Abstract

A large number of bends in Cianjur Regency makes the Cianjur Regency area prone to traffic accidents, especially for heavily loaded vehicles, one of the corners that often occurs in cases of accidents on heavily loaded vehicles is the Tapal Kuda Cianjur bend. The problem with bend Tapal Kuda Cianjur is that the bend has a small radius so it makes the curve very sharp in uphill road conditions so it is very difficult for heavily loaded vehicles to pass corners and resulting in accidents on heavily loaded vehicles. The method used is a geometric analysis method to provide an overview of field conditions and stop visibility distance analysis which aims to determine the stopping visibility on the corner so that it is expected to meet the standards set by Bina Marga so that the view of the road users when passing a corner is not blocked. The results of the geometric analysis show that the bend is still feasible to accommodate traffic loads, the bend has a spiral-spiral shape with a value of Rc=30 m, Ts= 40,599 m, Es=9,152 m with a stop visibility value at the existing condition =17,300 m and does not comply with the provisions in the minimum stop visibility distance table. So it is necessary to improve the shape of the bend using a planned speed of 60 km / h, improvement of the shape of the bend is planned using the form of SCS and FC with values of Rc= 120 m and Rc=500 m and total arc SCS=196,878 m, FC=611,982 m with the value of the repair bend stop visibility distance repair bend both spiral-circle-spiral and full circle shapes of 82,117 m and in accordance with the provisions set by Bina Marga.

Abstract

Angkutan perkotaan adalah denyut mobilitas transportasi perkotaan di dunia maju bahkan juga di negara berkembang lainnya, peran angkutan umum perkotaan sangat diperhitungkan. Di Korea Selatan, Jepang, Colombia, Brazil, bahkan di Hong Kong peran angkutan umum sampai 86%. Subsidi adalah keniscayaan agar peran angkutan umum bisa tetap eksis. Di Amerika Serikat, Inggris, Jerman, Perancis bahkan Mesir dan Turki pun subsidi kepada angkutan umum tetap dijamin negara. Di Amerika Serikat dan Eropa besaran subsidi bahkan mencapai 70% dari total biaya operasinya.Di Indonesia, subsidi dijamin dalam regulasi transportasi Nasional dalam Undang-undang Nomor. 22 tahun 2009 tentang Lalu Lintas dan Angkutan Jalan, Keputusan Menteri Perhubungan KM Hub No. 60/2007 tentang Pemberian Subsidi Angkutan Umum berbasis Jalan, dan dalam Rencana Pembangunan Jangka Menengah Nasional (RPJMN) tahun 2014-2019. Subsidi diperlukan untuk mendorong peran angkutan umum di perkotaan, namun keterbatasan anggaran pemerintah mendorong untuk dikembangkan konsep pembelian layanan melalui metode baru yaitu buy the services. Buy the services mendukung keseimbangan angkutan umum modern berbasis integrasi antara prasarana, sarana serta pengoperasian. Analisis konsep buy the services dilakukan pada dua kota metropolitan, Medan dan Denpasar untuk membandingkan kinerja pelayanan dan operasional. Studi membuktikan bahwa dengan perencanaan yang baik, buy the services bisa mengurangi subsidi pemerintah dan meningkatkan pelayanan angkutan umum.

Abstract

The growth and concentration of motor vehicles in developing cities has led to increased demand for urban mobility. Renewed commitments of Asian cities are required in order to achieve the SDG target on urban mobility as well as to enhance overall sustainability of urban transport systems and services. Cities and countries need to track the progress in improving urban mobility. With a view to support evidence based decision, the paper introduces the Sustainable Urban Transport Index (SUTI) of urban transport services, to help summarize, track and compare the state of urban mobility in Asian cities, as model for developing cities in the world. It also presents the results of pilot application of SUTI in four Asian cities: Greater Jakarta; Kathmandu; Hanoi; and Colombo. The four pilot cities were able to collect data, analyzed and assess the state of urban mobility in their city using SUTI. The assessment result supported policy makers to identify policy gaps, prioritize additional measures and investment strategies required to improve urban transport systems and services in each city. The visual output display in spider diagram was useful to comprehend state of all 10 key indicators in a glace. The pilot study demonstrated the usefulness of SUTI tool and the pilot cities were already using the results of SUTI analysis. In Kathmandu additional efforts are required to improve pedestrian infrastructure and facilities, Colombo needed to improve quality and reliability of public transport system, while Hanoi and Greater Jakarta need to put additional efforts to increase mode share of public transport system.

Abstract

Motorcycles produce a variety of sounds. Sound is synonymous with noise. Noise is big enough to have an impact on the comfort of a place that is directly related to the highway. The distance between the hospital building and the road must be taken into account. This distance is important for the realization of patient comfort in the hospital/treatment room. The volume of motorcycles, light vehicles and heavy vehicles must be controlled, especially those passing through schools/places of worship/hospitals. Traffic flow/volume of motorcycles, light vehicles and heavy vehicles have a significant effect on noise. The calculation results obtained the largest equation on the fourth day of research at the third point (sound level meter2), with a contribution of 34.22% at y = 59.11 + 0.3x1 - 0.1x2 - 0.17x3. This equation means that if there is no decrease in the volume of motorcycles, light vehicles and heavy vehicles, the noise level in SLM2 is 59.11dBA. If there is an increase in the volume of motorcycles, light vehicles and heavy vehicles, the noise significantly affects. The results of the second equation from the calculation of the first day at the third point (sound level meter3) with a contribution of 19.30% based on the equation, y = 60.54 + 0.01x1 – 0.01x2 + 0.08x3. This means that if there is an increase in the volume of the motorcycle, the noise on the SLM3 is 60.54dBA. From the results obtained, there has been a decrease in the volume of motorcycles, light vehicles and heavy vehicles that pass through RS Hermina Bogor during the Covid-19 pandemic, because many hospital visitors/users do not travel or self-isolate at home. Decrease in the number of motorized vehicles that pass in front of the hospital. RS Hermina Bogor reached 45%.

Abstract

Buses as a means of public transportation can greatly reduce traffic problems in urban areas through the use of, among other things, innovative techniques and technologies. The development of innovative technologies increasingly oriented towards the electrification of vehicle propulsion systems is expected to lead to the reduction of harmful emissions, increased vehicle efficiency, improved performance, reduced fuel consumption, and reduced noise. This study aims to determine the comparison of Transjakarta electric buses with conventional buses owned by Transjakarta, identify and evaluate the condition of the electric bus side. This study uses quantitative methods. The results of the study show a comparison of the operational cost calculation as indicated by the calculation of direct costs and indirect costs. The unit price for a bus/km for a diesel bus is Rp. 51,796, on the electric bus Rp. 224,991, and BBG buses for Rp. 82,227. where in the comparison of BOK diesel buses are cheaper than electric buses and CNG. The most expensive cost is the replacement of spare parts, especially the price of the battery which needs to be replaced every 10 years. 3,876, while bbg buses require much cheaper, which is Rp. 630. The calculation results of the electric bus battery consumption on the use of 1 route with a distance of 30.8 on weekdays on average 11.5% while on weekends it is 9.5%. At the kWh consumption, the electric bus requires the consumption of kWh per trip with a distance of 31.4 km is 23.57 kWh. From this value, it is known that the efficiency is 1.3 km/1 kWh. In charging the battery, the average battery charging time on the electric bus is 134 minutes or about 2.23 hours.
