Transportation problem, either in general or specifically in traffic, is a phenomenon occuring in human life. As the population of city increased, so does the traffic rate. If this is not followed by adequate improvement of transportation infrastructure, an imbalance might occur which will result in traffic jam. It can be seen particularly at Lingkar Tengah – Dr. Leimena road junction connecting Jalan Perintis Kemerdekaan - Dr Leimena road due to driver/rider against the direction. Data analysis and planning using method of road capacity manual (MKJI 1997) and the traffic modelling using PTV Vissim. Based on road performance analysis it is known that DS (degree of saturation) is 0.12 with service level ‗A‘ and average speed ≥23km/h with service level ‗D‘. From the calculation result, modelling is conducted using PTV Vissim modelling. Alternative for handling the intersection is using 2 methods, which are traffic light signaling for 3 phases with immediate straight at west corner and immediate left turning at east corner and bridge closure on Dr. Leimena road. Using PTV Vissim, the result is that intensity of travel time increases about 47.68% and 57.40% on the intersection.

Krian Bypass intersection is a very crowded route because of its location near Sidoarjo and Mojokerto Regencies for the economic distribution of Surabaya City. There needs to be phase regulation, road widening or fly over so that the intersection traffic volume is not getting saturated. As a benchmark is the forecasting of traffic performance carried out for 3 years from 2018 to 2021. Based on the results of forecasting, the Krian Bypass intersection will decrease its DS value by widening the road so that the green time cycle will be low and turn right impact the DS value below 1 (one). The lowest 2018 DS is 1.61, while the highest DS is 2.49. While the lowest year 2021 DS is 2.72, while the highest DS is 4.85. For the solution with the right turn phase for each intersection to the north DS = 1.02, U-RT = 0.82, S = 1.38, S-RT = 0.69, T = 1.24, T-RT = 0.78, B = 1.79, B-RT = 0.04 . The solution for forecasting the flow of Krian Bypass in 2021. The calculation results made with effective width engineering, turn right and green time can reduce the DS value (Degree of Saturation) still shows DS value> 0.75 - 1, then fly over is constructed with a scenario of 20% vehicles through existing and 80% of vehicles through fly over. Year 2021 The impact of fly over shows North DS = 0.4, South = 0.51, East = 0.56, and West = 0.45

The intersection of the Cisalak I toll gate in Depok City is the intersection that connects the road. Ir. H. Juanda, Jalan Raya Bogor, Jalan Gas Alam, and of course the Cisalak I highway exit & exit. By having 6 intersection arms, of course there are many traffic conflicts that occur at the Cisalak I toll gate intersection, one of which is a delay in the intersection arm long so that congestion in each intersection during rush hour always occurs and coupled with the cycle time of the traffic light which takes quite a long time so the long queue occurs. The purpose of this study is to know more about the performance of the traffic. The method used is to observe directly to the research location by observing the volume of vehicles with various types, the phase current of the vehicle passing at the intersection, and the cycle time of the traffic light, and by using Vissim software as modeling and getting the results of the count. The results of the study found capacity on the Bogor Highway (Jakarta direction) with a total of 771.69 , Jalan Ir. H. Juanda is 542.92, Bogor Highway (Bogor direction) is 612.21, and Cijago / Cisalak & Natural Gas Toll Road is 538. and the value of degree of saturation in each intersection is Highway Bogor (direction Jakarta) amounting to 2.96, Jalan Ir. H. Juanda is 3.52, Bogor Highway (Bogor direction) is 2.77, and Cijago / Cisalak & Gas Alam Toll Road is 2.95, so the level of service results in all F crossing arms which means the congestion condition takes up the duration long enough.

