Opis:
The testing of cooperative transport systems is challenging because of their complexity and distributions. With TTCN3 a standard based procedure is available for specifying, executing and evaluating the testing of distributed systems such as cooperative transport systems. 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:
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:
The dynamics of development of transport systems in cities makes it harder to control the proper traffic management. It happens that decisions on the reorganization of the traffic and utilization of automated control are made on the basis of insufficient principles. Due to that, the costs of the technical implementations are spent without a simultaneous traffic improvement. For this reason, it is necessary to use tools allowing an efficient analysis of the current and future situation of the road. Utilization of a computer simulation seems to be most effective. The paper is focused on an example of computer simulation analyses of the two integrated cross roads in Szczecin. Based on the simulation model, the assessments of the planned implementation solutions were realized. It includes the analysis of the appropriateness of traffic lights utilization for the analyzed road sections.

Opis:
Currently used, computer railway traffic control systems , communicate via standard digital interfaces: CAN, Ethernet or RS485. In order to carry out the proof of security, it is necessary to test the functioning of the interfaces under different conditions. The IBIS model (I/O Buffer Information Specification) was used to simulate the transmission of signals through interfaces. The article discusses the applied interface models and simulation results in various conditions. The presented results can be used to prove the safety of transmission in computer railway traffic control systems.

Opis:
Paper presents an experiment using a specialized tool - traffic simulator. The results of computer analysis of traffic have been presented as a very quick, easy and cheap method as base of making complex decisions in the process of organizing traffic. For example, motion simulation for the planned reduction in traffic, resolved the dilemma at the local level, the theoretical analysis at this level is difficult for obvious reasons.

Opis:
In this paper we present the results of global optimization of green wave parameters (offsets, opening times, speed limit) for the main artery in the city of Wrocław (Poland). The optimization process was performed in ArsNumerica Execution Environment [1] and involved two different objective functions: the average waiting time and the average queue length. Both approaches were compared by calculating the number of vehicles that pssed the artery in a prescribed time.

Opis:
The paper deals with microscopic modeling of the traffic flow using cellular automaton in the Tunnel Simulator based on PLC. Model with lane changing logic is implemented in the SCADA visualization screen of the tunnel with unidirectional two-lane traffic. Tunnel Simulator is able to simulate unexpected events in the road tunnel such as fire, so vehicle type is also included in the traffic model to specify the heat release rate of the fire for car, van, bus and truck fi re scenario. Number of persons in the vehicles and location of the persons in the tunnel are planned to be used as the input for the model for evacuation time estimation.

Opis:
The paper presents two visualization applications that enable to visualize traffic flow simulation results obtained with the TRANSIMS system. The applications, designed and implemented at the Institute of Machines and Motor Vehicles of Poznan University of Technology, are written in Java and, as freeware, can be used free of charge. Both visualizers use GIS-based data manipulation techniques to provide precise and customizable 2D visualization. First, the problem of traffic flow modeling and simulation, and the TRANSIMS system were introduced. Then a general design and features of both applications were described. In order to demonstrate the most essential capabilities of the tools, the author presented an example of visualization of traffic in a segment of a real urban network.
