This paper describes architecture of the novel implementation of the Forth interpreter-compiler. The architecture follows the object- and component-oriented design paradigms. The implementation is done with the modern C++ 20 language taking full advantage of such constructs as lambda functions, variadic templates, as well as the coroutines and concepts. The system is highly modular and easily scales for small footprint embedded systems. We propose to extend Forth with the coroutine words that allow for async operations and lightweight cooperative multi-threading. We show successful deployment of the proposed Forth implementation on three platforms, two PC frameworks running Linux and Windows, respectively, as well as on tiny embedded system NodeMCU v3 with the 32-bit RISC ESP8266 microprocessor and 32/80KB memory. The project has also educational value, showing intrinsic operation of Forth and modern C++. Software is available free from the Internet.

The aim of this paper is to study the large-time behaviour of mild solutions to the one-dimensional cooperative systems with anomalous diffusion when at least one entry of the initial condition decays slower than a power. We prove that the solution moves at least exponentially fast as time goes to infinity. Moreover, the exponent of propagation depends on the decay of the initial condition and of the reaction term.

After several years of extensive research and standardization both in Europe and North America, cooperative systems based on vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication (V2X) are entering the phase of initial deployments. The basic technology feasibility of IEEE 802.11p wireless communication has been proven and several Field Operational Tests (FOT) across the globe are preparing the actual deployment. In order to benefit by the significant improvements enabled by the V2X use cases in terms of traffic safety and efficiency, the system has to operate reliably under high traffic loads providing a robust security scheme and a viable business case for all stakeholders. In addition, the cooperative nature of V2X requires new ways of data management in the traffic management centers (TMCs). TMCs will have to process large amounts of dynamic real time data, to aggregate these data with fixed sensor data and transmit location based traffic information dynamically to the traffic participants. The paper gives an up-to date overview of current projects, standardization, and system architecture of V2X cooperative systems.

Po kilku latach intensywnych badań i standaryzacji, zarówno w Europie, jak i w Ameryce Północnej, współdziałające systemy oparte na komunikacji pojazd z pojazdem (V2V) oraz pojazd-infrastruktura (V2I) -czyli generalnie (V2X) - wchodzimy w fazę pierwszych wdrożeń. Została potwierdzona możliwość zastosowania podstawowej technologii bezprzewodowej komunikacji 802.11p IEEE i na całym świecie jest przygotowywane wdrożenie fazy testowania w warunkach eksploatacyjnych (FOT). W celu spożytkowania znaczących udoskonaleń w zakresie bezpieczeństwa ruchu i wydajności dzięki wprowadzaniu komunikacji V2X , system musi funkcjonować niezawodnie przy dużych obciążeniach ruchu gwarantując istotną poprawę bezpieczeństwa oraz możliwości biznesowe dla wszystkich interesariuszy. Dodatkowo, sposób działania systemu V2X wymaga nowych metod zarządzania danymi w centrach zarządzania ruchem (TMCS). TMCS musi przetwarzać duże ilości dynamicznych danych w czasie rzeczywistym, w celu zbierania tych danych z określonych czujników i przekazywania ruchowych informacji lokalizacyjnych w sposób dynamiczny uczestnikom ruchu. Dokument przedstawia aktualny status bieżących projektów, stanu standaryzacji i architekturę systemów współpracujących V2X.

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.

Modern Intelligent Transport Systems (ITS) are now being widely deployed; in order to ensure that these deployments will bring maximum benefit to end users and other stakeholders, an ITS architecture, which defi nes how the deployed system would fi t into overall ITS structure, has to be defi ned. Help is available to achieve these goals from the European ITS Framework (FRAME) Architecture, now being upgraded by the European project E-FRAME. Within this project also the importance of mutual influence between standards and architecture is judged.