AbstractThis article analyses the implications of the Forced Labour Convention of 1930 on colonial labour policies for road labour carried out under chiefs in the Gold Coast. The British colonial administration implemented a legal application of the convention that allowed the continuation of the existing system of public works. In the Gold Coast, the issue of road labour was most prominent in the North, where chiefs maintained the majority of roads. Indirect rule became crucial in retaining forced labour in compliance with the convention. This article focuses on “hidden strategies” of British colonialism after 1930, contrasting studies of blatant cases of forced labour. The analysis is based on a close scrutiny of the internal discourse among colonial officials on the question of road labour and the Forced Labour Convention.

This paper presents the research results of applying the combined method of probabilistic statistical approaches, energy density spectral correlation, two-dimensional filtering in dynamic sliding windows, full horizontal gradient and heterogeneous axis tracking method to process and interpret the Bughe gravitational anomaly field in central area Vietnam. The calculation results have shown the superiority of the twodimensional filter in dynamic sliding windows compared to the filters in fixed windows in GEOSOFT software, GMT software. According to the physical characteristics of the field, the study area was divided into 13 homogeneous classes, this result is consistent with the geological-tectonic data in the area. In the north and northeast, the stabilized rock layers are characterized by homogeneous layers that extend in the northwestsoutheast direction. In the south and southwest, there is complex tectonic activity characterized by high density rock layers overlain by low density rock layers in each fault band with different directions of development. This suggests that there may be deeply buried mineral deposits of magmatic origin in central area Vietnam.

This research will redesign the flexible pavement on the Kalihurip-Cikampek toll road using three flexible pavement design methods, namely the 2002, 2013 and 2017 methods, and analyze the structural responses that occur in the form of horizontal and vertical strain, the main components. In calculating the value of repetition of permits against fatigue damage (Nf) and groove cracks (Nd), it is processed using the KENPAVE program. Furthermore, the calculation results of the flexible pavement thickness, the value of repetition of permits against fatigue damage (Nf) and groove crack damage (Nd) were compared from the three methods. The method used is mechanistic-empirical. Primary data is obtained from the Ministry of Public Works and Public Housing and LHR0 starting in 2020, taking into account traffic growth from 2020 to 2035, as well as secondary data assumptions by referring to previous regulations and research. The results of this study indicate that the 2002 method produced the largest pavement thickness, while the 2013 and 2017 methods produced relatively the same pavement thickness. However, the 2002 method produced the largest repetition of permits against fatigue damage (Nf) and groove cracks (Nd). So it can be concluded that the 2017 method produces a better design. ABSTRAKPenelitian ini akan mendesain ulang perkerasan lentur pada Jalan Tol Jakarta-Cikampek ruas Kalihurip-Cikampek menggunakan tiga metode desain perkerasan lentur yaitu metode 2002, 2013, dan 2017, serta menganalisis respons struktral yang terjadi berupa regangan horisontal dan vertikal, komponen utama dalam menghitung nilai repetisi izin terhadap kerusakan fatik (Nf) dan retak alur (Nd), diolah menggunakan program KENPAVE. Selanjutnya dibandingkan hasil perhitungan tebal perkerasan lentur, nilai repetisi izin terhadap kerusakan fatik (Nf) dan kerusakan retak alur (Nd) dari ketiga metode tersebut. Metode yang digunakan mekanistik-empiris. Data primer didapat dari Kementerian Pekerjaan Umum dan Perumahan Rakyat (PUPR) dan LHR0 dimulai pada tahun 2020, memperhitungkan pertumbuhan lalu lintas dari tahun 2020 sampai 2035, serta data sekunder asumsi dengan tetap mengacu pada peraturan dan penelitian sebelumnya. Hasil penelitian ini menunjukkan bahwa metode 2002 menghasilkan tebal perkerasan terbesar, sedangkan metode 2013 dan 2017 menghasilkan tebal perkerasan yang relatif sama. Namun metode 2002 menghasilkan repetisi izin terhadap kerusakan fatik (Nf) dan retak alur (Nd) terbesar. Sehingga disimpulkan metode 2017 menghasilkan desain lebih baik.
