By Pass Ngurah Rai is the only primary arterial road linking the traffic flow of people and goods from Ngurah Rai Airport to Nusa Dua. Peak hour traffic flow condition has exceeded the capacity of the road. To solve the above problems, it is planned to build toll roads Benoa-Bandara-Nusa Dua. The objectives of this study were to analyze the performance of existing roads with and without the toll road, the rates applicable to service users and to analyze the financial feasibility of the investment of the project. Analysis was performed for several scenarios, including the scenario-1, assuming traffic growth factor of i = 9.96% / year, the interest rate 16% / year, inflation accounted for 8.506% / year and the toll rates using rates set by the Jasa Marga. All of the cost including land acquisition and construction costs were provided by investors. It was found that for the scenario-1, the NPV is Rp 1,586,137,984,347, -, BCR: 0.4754 and IRR 3, 8676%. The results of the financial analysis indicated that investment of the toll roads Benoa-Bandara-Nusa Dua is not financially feasible. In order for this project to be financially feasible, the growth rate of vehicles should be at least i = 14.7% / year.

Abstract: Renon area is the center of the goverment system of Bali province. As one of the main street in Denpasar city, this street can represent the characteristics of Denpasar city which is the Car Free Day was held in in every Sunday morning in this street, as a simple way to reduce the air pollution and noise. The calculation in this journal is road performance, air pollution and noise level for 2 condition that is in Car Free Day and in working day. From the calculation result of road performance, the capacity of the street is 4.110 pcu/hour with degree of saturation is 0,8. The level of street service is on D category where the flow is almost unstable with high volume of traffic. The traffic volume is mostly reached the capacity and delay is frequently occur in this street. The measurement process of the level of air pollution showed that from six parameter which tested were over all are still under the standard quality which is allowed as good and medium category. The Sulfur dioksida (SO2) which was measured in busy day showed the improvement about 6,78% from the measurement which is done in Car Free Day. The nitrogen dioksida showed the improvement for about 36,35% , the carbon monoksida also showed the improvement for about 366,25%, the total dust had the greatest improvement for about 599,95% or six time greater rather than the level of total dust in Car Free Day. In the other hand, oxidantshowed the improvement for about 28,75%.The noises which occured in Car Free Day showed the average level of dB(A)is 61,65 whereas in workdays showed 72,77 dB(A). At 07.30 until 07.45 in the morning , the maximum level of noises occurs in Car Free Day and in work day.

One option to overcome traffic jam that has been implemented was by building Bali Mandara toll road. However, the connection between the toll road with the Tugu Ngurah Rai intersection has caused traffic jam and long queue. Therefore, it is required to analyse appropriate traffic management at Tugu Ngurah Rai intersection. This study aims to analyze the existing performance of Tugu Ngurah Rai roundabout and to provide the alternatives control considering both signalized roundabout and separated-grade intersection of partial-type underpass. The analysis is conducted in accordance to the Indonesian Highway Capacity Manual (MKJI, 1997). The study showed the existing performance of Tugu Ngurah Rai roundabout was at the level of service C. In addition, the degree of saturation, average delay and queue probability of the roundabout were 0.652, 10.802 sec/pcu and 6%-25%, respectively. The roundabout is predicted to reach a level of service D in 2019 with the average delay of 26.664 sec/pcu. Installing signalized traffic control at Tugu Ngurah Rai roundabaout is unable to reduce the congestion, therefore, a separated-grade intersection of underpass is such a plausible alternative. An alternative design of underpass on north-south direction in 2019 is found to be better than east-west direction. The underpass on north-south direction will have a degree of saturation, average delay and queue probability of 0,517, 9.7118 sec/pcu and 12% - 21%, respectively. These condition is equal to a level of service B. Furthermore, considering the increase of traffic flow in 2026, the underpass is predicted to experience a level of service D with average delay of 20.773 sec/pcu. Keywords: roundabout, signal, underpass, performance

Abstract : Based on data from the Central Statistics Agency (BPS) of Bali in 2013, the population density in the Metropolitan area SARBAGITA (Denpasar-Badung-Gianyar-Tabanan) was 1.057 inhabitants/km2 with an area of 1.753,63 km2 and population was 1.853.017 inhabitants. Availability of facilities and adequate transportation infrastructure is needed, but in fact the performance of roads in the city center has declined. It is characterized by an increase in travel delay problem. Traffic delay problems in the City of Denpasar commonly occur on the stretch of Gatot Subroto street. To minimize the existing problems, Denpasar City Government plans to develop an underpass at the intersection of Gatot Subroto street and Ahmad Yani street. The aim of this study was to analyze the direct benefits of underpass for road users, to analyze the costs necessary to realize and operate the underpass, and to analyze the economic feasibility of the underpass development investment. Based on primary data and secondary data were obtained from government agencies, the method of analysis in this study used the technique of Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR). Economic analysis conducted in this study used three criteria (NPV, BCR and IRR) with three interest rates (12%, 15% and 18% per year) stating that the construction of an underpass was economically feasible. For example in the second scenario where the interest rate 15% gain on the analysis of value NPV, BCR and IRR respectively is Rp. 233.462.340.102,00; 1,948 and 30,81%. Suggestions can be submitted from this research is the need to contemplate the effect of changes in land use in areas close to the area around the underpass and needed further study that takes into account the needs of additional traffic lanes.
