Nanyang Technological University Library ACKNOWLEDGEMENTS Alhamdulillah - Praise be to Allah SWT, the Cherisher and Sustainers of the worlds. First at all, I am thankful and grateful to my supervisor, Associate Professor Piotr Olszewski, for his guidance, advice, and encouragement throughout the duration of my research. The patience, effort and time that he devoted to me have enabled me to complete and present my research in this form. I also appreciate his generous kindness given to me on the matters not related to my research. My sincere appreciation is given to Professor Henry Fan, Associate Professor Wong Yiik Diew, Associate Professor Lum Kit Meng, and all faculty members of the Transportation Division of the School of Civil and Environmental Engineering (CEE) NTU. My individual appreciation is given to Associate Professor Harianto Rahardjo for his support and kindness to me passing through the difficulties time. I would like to thank to Mr. Choi Siew Pheng, Mrs. Ng-Ho Choo Hiang, Mr. Liew Kai Liang, Mrs. Tan-Mai Ju An, and all research students in Transportation Division, for their assistance, friendship and environment of work. Special thank is given to my best friends, Basuki E Priyanto, Satrio Wicaksono, Bayu Jayawardhana, Romyaldy, Joko Nugroho, Aine Kusumawati, Eka Firmansyah, and Ibnu Bramono, who have supported and help me along the time living in NTU and Singapore. Finally, my best appreciation is given to my wife, Windya Wardhani (Inda), for her support and understanding during the time that I felt down. Her strength and empathy has motivated me on completion of my research. To her and two my lovely kids, Naufal Muhammad Zulfikar (Fiky) and Sabrina Farah Salsabila (Sasa), I dedicate this work. 11 ATTENTION: The Singapore Copyright Act applies to the use of this document.
