Opis:
One of the main problems within cities is the lack of convenient public transport connections, which offer passengers a comprehensive and efficient means of transportation from one place to another. Urban transport integration is intended to improve the functioning of public transport and, thus, is an activity that significantly contributes to the quality of transport services within cities. Transport integration may include solutions provided by urban public transport, as well as solutions based on the integration of public transport with individual transport modes. This article presents a comprehensive approach to the integration of urban transport. Exemplary tools integrating urban transport, along with examples of modelling in software for traffic microsimulation, are shown.

Opis:
It is essential to evaluate safety of marine traffic for the improvement of efficiency and safety of marine traffic. Spread of AIS makes observation of actual marine traffic more easily and faster than before. Besides, description of collision avoidance behaviours of ships are indispensable to simulate a realistic marine traffic. It is important to develop and implement an algorithm of collision avoidance corresponding to a target traffic or target area into the marine traffic simulation because actual actions for collision avoidance depend on circumstances where ships are sailing. The authors developed an automated marine traffic simulation system with AIS data. And in this paper, we proposed a series of systematic procedures for marine traffic simulation including analysing for collision avoidance behaviours using AIS data.

Opis:
Ship collision is a hazardous event within the chain of maritime transport. Collisions may result in human losses, adverse economic consequences, and environmental damages causing significant impact to local societies and related activities. A major factor in any risk analysis concerning ship collisions is the probability of these collisions occurring. The purpose of this study is to assess the probability of ship-to-ship collision in the Aegean Sea. The basic concept of the developed model is to (statistically) simulate traffic flow in the area of interest and determine the collision candidates; this will be implemented in a pilot study in a segment of the Aegean Sea. The input of this effort is based on values that are extracted from statistical analysis of the international fleet in combination with the study of maps depicting traffic flow in the studied area. Hence, it does not employ detailed AIS data. The obtained results are presented and their agreement with actual incidents is discussed in depth. The paper concludes with interesting insights of the aforementioned tasks.

Opis:
Railway traffic simulation, taking into account operation and maintenance conditions, is not a new issue in the literature. External effects in such networks (e.g. level crossings) were not taken into account in studies. The used models do not take into account sufficiently the process of degradation and recovery of the network. From the technical side, currently carried out simulations are made using similar approaches and techniques as in the initial stage of research. Well-established work in this area could be the basis for evaluation of new solutions. However, the progress in simulation tools during the last years, especially in performance and programming architecture, attempts to create a modern simulation tool. In the paper were presented the main assumptions for the evaluated event-based simulation method, with application to stiff-track transportation networks.

Opis:
The probability of an accident in transportation systems can serve as a measure of these systems safety or risk, depending on the objective. Therefore numerous methods and models for risk evaluation, with respect to maritime, have been developed. However, these models are either too simplified, allowing relatively fast analysis but very often missing the substantial links among the model variables, or they are too slow for effective analysis, due to computational complexity, not necessarily being backed-up with the complexity of the model itself. Thereby, this paper introduces a novel method evaluating the probability of ship-ship collision in the maritime transportation system focusing on the open sea collisions, applying the queuing theory in the simulation model. The model allows relatively fast prediction as it focuses on the specific events (e.g. accidents), instead of simulating the whole traffic. To support this hypothesis a case study is presented focusing on a selected element of transportation system in operation.

