Abstract

As the number of transport increases, the congestion and accidents on the highway increase. Accidents or traffic jams can be caused by an intersection, especially at unsignalized intersections. In Indonesia, accidents and vehicles continue to increase, especially at intersections. Apart from growing accidents, density is also increasing due to increasing or increasing human activity. Research at unsignalized intersections is carried out to prevent increased density and ensure traffic conditions run smoothly. The location of the study to be carried out is at an unsignalized intersection in the Majalengka district. The method used in this research is quantitative, and the data collection technique used is by entering primary and secondary data. Four-way intersection This round has four approaches, each with two paths. The results obtained from calculating traffic volume by conducting direct surveys in the field for three days are divided into two: total flow volume and flow volume of main roads and minor roads. The essential capacity (C0) obtained at a four-way intersection Babakan is 2/2 UD, 2900. Meanwhile, the level of service at the intersection depends on the degree of saturation obtained from the traffic flow value divided by the load capacity. In the previous chapter, the value of the degree of saturation in the north, east, west, and south directions is very high, causing the level of service to be poor. The research results can be used to conclude that the level of service at the four-way intersection Babakan will be more optimal if the load capacity can be increased so that the degree of saturation is low and does not cause high traffic jams.

Abstract

Road geometry design is a method of planning roads geometrically or involving the computation a angles through a process. For roads geometric design, it is necessary to assess the suitability of design criteria with applicable guidelines, namely the Road Geometric Design Guidelines. Therefore, this study will conduct a geometric design assessment of application of the existing road geometric design of the Jatigede East Ring Roads, and adjust it to the "Road Geometric Design Guidelines". The research method used in this research is the evaluation research method of the research object, namely the Jatigede East Ring Road Section is the road to the Jatigede Dam tourist area which is not by the road geometry standards. It has a sharp bend less than Rmin = 110, which the 1997 highway requirement for collection roads with Vr = 60 km/h. Such road conditions can cause insecurity and discomfort for road users. Therefore, the authors conducted research with the title "Case Study of Road Geometry Evaluation Towards Tourism Area Case Study: East Ring - Jatigede Dam, Sumedang - Indonesia" Geometry improvements are because many angles are not suitable. To obtain geometry data in the field using Google Earth and Global Mapper, the measured data is coordinate data and elevation data, then using Microsoft Excel to process the measurement results and input them into the Autocad program. Based on the results drawn, geometric analysis. Conducted from 32 corners obtained from the research, only 17 corners with a radius of 115 m meet the criteria. The other 31 turns have radii smaller than the minimum radius, which is quite dangerous for a speed of 60 km/hour. There are steep descents and climbs in some locations, with 28% of the road having a slope much greater than the maximum requirement of 8%.

Abstract

Concerns about the density of roads and acceleration have been brought up globally by the increase in motorized vehicles, especially in urban areas where infrastructure development is still in progress. The issues of road density and congestion are the main focus of this study, with a particular concentration on road speeds on Pangeran Muhammad's road, which leads to Cirebon Street in Rajagaluh, about 100 meters away. This study's principal goal is to ascertain the average speed and vehicle density on the road by applying qualitative research techniques and on-the-ground observations. We looked at the volume of traffic, the passing velocity, and the density of the road. to gather primary data. The quantity of automobile traversing was ascertained using Traffic Counter software and Microsoft Excel 2021.; MKJI 1997 provided secondary data. In street data analysis involving two-way double-track (2/2 UD), cut line road markings designate the column separator, and each column has a width of ± 3.5 meters. The traffic and congestion on the road under review are reflected in the density data. Monitoring and evaluating these parameters is required to obtain data regarding traffic density and road performance in the area under study. The data indicates that most vehicles crossed the reviewed street between 4 and 5 p.m., when the highest vehicle volume occurred, with a peak of 2505.6 vehicles per hour (Smp/Hour). Additionally, observations show that on Sunday, between 11 a.m. and 12 p.m., when traffic is smoother, vehicles reach their average peak speed of 50.51 km/h, allowing for relatively high speeds.

Abstract

The signalized intersection at the Cigasong roundabout in Majalengka City is where the Majalengka-Cikijing road, Majalengka-Rajagaluh road, Sindangkasih troops road and Majalengka-Jatiwangi road meet. The traffic problem that often occurs at the Cigasong roundabout is traffic jams, especially at every rush hour the traffic flow increases more densely than at other times. In various regions in Indonesia, traffic lights can also have a negative impact on traffic activities that occur. in urban areas. The aim of this research is to find out how the signalized intersection at the Cigasong roundabout performs, so that traffic problems caused by the many factors above can be resolved. By conducting research on the signalized intersection located at the Cigasong roundabout in Majalengka City, we can gather a number of information about the signalized intersection that coincides with this roundabout, which means that if there is a roundabout there should not be a signalized intersection. Basically, the function of a roundabout is to slow down the speed of vehicles, in contrast to signalized intersections where the average vehicle speed is very fast when the light is green. The Cigasong roundabout is classified as a fairly large roundabout because this roundabout is also a roundabout which connects several road routes to various areas in Majalengka to several sub-districts such as Cigasong, Jatiwangi, Maja and Rajagaluh, as well as directions to other cities such as Cirebon, Indramayu, Kuningan. With this, there will be a suggestion that will be the answer to the problem of signalized intersections located at the Cigasong Roundabout, Majalengka City, so that it can be resolved through research, the results of which are in accordance with what is happening at the roundabout and so that this suggestion can be realized at the Cigasong Roundabout, Majalengka City.

Abstract

In today's globalized world, much software is developed to make work easier to implement. This software is demonstrated using AutoCAD Civil 3D® to demonstrate how geometric road design can be completed briefly. In this case, the purpose of geometric planning is to evaluate the effectiveness of manual geometric planning using AutoCAD Civil 3D®. This journal's geometric road planning implements qualitative methods. The geometric planning of the road that became the subject of this journal's research is located on Jalan Kertawangunan - Kadugede, with a road plan length of 9.3 km as an additional alternative to Kuningan Regency's new outer ring road. The calculation of horizontal alignment required the minimum bend (Rmin) and transition arch (Ls) values. Therefore, it is necessary to plan the assembly ahead of time before planning the corridor. The corridor's function is to determine the location of cut and fill based on road planning. As a result, planning a path with AutoCAD Civil 3D® is more effective and efficient, and it can retrieve the necessary data quickly. There are four points of interest with different types of curves in road traffic planning. The plan speed (Vr) was set to 60 km/h, the maximum superelevation slope (e-maks) was set to 0.08, and the transverse friction coefficient (f) was set to 0.153. The average excavation volume obtained from this planning is approximately 1,900,000 m3
