The modeling of a new generation of agent-based simulation systems supporting pedestrian and crowd management taking into account affective states represents a new research frontier. Pedestrian behaviour involves human perception processes, based on subjective and psychological aspects. Following the concept of pedestrian environmental awareness, each walker adapts his/her crossing behaviour according to environmental conditions and his/her perception of safety. Different pedestrian behaviours can be related to subjective mobility and readiness to respond, and these factors are strongly dependent on the subjective interaction with the environment. Having additional inputs about pedestrian behaviour related to their perception processes could be useful in order to develop a more representative pedestrian dynamic model. In particular, the subjective perception of the safeness of crossing should be taken into consideration. In order to focus on the pedestrians’ perception of safe road crossing and walking, an experiment in an uncontrolled urban scenario has been carried out. Besides more conventional self-assessment questionnaires, physiological responses have been considered to evaluate the affective state of pedestrians during the interaction with the urban environment. Results from the analysis of the collected data show that physiological responses are reliable indicators of safety perception while road crossing and interacting with real urban environment, suggesting the design of agent-based models for pedestrian dynamics simulations taking in account the representation of affective states.

安全感知和行人动态:针对情感主体建模的实验结果

考虑到情感状态的支持行人和人群管理的新一代基于代理的仿真系统的建模代表了一个新的研究前沿。行人行为涉及基于主观和心理方面的人类感知过程。遵循行人环境意识的概念,每个行人都根据环境条件和他/她的安全感来适应其过路行为。不同的行人行为可能与主观活动能力和响应意愿有关,而这些因素在很大程度上取决于与环境的主观互动。为了开发出更具代表性的行人动态模型,与行人行为相关的与他们的感知过程相关的其他输入可能会很有用。特别是,应考虑对过境安全性的主观看法。为了专注于行人对安全过马路和步行的感知,已经在不受控制的城市场景中进行了实验。除了更常规的自我评估问卷以外,还考虑了生理反应来评估行人与城市环境互动过程中的情感状态。对收集到的数据进行分析后得出的结果表明,在穿越和与实际城市环境互动时,生理反应是安全知觉的可靠指标,这表明设计基于代理人的模型进行行人动力学模拟时要考虑情感状态的表示。为了专注于行人对安全过马路和步行的感知,已经在不受控制的城市场景中进行了实验。除了更常规的自我评估问卷以外,还考虑了生理反应来评估行人与城市环境互动过程中的情感状态。对收集到的数据进行分析后得出的结果表明,在穿越和与实际城市环境互动时,生理反应是安全知觉的可靠指标,这表明设计基于代理人的模型进行行人动力学模拟时要考虑情感状态的表示。为了专注于行人对安全过马路和步行的感知,已经在不受控制的城市场景中进行了实验。除了更常规的自我评估问卷以外,还考虑了生理反应来评估行人与城市环境互动过程中的情感状态。对收集到的数据进行分析后得出的结果表明,在穿越和与实际城市环境互动时,生理反应是安全知觉的可靠指标,这表明设计基于代理人的模型进行行人动力学模拟时要考虑情感状态的表示。除了更常规的自我评估问卷以外,还考虑了生理反应来评估行人与城市环境互动过程中的情感状态。对收集到的数据进行分析后得出的结果表明,在穿越和与实际城市环境互动时,生理反应是安全知觉的可靠指标,这表明设计基于代理人的模型进行行人动力学模拟时要考虑情感状态的表示。除了更常规的自我评估问卷以外,还考虑了生理反应来评估行人与城市环境互动过程中的情感状态。对收集到的数据进行分析后得出的结果表明,在穿越和与实际城市环境互动时,生理反应是安全知觉的可靠指标,这表明设计基于代理人的模型进行行人动力学模拟时要考虑情感状态的表示。
