DETERMINATION OF A DETECTION FIELD STATE ON THE BASIS OF DIGITAL IMAGE GRADIENTS

Summary: The paper presents an original method of determination of detection field state with the use of image data. The presented method utilizes a video stream obtained from the camera placed above a road. The input image sequence consists of consecutive frames taken from the video stream. Each image from the input image sequence is converted into point image representation. For each image from the input image sequence, the sum of edge paints is calculated within the detections field. The state of the detection field is determined on the basis of calculated sums of the edge points. Vehicles driving through the detection field change its state. Analysis of the state of the detection field enables vehicle detection. Selected experimental results are provided.Keywords: detection field, point image representation, vehicle detection

POSSIBILITY OF IMPLEMENTING THE METHOD FOR TRAFFIC SMOOTHNESS ESTIMATION FOR OPERATIONAL AIR TRAFFIC FLOW MANAGEMENT

Summary: One of the primary measures to ensure the safety and economy of air traffic is the traffic flow management. FMP service was established for this purpose. It imposes regulations on the traffic if it exceeds the volume treated as a limit. The aim of this study is to check whether it is possible to use for this purpose the concept of the traffic smoothness instead of the traffic volume. The measurements and analysis of air traffic controllers occupancy during handling real traffic were carried out. At the same time we have recorded the actual traffic volume and traffic smoothness. As a result, we have found a relationship between the traffic smoothness and controller’s occupancy, as well as some inconvenience during operational use of the traffic volume in FMP’s activity. As a result, this leads to the conclusion about the possibility of using the modified method of estimating the smoothness to operational air traffic flow management.Keywords: air traffic smoothness, controller occupancy, air traffic management

ASSESSMENT OF THE SELECTED ALGORITHMFOR LANDING AIRCRAFT SCHEDULING

Summary: Managing air traffic in terminal areas is one of the biggest challenges for air traffic management services. The reason for that is a high number of aircraft performing complex maneuvers in limited airspace. The process of landing aircraft scheduling is sometimes supported with computer systems that implement algorithms, which aim is to achieve the aircraft traffic flow with the best performance. The aim of this paper is to assess the reliability of selected scheduling algorithm with the use of the method based on the air traffic flow model in the form of a colored Petri net. Cellular automata-based scheduling algorithm found in the literature has been selected for an assessment. Comparing the results to the practice of Warsaw TMA, where no controller support system within the scope of landing aircraft scheduling was implemented, one can notice a beneficial impact of the application of the scheduling algorithm. Application of the examined algorithm would allow for both increasing capacity and reliability of timely execution of planned operations. This indi-cates the existence of high potential for implementation of systems supporting the controller in landing air-craft scheduling process.Keywords: air traffic, airport capacity, scheduling quality

FUZZY REASONING FOR EVALUATION OF SATELLITE SIGNAL QUALITY

Summary: The results of the carried researches indicate that satellite signal to be in good quality must have impeccable external conditions. Whatever deterioration they have - an increase in cloud cover, the occurrence of rainfall, high humidity or increase in solar activity - it cause rapid weakening of the satellite signal quali-ty. Based on the results, it can be concluded that the satellite signal is very sensitive phenomenon to analyze and work on the development of satellite systems to eliminate this drawback must still be done.Keywords: satellite signal, fuzzy inference, tropospheric error

EXTENSIBLE LANGUAGE FOR DATA DESCRIPTION IN DIAGNOSTIC OF TRAFFIC

CONTROL SYSTEMS


Abstract: Modern railway traffic control systems commonly use Information Technology (IT) in order to perform processing and logging diagnostics data in diagnostic centres. The lack of standards for diagnostic data structures and the lack of common mechanisms of acquiring data causes, that the producers of systems use their own solutions in this domain. Thus, in spite of using modern technologies, there is a great difficulty in obtaining consistent diagnostic data and makes its further analysis difficult. In the article the using of the specialised XML-based markup language was proposed. This language can be used to unify structures of diagnostic data obtained from the different railway traffic control systems. The unification of diagnostic data structures would allow not only for building interfaces between railway traffic control systems and diagnostic centres, but also for developing the unified diagnostic system.Keywords: railway traffic control systems, diagnostics, XML

