<p>The increase in urban transportation in the 2000s era was very high. The use of motorized vehicles during the pandemic has decreased slightly with the government's ban on traveling out of town, including the 2020 homecoming and 2021 homecoming. Most people who travel are in the city center, including the city of Bogor and Bogor district. The travel patterns are very diverse, but most use public transportation and private transportation in addition to freight transportation with a fairly high intensity, especially at night. The purpose of this study was to obtain the LoS value at the signalized intersection of the three arms of the Salabenda intersection. The three-arm Salabenda intersection is the border between Bogor regency and the city of Bogor, so this intersection is one of the busiest and most densely populated intersections beside the Ciawi intersection in the north. The Salabenda intersection has become more congested with the opening of the Section IIIA Toll Road so that the traffic load shifts from Jl. KH. Sholeh Iskandar to this toll road, so that the intersection will have a higher traffic intensity. From the three observations and data collection in the field, it can be seen that in the afternoon it has a very high LoS, namely E. Followed by a LoS D level in the afternoon and in the morning LoS is still in the form of C. So it is still safe to use in the morning with a recommended level. The LoS E condition is a condition where the intersection has a degree of saturation of 0.926, which is almost close to 1, exacerbated by high side resistance activity.</p>

Bandung is one of the major cities in Indonesia. The lower middle class is greatly helped by public transportation. Angkot is transportation that is close to the people. However, public transportation services that are less organized can make people switch to using private transportation. This actually has a bad impact on traffic. Thus, there need to be improvements in public transportation in the city of Bandung. One-way roads in the city of Bandung are also the cause of many angkot routes. The choice of public transportation users to choose an efficient angkot route. Efficient here means a short path so that the travel time to the destination is minimal. In the previous article, the Cicaheum Ciroyom and Ujung Berung ITB angkot routes were obtained using the Greedy algorithm. In this discussion, the algorithm that can be used to determine angkot routes in Bandung is the Min-Plus algorithm. After being compared between the Greedy algorithm and the Min plus algorithm, the resulting angkot algorithm is better obtained by the Min Plus algorithm.

As cidades médias se destacam pelo seu caráter dinâmico, centralizador, atrativo de mercadoria, serviços e pessoas. A cidade de Montes Claros, localizada no norte de Minas Gerais, tem demonstrado tais características através do intenso fluxo de viagens demandado pela população aos Polos Geradores de Tráfego. Nesse cenário, necessita-se de um modo capaz de suprir a carência de transporte das pessoas, de maneira segura, econômica, sustentável e racionalizando. O ônibus, gerido por meio de diretrizes do Estado, se apresenta como melhor opção em relação aos automóveis particulares, uma vez que reduzem congestionamento e exercem papel social. Nessa perspectiva, o presente trabalho analisa a acessibilidade por transporte público coletivo ao polo gerador de tráfego (Escola Estadual Professor Plínio Ribeiro), localizado na Avenida Mestra Fininha, número 1225, bairro Jardim São Luiz, em Montes Claros – MG. Essa análise leva em conta o tempo de viagem (tempo de espera e tempo de percurso) por transporte público com ligação direta a escola e utiliza Sistemas de Informações Geográficas para armazenamento, processamento e espacialização dos dados coletados. A partir daí, sugere-se o nível de acessibilidade dos moradores da cidade de Montes Claros à escola Estadual Professor Plínio Ribeiro, o qual se mostrou com melhores resultados na área central e, quase sempre, reduziu-se à medida que se aproximava das regiões periféricas.

