Modelling the modal choice of transport is an important step in urban transport planning. In this study, modelling the transport modal choice of Bandar Barn Bangi residence going to work in Kuala Lumpur was conducted. The trip makers have three choices of transport mode, that is call commuter train and bus. Motocycles and taxis are ignored due to their in extensive usage for this kind of trip. It was found that monthly income, travel cost (including parking charges) and travel times are the main factors that influence the transport choice. The relationships of these variables to the transport choice were formulated in the form of trip end model and trip interchange models. In the trip end model, two stages decision structure with logistic function was adopted. Monthly income was found to give a good probability ode. In the trip interchange model, a single stage decision structure with multinomial logic function was adopted. The developed model was found out to closely replicate the actual transport mode choice when independent variables such as monthly income, travel cost by cal travel time for both modes of transport and the ratio of fare charges / monthly income of commuter train and bus were included in the model.
Pemodelan pemilihan kenderaan adalah satu juzuk penting dalam perancangan pengangkutan bandar. Dalam kajian ini, pemodelan pemilihan kenderaan penduduk Bandar Baru Bangi ketika hendak pergi bekerja ke Kuala Lumpur telah dilakukan. Bagi perjalanan ini terdapat tiga pilihan, iaitu menaiki kereta, keretapi Komuter dan bas. Motosikal dan teksi telah diabaikan kerana penggunaannya sangat sedikit. Didapati pendapatan bulanan, kos perjalanan termasuk kos tempat letak kereta dan masa perjalanan sangat mempengaruhi pemilihan ragam pengangkutan. Hubungan antara pemilihan kenderaan dengan pemboleh ubah-pemboleh ubah ini telah dirumuskan dalam bentuk model zon penghujung dan model antara zon. Dalam model zon penghujung, struktur pilihan dua peringkat beserta fungsi logistik telah digunakan. Analisis ini telah menunjukkan pendapatan bulanan telah dapat memberikan kebarangkalian pemilihan kenderaan dengan baik. Dalam model antara zon pula, struktur pilihan satu peringkat dengan fungsi logik multinomial telah digunakan. Model yang dibina didapati menganggarkan pemilihan kenderaan menghampiri keadaan sebenar apabila pemboleb ubah-pemboleh ubah pendapatan bulanan, kos perjalanan berkereta, masa perjalanan ketiga-tiga ragam pengangkutan dan nisbah tambang / pendapatan bagi bas dan keretapi Komuter digunakan.
