Dalam satu fase penerbangan dari bandar udara asal menuju bandar udara tujuan, pesawat udara akan mengalami beberapa fase terbang, salah satunya adalah fase taxi-out. Fase ini memberikan kontribusi yang cukup signifikan terhadap konsumsi bahan bakar pesawat udara, terutama ketika terjadi kepadatan lalu lintas pesawat udara karena waktu yang dibutuhkan pesawat udara untuk taxi-out menjadi lebih lama dari yang seharusnya. Penelitian ini bertujuan untuk menganalisis pengaruh kepadatan lalu lintas pesawat udara terhadap waktu taxi-out dan konsumsi bahan bakar di Bandar Udara Soekarno Hatta-Jakarta. Hasil perhitungan menunjukkan rata-rata 30% dari total jumlah penerbangan pada bulan Juli, Agustus dan September tahun 2014 mengalami keterlambatan keberangkatan karena terjadinya kepadatan lalu lintas pesawat udara pada saat taxi-out. Hal ini mengakibatkan kelebihan konsumsi bahan bakar pesawat udara sebesar 29% dibandingkan apabila pesawat udara dapat melakukan taxi-out dalam keadaan tanpa hambatan. [The Effect of Air Traffic Congestion on Taxi-out Time and Aircraft Fuel Consumption (Case Study: Soekarno-Hatta International Airport)] In a single flight, from the origin airport to the destination airport, the aircraft experiences several different flight phases, one of which is taxi-out phase. This taxi-out phase contributes significantly to aircraft fuel consumption particularly when air traffic congestion occurred due to the time needed in taxiing become much more longer than it should be. The aim of this research is to analyze the effect of air traffic congestion on taxi-out time and aircraft fuel consumption at Soekarno-Hatta International Airport. The results show that the average of 30% of the total number of flight in July, August, and September 2014 has been delayed due to air traffic congestion on taxi-out phase and it caused an increase of 29% on aircraft fuel consumption compared to uncongested taxi-out.

The paper deals with the Zagreb Terminal Airspace capacity. The basic scenario has been modelled using the RAMSPlus simulator and capacity has been calculated by using the WMSE method which takes into account the peak-hour workload based on air traffic controllers’ tasks. The problem of traffic congestion has been analyzed and several case study scenarios have been simulated. The conducted simulations have demonstrated that in the conditions of increased traffic loads (traffic demand amounting to 6% annually) the working technology and the airspace organization of Zagreb Terminal Airspace will become a restricting factor at peak-hour workloads. The new technologies in Zagreb Terminal Airspace (P-RNAV routes and airspace sectorization) will enable the reduction in air-traffic controller’s workload regarding radar vectoring, radio-telephony and coordination tasks. This should increase the airspace capacity and thus enhance the safety and orderly flow of air traffic. KEY WORDS: terminal airspace, capacity, simulation, workload, task, sectorization

Traffic demand is an important factor in planning the airport capacity and facility. Forecasting future traffic demand becomes a necessity in determining the amount of capacity or dimension of airport facilities. There are factors that have to be considered in predicting the traffic demand. This study aimed to examine the relationship between the demand for air traffic and the airport capacity, and discuss the relationship between the variables that affect traffic demand and the variables that affect the increase in the capacity of the airport. This study uses probabilistic causality approach. The results of case study in Soekarno-Hatta International Airport show that, in general, the increase in the probability of the traffic demand variables can affect the increase in the probability of airport capacity variables. The probability value of the airport capacity variables which significantly increased are runway, apron and curbside. Keywords: Demand, airport capasity, causality, probabilistic network. Permintaan trafik merupakan faktor penting dalam merencanakan kebutuhan kapasitas dan fasilitas di bandara. Peramalan permintaan trafik di masa yang akan datang menjadi suatu kebutuhan dalam menentukan besaran atau dimensi fasilitas bandara. Banyak faktor yang perlu dipertimbangkan dalam memprediksi permintaan trafik. Penelitian ini bertujuan untuk mengkaji hubungan antara permintaan trafik angkutan udara dengan kapasitas bandara, dan membahas hubungan antara variabel-variabel yang mempengaruhi permintaan trafik dan variabel-variabel yang mempengaruhi peningkatan kapasitas bandara. Penelitian ini menggunakan pendekatan kausalitas probabilistik. Hasil analisis pada studi kasus Bandara Soekarno-Hatta, diperoleh bahwa secara umum peningkatan probabilitas pada variabel permintaan trafik dapat mempengaruhi peningkatan probabilitas pada variabel kapasitas bandara. Nilai probabilitas variabel kapasitas yang meningkat secara signifikan adalah landas pacu, apron dan curbside. Kata kunci: Permintaan, kapasitas bandara, kausalitas, jaringan probabilistik.

Employees and employers are facing issues in work life balance. It has become a difficult domain now, because the work needs have increased due to an increase in work pressure and complexities in handling the technology. As there are drastic changes in the rules and regulations in the work scenario of the aviation industry, it makes work life balance of employees difficult and set more hurdles. Hence there are many distractions and imbalances in the life of women employees in the aviation industry working across all levels. This work pressure is creating high level of hurdles in maintaining a harmonious job and family life, especially for female aviation employees. Data is collected from 50 female crew members working at Cochin International Airport. The objective of this study is to analyze the work life balance of working females of Cochin International Airport and its influence on their personal and specialized lives. The result of the study shows that the management should frame certain policies which will help employees to have the balance among their personal and expert lives.

The European Union policy strategies on the sustainability of the transport system pursue the goals of maximizing safety and environmental benefits and reducing the severity and frequency of crashes, congestion, and pollutant emission rates. A common issue is the planning of the most effective solution for operational and safety management at intersections. In this study, an egg turbo roundabout is proposed as the alternative solution to a conventional roundabout in Southern Italy which suffers from traffic congestion. A comparative analysis is carried out using microsimulation techniques to investigate the safety effects and operational improvements of converting a traditional priority intersection into standard roundabout or turbo roundabout layout. In particular, the VISSIM software is used to explore the most relevant operational performance measures: queue length, travel times and delays. The lowest values of these measurements are recorded for the simulated turbo roundabout, thus making this scheme more appropriate in terms of operational performances. With regard to safety analysis, the Surrogate Safety Assessment Model (SSAM) is used to collect information on the predicted number of conflicts, the probability, and severity of the potential collisions. The results suggest that, for the specific case study, the safety levels of the standard roundabout and the turbo roundabout are approximately comparable.

Riyadh, the capital of Saudi Arabia, suffers from traffic congestion like other modern societies, during peak hours but also all day long, even without any incidents. To solve this horrible traffic congestion problem, various efforts have been made from the Active Traffic Management (ATM) aspect. Ramp metering (RM) is one of the representative methods of the ATM and has already proven its value in many locations worldwide. Unfortunately, RM has not yet been fully implemented in Saudi Arabia. This research aimed to assess the applicability of RM to a freeway in Riyadh using microsimulation. The widely known software VISSIM (PTV Planung Transport Verkehr AG, Germany, 1992) was chosen to compare the performances of various RM operating scenarios, such as fixedtime operation with different sub-scenarios and traffic-responsive operation using ALINEA (Asservissement Lineaire d’entree Autoroutiere) algorithm. For the simulations, this study targeted Makkah Road, one of the major freeways in Riyadh, and collected geometrical data and traffic data from that freeway. Analysis of four main scenarios and eight sub-scenarios, proved that overall performance of the fixed-time RM operation is generally good. The sub-scenario 4V3R of the fixed-time RM operation was the best in average queue length reduction. However, the traffic-responsive operation was best in average speed improvement.
