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.

Abstract Traffic congestion in the City of Surakarta gave rise to a phenomenal figure among motor vehicle drivers, called the Traffic Control Volunteers or abbreviated as Supeltas. This Supeltas is present on the road to help organize the movement of traffic, as happened at the Surakarta Ganesha Unsignalized Intersection. This study aims to determine the influence of the existence of Supeltas on capacity, degree of saturation, delay, and queuing opportunities that occur at the intersection. The analysis was carried out using the 1997 Indonesian Highway Capacity Manual. The results showed that the intersection without Supeltas had a capacity of 3,114.03 pcu/hour and a degree of saturation of 1.47, while the same intersection but with Supeltas had a capacity of 3,136.81 pcu/hour and a degree of saturation of 1.51. These results indicate that Supeltas has a positive influence on the performance of the intersection. Nevertheless, the degree of saturation in the location increased due to the increase in traffic volume as well as increased capacity. Keywords: unsignalized intersection, intersection performance, intersection capacity, degree of saturation  Abstrak Kemacetan lalu lintas di Kota Surakarta memunculkan sosok fenomenal di kalangan pengendara kendaraan bermotor, yang disebut Sukarelawan Pengatur Lalu Lintas atau disingkat Supeltas. Supeltas ini hadir di jalan untuk membantu mengatur pergerakan lalu lintas, seperti yang terjadi di Simpang Tak Bersinyal Ganesha Surakarta. Penelitian ini bertujuan untuk menentukan pengaruh keberadaan Supeltas terhadap kapasitas, derajat kejenuhan, tundaan, dan peluang antrian yang terjadi di simpang tersebut. Analisis dilakukan dengan menggu-nakan Manual Kapasitas Jalan Indonesia 1997. Hasil analisis menunjukkan bahwa simpang tanpa Supeltas memiliki kapasitas sebesar 3.114,03 smp/jam dan derajat kejenuhan 1,47, sedangkan simpang yang sama tetapi dengan Supeltas memiliki kapasitas sebesar 3.136,81 smp/jam dan derajat kejenuhan 1,51. Hasil tersebut menunjukkan bahwa Supeltas mempunyai pengaruh positif terhadap kinerja simpang. Meskipun demikian, derajat kejenuhan di lokasi tersebut meningkat karena bertambahnya volume lalu lintas di samping kapasitas yang juga meningkat. Kata-kata kunci: simpang tak bersinyal, kinerja simpang, kapasitas simpang, derajat kejenuhan

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.

On-street parking leads to reduced road capacity and decreased traffic performance of the certain road. Therefore, this study was conducted to evaluate the feasibility of on-street parking based on road performance. The study was conducted at Central Business District namely Peunayong, Banda Aceh. Based on the Indonesian Highway Capacity Manual (IHCM) one of the performance parameter values is Degree of Saturation (DS). The data needed for calculation of DS are the geometric conditions, traffic volume and the side frictions. The results indicate that on-street parking facilities on segment 2 of Khairil Anwar Street should be evaluated, as the DS value is greater than 0.75 (unstable road condition), by changing parking patterns into a parallel configuration or eliminating parking facilities. Furthermore, the parking configuration of R.A. Kartini Street also needs to be rearranged. Despite the stable road performance, this road is uncomfortable to pass because there is only one lane remained due to unfeasible parking patterns and existence of street market along the segment. The road performance of Khairil Anwar Street (segment 1), Ahmad Yani Street, W.R Supratman Street, T.P. Polem Street, Twk. Daudsyah Street and Ratu Safiatuddin Street is in stable condition, with DS < 0.75. This indicating that on-street parking facilities can be maintained. While as for the W.R. Supratman and Ahmad Yani Street should be evaluated in year of 2019 to avoid traffic jam along this corridors.

The City

Broadband highways are being built in major cities around the world to combat traffic congestion. At the same time, existing buildings are demolished or powerful overpasses are raised above them. However, it often turns out that newly created highways quickly exhaust their capacity, and traffic jams are formed on them again. This situation indicates that increasing the capacity of the highway does not solve the problem of traffic jams, but often aggravates it, since as a result of this increase, even more cars are drawn to the highway from adjacent territories, often exceeding their current capacity. At the same time, the streets in the surrounding areas are empty and their potential is not used to the full extent. This situation has arisen due to the disruption of the city road network by lengthy obstacles in the form of ravines, rivers, floodplains of small rivers, and railways. This situation can be corrected by "stitching" the streets over the gaps by building bridges and overpasses with a capacity corresponding to the capacity of the "stitched" streets. Most of the gaps fall on relatively small streets, which approach the banks of fairly wide floodplains of small rivers and streams, and this makes it advisable to build mainly small (with a span of 20-25 m) and relatively inexpensive bridges, with the number of spans sufficient to cover the floodplain and reach the levels of road surfaces of connected streets. There will be several hundred such bridges over the river barriers in a large city, for example, Moscow, and several hundred more, taking into account the required number of them over the railways, and in the end, about a thousand. It is proposed to erect bridge buildings instead of simple road bridges. Such structures combine two city functions; the first of them is transport, the second is public, residential, or economic, depending on the needs of the city and the environmental situation at the construction site. An important requirement for the second function is a quick return on the financial assets invested in the construction and income from the operation of the building acceptable to the investor. The bridge part of a bridge building should become the property of the city.

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.

The city of Denpasar is the capital of Bali Province, as well as the centre of various activities including government offices, hospitals, schools/ universities, trade and services, as well as tourism. Traffic congestion in the city of Denpasar is increasing from year to year, especially at the point of the intersection node, such as at the signalised intersection of Udayana University Sudirman Campus. The high trip attraction to Udayana University Campus has exacerbated the congestion of the intersection. The purpose of this study was to examine an alternative to managing the traffic flow using the Vissim software. The required data included the intersection geometric data, traffic volume and signal timing. The calculation of the intersection’s performance was conducted based on the Indonesian Highway Capacity Manual (IHCM). The simulation of the traffic flow management was conducted with the help of the Vissim software. The results of the performance analysis of the intersection conduced using Vissim Software indicated that the application of Vissim software was valid. The traffic management proposed has reduced both queue length and delay time.

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.
