An approach to manage human performance related risks in petrochemical sector is to use human reliability analyses (HRA) techniques. However, the focus of HRAs on individuals and on decomposed tasks overlooks the likelihood that collective actions and behaviors might lead to system failures. This study introduces an alternative approach, referred to as Human Performance Integrity (HPI) index, to assess human performance conditions on the whole, as they relate to safety, in petrochemical facilities. Additionally, the approach is used to rate installations in terms of their defenses against safety‐relevant human failures. The HPI index is built upon the notions of Cognitive Reliability and Error Analysis Method. By means of a 42‐question survey, data was collected on the factors that improve or reduce human performance in 11 oil refineries. Data was used to assess the facilities' safety performance. Results were compared against information obtained from relevant investigation reports, as well as and an independent evaluation of the facilities carried out by certified auditors. Findings support the use of HPI index from novice and experienced scholars and/or practitioners as a quick and effortless, yet sound and efficient manner to assess safety and reliability performance of oil refineries from a human factors perspective.

Evacuation modelling has developed over time from simple engineering equations that do not consider behavioral tendencies to more sophisticated models with the potential to represent evacuation behaviors and decisions. This paper aims to lay the foundations for a more realistic representation of human factors in evacuation models, which is needed to ensure the adequacy of the infrastructure, decision processes and safety of evacuation. To provide a clearer picture of the empirical knowledge and modelling for evacuation studies, a generalized timeline is introduced. Recent behavioral evidence from empirical studies in the fields of both pedestrian evacuation and vehicular evacuations are reviewed to investigate the impact of various factors on the evacuee behavior over different phases. The consensus perspective on key behaviors that emerges is then used to review and consolidate the recent advances in evacuation modelling, in particular with respect to the formulations and techniques for representing these behaviors. Within each of these discussions, we pointed to current limitations and make corresponding suggestions on future research directions.

Autonomous vehicles are anticipated to play an important role on future mobility offering encouraging solutions to today’s transport problems. However, concerns of the public, which can affect the AVs’ uptake, are yet to be addressed. This study presents relevant findings of an online survey in eight European countries. First, 1639 responses were collected in Spring 2020 on people’s commute, preferred transport mode, willingness to use AVs and demographic details. Data was analyzed for the entire dataset and for vulnerable road users in particular. Results re-confirm the long-lasting discourse on the importance of safety on the acceptance of AVs. Spearman correlations show that age, gender, education level and number of household members have an impact on how people may be using or allowing their children to use the technology, e.g., with or without the presence of a human supervisor in the vehicle. Results on vulnerable road users show the same trend. The elderly would travel in AVs with the presence of a human supervisor. People with disabilities have the same proclivity, however their reactions were more conservative. Next to safety, reliability, affordability, cost, driving pleasure and household size may also impact the uptake of AVs and shall be considered when designing relevant policies.

Maintenance is a major component of complex transportation systems safe and undisturbed operation. Despite technological advancements, maintenance tasks and procedures rely heavily on the performance of maintenance personnel. Alas, due to the complexity and often limited time to perform and complete maintenance tasks, as well as the usually difficult working conditions, maintenance personnel is prone to error. Attention to human factors can, therefore, strengthen the performance of the personnel and minimise the likelihood of maintenance related incidents and accidents. This chapter contributes to the discourse of maintenance considerations in transportation systems by concisely discussing the human factors involvement in the maintenance procedures, offering a systematic approach to address human factors in maintenance operations, and presenting the factors that affect the performance of maintenance personnel. We expect our view to be instrumental for all stakeholders involved with maintenance of transportation systems.
