Abstract

One of the phenomena of transportation problem currentl.y is the congestion which cxrurs at highwaybottlenecks. Congestion is detennined btJ the low capacity at the bottleneck point compared to theentrance rood segment before the bottleneck. This capacity reduction can be inft~d by the decrease inthe number of traffic lanes, the reduced width of rood shoulders and traffic signs.Location of the study is on a signaHzed intersection (MT Haryano Street) and unsignalized intersection(Cilincing Street). Traffic congestion Analysis is caused bi; the bottleneck based on the principle dinamictraffic with deterministic queuing method (DQA).There are three point of conclusion based on the analysis is determined queuing length, the queuing rate,Physical. diagram discharging. Firstly, queuing length are in the signalized intersection is 5.98 km andunsignalized intersection is 38.01 km. Secandl.y, queuing rate of rehicles produced by the method DQAat signalized intersection of 10,075 pcu smaller than the maximum cumulative volume at the intersection(19,900 pcu). Finally, Pln;siml diagram discharging rate is means when congestion cxrurs untilqueue missing (during t2). The Physical. diagram discharging rate at signalized intersection is 19.01km;hour and unsignalized intersection is only 4.15 km/ hour. From those amclusions show the queueinglength will increase the queuing rate and reduce congestion at the existing speed.

Abstract

Sultan Hasanuddin Airport is one of the transport nodes that have an important role in ensuringeffective implementation of inter-mode transport and efficient. To realize that goal PT Damri providesairport buses as a service alih nwde to improve accessibilihj to and from the airport. However, theavailabilihJ of the airport is not opti"mal due to limited available fleet and a route served has not beenable to reach the entire cihJ of Makassar and surroundings. In this research, an analysis of theoptimization efforts airport bus at Sultan Hasanuddin Airport.T7ie metlwd used is descriptive quantitative metlwd with a review of the operations and sclieduling.T7ie analysis was divided into 3 phases, namely analysis of the performance of the e:risting airport buswith reference to the standard indicators of the Department of Transportation public transportationservice, the identification of tlie origin and destination wnes potential using maximum entropi; methodand analysis of the needs of the fleet.Based on tlie analysis of the data obtained that tlie level of bus service Hassanuddin Sultan InternationalAirport as one of the integrator nwdes are still at the level of being. According to the analysis results canidentify potential zone is a zone 2 witli tlie needs of a fleet of 4 and 14-minute headwm;, zone 7 witli tlieneeds of a fleet of 72 units and headwm; 4 minutes, zone 8 units with 45 units and fleet needs 6 minuteslieadwm;. Based on tliese zones, tlie airport bus service as a nwde of transportation than can re VJJ.timizedbiJ increasing the service area bi; 40%, 107% load factor and the communities served bi; 85%.

Abstract

T1re advantages of toll road as the highwm; tend 111£lke tire driver tend to ignor the safehJ endangeredhimself and others. T1rerefore, it needs many efforts to minimize the possibility of an aaident. T1re tollroad accident frequently happened on tire Jaka.rta-Okampek toll road. The number and level of accidentson this toll road quite high. 'Dre approach used in this research is descriptive analysis of thepercentage bi; using priman; survei; and secondan; data collected from accident reports PT.JasaMarga which is tire depiction of the location of aaident research at Jaka.rta-Cikampek toll road.From tire research, tire causes of accidents at aaident prone areas in tire Jakarta-Cikampek toll road isdue to the driver's condition factor (79.7%), damage to vehicles (19.4%) and road conditions (0.14%).Descriptively driver who had an aaident on tire toll roads is largely caused bi; lack of anticipation(60.8%). The most frequent accident occun'ence time between of 12:00 to 18:00 P.M. T1re truck is avehicle h;pe that is often involved in aaiden.ts. Front of the rear end collision is tire most common h;peof aaident. Accidents more frequently in sunny ·weather conditions.At the Jakarta-Cikampek toll road there are some segments which include the accident spot km 12 -km 14 for Jakarta route toward Cikampek and km 10 - km 14, km 25 - km 27 and km 29 - km 30 fortire reverse direction. Dominating factor in the location of tire critical points including the driver's lackof anticipation, tire driver's drowsiness and the tires burst.

Abstract

Rasio kematian akibat kecelakaan lalu lintas di Indonesia menempati posisi pertama di dunia. Jumlah korban tewas mencapai 25.266 orang dari 103.645 kasus kecelakaan pada tahun 2021. Sementara itu, kesalahan manusia sering ditunjuk sebagai kontributor utama dalam investigasi kecelakaan, yaitu sebesar 61%. Kasus kecelakaan yang melibatkan bus jarak jauh menjadi perhatian besar karena berpotensi menelan banyak korban dalam satu kali kecelakaan. Oleh karena itu, langkah konkret untuk menyelesaikan hal ini menjadi urgen. Salah satu cara yang bisa dilakukan adalah dengan mengidentifikasi tindakan tidak aman secara sistematis. Artikel ini menggunakan prinsip-prinsip Human Factors Analysis and Classification System (HFACS) untuk mengidentifikasi dan mengklasifikasikan faktor manusia dan organisasi yang terlibat dalam kecelakaan bus jarak jauh. Penelitian ini menggunakan pendekatan kualitatif dengan melakukan observasi lapangan, wawancara mendalam, dan studi pustaka data investigasi kecelakaan KNKT tahun 2020-2021. Analisis data penelitian mengunakan piranti lunak Nvivo. Hasil penelitian menemukan bahwa beberapa tidakan tidak aman dilakukan oleh bebagai pihak. Tindakan tidak aman yang dilakukan oleh pengemudi meliputi menunda perjalanan, gagal menyalip kendaraan, berulang kali menggunakan rem, tidak menggunakan engine brake dan exhaust brake, melakukan kebiasaan tidak aman, dan tidak memakai sabuk pengaman. Selain itu, prasyarat tindakan tidak aman yang rumuskan oleh manajemen sumber daya personel adalah kurangnya pemahaman tentang rute jalan, keterbatasan informasi cuaca, dan tidak memahami kondisi jalan. Adapun tingkat pengawasan yang tidak aman meliputi tindakan yang menugaskan pengemudi yang tidak terdaftar, tidak ada pelacak GPS, dan pengemudi bus yang tidak patuh. Adapun di tingkat atas, tindakan tidak aman organisasi meliputi kurangnya sosialisasi fasilitas tanggap darurat, pelatihan pengemudi yang minim, kurangnya penilaian pemadam kebakaran, tidak ada penilaian risiko, tidak dilakukan identifikasi potensi bahaya, SOP diterapkan, dan tidak ada manajemen risiko dan Sistem Manajemen Keselamatan (SMK). Dengan memahami penyebab kecelakaan lalu lintas, maka perbaikan perlu dilakukan di setiap tingkatan.
