" ABSTRAKPergerakan arus lalu lintas menerus, memutar, memotong dan diperparah dengan adanya persimpangan berurutan dengan putaran balik, jalur kereta api yang sejajar dengan jalan mengakibatkan adanya potensi lokasi konflik. Penelitian ini bertujuan untuk menganalisa pergerakan kendaraan, jenis konflik dan kompleksitas konflik lalu lintas pada persimpangan tidak bersinyal. Metode menggunakan pendekatan konflik dan data didapat dari survei lokasi. Lokasi penelitian adalah di Jalan Raya Lenteng Agung dengan konfigurasi simpang yang kompleks dengan dua simpang berurutan. Berdasarkan analisis terdapat dua tipe konflik utama yaitu konflik memotong 36% dan menyatu 35% pada lajur dua. Terdapat hubungan antara frekuensi konflik dengan volume kendaraan yang tunjukan oleh nilai R square sebesar 0,7386 dan 0,6223. Nilai kompleksitas konflik menunjukkan pada rentang 90-120 yang dapat dimasukan ke dalam kategori perlu peningkatan (need improvement). Guna mengurangi konflik perlu dilakukan manajemen lalu lintas antara lain dengan pembuatan lajur khusus putar balik.

ABSTRACT

The movement of traffic flow constantly, rotate, crop, and aggravated by the consecutive intersection and u-turn, railway which parallel to the road and the result there causing potential of conflict?s location. This study aims to analyze the movement of vehicles, types of conflict and traffic conflict complexity at the unsignalized intersection. This study uses the approach of conflict and the data obtained from the survey location. The location of this study is at Lenteng Agung Road with the complexity of intersection configuration and two parallel intersection. There are two major types of conflict is the conflict?s merging 36% and crossing 35% blends in lane two. There is relation between conflict frequency and traffic volume of vehicles which showed by the value of R square of 0.7386 and 0.6223. Conflict complexity?s value indicate that the range of 90-120 categorized as the category of need improvement. The traffic management is needed in order to decrease the conflict through the construction of turn around special lane."

"Penelitian ini mengevaluasi keamanan lalu lintas dari area penggabungan di jalan bebas hambatan berdasarkan teknik konflik lalu lintas dalam kondisi lalu lintas yang sedang berjalan, sebagai tindakan keselamatan lalu lintas non-kecelakaan. Objek penelitian ini, menggabungkan area di Jalan Tol Kota Sidoarjo. Menggunakan Drone untuk mengambil video untuk teknik pemrosesan data. Waktu untuk tabrakan (TTC) ditentukan dengan mengevaluasi konflik lalu lintas menggunakan aplikasi pelacak. Kemudian, ambang batas keparahan TTC ditentukan. Ambang konflik serius dan perubahan jalur umum terletak antara 0–2,9 detik dan 2,9-5,8 detik, masing-masing; ambang konflik serius dan umum ujung-belakang terletak antara 0-0,73 detik dan 0,73-3,33 detik, masing-masing. panjang rata-rata jalur percepatan, persen kendaraan berat yang melintas dijalur ramp, persen kendaraan berat di lajur 1 jalur utama, kecepatan rata-rata kendaraan yang melintas dilajur 1 jalur utama yang dibutuhkan untuk berpindah lajur yang secara positif mempengaruhi indeks resiko kecelakaan perjam (HCRI), Pengukuran TTC dalam makalah ini dapat menawarkan cakupan komprehensif dengan skala yang disempurnakan, menambah pemahaman pemodelan konflik lalu lintas di area penggabungan.

This research evaluate the traffic safety of the merging area on freeway based on traffic conflict techniques in the running traffic conditions, as a non-accident traffic safety measure. The object of this research, merging areas on Sidoarjo City Freeway. Using Drone to take video for data  processing techniques. The time for a collision (TTC) is determined by evaluating the traffic conflict using the tracker application. Then, the severity threshold of TTC is determined. The threshold of serious and general lane-change conflicts lies between 0–2.9 s and 2.9- 5.8 s,respectively; the threshold of serious and general rear-end conflicts lies between 0–0.73 s and 0.73–3.33 s, respectively. average length of acceleration lane, percent of heavy vehicles crossing the ramp, percent of heavy vehicles in lane 1 main lane, average speed of vehicles crossing lane 1 main lane needed to move lanes which positively affects the hourly accident risk index (HCRI ),The TTC measurement in this paper can offer comprehensive coverage with refined scales, adding to the understanding of traffic conflict modeling in merging areas."

