KERUGIAN BBM AKIBAT TUNDAAN DAN PANJANG ANTRIAN DI PERSIMPANGAN JALAN RAYA DENGAN REL KERETA API SEBIDANG (Studi Kasus Jalan Hasanudin Semarang)

Due to the high mobility of those passing by and the presence of trains that cross the intersection between the highway and the railroad, also known as level crossings, Jalan Hasanudin experiences heavy traffic during rush hour. Additionally, because of the large volume of train traffic at the Poncol station and the proximity of this intersection to the station, there is frequently a buildup of vehicles at the level crossing on Jalan Hasanudin. As a result, researchers will determine how Jalan Hasanudin Semarang performed. After conducting research, it was discovered that the highest vehicle queue length occurred on Monday, February 27 2023 from Jalan Hasanudin - Imam Bonjol at closing time 16.45 with a queue length of 123 meters and the highest stop delay occurred on Saturday, March 4 2023 from the direction of Jalan Hasanudin - Imam Bonjol with an average stop delay duration of 372.00 seconds. Therefore, the occurrence of long lines led to fuel losses for the drivers; their total gasoline loss over the course of the three research days was IDR 886,550.7. The researchers offer recommendations based on the findings of the research analysis to control street vendors and people near railroad tracks and railroad crossings that result in side barriers and long lines during stop delays, install traffic signs like those that prohibit stopping, prohibit parking, and prohibit raising and lowering passengers on roads, and so that there is no congestion along Jalan Hasanudin and around railroad crossings

Centerline Curbing Treatment at Railroad Crossings for Improved Safety

The objectives of this research were to study unsafe actions of motor vehicle drivers at railroadhighway grade crossings, to evaluate centerline barriers in reducing those unsafe driver actions, and to note any maintenance or other issues with the barriers. Driver actions were observed at two railroad crossings before and after installation of centerline barriers. A comparison of observed driver actions in the pre- and post-barrier periods provided information on the effectiveness of the barriers in reducing unsafe driver actions while periodic inspection of the centerline barriers provided information on maintenance needs. A major concern of the Nebraska Department of Roads is the potential for crashes at railroad-highway grade crossings resulting from unsafe actions of motorists such as, rushing the gates to beat an oncoming train or playing “chicken” with an approaching train, among others. Playing “chicken” refers to intentional standing of a motor vehicle on railroad tracks and only moving when the train hits the brakes. Crashes at railroad-highway crossings may not necessarily involve trains as some driver actions (e.g., backing up, and U-turns) may result in crashes involving motor vehicles only. In this research the crossing at North 141st Street in the City of Waverly, NE and the crossing at “M” Street in the City of Fremont, NE were monitored with the help of day and night vision cameras and digital video recorders. Motor vehicle driver actions were observed whenever the gates were down and instances of unsafe actions noted. In an effort to reduce gate rushing and other unsafe motorist actions, the researchers installed flexible rubber and plastic barriers on both sides of the crossings along roadway centerlines to prevent motorists from going around the gates. The actions of motor vehicle drivers were monitored in the post-barrier period and compared to the pre-install period using appropriate statistical tools. Results of the comparison show that fewer unsafe driver actions were observed after installation of the centerline barriers. In particular, installation of centerline barriers significantly reduced instances of gate rushing at the two study sites. Centerline barriers are recommended for use at railroad crossings where unsafe driver actions (e.g., gate rushes) are a concern. Damage to the barriers as a result of abuse from roadway vehicles was noted while no snowplowing issues came to the attention of the researchers during the study period. The amount of damage was a function of traffic volume, percentage of trucks, and if sharp turns were involved. Finally, this study revealed instances of pedestrians and bicyclists engaged in unsafe actions at railroad crossings, which are recommended for investigation in a future study

PROGRAM PENANGGULANGAN KECELAKAAN LALULINTAS DI PERLINTASAN KERETA API SEBIDANG DI WILAYAH JAWA TENGAH

One of the transportation problems still faced in the country is the problem of traffic accidents that not only occur on roads and highway intersections, but also those that occur at level crossings between trains and motorized vehicles. Such as the train accident in Silebu Village, Kragilan District, Serang Regency, Banten Province on July 26, 2022 which killed 9 people. In the end, the issue of railroad crossings is not enough to be seen from one aspect of the problem alone but extends to other fields because it involves the various roles of actors, signals/codes, field space, and the morality of the users themselves. The number of railway crossings on the Central Java Regency / City road according to data from the Directorate General of Railways of the Ministry of Transportation in 2022 was recorded at 834 level crossings spread across 23 districts / cities, with details of 476 unguarded crossings and 268 guarded crossings. Starting from this condition, this research was conducted as a premise for Research on Safety Countermeasures Program at Railway Crossings in Central Java, especially both level crossings on provincial roads and on Regency / City roads

Analysis of Policy Issues Relating to Public Investment in Private Freight Infrastructure, MTI Report 99-03

The Norman Y. Mineta International Institute for Surface Transportation Policy Studies (IISTPS) at San José State University conducted this study to review the issues and implications involved in the investment of public funds in private freight infrastructure. After thorough legal research, the project team reached the following conclusions: LEGAL ANALYSIS: The California legislature has the legal power to invest public funds in privately-owned freight infrastructure projects State Highway funds, excepting gas tax revenues, may be used for investment in freight infrastructure projects. Gas tax revenues are restricted to highway use by current interpretations of the California Constitution. A challenge to this interpretation is not recommended. Gas tax revenues may be invested in roadway segments of freight infrastructure projects. RECOMMENDATIONS An analytical system of guidelines should be developed to score and evaluate any proposed freight infrastructure project. Economic development must be included in these scoring guidelines. Public agencies should maintain political contacts in order to control the political short-circuits of the planning process. The California Department of Transportation should develop a Freight Improvement Priority System for the purpose of prioritizing all freight improvement projects

Designing Sustainable Landscapes: Terrestrial barriers settings variable

Terrestrial barriers is one of several ecological settings variables that collectively characterize the biophysical setting of each 30 m cell at a given point in time (McGarigal et al 2017). Terrestrial barriers measures the relative degree to which roads and railroads may physically impede movement of terrestrial organisms. It is derived by assigning an expertderived score to each road/railroad class to reflect the increasing physical impediment of larger roads, and adjusting these scores at road-stream crossings (i.e., bridge or culvert) based either on a custom algorithm applied to field measurements of the crossing structure or predictions from a statistical model (see below for details) to reflect increased passability of terrestrial organisms through the crossing structure. Terrestrial barriers is scaled 0-5, where roads and railroads are assigned values \u3e0 (indicating the relative degree of impediment) and all other cells are assigned 0.https://scholarworks.umass.edu/data/1021/thumbnail.jp
