Abstract

In Indonesia, there are still many level crossings, namely between railways and highways. This will cause congestion, in the form of queue length of vehicles that stop due to the gate closing at the railway level crossing. In addition, level railway crossing located near a signalized intersection can also affect the performance of signalized intersections. This is due to the queue length of vehicle that can interfere with intersection. Based on the problem, it is necessary to build two models. The first model is between the gate closing time at level crossing with the length and speed of the train using multiple regression method. The second model is between the gate closing time at level crossing and the queue length of vehicles using a simple regression method. The result of first model shows that the gate closing time at level crossing has a positive relationship with the length of train and a negative relationship with the speed of train. The relationship among these three variabels is y = -2.083  + 0.637   + 249.930. Y is described as the gate closing time at level crossing, while x1 is the speed of train and x2 is the length of train. While the result of second model regarding the relationship between the gate closing time at level crossing with the queue length of vehicles has a positive effect in each direction. The relationship between two variabels is y = 1.2329x + 84.725 for East Jagir Wonokromo Street from east to west direction and y = 0.5176x + 24.44 for East Jagir Wonokromo Street from west to east direction. Y is described as the gate closing time at level crossing and xis described as the queue length of vehicles.

Abstract

Development of ports in the Lamong Bay may result in changes in flow pattern and velocity. In order for such development does not cause a big impact analysis should be made based on the understanding of the physical processes that will occur. This study examined the flow pattern and velocity of Lamong Bay. Existing model simulation results indicate that the direction of motion of the water flow to the front line of Gresik Ports were more integrated with the dominant direction were Northwest - Southeast, whereas in front of the Port of Tanjung Perak flow direction were dominated by West - East. The findings also suggest the direction of movement of currents in the Lamong Bay were more spread and dominated by the movement parallel to the contour of the coastline.

Abstract

Awareness about driving safety is still lacking among motorcycle users. As the provincial capital of East Nusa Tenggara (NTT), Kupang city accounts for the largest number of accidents in NTT with 70% of the total accidents involving motorcycles. It is important to measure the extent to which riding characteristics affects and causes road accidents since humans as the riders are the main factor in traffic accidents. A questionnaire was distributed to the motorcyclists. The data collected from 212 respondents was analysed with the multivariate logistic regression method. The analysis result states that the motorcycle mileage and the motorbike ownership hold the most influence on the incidence of motorcycle road accidents, where the further the motorcycle riders travel, the higher the probability of them to get involved in a road accident. Meanwhile the more units of motorcycle owned, the lower the probability of them to get involved in a road accident.

Abstract

The Surabaya City Government seeks to provide adequate public transportation such as the Bus. The current condition on the Gunung Anyar - Kenjeran route is that there is no intermodal connectivity, so it is hoped that adequate intermodal connectivity will increase the demand for buses operating on the Gunung Anyar - Kenjeran route. For this reason, this research was conducted to plan the Microbus Stop as a stop location if the Microbus is to be used as a feeder for the Bus and determine the range of Microbus Stop services to meet the needs of the community. One of the locations chosen for this research is the Gunung Anyar - Kenjeran route, this is because this route is the route with the lowest number. Activities carried out to complete this research include conducting surveys of people who are active on and through the gunung anyar - kenjeran route, planning the alternative Microbus Stop location based on demand and infrastructure data and analyzing service coverage using the service area method. From the results obtained, it was found thatd majority of community made the move from Rungkut Sub-District to Gubeng Sub-District and Genteng Sub-District to Wonorejo Sub-District. Alternative Microbus Stop locations is divided into 2 schemes, namely demand-based and infrastructure-based. The demand-based Microbus Stop Scheme has 97 stop points while the infrastructure-based Microbus Stop scheme has 1270 stop points. Based on the results of the analysis of the service coverage of Microbus Stop, it shows that the infrastructure-based scheme has a better service area that meets community expectations, namely 5299.99 ha compared to the demand-based scheme which is only 1873.73 ha. The thing that causes the demand-based scheme to have a small service coverage area is due to the lack of demand data in Bulak District.

