The highway is one of the infrastructure for the smooth traffic. One part of the road that are considered necessary to be analyzed and evaluated is an intersection. Three Gadut intersection is non signalized intersection. The traffic flow is quite dense, and lack of discipline of road user factors competing space to pass the crossing, resulting in congestion is very influential on traffic conditions at peak hours in the morning, afternoon and evening. Prior to conducting the survey, the first to do is survey the condition of the intersection that includes geometric characteristics and traffic volume. From the analysis of environmental data, side friction factor to the junction of three Gadut is the criteria being. Rated capacity (C) the smallest is 3706.3 smp/hour, the degree of saturation of 1.1 smp/hour. This value is over the limit permitted values manually indonesian road capacity of 0.8 to 0.9 (1.1> 0.9), it is concluded that the traffic flow is the crossroads of three Gadut saturated traffic flow. The queue probability value between 128.8% - 157.4% with a total delay largest average 11.57 seconds/smp. It is concluded that the chances of a queue at the intersection of three Gadut very large, so it could cause congestion.

ABSTRACT: 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.

ABSTRAKPersimpangan merupakan suatu bagian jalan yang menjadi pusat pertemuan dari berbagai pergerakan arus lalu lintas. Pada tipe simpang tak bersinyal, sering dijumpai titik-titik konflik arus lalu lintas yang mengakibatkan kemacetan arus lalu lintas terutama pada saat jam-jam sibuk. Contoh kasus terdapat di Kota Bandung, terjadi pada persimpangan Jalan A.H. Nasution dan Jalan Cikadut. Lokasi ini dipilih karena selain kemacetan yang disebabkan oleh titik-titik konflik arus lalu lintas yang tidak teratur pada saat jam sibuk, di sekitar jalan pada simpang ini juga merupakan kawasan pertokoan, pemukiman, sekolah dan juga terdapat pom bensin. Berdasarkan permasalahan tersebut, dilakukan perhitungan dan analisis data pada kondisi awal simpang, didapat nilai derajat jenuh (DS) sebesar 0,983 untuk pagi hari dan 0,937 untuk sore hari. Karena hasil perhitungan simpang pada kondisi awal tidak memenuhi syarat MKJI 1997, yaitu DS < 0,85, maka perlu dilakukan perhitungan ulang dengan beberapa alternatif agar nilai DS bisa memenuhi.Kata kunci: persimpangan, kemacetan, derajat jenuh, MKJI 1997. ABSTRACTIntersection is a part of the road that becomes the center concourse of various traffic flow movements. In the type of unsignalized intersection, there are often traffic flow conflict points which cause traffic jams, especially during rush hour. Examples of cases are in the City of Bandung, occurred at the intersection of A.H. Nasution Street and Cikadut Street. This location was chosen because in addition to congestion caused by irregular traffic flow conflict points during rush hour, around the road at the intersection this is also a shopping area, residential, school and gas station. Based on these problems, data calculations and analysis are carried out in the initial intersection condition, obtained saturated degree (DS) values of 0,983 in the morning and 0,937 in the afternoon. Because the results of the intersection calculation in the initial conditions did not comply the requirements of the Indonesian Highway Capacity Manual of 1997 (IHCM 1997), that’s DS < 0,85, it is necessary to recalculate with some alternative that value of DS can comply.Keywords: intersection, congestion, degree of saturation, IHCM 1997.

Overcrowding often occurs in DKI Jakarta, especially on Jalan Gatot Subroto. This location is one of the biggest business centers in Jakarta. Roadside activities that impede traffic flow are called side friction. Side friction is an impact on traffic performance resulting from road segment activities. Highway capacity is also influential. That happens because the available highway capacity is no longer able to accommodate the increasing traffic flow. Therefore, research was conducted. To calculate the highway capacity, observations were made to see the number of vehicles. It takes the perception of side frictions using questionnaire data. Questionnaire data collected  100 respondents. So, the results show that section is in the VL (Very Low) side obstacle class, which occurs in the morning while the L (Low) side obstacle class occurs in the afternoon and evening. The results estimation of the side drag factor data shows that the volume is greater than the highway capacity. The correlation between observation data and questionnaire results vehicles parked or stopped on the side of the road and vehicles from roadside access have a sequential weight order, while pedestrians and non-motorized vehicles have non-sequential weights. Further research to expand the questionnaire and get more precise results. ABSTRAKKepadatan sering terjadi di DKI Jakarta khususnya di Jalan Gatot Subroto. Lokasi ini salah satu pusat bisnis terbesar di Jakarta. Aktivitas sisi jalan dapat menghambat arus lalu lintas disebut hambatan samping. Hambatan samping merupakan dampak terhadap kinerja lalu lintas yang dihasilkan dari aktivitas segmen jalan. Selain itu, kapasitas jalan juga berpengaruh. Hal ini terjadi karena kapasitas jalan yang tersedia sudah tidak mampu untuk menampung arus lalu lintas yang semakin tertambah kepadatannya. Oleh karena itu dilakukan penelitian. Untuk menghitung kapasitas jalan, dilakukan observasi untuk melihat jumlah kendaraan. Selain itu, dibutuhkan persepsi hambatan samping menggunakan data kuesioner. Data kuesioner terkumpul sebanyak 100 responden. Maka, hasil menunjukan ruas Jalan Gatot Subroto berada di kelas hambatan samping VL (Very Low) terjadi di waktu pagi hari sedangkan kelas hambatan samping L (Low) terjadi di waktu siang dan sore hari. Hasil dari estimasi faktor hambatan samping data menunjukan volume lebih besar daripada kapasitas jalan. Korelasi anatra data observasi dengan hasil kuesioner menunjukan bahwa kendaraan parkir atau berhenti di sisi jalan dan kendaraan dari akses sisi jalan memiliki urutan bobot yang berurutan sedangkan untuk pejalan kaki dan kendaraan tidak bermotor memiliki bobot yang tidak berurutan. Penelitian selanjutnya, diharapkan dapat memperluas kuesioner dan mendapatkan hasil yang lebih tepat.
