The capacity of a road section depends on many factors, such as the width of the carriageway, the permissible visibility, the slopes, the turning radii, the composition of the cars, the maneuverability and the design of the cars. The development of the automotive industry leads to improved performance of cars and improved throughput. Changing all of these components changes the bandwidth. When the capacity is calculating the composition of the traffic flow became one of the key factors. Mobile traffic is characterized by the composition of different (by age and purpose) vehicles. The composition of the traffic flow is displayed as a percentage. Obtaining and analyzing the algorithm for determining the capacity of traffic flow on a particular section of road (interchange). The analyze of the current state of car use in Ukraine and select the optimal algorithm for obtaining real flow data on the road section was made. The main task of the engineer during the design of a certain section of the road is to ensure the maximum capacity of the road section. Maximum throughput is achieved by improving the road surface, widening the roadway (increasing the number of lanes and installing appropriate signs), allocating reversing lanes and installing reversing traffic lights. When calculating the capacity, it is necessary to take into account when characterizing the relationship between cars in the flow in different road conditions. Intervals between cars in a stream can change even at high intensity of movement that in turn quit

There was a build-up of lumps of sand on the road, precisely Tambelang-Durjan. This build-up of sand chunks occurs because many of the piled sand hauling trucks that pass on the road is obstructed because the road section has been damaged (potholes) and is unfit for passage, resulting in obstruction of traffic flow. In addition, the width of the section is not in accordance with the technical requirements of the 2011 Government Regulation. Therefore, it requires a flexible pavement re-planning and a Cost Budget Plan for land transportation lines, so that motorist access is comfortable. Planning flexible pavement using Laston with a planning age of 10 years obtained flexible pavement thickness, namely 4 cm thick AC-WC, 6 cm thick AC-BC, and 40 cm of Upper Foundation Layers (LPA) with the estimated size of the Budget Plan The cost of the flexible pavement construction of Tambelang- Durjan of Sampang Regency with a length of 1,145 km in the amount of Rp 5,744,585,463.00Terjadi penumbukan bongkahan pasir urug tepatnya di ruas jalan Tambelangan-Durjan. Penumpukan bongkahan pasir ini terjadi karena banyak truk pengangkut bongkahan pasir urug tersebut yang melintas pada jalan itu terhambat karena ruas jalan mengalami kerusakan (berlubang) dan tidak layak dilalui, sehingga  yang mengakibatkan terhambatnya arus lalu lintas. Selain itu lebar ruas tidak sesuai dengan persyaratan teknis Peraturan Pemerintah tahun 2011. Oleh karena itu, memerlukan perencanaan ulang perkerasan lentur dan Rencana Anggaran Biaya untuk jalur transportasi darat supaya akses pengendara nyaman. Perencanaan perkerasan lentur menggunakan Laston dengan umur rencana 10 tahun didapatkan tebal perkerasan lentur yaitu AC-WC setebal 4 cm, AC-BC setebal 6 cm dan Lapis Pondasi Atas (LPA) setebal 40 cm dengan besar perkiraan Rencana Anggaran Biaya pembangunan perkerasan lentur ruas Tambelangan-Durjan Kabupaten Sampang sepanjang 1,145 km sebesar Rp 5.744.585.463,00.

ABSTRAKPersimpangan Jalan Sangkuriang–Jalan Kolonel Masturi, Kota Cimahi sering mengalami kemacetan karena tingginya volume lalu lintas. Lampu lalu lintas yang tersedia pun tidak digunakan karena dinilai kurang efektif, sehingga perlu dilakukan penelitian untuk memecahkan permasalahan tersebut. Penelitian ini dilakukan dengan menggunakan metode survei langsung di ruas jalan pada tiap lengan simpang dan juga persimpangannya pada waktu puncak yaitu pukul 06.00–08.00 WIB dan 16.00–18.00 WIB. Kinerja simpang dianalisis menggunakan Manual Kapasitas Jalan Indonesia Tahun 1997. Pada kondisi eksisting, yaitu simpang tak bersinyal, diperoleh nilai derajat kejenuhan ( ) sebesar 1,299 dan 1,323 pada periode pagi dan sore hari, dimana nilai tersebut tidak memenuhi syarat, karena memiliki nilai lebih dari 0,85. Pada kasus simpang bersinyal, harus dilakukan penyesuaian geometri, dimana pada kasus ini, dilakukan percobaan penambahan lebar efektif pada tiap lengan menjadi sebesar 4 m, dan dihasilkan rata-rata nilai derajat kejenuhan ( ) sebesar 0,76 dan memenuhi syarat, dimana nilai kurang dari 0,85. Kata kunci: simpang tak bersinyal, simpang bersinyal, derajat kejenuhan. ABSTRACTSangkuriang St.–Kolonel Masturi St. Intersection, Cimahi City often faces the traffic jam because of the high traffic volume. The existing traffic lights are not used because they are considered to be less effective, so the research needs to be done to solve these problems. This research was conducted with using a survey method directly on the road section on each approach and also its intersection at the peak times, specifically at 06.00–08.00 WIB and 16.00–18.00 WIB. The intersection performance was analyzed using the 1997 Indonesian Road Capacity Manual.

