Abstract

Industrial estates have a large scale workforce. Workers usually come from different locations, so they need transportation to get to the Industrial Estate location, because of the large movements of industrial workers. Especially at the turn of the morning and evening work shifts, at these hours the number of vehicle workers contributes to traffic congestion on the roads it passes. The survey was conducted at the entrance of the industrial area to determine the level of congestion that occurred at the entrance of the Industrial Zone road section, namely on the Kaligawe road, Jalan Candi Raya, Jalan Pantura Semarang - Kendal KM.12 especially when there was a shift of work shifts in terms of road capacity based on the Indonesian Road Capacity Manual. To determine the level of congestion if after provided worker transportation. From the data obtained, the largest VCR results in the Wijayakusuma Industrial Zone are 3.177 pcu / hour when the entry hours from the direction of Kendal are classified as the most jammed; in the Terboyo Industrial Zone is 0.917 pcu / hour when the hour enters from the direction of Demak; in the Temple Industrial Area is 0.875 pcu / hour when the hours go out towards Semarang are classified as quiet. After the workers of private vehicle users are transferred using buses, the largest VCRs are obtained from Type A buses with a capacity of 25 passengers, thus the value of VCRs in the Wijayakusuma Industrial Zone is 0.188 pcu / hour in the direction of Kendal; in the Terboyo Industrial Area is 0.066 pcu / hour in the direction of Demak; in the Temple Industrial Zone is 0.122 pcu / hour in the direction of Semarang. Planning to determine the number of buses that must be provided for each Industrial Estate, as well as efficient bus operating time.

Abstract

Tundaan dan Antrian kendaraan cukup panjang terjadi di Jalan Anjasmoro, Madukoro, Kokrosono karena volume dari ruas jalan yang tidak bertambah yang menyebabkan penyempitan jalan sehingga menyebabkan waktu untuk melintasi ruas jalan tersebut menjadi bertambah lama. Perhitungan tundaan dan panjang antrian berdasarkan data asli dari hasil survei yang dilakukan di Jalan Anjasmoro Raya, Madukoro Raya, Kokrosono. Sedangkan perhitungan konsumsi bahan bakar berdasarkan persamaan dari LAPI-ITB yang kemudian dikonversikan menjadi satuan mobil penumpang. Analisis hubungan antara tundaan dan panjang antrian terhadap konsumsi bahan bakar dilakukan dengan cara menganalisis regresi linier berganda. Berdasarkan analisis data dan pembahasan, hasil model regresi linier berganda dengan variabel bebas berupa tundaan (X1) dan panjang antrian (X2) terhadap variabel tidak bebas yaitu konsumsi bahan bakar (Y) adalah Y = 0.012 + 0.389 X1 + 0.0008547 X2 untuk pagi hari. Hasil analisis menunjukkan tundaan, panjang antrian tertinggi di perlintasan Madukoro Raya sebesar 273 m dikarekan memiliki jumlah tundaan yang lama dan konsumsi bbm tertinggi diperlintasan Kokrosono sebesar 300.32 liter dikarenakan memiliki tundaan yang lama, semakin tinggi nilai waktu tundaan dan panjang antrian semakin besar pula konsumsi bahan bakar yang terbuang. Berdasarkan ketentuan SK 770 tahun 2005 (LHR x frekuensi kereta api 35.000 smpk) pada perlintasan Anjasmoro Raya (2.580.614,4 smpk), Madukoro Raya (2.718.034,8 smpk), Kokrosono (1.173.984,3 smpk) sudah tidak memenuhi syarat sebagai perlintasan sebidang, sehingga sebaiknya sudah ditingkatkan menjadi perlintasan tidak sebidang seperti fly over, dll.pengaruh terhadap konsumsi bahan bakar, artinya semakin tinggi nilai waktu tundaan dan panjang antrian semakin besar pula konsumsi bahan bakar yang terbuang

Abstract

The increasing of transportation needs in big cities had almost a same problem, which is congestion on roads especially at the crossroads. Semarang is one of the cities located at a strategic point. Therefore, Area Traffic Control System came as a solution. Area Traffic Control System (ATCS) is a system that controlling road traffic intersections by using traffic lights where the setting of traffic light at each intersection was coordinated, so the road users could get a minimum delay. Government of Semarang plans to install  ATCS at the intersection of PRPP and Madukoro. The location of study is intersections of PRPP and Madukoro, where the intersection is a cross-city connecting route that is crossed by heavy and light vehicles and vehicles that going to and out from A. Yani airport. The method that used in this study is a survey method, including surveying traffic volume, queue length, delays, and light phase. The results then processed using a formula from the Indonesian Road Capacity Guidelines (PKJI'14). The results of this study is alternative coordination with a cycle time is 244 seconds for each intersection. Intersection I starts at 0 seconds, intersection II starts at 90 seconds. The degree of saturation obtained for the north and south PRPP intersections is 0. 28, for the east is 0. 36, for the west is 0. 42, while for intersection of north Madukoro  is 0. 35 , for the south is 0. 36, for the east is 0. 39, and for the west is 0. 45 So that the application of the Area Traffic Control System (ATCS) can have a positive resolution for reducing congestion and  get good traffic flow in the intersections of Madukoro and PRPP.

Abstract

The development of transportation occurs along with the development of residents in an area. The impact caused a buildup of vehicles on the highway. Transportation growth is linearly related to the Traffic Light Signaling Tool (APILL). Giving a Traffic Giver Tool is one way to regulate traffic. The methods that can be used for the duration of the APILL include the 1997 Indonesian Road Capacity Manual Method and Webster. The location of the study was in the Simpang Statue area of Pangeran Diponegoro and Abdulrahman Saleh. The webster method is calculated based on vehicles that come randomly. The calculation of the webster method is used to calculate the average delay of a vehicle when approaching an intersection where this delay occurs due to the large number of vehicles entering compared to the vehicle coming out of the intersection. the use of this webser method aims to be able to produce the optimum cycle time at each intersection. The Indonesian Road Capacity Manual Method (MKJI 1997) is a manual for road traffic calculations but cannot be used to analyze networks. This intersection obtains a degree of saturation average of ≥ 0.75, meaning that this intersection experiences a buildup of vehicles or congestion. The capacity and volume of vehicles in each intersection are inversely proportional. The intersection capacity can only accommodate around 2500 vehicles / hour but when on the field there are 7200 vehicles / hour. This makes APILL not work in each intersection. Simpang Statue of Pangeran Diponegoro and Abdulrahman Saleh is included in the F service (low speed blocked flow). The duration of the APILL time is not the same every day because the vehicle volume changes in each hour so that it is designed several plan APILL in the intersection. To overcome this kind of incident can be assisted by officers from the Police or the Semarang City Transportation Agency. Until now the APILL method still uses the Indonesian Road Capacity Manual 1997. Compared to the Webster method, the data needed is very minimal or incomplete. The results of the APILL time duration obtained using the 1997 Indonesia Jalan Capacity Manual method differ from the duration of time in the field and generally the results of calculations the duration of time obtained from this method added 10% of the calculation results and applied in the field.