W niniejszym artykule przedstawiono wieloelementowe, sprzętowo-programowe środowisko symulacyjne do sterowania ruchu drogowego. Główną ideą było wytworzenie łatwo rozbudowywalnego, elastycznego symulatora ruchu drogowego umożliwiającego prowadzenie badań z zakresu sterowania ruchem drogowym. Wykorzystano do tego specjalnie opracowane makiety obszarowe (różne rodzaje skrzyżowań dróg), sterowniki PLC oraz opracowano program komputerowy interpretujący dane pochodzące z makiet.
The multi-component, hardware and software simulation environment for traffic control is presented in this paper. The main idea was to create easy extendable, flexible simulation facility for research in the field of traffic control. A specially designed model area (different types of road junctions: a T-type intersection, crossing four roads classical and a typical junction, which is a model of a real system of roads in Szczecin), PLCs and a proprietary computer program that interprets data from the model were used for this purpose. The paper presents the concept of a hardware-software simulator (Fig. 1) together with a description of individual elements (Figs. 2, 3 and 5). It is worth mentioning that the way to develop a program and the layout and type of PLC allows the connection of any mock-ups that will provide the appropriate signals. These signals are interpreted and on the basis of them the so-called scenario will be generated. Finally, the paper presents a real situation that could occur at the T-type intersection (vehicle enters the intersection and cannot leave it). Due to the fact that the models are equipped with the so-called inductive loops, the system offers an appropriate scenario to avoid blocking the intersection. The paper can be concluded with a statement that the developed hardware-software simulator allows conducting research in the field of traffic control in a safe and collision-free way.

Opis:
Vehicle emission calculation is critical for evaluating motor vehicle related environmental protection policies. Currently, many studies calculate vehicle emissions from integrating the microscopic traffic simulation model and the vehicle emission model. However, conventionally vehicle emission models are presented as a stand-alone software, requiring a laborious processing of the simulated second-by-second vehicle activity data. This is inefficient, in particular, when multiple runs of vehicle emission calculations are needed. Therefore, an integrated vehicle emission computation system is proposed around a microscopic traffic simulation model. In doing so, the relational database technique is used to store the simulated traffic activity data, and these data are used in emission computation through a built-in emission computation module developed based on the IVE model. In order to ensure the validity of the simulated vehicle activity data, the simulation model is calibrated using the genetic algorithm. The proposed system was implemented for a central urban region of Nanjing city. Hourly vehicle emissions of three types of vehicles were computed using the proposed system for the afternoon peak period, and the results were compared with those computed directly from the IVE software with a trivial difference in the results from the proposed system and the IVE software, indicating the validity of the proposed system. In addition, it was found for the study region that passenger cars are critical for controlling CO, buses are critical for controlling CO and VOC, and trucks are critical for controlling NOx and CO2. Future work is to test the proposed system in more traffic management and control strategies, and more vehicle emission models are to be incorporated in the system.

Opis:
The method for the choice of rational regimes of traffic light control is developed based on the minimization of the number of violations the requirements of traffic light signals by pedestrians depending on the volume-capacity ratio of traffic lanes and control of vehicular queue on the approach to the stop-line. Assessment of rationality is carried out considering the simultaneous impact of such factors as roadway volume-capacity ratio, traffic light restrictive signal duration, the number of violations of the traffic rules by pedestrians, and maximal queue length of vehicles. The model of the change of the number of violations of the rules of crossing the roadway by pedestrians depending on the volume-capacity ratio of different intersection types is developed in this paper. The model of determining the maximal vehicular queue length before intersections depending on the volume-capacity ratio and the share of the restrictive signal on the lane in the control cycle is developed. Recommendations about the choice of rational regimes of traffic light control depending on traffic delay, planning parameters of the road network, and pedestrian behavior are proposed.

In the paper a standard, model and tool based solution for the testing of distributed cooperative transport systems is introduced. Based on the TTCN3 semantic, a specific model based approach for dealing with the complexity of the necessary distributed test systems was developed. With the help of some practiceoriented examples from the traffic sector this approach is presented.

Opis:
This paper evaluates near ship-ship collision situations in the Tagus River Estuary using a simulation model of ship navigation in restricted waters. The simulation model consists of a ship collision avoidance model based on the Artificial Potential Field (APF) method, which has been improved to account for the lateral distribution of traffic along the route, the ship type and length and speed development of the ships along the trajectory. AIS data of ships entering and leaving the port of Lisbon are analysed to obtain the main characteristics of traffic parameters used as input for the traffic simulation model, such as: the routes of the vessels, speed distribution along the routes, traffic density and characteristics of the ships in each route, among others. First, the improved model of ship navigation and the Monte Carlo simulation technique are used to simulate the marine traffic in the Tagus River Estuary. Then, the concept of “ship domain” is used as collision criterion to determine the number of near collisions and the locations where they are most likely to occur. Finally, the simulation results are compared to the ones obtained from raw AIS data to assess the capability of the simulation model for marine traffic risk analysis.