DEFINITION OF DATA EXCHANGE STANDARD FOR RAILWAY APPLICATIONS


Abstract: Railway similar to the other branches of economy commonly uses information technologies in its business. This includes, inter alia, issues such as railway traffic management, rolling stock management, stacking timetables, information for passengers, booking and selling tickets. Variety aspects of railway operations as well as a large number of companies operating in the railway market causes that currently we use a lot of independent systems that often should work together. The lack of standards for data structures and protocols causes the need to design and maintain multiple interfaces. This approach is inefficient, time consuming and expensive. Therefore, the initiative to develop an open standard for the exchange of data for railway application was established. This new standard was named railML. The railML is based on Extensible Markup Language (XML) and uses XML Schema to define a new data exchange format and structures for data interoperability of railway applications. In this paper the current state of railML specification and the trend of development were discussed.Keywords: railway traffic control systems, railML, XML

THE ANALYSIS OF POSSIBILITY OF APPLYING THE HCM 2010 METHODFOR CALCULATIONS CAPACITY OF LANES ON ROUNDABOUTS ENTRY

IN POLISH CONDITIONS

Summary: The main aim of this article was to verify whether it is possible to use the models included in the HCM 2010 method for estimating the roundabouts entry lane capacity in Poland. The models presented in HCM 2010 method were compared with empirical values of roundabouts entry lane capacity of one-lane roundabouts and two-lane roundabouts and also with own models that allow for determination of roundabouts entry lane capacity. The comparisons made possible to determine overall differences in forms of comparable models. In the HCM 2010 method the critical headway and the follow-up headway are the two key parameters of model used for determinig the roundabouts entry lane capacity. These parameters are usually strongly correlated with behavior of drivers and their local habits. Hence, the attempt to adopting the HCM 2010 models to Polish conditions consist of checking whether the use of values of psychotechnial parameteres for roundabouts localized in Poland will improve the quality of fit to the HCM 2010 models bothfor empirical data and for own models.Keywords: one-lane roundabouts, two-lane roundabouts, roundabouts entry capacity

EXPLOITATION OF SYSTEM SWITCH POINT MECHANISM – SWITCH POINT.FORCE DEFINITION IN THE SYSTEM

Summary: The switch motor is a very important component among railway traffic control devices. It has an immediate influence on the safety of passengers and goods being transported. Its cooperation with the railway switch is the most important element of the traffic control process. Also, diagnostics of the railway switch and its cooperation with the railway switch is a very important process. Unfortunately, the diagnostic process and analyses of the condition of the switch motor and the railway switch system do not meet the standards they should meet. It might seem that the development of technology should cause an improvement in the diagnostic process and the analysis of the condition of the devices. Unfortunately, this is not the case. First of all, there are no precise definitions of forces occurring in the switch motor and the railway switch system. Secondly, there are no clear guidelines concerning the interpretation of measurement results.Keywords: switch point mechanism, point switch, measurements

TRAFFIC FLOW PREDICTION IN ADJACENT JUNCTIONS USING NEURAL NETWORK

Summary: The paper presents a proposal of using one neural network for short time prediction of traffic flow on two adjacent junctions of a traffic route. The traffic flow on the second junction is predicted on the basis of historic data registered at the first junction. This allows to forecast the flow on the second junction in the case of failure of its flow measuring devices. The elaborated design is validated using a data set of traffic flow measurements comprising nearly 20 thousand measurements collected in a period of over six months. Results prove that the design may be incorporated as a component of a prediction module in Intelligent Transport Systems.Keywords: traffic flow forecast, neural networks, time series

ROAD TRAFFIC DATA COLLECTION USING UAV

Summary: UAVs record compressed video streams. The capability for using such streams for extraction of trajectories of moving vehicles, using image processing is investigated. A tracking algorithm based on sub-tracting a background model from the current content of frames and estimating objects positions using Kal-man filter is used. A sequence of compressed video segments is processed to obtain object trajectories. The trajectories are statistically analysed. The range of compression values is determined for which the parame-ters of the trajectories are close. Lossy compression in the range 500-20000, using the standard H.265, is suitable for recording video by UAVs and does not significantly change the results of tracking vehicles.Keywords: UAV, road traffic parameters, lossy compression

ASSESSMENT OF CONFORMITY OF TRAFFIC VOLUMES ON SECTIONS IN URBAN ROAD NETWORK IN TERMS OF THE SIMPLIFICATION OF ITS STRUCTURE

Summary: An accurate representation of all components of urban road network is a time-consuming and costly task. For the purposes of travel modelling such detail is not always justified. Therefore, there is a need for construction of a simplified road network models. In such models traffic flows measured at the beginning and at the end of the section may be different. Simplifying the structure of the road network model oneshould aim to ensure that the dispersion of these values was as small as possible. This paper proposes somemeasures of conformity assessment of traffic volumes measured at the beginning and at the end of the section based on the coefficient of variation. The analysis was conducted for simplified road network model of Bielsko-Biala.Keywords: road network structure, traffic volume, travel modelling
