Abstract

Road safety is in the interest of every driver and the community around the road. Drivers often exceed speed limits and violate traffic signs. This issue has always been at the core of the world's roads. Zona Selamat Sekolah (ZoSS) didesain agar kendaraan yang melewati daerah ZoSS berada dalam kecepatan rendah (maksimal 30 km/jam). Speed seriously impacts the safety of drivers and other road users. In the province of West Java, many still ignore speed on certain roads, which is one of the causes of accidents. One often ignored is the Panyingkiran-Majalengka road, a major road with several schools. The type of research used is quantitative research with descriptive methods, which describe the speed facts at the research location. The data needed in this study are primary data, where primary data is data that is directly obtained in the field (km/h) at the research location. Several measurements can measure speed including Time Mean Speed, Running Speed, Journey Speed, and Spot Speed. The speed of vehicles on Monday-Wednesday is between 28 and 36 km/h, with an average speed of 32 km/h. Meanwhile, the speed of each vehicle ranged from 27-40 km/h with an average speed of 34 km/h. From the field survey results, the ZoSS markings and speed limit signs are not visible. The cause of the high speed in the Safe School Zone is the lack of supporting facilities such as road markings and signs.

Abstract

A one-way traffic control system is a traffic system that converts a two-way road into a one-way road. This system aims to increase safety, road, and intersection capacity. This can improve the smoothness of traffic, which is usually applied in urban areas. Majalengka also implements a one-way road traffic system in several areas, such as the Majalengka Square area. This research aims to determine the system for regulating one-way road traffic so that drivers have the awareness to obey traffic rules without violating one-way road traffic. The case study in this research is located on Jalan One, Alun-Alun Majalengka Area, Jl. Ahmad Yani, Majalengka Kulon, Kab. Majalengka, Majalengka Regency, West Java. The data used in this research is primary data obtained directly through observation, personal interviews, or experimental results. The traffic volume on Jalan Ahmad Yani Majalengka Kulon is measured by counting the number of vehicles passing at the observation point. The survey was carried out directly at the research location for two days, namely Tuesday and Sunday, with a period of 1 hour divided by 15 minutes. Each period is held in the morning from 06.30-07.30, in the afternoon from 12.00-13.00, and in the afternoon (16.00-17.00). The survey results are in the form of a manual grouping of each type of vehicle. Therefore, data collection and calculations are required to determine the volume and side resistance on a road. After data collection and calculations have been carried out, it can be concluded that the volume of traffic flow in the Majalengka Square area is quite dense in the morning, and the side obstacle class in the afternoon is medium class.

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

The road is a facility that is very important for the community to achieve a desired goal, for that we need a road that is safe and comfortable for its use. Road damage often occurs every year, especially on roads that are often traversed by vehicles with a lot of volume (congested ) and vehicles that are heavily loaded (overloaded) such as on the Sukahaji – Maja road, which causes the speed of users to slow down (drop) and have an impact on reducing population mobility and the economy of the surrounding community. The purpose of this research is to determine the level of road damage using the Payment Condition Index (PCI) method. The survey method or PCI refers to ASTM D6433 (Standard Practice for Roads and Parking Lots Pavement Condition Surveys). Pavement Condition Index (PCI) is a road pavement condition assessment system based on the type, level, and extent of damage that occurs and can be used as a reference in maintenance efforts. This PCI value has a range of 0 to 100 with the criteria of excellent, very good, good, fair, poor, very poor, and failed. Based on the analysis using the PCI method, for the type of damage that occurs on the Sukahaji-Maja road for the flexible pavement/asphalt type, 6 types of damage occur, namely alligator cracking, striping, grain release, collapse, vanished, and potholes. In Table 4.2 the average PCI value obtained is then entered into the parameters as in the table so that the road can be categorized as damaged, namely Poor (Damaged). So this road needs to be included in a road improvement program on an ongoing basis.

Abstract

Highways are one of the land transportation accesses that support human movement in driving and sending goods from one region to another. The geometric of the road is the highway building above the ground level both vertically and horizontally with the assumption that the ground surface is not flat. Horizontal alignment is often referred to as road situation or road alignment. Corners are where the horizontal alignment is most important. A transverse slope at a bend called superelevation counteracts the centrifugal force the automobile experiences as it makes the turn. The quantitative method can also be interpreted as a research method that looks at reality, symptoms, and phenomena that can be classified, are comparatively constant, tangible, measurable, and observable, and there is a causal link between the symptoms. This study's road evaluation used a 60 km/h design speed and 3.5 m of road width. Using the contour data obtained, road evaluation was carried out using AutCAD® Civil 3D. Based on the calculation results above, the Majalengka-Cikijing road is a hill road type. Then, for the horizontal alignment with a speed of 60 km/hour, the results obtained from 11 horizontal alignments all belong to the Spiral-Cirle-Spiral alignment type.

Abstract

The process of building a transportation infrastructure presents a unique challenge in the field of civil engineering. Bridges play an important role in supporting human mobility and transportation, as well as in delivering goods and services to various locations. A bridge structure must not suffer excessive deflection to have good service capabilities. This research seeks to find the amount of deflection of composite girder under live load and dead load. By inserting the load that occurs, this study wants to identify the deflection that happens using SAP2000 software. SAP200 is a sophisticated software application widely used in the field of structural engineering for the analysis and design of various types of structures. SAP2000 enables engineers to evaluate the behaviour of structures under different loading conditions, including static and dynamic loads, ensuring that designs meet required safety and performance standards. The findings show that based on the RSNI T-03-2005 Standard, the maximum deflection tolerance is L/240, where L is known as the total bridge span, which is 17.5 cm, while after being analysed by SAP2000, it is known that the total deflection that occurred on the composite girder is 17,2 cm. The findings underscore the importance of using advanced simulation tools like SAP2000 to predict structural behaviour accurately. This research highlights the necessity of precise deflection analysis in civil engineering projects to ensure that transportation infrastructure can withstand the loads they will encounter during their service life. This research is designed to serve as a reference for challenges discovered for future research.
