In developed countries, road capacity values derived from time headway is in accordance to their local traffic characteristics. In theory, time headway standards are developed using statistics models. These standards however, are not necessarily relevant to use in Indonesia. This is because of the differences in traffic conditions and motorists behaviours between those in developed countries and Indonesia. This study is to develop the time headway distribution model and subsequently to determine lionk-road capacity in the city of Denpasar, Bali Province. The study consists of time headway data analysis, model calibration and validation and road capacity values??determination. The study found that normal distribution model fitted the local traffic conditions. Road capacity values are of  2,466 pcus/hour and 2,900 pcus/hour obtained from time headway model and the Indonesian Road Capacity Manual (MKJI) respectively.

The arterial roads in tourism areas show a lack of control over activities that occur on the arterial roadsides. This study constructs a speed-flow behavior model to analyze the influence of side friction events under mixed traffic flows on arterial road performances in Bali. This event is dominated by the entry and exit of vehicles from road access points. The study results show that in friction conditions, the speed of the motorcycle is significantly affected by the presence and speed of other motorcycles and light vehicles, but in base conditions, it is significantly affected by the presence and speed of all types of vehicles. Meanwhile, the speed of light vehicles is significantly influenced by the presence and speed of motorcycles and other light vehicles. A further study is required to analyze the influence of motorized vehicles on the selection of heavy vehicle speed on arterial roads. Due to side frictions, a decrease in road capacity (pcu/hour) was found between 14.37% and 26.60% while a decrease in speed was between 13.79% and 76.19%. These show a significant side friction problem on arterial roads in tourism areas. The road control policy, particularly on roadside access is needed for these arterial roads.

The high proportion of motorcycles and lack of lane discipline at signalized intersections under mixed traffic conditions are the motivation to conduct this study. The discharge headway models are constructed at three (3) signalized intersections in the SARBAGITA urban area in Bali. The result shows that motorcycles affect saturation flow due to their shorter headway than light vehicles while increasing discharge headway of other vehicles. The discharge headway between pairs of heavy vehicles is longer than these of motorcycles due to their slower acceleration at signalized intersections. This study also found that the discharge headway plays a significant role in determining the saturation flow and capacity of a signalized intersection. If a heavy vehicle is one of the pairs, then it has the potential to have a headway exceeding the other vehicle pairs. This indicates, however, that the higher proportion of motorcycles at the signalized intersection approach does not necessarily mean shorter discharge headway. There may be other influencing factors, such as the riding behavior of motorcyclists. The dominance of motorcycles can affect the value of the saturated flow, but an increase in the proportion of heavy vehicles may reduce the effect of motorcycles on the saturation flows.

Bali, a tourism center of Indonesia, has been rapidly developed. Unfortunately, the development is not followed simultaneously by the development of adequate transportation network, as a result, traffic congestion are inevitably occurred along every urban road in the district. Therefore integrated development and regional transport planning therefore, is urgently required. In this study, trip generation is determined using Category Analysis. It is Figured out from the household based interview that Denpasar Barat zones are found to have the largest trip generation while Pecatu zones are found to be the smallest. Most of the household trips generated use private vehicles (94.95%) and the rest uses public transport. This also indicates that public transport services in Southern Bali still need to be developed. Keywordscategory analysis, household-based, trip generation AbstrakPembangunan Bali Selatan sebagai pusat pariwisata Indonesia berjalan cepat. Namun, ini tidak diimbangi pengembangan jaringan transportasi yang memadai, sehingga sering terjadi kemacetan hampir pada semua jaringan jalan perkotaan. Kebutuhan merencanakan "Pembangunan dan Transportasi Wilayah" secara terintegrasi sudah sangat mendesak. Dalam penelitian ini, tahapan penentuan bangkitan perjalanan mengaplikasikan metode Analisis Kategori. Berdasarkan hasil wawancara berbasis rumah tangga, diketahui zona Denpasar Barat memiliki bangkitan perjalanan terbesar, sementara yang terkecil zona Pecatu. Hampir semua bangkitan perjalanan rumah tangga menggunakan kendaraan pribadi (94,95%) dan sisanya transportasi umum. Hal ini juga menunjukkkan bahwa peningkatan pelayanan Angkutan Publik masih berpeluang besar untuk dikembangkan di Bali Selatan.