Moreover, the main survey results are presented as they relate to the Romanian road and rail border-crossing points (BCPs) with the Eastern neighbourly country, Moldavia. Results include the actual status of the road BCP, surveys on exiting and entering traffic flows, answers to specific questionnaires of the truck and car drivers in relation with origin-destination of the trips, average waiting time in queue and time required for procedures and controls. Discussion on the mathematical modelling is presented and a provisional simulation model is developed, using ARENA software. The early results are used in order to introduce the need for future assessment of the transit time in a road BCP, with the main purpose: the substantiation of the strategic and operational actions for improvements in trade and transport crossings of the EU borders, considering the need for more vigilant and less time-consuming checks at the outside borders of the EU.
Ce papier donne un aperçu sur le projet ACROSSEE (financé par le FEDER dans le cadre du programme SEE), ses objectifs, la méthodologie générale, et les principaux résultats; en outre,les principaux résultats de l'enquête sont présentés en rapport avec les points routiers et ferroviaires de passage frontaliers (PPF) entre Roumanie et Moldavie. Les résultats comprennent l'état actuel du PPF de la route; enquêtes sur la sortie et l'entrée des flux de trafic; réponses aux questionnaires spécifique des chauffeurs de camions et de voitures en relation avec l'origine-destination desvoyages; le temps moyen d'attente et le temps nécessaire pour accomplir les procedures du contrôle. Discussion sur la modélisation mathématique est présentée et un modèle de simulation prévisionnel est développé, en utilisant le logiciel ARENA. Les premiers résultats sont utilisés afin d'introduire la nécessité d'une évaluation ultérieure du temps de transit par un PPF routier, ayant comme objectif principal la justification des actions stratégiques et opérationnelles pour des améliorations dans le commerce et le transport franchissant les frontières de l'UE, compte tenu de la nécessité d'un contrôle plus vigilant et habituellement long à la frontière extérieure de l'UE.

Opis:
In the field of railway transport many activities are taken to achieve higher availability of offered services. A few of them consider more flexible rules of creating and starting trains. This requirement translates into greater complexity of railway traffic opertional management and control (RTMC). At the Faculty of Transport of Warsaw University of Technology classes for students have been conducted for several years with the use of the KSR-EDU stand. Taking into account the described trends of railway traffic nature, the KSR-EDU stand was connected to a simulator of real railway traffic. This connection allows to practice various and more complicated movement scenarios. The article describes RTMC layer model and simulator architecture in general. Two simulation tasks are described in details. The algorithms of simulation tasks for different levels of simulation are presented. In the end the benefits arising from application of the simulation for particular didactic tasks are discussed.

Opis:
W artykule opisano badania prędkości i struktury kierunkowej pojazdów na ulicy Architektów w Rzeszowie. Ulicę zaprojektowano dla obsługi ruchu lokalnego, natomiast jest także wykorzystywana dla ruchu tranzytowego. Celem badań było określenie rozkładu prędkości pojazdów oraz określenie udziału pojazdów tranzytowych w całkowitym ruchu drogowym na ulicy. Wyniki badania posłużyły do opracowania koncepcji uspokojenia ruchu ze względu na zwiększone zagrożenie bezpieczeństwa ruchu drogowego. Wyniki badań i wnioski z analizy świadczą o konieczności wykonywania prognoz ruchu zaawansowanymi metodami w celu odpowiedniego zaprojektowania ciągów komunikacyjnych eliminujących ruch tranzytowy z ulic osiedlowych niedostosowanych do takiego ruchu.
The article describes the speed distribution and directional structure of vehicles on the Architektów street in Rzeszow. The street has been designed for local traffic, but it is also used for transit traffic. The results of the study have been used to develop the concept of traffic calming zone due to increase the road safety. The results and conclusions of the analysis demonstrate the necessity to make advanced traffic forecasts for the appropriate design of road network what eliminates transit traffic from unoccupied street traffic.

