The literature on pedestrian modeling and simulation models is surveyed, with an emphasis on emergency situations. The state of the art is organized and presented from this perspective. Strong points and gaps in the literature are identified. The parameters that are relevant in modeling pedestrian movement are organized in a new framework and analyzed. Specific properties and characteristics of modeling emergency situations are considered, and applications of available data collection options are surveyed. This work can support researchers and practitioners interested in conducting pedestrian modeling and simulation research and applications, both general and targeted to emergency situations.

After analyzing the loader duty cycle with hybrid drive theory and gaining the characteristics of loader duty cycle, an integrated started generator-ISG based coaxial parallel hybrid loader is designed. Two simulation models are built with the simulation software Cruise, one is tradition loader another is hybrid loader. The simulation result of tradition loader model compare with the test data to amend the model. To gain same accuracy, the hybrid loader model is rebuilt based on the tradition loader model. According to the “I” type duty cycle, comparing the simulation result of tradition and hybrid loader, the result shows that hybrid loader can save fuel 10.4%.

Pedestrian Simulation

Analyzing the pedestrian subconscious behavior and walking environment in the passage, right-moving preference subconscious strength and overtaking subconscious strength are introduced into the pedestrian simulation model which is based on lattice gas model. Two pedestrian subconscious behavior simulation models, which are distinguished by whether considering pedestrian flow ratio of two directions or not, are established respectively. With the platform of MATLAB software, the simulations of pedestrian counter flow subconscious behavior are realized. The simulations indicate that compared with the pedestrian subconscious behavior simulation model without considering the pedestrian flow ratio of two directions, the model that considers the pedestrian flow ratio of two directions is better in simulating the pedestrian subconscious behavior.

New Framework

Traditionally, simulation has been used as a tool of design to estimate, compare and optimize the performance of different system designs. It is rarely used in making real-time decisions due to the long computation delay of executing simulation models. However, with the fast growth of computing capability, we have observed more and more works on reusing simulation efforts for repeated experiments with the help of data analytics tools, and the target of these works is to solve real-time decision problems. In this paper, we distill the important features of these works and summarize a new simulation framework, called offline-simulation-online-application (OSOA) framework, which treats simulation as a data generator, applies state-of-the-art analytics tools to build predictive models, and then uses the predictive models for real-time applications. In this paper, we illustrate how to apply the OSOA framework on estimation, ranking and selection and simulation optimization, and provide a prospect of this new framework.

In state of the art research a growing interest in the application of agent models for the simulation of road traffic can be observed. Software agents are particularly suitable for the representation of travellers and their goal-oriented behaviour. Although numerous applications based on these types of models are already available, the options for modelling and calibration of the agents as goal-oriented individuals are either simplified to aggregated parameters or associated with overly complex and opaque implementation details. This makes it difficult to reuse available simulation models. In this paper, we demonstrate how the combination of persona models together with semantic methods can be applied to achieve a well-structured agent model that allows for improved reusability.

Pedestrian Simulation

Modelling and simulating pedestrian motions are standard ways to investigate crowd dynamics aimed to enhance pedestrians’ safety. Movement of people is affected by interactions with one another and with the physical environment that it may be a worthy line of research. This paper studies the impact of speed on how pedestrians respond to the obstacles (i.e. Obstacles avoidance behaviour). A field experiment was performed in which a group of people were instructed to perform some obstacles avoidance tasks at two levels of normal and high speeds. Trajectories of the participants are extracted from the video recordings for the subsequent intentions:(i) to seek out the impact of total speed, x and yaxis (ii) to observe the impact of the speed on the movement direction, x-axis, (iii) to find out the impact of speed on the lateral direction, y-axis. The results of the experiments could be used to enhance the current pedestrian simulation models.

Для задач синтеза сценариев управления региональной безопасностью в условиях кризисных ситуаций разработана технология интегральной оценки безопасности региональных социально-экономических систем. Предложена формализованная постановка задачи и ее декомпозиция с учетом набора ключевых показателей безопасности. В отличие от известных формальных моделей устойчивого развития технология обеспечивает формирование матричного интегрального показателя региональной безопасности и позволяет оценить состояние и тенденции развития региона за счет совместного использования системно-динамических, нечетких и вероятностных моделей оценки индикаторов безопасности. С применением разработанной технологии построена матрица региональной безопасности Арктической зоны РФ. For management scenario synthesis of regional security under emergency situations problem-solving a technology for security integral estimation of the regional socio-economic systems has been developed. The formalized problem statement and it decomposition subject to the set of key security indicators have been proposed. In contrast to well-known and state-of-the-art formal models of sustainable development the technology provides matrix integral index formation of regional security and allows situation and tendencies assessment of regional development at the expense of joint use of system-dynamic, fuzzy and probabilistic estimation models of security indicators. With application of developed technology the regional security matrix of Arctic region of Russian Federation has been designed.
