Abstract

For developing countries, the implementation of sustainable transportation systems is crucial to involve substantial investments. Mobility in Indonesia can have an impact on both origin and destination areas. This research aims to determine the distribution of schools that are not served in the city of Semarang. Consequently, an identification can be made to formulate a recommendation for the development of operational routes for the BRT Trans Semarang to enhance connectivity between other transportation modes on routes with high demand. A quantitative descriptive analysis was performed to assess BRT Trans Semarang through utilizing government documents, news, and official websites, followed by interviews, FGD, and direct surveys with BRT users and providers. It is known that there are a number of schools that are not served in 16 districts of the city of Semarang, namely Semarang West (51), Semarang South (25), Semarang Central (41), Semarang East (36), Semarang North (40), Banyumanik (49), Tembalang (36), Gunung Pati (16), Pedurungan (50), Gajah Mungkur (31), Mijen (26), Candisari (21), Tugu (14), Gayamsari (25), Ngaliyan (27), and Genuk (29). Feeder Route 3 is popular but has limited capacity. 79.20% of respondents support extending BRT routes to their schools.

Abstract

Transportation safety in Indonesia reflects its culture and modernity, but the high rate of traffic accidents indicates significant challenges. Data from IRSMS and Polda Metro Jaya reveal an increase in accidents and traffic violations, reinforcing the need for effective law enforcement. The implementation of ETLE, supported by Law No. 22 of 2009 on Road Traffic and Transportation and Law No. 19 of 2016 on Electronic Information and Transactions, is a strategic effort to improve law enforcement. However, its effectiveness in Jakarta context still requires in-depth evaluation. This thesis focuses on the psychological factors in the use of ETLE using the Theory of Planned Behavior. The analysis results show that factors such as self-confidence, anxiety, and influence of other drivers significantly contribute to the tendency of violations. With a beta coefficient of 0.029 and a t-statistic of 15.776, a holistic approach to road safety is required, involving infrastructure, law enforcement, driving education, and psychological aspects, to achieve the WHO target of reducing accidents by 50% in the Decade of Action for Road Safety 2021-2031.

Abstract

In DKI Jakarta, despite the extensive infrastructure development, there has been a significant decline in the usage of public transportation. This can be attributed to the inadequate quality of the services provided. Various studies have highlighted the significance of evaluating the quality of service in public transportation to ensure passenger satisfaction and attract new users. However, there is no agreement on the most effective methodology and suitable indicators for conducting such analyses. In addition, there is a growing recognition of the importance of promoting gender equality in multimodal public transportation (MMPT) and understanding gender differences and perceptions of MMPT services. A case study was carried out in DKI Jakarta, the capital of Indonesia, to analyse the influential indicators of the quality of MMPT. The analysis used the Importance Performance Analysis (IPA) combined with the Tarrant and Smith procedure. These indicators greatly impact the perception of MMPT services for both genders. Safety against crimes, facilities for disabled people, pregnant women, and senior citizens, announcements in the required language, clarity in travel-related information, and availability of seats inside vehicles are the most influential indicators of the quality of the services. However, there are significant differences in how women and men perceive the importance and performance of indicators related to seating availability, coordination between transport operators, and passenger information.

