tangibles, reliability, responsiveness, assurance, empathy, and accessibility. The CSI analysis results indicate an overall satisfaction index of 69.50%, which falls within the “satisfied” category, suggesting that the service generally meets passenger expectations. Nevertheless, several service attributes, including service frequency, seating arrangement, ticketing convenience, and feeder transport availability, show relatively lower satisfaction levels and require improvement. These findings emphasize the importance of continuous service enhancement to improve passenger experience and increase the attractiveness of local rail services. The results are expected to serve as a reference for transportation operators and policymakers in developing sustainable railway services along the Madiun–Solo corridor.

Abstract

U-turn planning is regulated by several Indonesian regulations, such as the Regulation on Separator Planning Procedures No. 014/T/BNTK/1990, the Specification for Lane Separator Openings, SKSNIS-04-1990 F, and the U-Turn Planning Module (U-Turn Planning Guidelines), No. 06/BM/2005. According to these regulations, u-turns cannot be too wide or too narrow, and the number of u-turns on a single road section is also regulated, as is their position. Therefore, in this context, u-turns are not always a solution for traffic efficiency. They can be a nuisance if not properly planned. The analysis was conducted in several stages. First, a visual calculation was performed to determine the average delay caused by the u-turn. Second, an appropriate traffic model was found to obtain traffic parameters and predict future traffic events. The traffic model was determined using linear regression and selected using the chi-square test. Third, calculate the traffic parameters if the delays identified in the first stage are removed, then compare the parameters from the first stage (where delays are present) with the parameters from the third stage (where delays are absent). The initial hypothesis in this study is that delays will positively impact traffic performance. This is based on the results of previous research mentioned above. Keywords: u-turn, traffic performance, delay, traffic model, regression
