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.

Side Friction

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.

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.

An unsignalized intersection is a part of a road where currents from different directions or directions meet. There was a conflict between currents from theopposite direction and intersecting each other, resulting in congestion along the arms of the intersection. Likewise, at the intersection of four arms without a signal at Sibuhuan Market, Padang Lawas Regency, North Sumatra, there is a congestion caused by the reduction in the effective width of the road due to parking on the road. At the intersection of four arms without a signal at Sibuhuan Market, Padang Lawas Regency, North Sumatra, there is a congestion caused by side obstacles, a high vehicle population that is not matched by the availability of adequate infrastructure so this research aims to analyze the performance of the four-arm intersection without a signal. based on Indonesian Highway Capacity Manual (MKJI 1997) and analyzes them to improve the performance of these unsignalized intersections. The analysis of the results showed that the intersection performance for the unsigned intersection conditions in the existing condition with the parking on the side of the road which reduced the effective width, the maximum total flow was 2341 pcu / hour, capacity (C) = 2707.06 pcu / hour, and the degree of saturation (DS) = 0.86, intersection delay (D) = 14.62 seconds / pcu and queuing opportunity (QP) 30.03 - 59.32%. Therefore, it is necessary to recalculate with various alternatives so that the DS value meets the requirements of the Indonesian Highway Capacity Manual, which is < 0.75.

Traffic congestion is a problem that is often faced by Indonesian big cities. It is related to land use in an area that causes on-street parking. The main cause is the imbalance between demand and supply, namely the need for parking during rush hour exceeds the capacity of existing parking. Another consequence is the increasing of side barriers resulting in the delays on certain roads. Shopping area in Jl.Kapasan, Surabaya is one of the densely areas attracted most people of Surabaya to conduct trading activities and shopping for daily needs. The denstiy of this region will affect the performance of traffic flow and causing delays.The study aims to identify on-street parking in Jl.Kapasan shopping area, consequences arising from parking on the road, and determine the level of service or performance of roads around this shopping area. The analytical methods used are derived from Indonesian Highway Capacity Manual 1997. Based on calculation and analysis, the capacity of Jl.Kapasan without parking on the road was 1468 pcu/hour and with on-street parking was only 1276 pcu/hour.
