Conceptual model of the automated pedestrian simulation system for unmanned vehicles and ADAS systems testing

The development of pedestrian simulation systems requires the acquisition of empirical evidences about human behaviour for sake of model validation. In this framework, the paper presents the results of an on field observation of pedestrian behaviour in an urban crowded walkway. The research was aimed at testing the potentially combined effect of ageing and grouping on speed and proxemic behaviour. In particular, we focused on dyads, as the most frequent type of groups in the observed scenario. Results showed that in situation of irregular flows elderly pedestrians walked the 40% slower than adults, due to locomotion skill decline. Dyads walked the 30% slower than singles, due to the need to maintain spatial cohesion to communicate (proxemics). Results contributed to refine the parametric validation of the agent-based simulation system ELIAS38.

Oriented Approach

This paper documents a real-time storm sewer simulation system (RTS4) in conjunction with a Storm Water Management Model (SWMM) based on a pattern-oriented approach. The RTS4 is initiated by system analysis ascertaining functional requirements, which is sequentially followed by conceptual model, pattern languages, concrete pattern-based design, implementations and applications. The proposed conceptual model helps sketch out a core software skeleton in relation to prior system requirement analysis. Of the proposed pattern languages, each can be regarded as a ‘building block’ on which the concrete pattern-based design is built. Finally, the RTS4 is implemented by following the proposed pattern-oriented design. The applicability of RTS4 is demonstrated with respect to storm sewer simulation and real-time operations. The results of the simulation show that the proposed pattern-oriented approach offers a promising basis for software system developments such as RTS4.

The military conceptual model (MCM) provides an unambiguous and credible reference for the development of the combat simulation system. According to the characteristics and regularities of the tactical decision-making (TDM) process, this process is divided into five abstract stages, which analyze the modeling method of the simulated military conceptual model in detail. This method reduces the common attributes and action of the TDM entity to that of a super one, which avoids the appearance of a multi-inheritable complex construction. Then the super TDM entity is analyzed so as to obtain a description of its properties and action. By summing up the functions of the TDM simulation entity, it can point out that this modeling method has very strong feasibility.
