“…The quantitative risk assessment of runway veer-off has been carried out with a methodology inspired by the one developed by the Italian Civil Aviation Authority (ENAC) with University of Rome La Sapienza, based on assessing the risk deriving from aeronautical activities in surrounding areas of airports [23][24][25]. This methodology involves the creation of a structured set of methods and models to represent the risk through the product of the probability of occurrence with the damage severity.…”

Runway excursions are the main risk for runway safety: operational protection areas mitigate the effects of events classified as veer-off, overrun, and undershoot. This paper presents a methodology for the quantitative risk assessment of runway veer-off in an international airport whose name will not be revealed for privacy reasons. The proposed methodology is based on similar principles adopted in other aviation risk analyses. The Real Level of Safety (RLS) related to the veer-off accident was calculated through the implementation of a retrospective analysis that permits to define a frequency model, a location model and a consequence model. Instead, Target Level of Safety (TLS) was defined through the risk matrix and acceptability criteria present in the International Civil Aviation Organization (ICAO) Safety Management Manual. Finally, the risk of veer-off accidents in the airport under evaluation was determined by using primary data provided by the airport management body. Risk values were calculated in more than 1300 points around the runway and they were used to assess the current level of safety. The authors present a risk map that allows identifying the areas in the strip with the highest risk of a veer-off accident. The obtained results demonstrate that the developed methodology represents a useful tool to define TLS and to assess whether infrastructural and operational modification need to obtain the required level of safety.

“…Element/defect i is along more than two-thirds of section length Given the above procedures, it is possible to simulate values of BIR s and define appropriate classes of risk. To this end, the authors considered six probabilistic classes of risk level, as usually done for transport infrastructure risk assessment [47][48][49][50][51][52][53]. The definition of ranges for each class requires a significant number of monitored branches.…”

Attention to the most vulnerable road users has grown rapidly over recent decades. The experience gained reveals an important number of fatalities due to accidents in urban branch roads. In this study, an analytical methodology for the calculation of urban branch road safety is proposed. The proposal relies on data collected during road safety inspections; therefore, it can be implemented even when historical data about traffic volume or accidents are not available. It permits us to identify geometric, physical, functional, and transport-related defects, and elements which are causal factors of road accidents, in order to assess the risk of death or serious injuries for users. Traffic volume, average speed, and expected consequences on vulnerable road users in case of an accident allow us to calculate both the level of danger of each homogeneous section which composes the road, and the hazard index of the overall branch. A case study is presented to implement the proposed methodology. The strategy proposed by the authors could have a significant impact on the risk management of urban roads, and could be used in decision-making processes to design safer roads and improve the safety of existing roads.

“…Moreover, different capacities can be determined as regards the weather conditions: optimal capacity (i.e., number of movements that can be managed in 1 h in optimal qualified conditions when a visual flight is possible) and reduced capacity (i.e., obtained for adverse weather conditions, especially for low visibility conditions, when the flight should be instrumental) [8]. Other factors affect the overall airport capacity [9]: the geometrical layout of the runway and taxiway systems, geometrical and logistic setup of the apron areas, the size and speed of expected aircraft, the approach and departure procedures [10], the procedures adopted by ATCO [11], the traffic routes and the air traffic management technologies, and the safety [12][13][14] and environmental procedures adopted to manage the traffic.…”

At the international level, the interest in airport capacity is growing in the last years because its maximization ensures the best performances of the infrastructure. However, infrastructure, procedure, human factor constraints should be considered to ensure a safe and regular flow to the flights. This paper analyzed the airport capacity of an airport with two crossing runways. The fast time simulation allowed modeling the baseline scenario (current traffic volume and composition) and six operative scenarios; for each scenario, the traffic was increased until double the current volume. The obtained results in terms of average delay and throughput were analyzed to identify the best performing and operative layout and the most suitable to manage increasing hourly movements within the threshold delay of 10 min. The obtained results refer to the specific examined layout, and all input data were provided by the airport management body: the results are reliable, and the pursued approach could be implemented to different airports.
