"The choice among modes of intercity transport depends on conditions of not only intercity transport modes but also intracity transport in both the departure city and the arrival city. Intracity transport conditions might be advantageous for one intercity mode and disadvantageous for others. Intercity and intracity transport conditions are complex and need to be approached systemically. This study proposes an approach based on the passengers’ preferences. The logit model was adapted to evaluate the transport modes’ choices in competition. This model is called the “Adapted Mixed Multinomial Logit Model” (AMML). It was applied on the Jakarta-Bandung corridor in both directions. It contributes to a complete approach for intercity transport mode choice by considering the influence of the intracity transport conditions in both the departure and arrival cities. The results proved that the choice of intercity transport mode depends not only on its own quality of service but also, importantly, on that of the intracity transport systems."

"Penelitian ini membahas tentang permasalahan transportasi antar kota pada dua kota yang berdekatan di Indonesia, dan juga terjadinya persaingan antar moda pada koridor Jakarta-Bandung. Preferensi penumpang menjadi pertimbangan utama untuk pemilihan moda. Pada studi ini dibahas pengembangan model Logit karena model ini banyak digunakan sebagai metode untuk mengeksplorasi masalah pilihan modal yang melibatkan banyak variabel yang berbeda. Model dasar Logit tidak kompatibel untuk memecahkan masalah yang ditemukan, oleh karena itu diusulkan "Adapted Mix Multinomial Logit (AMML)" Model sebagai alat untuk analisis terhadap keputusan akhir penumpang dalam pilihan moda. Salah satu bagian dari penelitian ini berkaitan dengan identifikasi dan pemahaman tentang masalah transportasi dalam kota pada kota asal dan kota tujuan pada pilihan moda transportasi di koridor Jakarta-Bandung (Jakarta-Bandung dan arah Bandung-Jakarta). Bagian kedua dari penelitian ini berkaitan dengan proses keputusan akhir dengan menganalisis hasil kuesioner yang ditujukan kepada pengguna koridor Jakarta-Bandung. Dengan mempertimbangkan karakteristik masing-masing moda antarkota, hasil analisis akhir dapat diidentifikasi moda transportasi antarkota yang paling kompetitif untuk setiap arah dari kota asal ke kota tujuan.

The present work deals with the transportation problematic between two Indonesian cities, and also with the high modal competition on the Jakarta-Bandung corridor. Passengers preferences are the main variables for the final modal choice. In transportation, the Logit models are widely used as a method to explore the problematic of modal choices involving a lot of different variables, but in this research, they are not compatible to solve our defined problems because there are some particular identified variables to be taken into account. Therefore we propose the "Adapted Mixed Multinomial Logit (AMML)" Model as a tool for analysis towards passenger's decision in modal choices. One part on this research deals with identification and understanding of the intracity transport problems of origin and destination on the choice of transport mode in Jakarta-Bandung corridor (Jakarta-Bandung and Bandung-Jakarta direction). The second part of this research deals with the final decision process by analyzing the results of questionnaires addressed to many users of the Jakarta-Bandung corridor. Taking into account the characteristics of each intercity mode of transportation, the analysis identifies the most competitive intercity transport mode for each situation from departure city to arrival city."

"Penelitian ini menganalisis karakteristik interaksi antarkota di Indonesia melalui pendekatan pengangkutan udara untuk penumpang dan kargo pada tahun 2008-2011. Dengan menggunakan pendekatan model gravitasi, ditemukan bahwa terdapat hubungan positif antara pengangkutan udara antarkota dengan besaran Produk Domestik Regional Bruto, populasi, struktur ekonomi, interaksi antar kota utama dan dan terdapat hubungan terbalik dengan jarak sebagai proksi penghambat interaksi. Adapun pengaruh beberapa kota utama memberikan hasil yang berbeda di masing-masing estimasi. Pemisahan analisis untuk wilayah Indonesia Barat, Indonesia Timur dan antarwilayah Indonesia menemukan bahwa pengangkutan udara untuk masing-masing wilayah memiliki karakteristik tersendiri.

This study analyzes the characteristics of the domestic intercity interaction of Indonesia?s passenger and cargo air transport in 2008-2011. By using the gravity model approach, it is found that there are positive correlations between the intensity of intercity air transportation with Gross Domestic Regional Product, population, economic structure and interaction between the hubs. It is also shown that there is an inverse relationship of distance as a proxy inhibitor for interaction. The influence of several major cities provides different results in each estimation. Segregated analysis were done for interaction in western region, eastern region and between the two regions in Indonesia. The analysis provides clear evidence of unique characteristics for each region."