Abstract The Meulaboh - Tapak Tuan road is the main access road linking several districts, Aceh Barat, Aceh Barat Daya, Aceh Selatan, and Aceh Tengah. After the earthquake and tsunami hit Aceh, its economies experienced rapid growth. This greatly influences the distribution of traffic volume on specific road segments, including the increasingly congested Meulaboh - Tapak Tuan roads. As a result, the number of private vehicles is increasing. The purpose of this research is to evaluate the performance of roads in the area based on the Indonesian Road Capacity Manual, as well as to analyze the level of road services at present and in the future. The analysis of the road performance can be measure by several indicators such as traffic flow (Q), capacity (C), degree of saturation (DS), free flow velocity (FV), and level of service on the road section. The calculations were obtained from 3 days direct observation in the field from 07:00 to 19:00 with Monday and Thursday representing workdays and Saturday representing weekend. The highest conversion value of traffic flow in 2020 was 1357 pcu/hour for (Q), 2654 pcu/hour for the actual capacity value (C), and 0.51 for the degree of saturation (DS). The analysis results show that the degree of saturation < 0.75. According to Marga (1997), it is considered in good condition with smooth traffic flow at the service level of C. The road performance analysis for the next five years for traffic flow was 2093 pcu/hour for Q and 0.79 for the degree of saturation (DS). The service level is categorized as level D. It is necessary to find solutions and alternatives to reduce the degree of saturation (DS) value by increasing the value of capacity.

The Relationship

Often we encounter several obstacles that cause traffic concentration at several points on a road segment which causes traffic movement to slow down and even stop. Concentration of traffic flow occurs at intersection points, such as one at the Pilau-Keruing intersection, where traffic moving on the Pilau road is forced to slow down when the traffic flow from Keruing road turns right to cut the flow. Therefore, it is very important to know the effect of turning movement on the smooth flow of traffic. Data collection was carried out by sending several surveyors to the field to obtain secondary and primary data. Furthermore, the analysis of road performance using the 1997 Indonesian Road Capacity Manual. The average space speed obtained from the graph of the relationship between DS and vlv is vlv=28 km/hour. The average speed from the results of the speed survey on the road section gives a value of vlv = 29.6 km / h with conditions without any obstacles to the flow of turning from the Keruing road to the Pilau road, and vlv = 25.6 km / h with the presence of turning current obstacles . There was a decrease in average travel time of 5.9 seconds, with a decrease in traffic speed of 4 km/hour due to the influence of vehicles turning from Keruing road to Jati road.

Traffic lights play such important role in traffic management to control the traffic on the road. Situation at traffic light area is getting worse especially in the event of emergency cases. During traffic congestion, it is difficult for emergency vehicle to cross the road which involves many junctions. This situation leads to unsafe conditions which may cause accident. An Automatic Traffic Light Controller for Emergency Vehicle is designed and developed to help emergency vehicle crossing the road at traffic light junction during emergency situation. This project used Peripheral Interface Controller (PIC) to program a priority-based traffic light controller for emergency vehicle. During emergency cases, emergency vehicle like ambulance can trigger the traffic light signal to change from red to green in order to make clearance for its path automatically. Using Radio Frequency (RF) the traffic light operation will turn back to normal when the ambulance finishes crossing the road. Result showed the design is capable to response within the range of 55 meters. This project was successfully designed, implemented and tested.

Computerized traffic modeling makes it possible to find out the modification needs to assess the traffic flow on the roads and detect likely problem areas in order to take timely measures to eliminate them. Competent preparation of a road network formation plan based on the acquired information makes it possible to reduce the load on the road transport line, avoid traffic jams, and also reduce the average time spent by drivers on the roads. The macroscopic and microscopic models of the cars flow were analyzed by authors to implement the computer model. The article considered the model of the cellular automata by Nagel–Schreckenberg, with the author’s addition that takes into account the presence of the road sections inaccessible for driving in. The need to modify the lane change algorithm was implemented: the condition of the need to change the lane when car is meeting an inaccessible road section was added. And also the “polite” drivers algorithm for bypassing inaccessible areas with a high density of the traffic flows was proposed. Such a model is realized on Python programming language. An analysis of vehicles behavior with different traffic density and location of inaccessible road sections for two- and three-lane roads was carried out based on that model modification.

The control of roads traffic, of noise, of all other problems which occur on national road sections are much more manageable through Geographic Information Systems. The possibility of changing parameters in real time from a database, allows rapid information on problems encountered and efficient solutions at a more sustained rate.This paper presents a proposed solution to improve the Geographic Information System by adding noise data, by carrying out a case study on the road section Sag - Voiteg that connects Timisoara (Romania) and Belgrade (Serbia). The existing GIS system was established in 2012 according to the legislation in force at the time. As Year 2017 will mark the next stage of issuing the noise maps according to the rules set by CNOSSOS-EU, the measurements done for this study will follow these new methods. CNOSSOS-EU accurately describes the objectives and methodology requirements, establishes clear criteria for road traffic and sound propagation.The advantage of uniformity standards and methods of control in all EU Member States allows comparative studies on pollution, the number of people affected, etc.
