Abstract

Public transportation plays a crucial role in supporting community mobility while also reducing traffic congestion, pollution, and travel costs. The Trans Jatim Corridor IV bus service on the Bunder–Paciran route is an initiative by the East Java Provincial Government to enhance the quality of public transportation services. This study aims to assess user satisfaction with Trans Jatim’s services and analyze the probability of mode shift from previous modes of transportation to Trans Jatim. The methods employed include the Customer Satisfaction Index (CSI), Importance Performance Analysis (IPA), and probability analysis using a Stated Preference approach and binary logistic regression. A total of 98 respondents were involved in data collection. The analysis results show a CSI index value of 0.85, indicating a "very satisfied" category. The IPA identified two priority attributes for improvement: safety and comfort inside the bus (X3_2) and the availability of proper bus stops (X3_3). Meanwhile, binary logistic regression results indicate that gender and frequency of use significantly influence mode shift decisions. The probability of mode shift is recorded at 89.2% for female respondents and 89.6% for respondents who travel daily. This study concludes that while the overall quality of Trans Jatim services is very good, improvements are still needed in several service aspects.
