Theoretical Analysis of the Worker’s Movement Prediction in Construction Sites and Their Stress Level for the Dangerous Situation Prevention

Abstract

The occupational risk assessment methodology called Level of Preventive Action (Lpac) evaluates the amount of preventive action to obtain an optimal prevention level, measuring the degree of danger concerning the building geometry, the worker position concerning the slab edge and the worker’s emotional states. The mathematical basis of Lpac can be extended to include the perspective of collective behaviour models, which can describe the predictable human behaviour based on the probability of acts. Research in the mathematical field satisfactorily models the movement that individuals follow or will follow in different scenarios (e.g., street crossing, emergency evacuation), including social parameters such as mood and emotions. This paper presents a theoretical case applied to the predictive analysis of behaviours and interactions between individuals working on constructing a slab. It is essential to include the worker’s movement prediction regarding unsafe acts and movements in the risk assessment and add the emotional states. From a case study at the microscopic level, stress can trigger dangerous situations, and its evaluation can prevent them.
