Abstract

Yogyakarta is listed among the cities with the worst congestion in Indonesia. Besides, the development of Yogyakarta has now expanded to the surrounding area and agglomerated into the Yogyakarta Urban Area (KPY). Private vehicle ownership is closely correlated to the characteristics of households. This study aims to analyze the correlation of the level of private vehicle ownership with the characteristics of households and the correlation of private vehicle ownership towards the responses of households with transportation policies that will be implemented in the future. This study fully used secondary data. The total respondents were 8,810 households, and the research location was the Yogyakarta Urban Area (KPY). The path analysis was employed to find out the causal relation between variables and the contribution between variables in the analysis. The variables used were gender, age, education level of the heads of households, total household income, the number of adult family members (> 17 years old), the number of children (<17 years old), the number of working family members, total motorcycle licenses in a household, total driver's licenses in a household, total motorcycle ownership in a household, total car ownership in a household, and the responses of households to the transportation policies that will be applied. The results of the study show that motorcycle ownership in a household is influenced by gender, age, the level of education of the heads of households, total household income, the number of adult family members, the number of children, the number of working family members, and total motorcycle licenses in a household. Meanwhile, car ownership in a household is influenced by age, total household income, the number of working family members, and total driver's licenses in a household. There is also a correlation between motorcycle and car ownership. Increasing car ownership in a household has a positive correlation with motorcycle ownership. Furthermore, motorcycle ownership has a good significance value and a positive correlation with pedestrianization policies prioritizing public transportation in the Mangkubumi-Malioboro-Kraton area.

Abstract

The rapid rise in motorcycle usage in Indonesia has contributed significantly to urban transport emissions, underscoring the need for cleaner alternatives such as electric motorcycles (EM). This study investigates the roles of extrinsic motivation (e.g., policy incentives) and intrinsic motivation (e.g., residential location, daily activity patterns, and psychological readiness) in shaping EM adoption in Yogyakarta, Indonesia. A stated preference survey was conducted with 400 conventional motorcycle owners, collecting socio-demographic data, four-day activity diaries, perceived accessibility measures, and responses to a transtheoretical model questionnaire. Using a mixed logit modelling framework, three models were estimated, progressively incorporating vehicle attributes, policy incentives, spatiotemporal factors, travel satisfaction, and behavioural readiness stages. Results show that spatial context, particularly residing farther from the city centre, public transport, and parks, has a stronger effect on EM adoption than readiness stage, with workaholic activity patterns also positively associated. Among policy measures, free battery replacement emerged as more influential than free annual vehicle tax, although range, maintenance cost, and charging time remained more critical determinants. Behavioural readiness moderates these effects: individuals in the preparation stage are significantly more likely to adopt EMs, while those in contemplation are less inclined. The findings suggest that beyond financial incentives, campaigns emphasizing EM reliability and environmental benefits, targeted toward suburban residents and high-usage riders, could accelerate adoption. These insights support spatially and behaviourally segmented strategies for promoting low-emission transport in motorcycle-dependent, rapidly motorizing cities, and inform the potential integration of market-based mechanisms such as personal carbon trading or tradable driving credits.

Abstract

AbstrakUrbanisasi yang pesat di Kota Palu telah menimbulkan tantangan terhadap mobilitas pegawai pemerintah, yang masih bergantung pada kendaraan pribadi. Penelitian ini bertujuan merancang strategi pengembangan sistem transportasi khusus berbasis efisiensi dan aksesibilitas. Pendekatan deskriptif kuantitatif digunakan dengan metode survei terhadap 250 pegawai dari berbagai instansi, untuk mengidentifikasi pola perjalanan, preferensi moda, dan faktor penentu pemilihan transportasi. Hasil menunjukkan 83% responden bersedia menggunakan angkutan khusus dengan preferensi biaya perjalanan Rp4.000–Rp8.000, waktu tunggu 5–15 menit, dan jarak halte maksimal 300 meter. Dengan menggunakan analisis GIS, dirancang rute angkutan khusus dari 18 wilayah asal perjalanan utama menuju Balai Kota dengan waktu tempuh maksimal 20 menit. Studi ini merekomendasikan pengembangan sistem transportasi pegawai berbasis kebutuhan pengguna, dengan fokus pada keterjangkauan biaya, kecepatan layanan, dan kemudahan akses, guna mendukung efisiensi perjalanan dan keberlanjutan mobilitas di Kota Palu.Kata Kunci: Aksesibilitas, Angkutan khusus, Efisiensi mobilitas, Perencanaan rute, Transportasi pegawai