Abstract

Economic growth involves massive movement of logistics, where goods transported by land become the main choice by supplier. One of them being the main access for connecting Java and Sumatera is the Tangerang – Merak toll road. An increase in traffic volume occurs every year, followed by additional problems such as congestion which obviously affects traffic performance. Given this reason, it is necessary to evaluate traffic performance through parameter assessments, which are the degree of saturation and travel speed. This research was carried out on the Tangerang - Merak toll road section KM 32,300 to KM 35,500 towards Jakarta for one week using traffic CCTV recordings, then selected on 17 April 2024. The calculation results obtained for each average weighted value for the degree of saturation (Ds) at 0.36 and average of the Space Mean Speed is at 33.08 kph. Based on traffic performance analysis, the volume parameter does not indicate a problem, and is included in the LOS A category. However, the travel speed parameter shows an issue and included in the LOS F category. This will be the focus problem within the scope of the research. On the other side, traffic composition which includes variations in the number of vehicles per time and type of vehicle. Given this kind of variation, a Passenger Car Unit value is needed that can equalize the existing different vehicle types into a uniform standard, including who commit over dimensional violations. Where the value of passenger car equivalent of an over-dimensional vehicle is changing, it is necessary to re-calibrate the emp value. Researchers used the Volume Delay Function formula to calculate travel time, then explore a combination of emp values using the dynamic programming method by comparing survey travel time with the simulation one. The difference between the PKJI standard value and the calibrated pce value proves the problem of these vehicles commit over dimension violations on the Tangerang – Merak toll road. For this reason, it is hoped that this research which evaluate traffic performance, travel time and passenger car equivalent values, can be used as a basis for further policy making to improve the performance of the Tangerang – Merak toll road.

Abstract

The research on optimizing Equivalent Motorized Passenger Car Unit (EMP) values for motorcycles in Jabodetabek addresses the pressing traffic challenges in Indonesia's largest metropolitan area. With rapid population growth and increasing motor vehicles, accurate traffic flow modeling is crucial. Motorcycles, dominant in Jabodetabek's transport, are often misrepresented by EMP values equivalent to cars, leading to inaccurate traffic estimates. Adjusting EMP values, especially in macroscopic modeling, is imperative for precise transportation planning. This study explores the necessity of recalibrating EMP values for motorcycles, crucial for sustainable development and future transportation technology integration. By analyzing traffic dynamics and adjusting EMP values, the research aims to provide more accurate depictions of traffic conditions, essential for effective policymaking and infrastructure planning. Results indicate a clear correlation between traffic density and motorcycle efficiency, emphasizing the need for tailored EMP values. This research offers insights for improving transportation planning and addressing future metropolitan traffic challenges.

Abstract

The rapid growth of motorcycle vehicles coupled with inadequate traffic discipline contributes to an escalating rate of traffic accidents and casualties. This study investigates the efficacy of auxiliary road markings in enhancing traffic safety and intersection performance along Lieutenant Sutopo Street, Promoter Street, and Boulevard BSD East in South Tangerang, Indonesia. Employing the Traffic Conflict Technique (TCT), the research evaluates safety enhancements and service level alterations subsequent to the installation of road markings. Preliminary observations highlight significant safety concerns and traffic conflicts at the intersection. Consequently, auxiliary road markings are strategically installed to regulate driver behavior, enhance lane discipline, and improve visibility. Post-installation observations revealed a significant decrease in total vehicle conflicts, though the percentage of severe conflicts slightly increased. Initially rated as Level of Service (LOS) F with high delays, the LOS remained the same post-marking installation but with reduced delays. Further cycle time adjustments improved the LOS to E, indicating a substantial overall reduction in delays. The findings suggest that although auxiliary road markings effectively reduce traffic conflicts and improve intersection performance, additional measures are necessary to address the severity of these conflicts. The study offers valuable insights into the effectiveness of road safety interventions, supporting broader strategies for improving traffic management and safety in urban areas.

Abstract

In its implementation, the role of coal transportation infrastructure is important in supporting the mining industry in Jambi City. However, it also causes various complex problems; one of them is traffic congestion on arterial roads in Jambi City. In May 2023, the Jambi Regional Police of the Republic of Indonesia issued a notification letter to stop the mobilization of coal transportation in Jambi Province. The policy caused several coal companies to switch their transportation method to shipping in order to continue operating, while several other companies stopped operating until an indeterminate time. Therefore, this study aims to compare traffic performance before and after the implementation of the policy on Jambi City arterial roads, especially on Talang Duku Port Road and East Ring Road II. The method used was a comparative analysis of the degree of saturation before and after the enactment of regulations on the prohibition of coal truck operations. The results of this study show the importance of traffic management as one of the solutions to reduce traffic congestion. Nevertheless, other alternatives are still needed to support the smooth operation of coal transportation activities.

