Abstract

Economic and health aspects are most significantly affected by traffic congestion due to delays in the execution of daily tasks, causing a huge waste of time, effort, and focus, as well as other additional costs. Like the intersection at SMPN 1 Majalengka or what is usually called the Abok intersection, which is one of the access roads to the economic center, the traffic problem that often occurs at the intersection at SMPN 1 Majalengka is congestion, especially at rush hour. traffic flow is increasing. denser than at other times. The aims of this research is to analyze the traffic engineering that occurs at the signalized intersection of SMPN 1 Majalengka which can cause congestion so that in the future this research will look for solutions to be more careful in traffic engineering. The research methodology used in this research is a qualitative method. This research was conducted at the Abok signalized intersection which is located near SMPN 1 Majalengka, Majalengka Regency. Based on the table above, it can be seen that the degree of saturation in the four directions has a value of 0.88. It can be concluded that the degree of saturation in all four directions is the same, namely 0.88 and according to MKJI 1997 this figure is included in the creeping dense category. The resulting degree of saturation is quite high, causing the service level value to creep up. This result will increase the risk of traffic jams at the intersection. So attention is needed in carrying out good traffic management.

Abstract

Despite the significant impact of street lighting on road user safety, there is a lack of monitoring for compliance with national standards (SNI) for many streetlights in West Java Provin The majority of accidents in the region result from factors such as overtaking, loss of vehicle control, tire blowouts, inadequate lighting, and unexplained incidents or brake failures. The Jatibarang-Jatitujuh Road is an example where lighting is neglected despite its susceptibility to high-speed traffic. The spacing between streetlights on this route, commonly used to connect Kabupaten and Kota Indramayu, is considerable, and tree branches obstruct some. Despite being a winding road prone to accidents, the Jatibarang-Jatitujuh Road remains busy with passing vehicles, especially at night. Poor street lighting contributes to the heightened risk for road users. Respondents express dissatisfaction with the illumination on the Jatibarang-Jatitujuh road, with an average satisfaction level of 6.73. Conversely, the importance level averages 9.1, indicating a high significance level and possibly exceeding respondents' expectations. The graphical analysis highlights vital indicators in each quadrant, with high-priority aspects including Road Lighting for safe driving, Road Lighting for road crossers, Road Lighting for road crowds, Road lighting for bridges, Road Lighting to mitigate the risk of road damage, Road Lighting for pedestrians, Road Lighting for uphill and downhill roads, and Road Lighting for driver's vision.

Abstract

The discrepancy between the rise in automobile ownership and the suboptimal capacity of roads can be attributed to the escalating demands for transportation and the elevated purchasing power of individuals. This situation is particularly prevalent in high social and economic activity, such as the Kadipaten Traditional Market area, leading to frequent side obstacles. These obstacles, occurring in the market area, can be assessed based on various factors including pedestrian crossings, parked vehicles, vehicle flow in and out of the area, and slow-moving vehicles. This study aims to analyze the impact of side obstacles, traffic density, and road performance in the Kadipaten Traditional Market area. The research was conducted in three phases: the initial study, volume survey, and side obstacle assessment. This study utilizes primary and secondary data. The primary data encompasses the count of side obstacles and the traffic flow volume within the research area, which is subsequently computed and examined. The secondary data was sourced from the Central Statistics Agency for Majalengka city, encompassing population statistics, and then analyzed by the 2023 Indonesian Road Capacity Guidelines. Based on the findings, the saturation level was determined to be 0.615, indicating a moderate level of saturation as per the 2023 Indonesian Road Capacity Guidelines. This suggests that while traffic flow in the Kadipaten Traditional Market area is dense but relatively smooth, the presence of side obstacles significantly hampers road performance.

Abstract

Traffic signs are the main thing that is very important for road users; of course, they help in terms of safety and security for drivers. Unsignalized traffic signals at intersections have been identified as the most dangerous locations in traffic. Not only in other countries, Indonesia has also implemented traffic signs at intersections, especially on highways. This journal aims to analyze factors that increase the risk of traffic jams and are prone to morning, afternoon, and evening accidents at the intersection of Jalan Sukaraja Wetan-Kulon, Jatiwangi District, and Majalengka Regency. This research was located at an unsignaled intersection, precisely at the Sukaraja Wetan-Kulon intersection, Jatiwangi sub-district, Majalengka district. The method used in this journal is quantitative methods. The Sukaraja Wetan-Kulon intersection has four approaches; each approach has two lanes. The data was obtained from calculating traffic volume, which involved conducting a survey directly at the location, namely in the field for two days, and divided into two, namely total flow volume and flow volume of main roads and minor roads. The basic capacity (Co) obtained at the intersection of four Sukaraja Wetan-Kulon roads is 2/2 UD, which is 2900. At the junction of four, the level of service depends on the degree of saturation, which has been obtained from the traffic flow value divided by the load capacity. The conclusion from this research is that the data obtained in the chapter above shows that peak traffic flow occurs on Tuesdays in the afternoon period at 16.00-17.00 with a total traffic flow volume of 7818.2 pcs/hour. The capacity of the Jalan Simpang Empat Sukaraja Wetan-Kulon greatly influences the value of the degree of saturation.

