Air Traffic Control is a key element of Air Traffic Management that ensures safe and efficient operations in airspace and airports. This paper presents a study on the development and implementation of Air Traffic Control logic in an airport airside simulation model. This research focuses on the identification and resolution of potential aircraft conflicts within the airport movement area and uses an agent-based modelling approach to address these challenges. The agent-based approach facilitates the modelling of complex interactions between different entities, allowing for a detailed investigation of airport traffic dynamics and potential improvements. The study includes the identifi-cation of conflict areas in airport infrastructure, the creation of a fictional airport movement area, and the development and integration of control logic to resolve conflicts during simulation runs of the designed simulation scenarios. The results of the sim-ulations provide valuable insights into the impact of traffic volume, the use of bidirectional taxiway segments, and bay operations on the total time spent by aircraft in the infrastructure, the average number of clearances issued for particular aircraft, or the number of clearances required to traverse the created infrastructure.

Wastewater treatment is a process to improve the water quality making it suitable for discharge back to the environment. Since wastewater majorly comes from humans, wastewater treatment plants are required in urban areas to improve the quality of the environment and life in cities. In Ecuador, wastewater treatment is frequently solved by a waste stabilization pond system which offer completely natural purifying processes. Unfortunately, most of the ponds are not in optimal conditions and show deficiencies in hydrodynamics and sediment removal. The objective of this work was to demonstrate how a hydraulic improvement of a maturation pond can be achieved by applying Computational Fluid Dynamics. Ansys Fluent software was used to perform a two-dimensional hydrodynamic simulation of the maturation pond in the Playas canton. Several interventions in the pond design were proposed and studied from the hydraulic efficiency point of view. It was generally concluded that the use of the Computational Fluid Dynamics is beneficial to design, analyze and optimize complex waste stabilization pond systems, resulting in an increased quality of life in cities.

Highway management implemented to a city ring road should be indisputably integrated into Smart City strategies. It is believed that the multi-agent approach should facilitate such an integration since it is able to cover heterogeneous entities. For this reason, an agent based environment for the simulation of different control strategies to highway management was required. The software tool Anylogic was selected for this issue, since it contains built-in traffic library and allows agent based modeling. In the previous work, the architecture and the framework model for the simulation environment were defined. This paper is focused on the highway model itself. It deals with the problems which had to be overcome when modeling a highway segment in Anylogic. It includes the infrastructure with ramps and exits, loop detectors for traffic flow mapping and gantries for transmission of control actions to the drivers. The generation and the setting of traffic flow, together with its mapping and the drivers' reaction on the control measures, are also covered. The highway model was validated with real data from Prague Ring Road and, within the mentioned framework model, it is now prepared for the simulation of different scenarios.

Congestions in peak hours is a phenomenon which is faced by many cities in the world. One of the goals of Smart City concept is to mitigate them and thus increase the level of driving comfort. The goal of this study was to determine the most significant parameters and understand which aspects are important for driving comfort. In the performed experiment, drivers with different socio-demographic characteristics and different driving experience observed the peak-hour and off-peak traffic How from drivers’ perspective and provided a subjective evaluation of driving comfort. The evaluation was then confronted to the observed traffic parameters which were either observed at place, or obtained from traffic detectors at the time when videos were recorded. It was found that immediate presence of heavy vehicles, light conditions or road geometry are parameters which can affect the level of comfort perceived by drivers just as instantaneous speed does. The findings from this study could improve the determination of traffic Level of Service and contribute to better understanding of this parameter by drivers.

Smart City phenomenon tends to be very strongly focused on citizens and their quality of life rather than measurable parameters of traffic, information and economics. In regard to traffic, very important parameter is Level of Service (LoS), quantification of which can be a troublesome task due to the number of observed parameters and qualitative nature of the phenomenon. Moreover, the subjective interpretation of LoS may differ for such user groups like police officers, traffic dispatchers and drivers which makes experts opinion less applicable. In the following study authors created an experiment aiming on the evaluation of recorded traffic situations by drivers (from drivers' perspective). The subjective qualitative assessment of respondents was compared to the quantitative data collected by traffic detectors installed in the places where recording took place. The results provide an innovative view on accepted and commonly used Level of Service evaluation methods and scales.

A city ring road with the parameters of a highway forms a part of the infrastructure of a modern city. The introduction of automated highway management to the city ring road moves it towards a smart city. This paper presents the framework model which was created with the aim of developing an agent-based control within the highway management in the future. The model was created in the multi-method simulation tool Anylogic since it allows the testing of both traditional rule-based algorithms and agent-based control. It is universal enough, thus, it can be used to compare different approaches to highway management. In this paper, a literature review focusing on the Multi-Agent Systems and their application in traffic and transportation is performed. Based on the above mentioned review, a system architecture for agent-based traffic control is proposed and the framework model is described.

This paper deals with the changeover from the decision tree (bivalent logic) approach to the fuzzy logic approach to highway traffic control, particularly to variable speed limit displays. The usage of existing knowledge from decision tree control is one of the most suitable methods for identification of the new fuzzy model. However, such method introduces several difficulties. These difficulties are described and possible measures are proposed. Several fuzzy logic algorithms were developed and tested by a microsimulation model. The results are presented and the finest algorithm is recommended for testing on the Prague City Ring Road in real conditions. This paper provides a guidance for researchers and practitioners dealing with similar problem formulation.