"The exclusive Stopping Space for Motorcycles is defined as facilities for motorcycle to stop for waiting at signalized intersection as long as red traffic light period . The RHK's has been tested in an arterial road to support the movement of the motorcycle at the signalized intersection. This paper aims to study the influence of the RHKs to reduce traffic conflict, particularly the type and intensity of conflict and also the severity of conflict between motorcycles with another motor vehicle. To test the affectivity of RHKs to reduce conflict, the traffic conflict observations were made with video cameras during the the morning and afternoon peak hours, before and after installing the analyses were carried out in the laboratory. A total of 62 cycles and 41 cycles in the morning and afternoon peak hour with total of 12214 motorcycles and 8873 motorcycles (before and after RHKs installed) were analyzed. The throughput of the intersection increased both in the morning and afternoon peak hours by respectively 11.92% and 12.31%. The conflict patterns changed significantly, but the conflict rate decreased from 133,39 conflict/1000 pcu's to 24,68 conflict/1000 pcu's on the morning peak hour and from 111,10 conflict/1000 pcu's to 24,10 conflict/1000 pcu's on the afternoon peak hour. The conflict severity also decreased from 1.83 to 1.43 on the morning peak hour and 1.96 to 1.38 on the afternoon peak hour."

"ABSTRAKPenelitian ini bertujuan untuk mengetahui sejauh mana keberhasilan implementasi penanganan keselamatan lalu lintas pada persimpangan jalan Permata Hijau-Patal Senayan, Jakarta Selatan dengan menganalisis data-data kecelakaan, data-data konflik dan kecepatan lalu lintas pada pra implementasi penanganan dan pasca implementasi penanganan. Selain itu menilai keefektifan penanganan dalam penggunaan Traffic Conflict Technique (TCT) yang didasarkan atas prinsip ?before-after analysis?. Data ?before? dikumpulkan sebelum implementasi perangkat keselamatan dan sebelum pembangunan flyover dari arah Senayan dan Permata Hijau maupun sebaliknya, dan data konflik ?after? dikumpulkan setelah dilakukan implementasi dengan menggunakan aplikasi simulasi Vissim. Hasil penelitian menunjukan bahwa adanya flyover terjadi penurunan konflik secara signifikan di beberapa titik potensi konflik, seperti pada titik T16 terjadi penurunan signifikan sebesar 94.69%.

ABSTRACT

This study aims to asses the implementation of traffic safety improvement scheme at Permata Hijau-Patal Senayan Jakarta Selatan Junction by analyzing the data of accidents, conflict and speeds in pre-implementation handling and post-implementation handling. In addition, this study also aims to measure the effectiveness in Traffic Conflict Technique (TCT) handling, which is based on the principle of before-after analysis. ?Before? data is collected before safety equipment implementation and development of ?Senayan-Permata Hijau? flyover, while ?after? conflict data is collected after implementation of Vissim simulation application. The result of study shows significant conflicts reduction in potential conflict spots caused by the existence of flyover, e.g.: in spot T16 the conflict is decreased to 94.69%."

"Urban road improvement programs, such as geometric intersection improvement or recalculation of cycle time for traffic lights, should include road safety and accessibility considerations. These components could be evaluated in a short time without waiting for accident data from police departments or accident events by using a tool known as a traffic conflict study. With a traffic conflict analysis, the effectiveness of any road improvement could be evaluated, and any traffic event involving two or more vehicles, or single vehicles taking evasive action to avoid crashes, could be investigated. Traffic conf lict studies have been used in many countries, but less extensively for analyzing road improvement projects. This paper describes traffic conflict studies which have been applied at intersections in Bandung, resulting in a new Special Stopping Space (SSS) for motorcycles at a major intersection, intersection design improvements, and traffic management improvements at intersections. This research shows the applicability of the traffic conflict study technique to road facility improvement projects in Indonesia."