[ID] Permasalahan transportasi seperti kemacetan, polusi udara, kecelakaan, antrian maupun tundaan bisa di jumpai dengan tingkat kualitas yang rendah maupun besar. Permasalahan tersebut sering kita jumpai di beberapa kota di Indonesia termasuk di Pekanbaru. Beberapa titik kemacetan yang terjadi di Kota Pekanbaru saat pagi dan sore atau jam sibuk khususnya pada simpang bersinyal di jalan Sudirman – jalan Gajah Mada yang merupakan intesitas yang besar selalu dilewati lalu lalangnya kendaraan yang melewati dilokasi tersebut. Metode perhitungan analisis dan perencanaan yang di gunakan adalah metode Manual Kapasitas Jalan Indonesia 1997 (MKJI 1997) agar dapat mengetahui seberapa besar fungsi dari sistem kendali waktu tetap dalam menghindari kemacetan serta mengurangi resiko kecelakaan pada simpang akibat konflik lalu lintas. Dari hasil analisis menggunakan perhitungan MKJI 1997 di dapat kapasitas terbesar adalah 2375,94 smp/jam pada ruas jalan arah selatan. Panjang antrian  maksimum adalah 171,171 m pada ruas jalan arah utara terjadi antrian panjang  pada  kondisi lalu lintas dan Tunda an rata-rata sebesar 1440,159 det/smp. Sehingga tingkat pelayanan simpang pada kondisi jam puncak masuk dalam katagori F/buruk sekali (>60 detik/smp). Pada kondisi eksisting ketiga simpang sudah mendekati kinerja yang jenuh, dengan hasil derajat kejenuhan 1,00 (DS > 0.85) arah ruas jalan utara. Waktu Siklus Sinyal pada persimpangan tersebut adalah 95 detik, ini termasuk kedalam tipe pengaturan 4 fase 80-130 (MKJI,1997). Dari hasil analisis tersebut peneliti menyarankan perlu mengidupkan kembali countdown timer pengendara dapat memulai start berangkat lebih awal, hal ini dapat ini dapat mengurangi waktu hilang dan mengurangi kemacetan. [EN] Transportation problems such as congestion, air pollution, accidents, queues and delays can be found with low or large quality levels. We often experience this problem in several cities in Indonesia, including in Pekanbaru. Some congestion points that occur in the city of Pekanbaru in the morning and evening or rush hour, especially at the signal intersection on  Sudirman street – Gajah Mada street which is a large intensity always passing the negligence of vehicles passing through the location. The method of calculation of analysis and planning used is the method of the Indonesian Road Capacity Manual 1997 (MKJI 1997) in order to find out how much the function of the fixed time control system is to avoid congestion and reduce the risk of accidents due to traffic conflicts. From the results of the analysis using the MKJI 1997 calculation, the largest capacity is 2375.94 smp/hour on the southern road segment. The maximum queue length is 171,171 m on the northern road segment, there is a long queue in traffic conditions and the delay is an average of 1440,159 det /smp. So that the level of service intersection at peak hour conditions is in the category F / very bad (> 60 seconds / junior). In the existing conditions the three intersections are close to saturated performance, with the result of a degree of saturation of 1.00 (DS> 0.85) in the direction of the north road segment. The Signal Cycle time at the junction is 95 seconds, this is included in the 4 phase 80-130 setting type (MKJI, 1997). From the results of the analysis, the researchers suggest that it is necessary to revive the driver's countdown timer to start the start early, this can reduce the lost time and reduce congestion.

This article explains the low noise that originates from the volume of public transportation and private transportation during COVID-19 (few vehicles are passing). The method used is surveying traffic data in the field (the noise is measured when the vehicle passes the roadside of the survey location), including when COVID-19 hits the city. This study refers to several cities, including the city of Bogor as the object of research. Traffic movements have slowed down due to the COVID-19 outbreak. This field method is effective in describing the current traffic conditions. In the findings, the indicator used to determine the vehicle volume noise contributes 12.10% of the calculation result of y = 70.718 + 0.013 x 1. The result is a significant effect seen on sound level meter (SLM) 3, with an increase of 70.718 dBA, distance from the sidewalk to the nearest building wall of 10.24 m, and vehicle speed of 80 km/hour. The results of this study will enhance the development of science and engineering technology as a contributor to cooperative support of government policies to comply with health protocols in this COVID-19 era.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.
