Perisian simulasi lalu lintas mikroskopik mempunyai beberapa kegunaan seperti penilaian prestasi, penambahbaikan pelan, operasi kawalan lalu lintas, reka bentuk dan pengurusan kemudahan pengangkutan. Kajian ini membentangkan penggunaan perisian simulasi lalu lintas terkenal, VISSIM dalam operasi lalu lintas bagi plaza tol di Malaysia. Kajian ini menilai keseluruhan operasi tol terhadap dua jenis plaza tol yang bersistem tertutup di lebuhraya Malaysia bagi mendapatkan pembolehubah yang mempengaruhi operasi tol. Pembolehubah ini memberi kesan terhadap keupayaan plaza tol yang sebenar dari segi purata dan panjang beratur yang maksimum. VISSIM telah digunakan untuk membina model plaza tol laluan utama dan plaza tol laluan susur iaitu masing-masing plaza tol Juru dan plaza tol Jawi, untuk mengkaji operasi tol serta kapasiti yang sebenar. Bagi tujuan simulasi operasi di tol plaza data mikroskopik untuk setiap kenderaan yang tiba dan berlepas dari plaza tol telah di perolehi melalui rakaman video. Rakaman video telah diambil daripada dua sumber. Sumber pertama adalah daripada kamera CCTV yang telah dipasang manakala sumber kedua adalah daripada kamera-kamera CCTV pihak PLUS yang terdapat di lorong tol. Data yang dikumpul di plaza tol Juru dan Jawi adalah berbeza dari segi bilangan lorong, konfigurasi lorong, bayaran tol, lokasi lebuh raya, permintaan lalu lintas, serta ciri-ciri komposisi lalu lintas. Model-model plaza tol ini kemudiannya telah ditentukur mengikut keberkesanan ukuran dan parameter penting supaya sepadan dengan operasi di plaza tol yang sebenar. Keputusan menunjukkan bahawa masa perkhidmatan adalah parameter yang paling penting untuk menilai operasi di plaza-plaza tol. Selain itu, masa perkhidmatan untuk memasuki plaza tol adalah jauh lebih rendah berbanding masa perkhidmatan untuk keluar tol. Dapatan kajian menunjukkan bahawa peratusan aliran lalu lintas bagi kenderaan berat mempunyai kesan yang besar terhadap panjang beratur di plaza tol Juru dan Jawi. Selain daripada itu, model-model tersebut juga telah digunakan untuk meramalkan operasi plaza tol-plaza tol pada masa hadapan iaitu setelah kutipan tol secara elektronik (ETC) dilaksanakan sepenuhnya. Dapatan-dapatan ini menunjukkan bahawa pelaksanaan ETC penuh pada bahagian masuk di kedua-dua plaza tol Juru dan plaza tol Jawi tidak menambah baik operasi plaza tol. Walau bagaimanapun, pelaksanaan ETC penuh di pintu keluar telah menambah baik operasi tol dengan lebih ketara. Telapi, pelaksanaan ETC penuh di pintu keluar Plaza Tol Jawi telah mempengaruhi secara negatif panjang barisan di lorong-lorong Touch 'n Go dan Smart TAG disebabkan oleh kedudukan persimpangan lampu isyarat yang berhampiran dengang plaza tol Jawi. Kajian ini telah membenkan dua sumbangan kepada operasi trafik di plaza tol. Sumbangan pertama ialah berkaitan ramalan operasi trafik di plaza tol pada masa akan datang selepas pelaksanaan sistem kutipan tol elektronik sepenuhnya di plaza tol konvensional. Sumbangan kedua ialah berkaitan anggaran kapasiti sebenar di plaza tol konvensional. __________________________________________________________________________________ Microscopic traffic simulation software has several applications, such as performance evaluation, plan improvements, traffic operation control, design, and transportation facility management. This study presents the application of the well-known traffic simulation software VISSIM in the operation of toll plazas in Malaysia. This study evaluates the overall toll operation of two types of closed system toll plazas in the Malaysian expressway to gain insight into the variables that influence toll operations, which in turn affect the actual capacity of toll plazas in terms of average and maximum queue length. VISSIM was used to build toll plaza models for the mainline and ramp toll plazas which are Juru and Jawi respectively, to study their toll operations and actual capacities. In order to simulate the toll operations at toll plazas, microscopic data were obtained for each vehicle arriving and departing the toll plazas through video recordings. Video recordings were taken from two sources. The first source was from the installed CCTV and the second source was from the PLUS CCTV cameras at the tollbooths. The collected field data of the Juru and Jawi toll plazas differed in terms of number of lanes, lane configuration, toll base fee, expressway location, traffic demand, and traffic composition characteristics. The toll plaza models were then calibrated according to the measure of effectiveness and key parameter to match real world toll operations at toll plazas. Results revealed that service time is the most important parameter for evaluating the toll operation of toll plazas. Moreover, service time for entry is much lower than the service time for exit. The findings indicated that the percentage of heavy vehicles in traffic flow has a significant impact on the queue lengths at the Juru and Jawi toll plazas. Apart from that, the models were used to predict the operation of toll plazas in the future upon implementation of full electronic toll collection (ETC). The results indicated that the implementation of full ETC at the entry of both the Juru and Jawi toll plazas did not improve the operations of the toll plazas. However, the implementation of full ETC at the exit significantly improved the toll operations. But, the implementation of full ETC at the exit of the Jawi toll plaza has negatively influenced the queue lengths of Touch 'n Go and Smart TAG lanes due to the location of the signalised intersection which is near to Jawi toll plaza. The study has managed to contribute to two major findings at the traffic operations at toll plaza. The first contribution is on the prediction of traffic operation at the toll plaza in the future after the implementation of full electronic toll collection system at conventional toll plazas. The second contribution is on the estimation of the actual capacity of the conventional toll plazas.