Abstract

Vehicle speed consistency plays a crucial role in maintaining traffic safety, with speed limits set to reduce accident fatalities. While the direct impact of speed limits on vehicle speed is minimal, their implementation significantly influences driver behavior, with about 85% of drivers complying with speed limits. However, variables such as traffic volume, weather conditions, and travel urgency often cause drivers to be inconsistent in adhering to these limits, increasing accident risk. On the Mojokerto-Surabaya toll road, data from Traffic Corps and Jasa Marga recorded 193 accidents with 101 fatalities from 2018 to August 2023, mostly caused by driver behavior such as excessive speed. This study analyzes the relationship between speed consistency and accident probability on this road, highlighting accident issues due to speed violations and inconsistency at ramp off/on locations. Results show the importance of toll road infrastructure considering vehicle volume, identifying accident blackspots, and implementing urgent speed management as key factors in improving safety on the Surabaya-Mojokerto toll road. The findings emphasize the need for better traffic management and speed regulation to reduce fatal accident risks.

Abstract

Mobility has become a crucial factor in transportation management, especially in the tourism sector. It is a key indicator of the performance of transportation infrastructure and people's response to it. To evaluate mobility in tourist areas, there is a need for tools to represent its value. In this study, the concept of an index as a measure of performance is applied, gathering information into a simpler and more mutually agreeable form. The cultural heritage sites of Borobudur, Prambanan, and Ratu Boko are chosen as an ideal study location due to their popularity internationally. Given the limitations of previous research on mobility indexes in tourist areas, the Sustainable Urban Mobility Index (I_SUM) framework is used to develop the variables. To avoid bias, this study utilizes expert opinion methods to assess necessary and unnecessary variables in achieving the index. Eight individuals with expertise and experience in transportation and tourism are selected as respondents. Furthermore, the expert evaluation results are processed using the Content Validity Index (CVI). The outcome is 26 variables that meet the validation test out of a total of 32 previous variables, which are divided into five domains, covering accessibility, social aspects, transportation infrastructure, traffic cycle, and transportation systems.

Abstract

Jakarta International Container Terminal (JICT) in Tanjung Priok Port , which serves export and import containers, can serve up to 5500 TEUs daily. However, no more than 1% of the total containers are transported by freight trains, meaning that 99% of container distribution from industrial areas is carried by trailer trucks. This condition causes a long queue at the container terminal entrance, resulting in delays in the services as well. Currently, Tanjung Priok Port is connected to rail transportation from Cikarang dry port with the frequency of twice a day with 30 flatcars (FC) for each trip. The capacity of one series of freight trains from Cikarang dry port to Tanjung Priok Port can reach 30 Feus or 60 Teus. However, the container distribution using freight trains is still less optimal because of the double handling at the JICT emplacement which is located outside JICT and the use of trailer trucks to move the containers from the area to JICT. The cost of transporting export and import containers always increases year by year because of the slow transportation due to inefficiency of the container depot location in Tanjung Priok area. In this research, the method used to determine the efficiency of container transportation is divided into three scenarios. The first scenario is when the container is fully transported by truck from the industrial area. The second scenario is when the container is transported by train and handled twice while entering JICT. Finally, the third scenario is when the JICT emplacement is located inside the JICT area, changing the business process of containers coming in and out, needing no stacking in the JICT container yard, relocating the container depot placement, consolidating containers, and automating equipment at JICT to reduce the cost and time of containers for export and import. After analyzing the costs and time of the three scenarios, it was found that the third scenario could reduce travel costs and shorten container time when exporting and importing. The 3rd scenario can reduce the cost by almost 50% from the 1st and 2nd scenarios due to container consolidation.