Abstract

In Majalengka, there are only a few public transportation options, including Angkutan Kota (public minivans), online motorcycle taxis (Ojek Online), and even traditional becak (pedicabs) can still be found in the city. The absence of trains and the limited number of public minivans may contribute to the lack of attractiveness of public transportation in Majalengka. Even in urban areas of Majalengka, some regions cannot be reached by public minivans. This study aims to evaluate the level of public transportation service to the community, providing evidence of the quality of public transportation services in Majalengka Kota. The research methodology employed in this study is quantitative. Majalengka Kota serves as the central government area of Kabupaten Majalengka, making it the hub of activities for its residents. This is due to the presence of various facilities that make Majalengka Kota a centre for activities, including recreational centres, food centres, favourite schools, etc. In conclusion, the Customer Satisfaction Index (CSI) in this study is 68%, which falls into the satisfactory category. The comparison of the importance and performance levels of transportation services shows a minimal GAP of 0.094, which is still positive, indicating a satisfactory and secure level of service. Lastly, the Importance Performance Analysis (IPA) graph identifies two variables, Administration (A) and Going (G), as the main priorities for improvement. The government should address these areas to anticipate and enhance future transportation services.

Abstract

At night, road lighting is very important for a driver. Apart from reducing the number of traffic accidents, good street lighting can also reduce the level of street crime that can occur. As time goes by, human activities are not limited by time. Many people choose to be active day and night to pursue efficiency and effectiveness of time. Apart from playing an important role in various social activities, street lighting is also very important for the sustainability of the traffic system. In this case, the case that occurred on the Kertajati – Kadipaten road was that there was no adequate street lighting. This reduces visibility and also the driver's safety level at night. This research aims to evaluate the location of the Kadipaten – Kertajati road, which does not yet have a good street lighting system, and see the impact on motorists. This research was located on the Kertajati – Kadipaten highway, more precisely on the Babakan Anyar village highway, Kadipaten – Monjot Bridge. The research method used in this research is a qualitative method with perception analysis. The parameters used are the respondents' perception of the importance and satisfaction with street lighting on this road, using a scale of 1 to 5 from not important to very important and not satisfied to very satisfied. Data was processed using the Importance Performance Analysis (IPA) method. Data collected from 40 respondents was divided based on age, gender, and vehicle used when crossing the Kertajati – Kadipaten road. From the results of the questionnaire, the majority of gender who travel the Kertajati – Kadipaten road are women. The age range of the majority who cross the Kadipaten – Kertajati road is ≤ 20 years, while those who rarely cross this road are > 60 years. Meanwhile, the most widely used vehicle is a motorbike.

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 well-lit and safe roadway is a crucial factor in ensuring the safety and comfort of road users. This research presents an in-depth analysis of traffic lighting on Jalan Siliwangi Kadipaten-Majalengka through a comprehensive case study. The main focus of the study was to understand the impact of lighting levels on road user behavior concerning infrastructure conditions and lighting aspects. The research methodology involved a field survey that included measuring light intensity, monitoring the type of lights used, and evaluating infrastructure conditions related to street lighting. In addition, a questionnaire from road users was also conducted to obtain their perceptions and experiences regarding traffic lighting along the road. The results show that there are variations in the level of illumination on different parts of the road, which may affect the level of alertness of road users. The analysis of road user behavior also provides insights into the direct impact of lighting conditions on speed, distance judgments, and responses to traffic situations. Based on these findings, the research provides recommendations for the improvement of the street lighting system by considering more efficient use of lights, regular maintenance, and adequate infrastructure adjustments. This research is expected to contribute significantly to the development of strategies that can improve road user safety and comfort on Jalan Siliwangi Kadipaten-Majalengka, as well as provide a foundation for further research in the traffic lighting domain.

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

Majalengka is one of the cities in West Java impacted by the rapid growth of private vehicle numbers. One place in Majalengka that often experiences traffic congestion is the intersection of three markets and the terminal in Rajagaluh. This road connects to Cirebon and tourist areas in the Sindangwangi District. This happens for several reasons, including the significant number of side obstacles along the road around the intersection. Side obstacles at this intersection include street vendors, parked/stopped vehicles, and pedestrians. This research aims to determine the road service level through field surveys at the junction of the three markets and the Rajagaluh terminal. The research methodology employed in this study is qualitative. The use of this qualitative method is interrelated, involving data collection, data grouping, data validation, and finally, data analysis, allowing the emergence of new theories and insights. This research was conducted at the unsignalized intersection near Rajagaluh Market and Terminal in Majalengka Regency. This unsignalized intersection is a junction for inter-district routes located near the terminal and market. Based on the table above, it is found that in the northbound direction, the level of road service is average during the morning and afternoon, while it is classified as high during the evening. In the westbound direction, the level of road service is mild during the morning and afternoon, and during the evening, it is classified as high. The road service level in the eastbound direction is similar, average during the morning and afternoon, and increased during the evening. Therefore, according to the author, the government must improve to anticipate the high traffic volume that will lead to congestion in the future. Based on the study, side obstacles are still relatively low to average. However, this does not mean it will be a benchmark in the future. It is possible that in the coming years, these side obstacles will increase, leading to congestion.