Opis:
Several abnormal driving behaviors in violation of traffic rules can be observed on the road network in Kuwait. These behaviors would likely hinder traffic flow and can worsen traffic congestion. These behaviors may also cause simulation model outputs to deviate from actual traffic conditions. Such aberrant behaviors have not been addressed in the literature, either in terms of the rate of occurrence or in terms of the factors influencing drivers’ engagement in these behaviors. This study sheds light on drivers' tendencies to engage in five maneuvers that fall into the category of behaviors that violate traffic rules and could have detrimental effects on traffic conditions in Kuwait. The tendencies of drivers to engage in such behaviors were elicited through self- report questionnaires. The study found that a significant number of drivers in Kuwait display these driving behaviors. The effects of driver gender, driver age, and annual driving distance on the tendency of drivers to engage in such behaviors were investigated.

Opis:
“Safe voyage from berth to berth”: This is the goal of all e-Navigation strains driven by new technologies, new infrastructures, and new organizational structures on bridge, on shore, as well as in the cloud. To facilitate these efforts suitable engineering and safety/risk assessment methods are required. Understanding maritime transportation as a sociotechnical system allows the usage of system-engineering methods. Simulation-based test beds for verification and validation (V +V) of e-Navigation technologies are important methods to obtain functional safety and reliability. The modeling and simulation toolset HAGGIS is a cosimulation system for the evaluation of e-Navigation concepts and systems. It provides a maritime traffic simulator and a physical world (n-body) simulator and services for finding rare events of failures. HAGGIS is accompanied by the physical test bed LABSKAUS, which implements a reference port and waterways. This paper describes an integrated and seamless approach for developing new e-Navigation technologies starting with virtual simulation-based safety assessment and ending in physical real-world demonstrations. It gives an overview of the actual test bed and introduces requirements, concepts and elements of HAGGIS and LABSKAUS, which are joined in the e-Maritime Integrated Reference Platform (eMIR) test bed.

Opis:
As part of this research, a computer model of the existing bidirectional single-track railway line section between Zagreb Glavni and Turopolje railway stations has been developed, and it has been modified with the aim of developing a new model of the double-track line on this line section, and which in relation to the existing conditions also includes additionally the new stop Donja Lomnica. The purpose of developing the new model of the double-track line is to study the possibility of introducing a new plan of cyclic timetable of the suburban and regional trains that would significantly improve the quality of existing service in railway suburban traffic of the city of Zagreb. The procedure of single-track line model modification has been performed based on simulation of railway operations in the station areas with the aim of improvement of line capacity necessary for introduction of new solution of the cyclic timetable. Within this approach, the solutions for modification of railway infrastructure in stations have been selected which have proven to be the best regarding the achievement of the mentioned purpose. As part of this work, a new solution of cyclic timetable of suburban and regional trains on the new model of the double-track railway line has been proposed by taking into consideration the existing characteristics of traffic of other trains on the observed railway line section, as in Zagreb Glavni railway station which represents the main node in the network. Stability of this cyclic timetable has been tested by the application of three different simulation scenarios. The results of this research have proven that the introduction of the new model of double-track line can enable stable application of the proposed cyclic timetable.

Opis:
The problem of effective management of the railway freight flows in the conditions of the multiplicity of operators requires the rationalization of the transportation process. The further development of the authors’ research on creating the mathematical model of the railway freight flows in the region transportation and technological system is presented. For the first time, the theory of algebraic curves of higher orders is used to create a territorial model of the oligopolistic market of freight traffic. The algorithm for creating a model of freight transportation is based on the analysis of the qualitative and quantitative indicators of the operator company in the considered region with the use of analytical, heuristic, and graphic capabilities of math software. The theoretical substantia-tion of the territorial picture, the freight transportation market in the region is obtained. The carried-out research allows to specify possible ways of optimization of freight traffic distribution.