Abstract

The hospital is one type of land use utilization which could cause vehicle attraction. It is estimated that the existence of the new Ar-Rozy Hospital would become a trip attraction. For this reason, it is necessary to conduct research to anticipate the magnitude of the movement attraction which would occur in the future due to the existence of the new Ar-Rozy Hospital. This study uses trip generation analysis at 3 existing hospitals located around downtown Probolinggo. The primary data used is a survey of vehicles entering and leaving the hospital, and the secondary one is data consisting of the number of polys, the number of practicing doctors, the number of medical staff, land area, number of rooms, number of beds. The result shows that all independent variables affect the occurrence of vehicle attraction. The best model suitable for representing the conditions of the hospital vehicle attraction is chosen based on the results of a significant regression model and consideration of the highest R2,  multicollinearity, and normality test, the best model is : Y = 91.754 + 0.623 medical staff R2 = 0.991.

Abstract

Kualanamu Airport railway transportation has yet to become the public's leading choice for commuting to Kualanamu Airport because, according to the public, the rates set are still relatively expensive. So, further research is needed on the level of passenger satisfaction, ability to pay (ATP), and willingness to pay (WTP) so that tariffs can be determined according to people's ability and willingness to pay. The method used in this research includes distributing questionnaires and interviews using stated preference techniques. The methods used in this research are the importance-performance analysis (IPA) method and the household budget method. The main priority for the level of satisfaction that needs to be improved is the attribute in quadrant 1 (A), namely the time interval between Kualanamu Airport train, Kualanamu Airport train operational schedules, and Kualanamu Airport train ticket prices. The ability to pay (ATP) for train users at Kualanamu Airport is IDR 79,000. Willingness to pay (WTP) from Kualanamu Airport train users is IDR 49,000.

Abstract

Mikrotrans is a means of transit that supports Transjakarta buses and serves residential neighbourhoods. However, travellers have lodged several concerns about the mikrotrans service's facilities and infrastructure. These concerns include drivers failing to stop at bus stops, drivers driving at excessive speeds, facility damage, inconvenient passenger wait periods, and a lack of bus arrival information. Aside from that, the bus stop lacks operational information, the bus stop pole is damaged, and the distance between bus stops varies. Using the customer satisfaction index approach and IPA-Kano integration, this study examines the operational performance of the Jak Lingko mikrotrans in terms of user satisfaction. The research findings revealed a 71,61% user satisfaction index in the satisfied group. However, all assessment attributes have negative gap values, resulting in a satisfaction score that fails to match user expectations. Based on the IPA-Kano integration analysis, three fatal category qualities were identified as high priority for service improvement. The fatal category attribute is that the driver drives the vehicle if the passenger is seated and/or both of the passenger's feet have touched the ground (A7), the vehicle's stopping time is adjusted to coincide with the completion of the passenger boarding and alighting process (A14), and there is signage, route information boards, the bus name, and the bus stop number (A22).

Abstract

Traffic accidents are unexpected and undesirable incidents that occur on the highway, resulting in damage and casualties. Traffic accidents occur due to several contributing factors, including driver behavior, road conditions, technical errors in vehicles, and environmental conditions. Based on several studies, motorcycles are the vehicles most frequently involved in traffic accidents. Jember is one of the districts in East Java with a high number of motorcycle accidents. Based on data from 2017 to 2019, motorcycle traffic accidents in Jember reached 3,543 cases. Most of motorcycle riders involved in accidents in Jember are young riders. Young riders are considered to lack proper driving attitudes. This study was conducted to determine the relationship between driving behavior and accidents in Jember District among young motorcycle riders using structural equation modeling (SEM). The primary data used were survey results with respondents consisting of motorcycle riders aged up to 24 years old residing in Jember District. There is also supporting data in the form of accident data that occurred in Jember District from 2018 to 2022. Using that method, the results showed that driving behavior variables significantly influencing traffic accidents are traffic violations and stunts. The traffic violations variable has an influence of 0.840. Meanwhile, the stunts variable has an influence of 0.267.
