“…Level of Service (LOS) adalah salah satu metode yang efektif diterapkan untuk merancang dan mengatur pengaturan waktu sinyal di persimpangan. LOS berisi beberapa karakteristik yang terukur dan tundaan adalah salah satu faktor paling signifikan yang perlu dipelajari lebih lanjut (Ye, et al, 2022). Tundaan pelayanan didefinisikan sebagai tundaan yang dialami oleh kendaraan di garis berhenti saat menunggu kesempatan untuk memasuki simpang (Ashalatha & Chandra, 2011).…”

Congestion at the crossroads of Bandung City occurs due to the increasing traffic volume, while the road capacity of Bandung City is quite limited. One of the congestion points at the intersection of Bandung City roads is located at Laswi Street-Pelajar Pejuang 45 Street and Jenderal Gatot Subroto Street. This study aims to identify the performance of traffic flow movements at the intersections of Laswi Street-Pelajar Pejuang 45 Street and Jenderal Gatot Subroto Street after the Laswi – Pelajar Pejuang 45 flyover operates. This study uses a type of quantitative research through analysis of APILL Intersection Performance according to PKJI 2014. Based on the results of the analysis, the average intersection delay is 411,3 seconds/skr to 553,4 seconds/skr. This shows that each approach has an average intersection delay of level of service of F (> 60 seconds/skr) or very bad. This is caused by the intersection cycle time which is too long and not in accordance with PKJI standards in 2014 where the flow of vehicles at the intersection of Laswi Street-Pelajar Pejuang 45 Street is hampered, traffic volume is above capacity, and congestion often occurs for quite a long time. Based on the results of cycle time optimization calculations, traffic flow conditions have increased performance to C (medium) with an average intersection delay value of 16,5 seconds/skr to 19,1 seconds/skr. Abstrak Kemacetan di persimpangan jalan Kota Bandung terjadi akibat volume lalu lintas yang semakin meningkat, sedangkan kapasitas jalan di Kota Bandung cukup terbatas. Salah satu titik kemacetan di persimpangan jalan di Kota Bandung terletak di Jalan Laswi – Jalan Pelajar Pejuang 45 dan Jalan Jenderal Gatot Subroto. Penelitian ini bertujuan mengidentifikasi kinerja pergerakan arus lalu lintas di persimpangan Jalan Laswi – Jalan Pelajar Pejuang 45 dan Jalan Jenderal Gatot Subroto pasca Flyover Laswi – Pelajar Pejuang 45 beroperasi. Penelitian ini menggunakan jenis penelitian kuantitatif melalui analisis Kinerja Simpang APILL menurut PKJI Tahun 2014. Berdasarkan hasil analisis, tundaan simpang rata - rata yaitu sebesar 411,3 detik/skr sampai 553,4 detik/skr. Hal ini menunjukkan bahwa masing – masing pendekat memiliki tundaan simpang rata – rata tingkat pelayanan senilai F (>60 detik/skr) atau buruk sekali. Nilai ini diakibatkan oleh waktu siklus persimpangan yang terlalu lama dan tidak sesuai dengan standar PKJI tahun 2014 di mana arus kendaraan pada persimpangan Jalan Laswi – Jalan Pelajar Pejuang 45 terhambat, volume lalu lintas di atas kapasitas, dan sering terjadi kemacetan dengan waktu yang cukup lama. Berdasarkan hasil perhitungan optimalisasi waktu siklus, kondisi arus lalu lintas memiliki kinerja yang meningkat menjadi C (sedang) dengan nilai tundaan simpang rata – rata 16,5 detik/skr sampai 19,1 detik/skr.

“…The influencing factors of accident severity were divided into the driving behavior and driver characteristics for automobiles and two-wheeled vehicles, road characteristics, peak time, and environmental characteristics [19][20][21]. This paper collated the data of automobile to two-wheeler traffic accidents in Guilin, including 24 indicators from four aspects.…”

The purpose of this paper is to analyze the complex coupling relationships among accident factors contributing to the automobile and two-wheeler traffic accidents by establishing the Bayesian network (BN) model of the severity of traffic accidents, so as to minimize the negative impact of automobile to two-wheeler traffic accidents. According to the attribution of primary responsibility, traffic accidents were divided to two categories: the automobile and two-wheeler traffic as the primary responsible party. Two BN accident severity analysis models for different primary responsible parties were proposed by innovatively combining the Kendall correlation analysis method with the BN model. A database of 1560 accidents involving an automobile and two-wheeler in Guilin, Guangxi province, were applied to calibrate the model parameters and validate the effectiveness of the models. The result shows that the BN models could reflect the real relationships among the influential factors of the two types of traffic accidents. For traffic accidents of automobiles and two-wheelers as the primary responsible party, respectively, the biggest influential factors leading to fatality were weather and visibility, and the corresponding fluctuations in the probability of occurrence were 32.20% and 27.23%, respectively. Moreover, based on multi-factor cross-over analysis, the most influential factors leading to fatality were: {Off-Peak Period → Driver of Two-Wheeler: The elderly → Driving Behavior of Two-Wheeler: Parking} and {Drunk Driving Two-Wheeler → Having a License of Automobiles → Visibility: 50 m~100 m}, respectively. The results provide a theoretical basis for reducing the severity of automobile to two-wheeler traffic accidents.

“…The prediction results show that the proposed method in this study can significantly improve the prediction accuracy of vehicle acceleration. Ye et al [23] analyzed the factors affecting the LOS (level of service) of non-motorized vehicles crossing the signalized intersection, aiming at the mixed non-motorized traffic flow of electric vehicles and bicycles in the Chinese metropolis. Liu et al [24] analyzed the complex coupling relationships among accident factors contributing to the automobile and two-wheeler traffic accidents.…”

In Japan, where the birthrate continues to decline, various initiatives are underway to promote traffic safety for children. Although these efforts have helped reduce the number of traffic accidents involving children, an examination of the circumstances under which children were killed or injured in traffic accidents in recent years shows that accidents in which children were riding bicycles accounted for the highest percentage of accidents. We investigated the relationship between the ages of children involved in traffic accidents and violations of traffic laws using traffic accident statistics maintained by the Ishikawa Prefectural Police Headquarters. These records revealed that 16-year-olds were most likely to be involved in traffic accidents. Our analysis of the violations of laws and ordinances with respect to the ages of bicyclists involved in car accidents at intersections found that, of all the age categories, elementary school students had the lowest rate of accidents with no violations and the highest rate of accidents involving a failure to stop. Junior and senior high school students had lower rates of accidents involving a failure to stop than elementary school students. Moreover, at non-intersections, driving safety violations were notably higher for accidents involving bicycling elementary school students than for those in other age groups.
