The emergence of dynamic rerouting in multi-modal transportation networks has emerged as a crucial area in operations research, revolutionizing routine optimization. The review study analyzes multiple research publications on algorithms and techniques related to dynamic rerouting to give a thorough summary of the state of research in this field and provide future suggestions. The research paper explains the importance of dynamic rerouting in modern transportation systems and recognizes its critical role in tackling issues like accidents, traffic congestion, and infrastructure constraints. In addition, the review examines the development of dynamic rerouting techniques by examining several studies to uncover the theoretical foundation, technological developments, and effects of the practices on various forms of transportation. The paper emphasizes the potential of technological advancements such as artificial intelligence, the Internet of Things, and big data in transforming routing efficiencies. Further, the review presents specific difficulties and best practices for each mode of transportation, highlighting the many uses of dynamic rerouting in air, sea, rail, and road transportation. The review also digs deeper into the integration barriers common in multi-modal networks, highlighting successful case studies that overcome these obstacles as well as strategic approaches and regulatory modifications. Lastly, the research paper assesses the impact of dynamic rerouting on urban development, sustainability, and potential directions for future research such as the integration of large language models. The comprehensive literature review incorporates multiple research perspectives to offer significant insights into the efficacy, challenges, and potential future pathways for dynamic rerouting within multi-modal transportation networks.

An initial proposed list for standardized terms and definitions that describe the status and operation of automated driving systems and advanced driving assistance systems is presented in this publication, with the intent of seeding a broader related discussion within larger organizations that can champion the development of more formal best practices or standards.

Risk perception may be measured in different, separate environments. For example, drivers and pedestrians assess the risks in the road environment and workers assess the risks in the workplace environment. The purpose of this study is to examine the relationships between the risks perceived in several different environments in order to examine whether separate environments – such as the workplace environment and the road environment – are perceived as distinct environments, and whether the knowledge gained by learning to assess risks in one environment can be transferred to a new one. This study found a relationship between measures of risk perception while driving and a while crossing a road. Another finding is that a relationship was observed between the perception of risks related to vaccines and those related to medication, and a relationship was also observed between measures of risk perception while browsing the Internet and while using social media. The relationships between the measures of risk perception while crossing a road and the measures of risk perception while hiking in nature or in the workplace are small, as are the relationships between health-related risks and stock market-related risks. These findings suggest that separate environments, such as the workplace environment and the natural environment, are perceived as distinct environments from the road environment, and that knowledge learned in one environment cannot be transferred and used when in the other environment. The findings are discussed in the context of digital classroom learning.

The Federal Aviation Administration (FAA) is considering implementation of a balanced mix design method (BMD) for asphalt concrete (AC) of airfield pavements in a future specification update. One of the key elements towards implementing BMD, is setting adequate conditions for laboratory mechanical testing that best simulate actual field conditions. In this study, representative air void (AV) levels were identified for laboratory mechanical testing by analyzing quality control (QC) data of plant-mixed laboratory-compacted (PMLC) samples along with in-place density measurements for multiple existing airfield pavements. The laboratory compaction effort in the Superpave Gyratory Compactor (SGC) required to reach the recommended AV levels were evaluated for different specimen heights. The specimen height and AV level were then experimentally verified with the Ideal Rutting test (ASTM D8360-22) for these airfield mixtures. Based on analysis of field density, laboratory compaction effort, and mechanical test data, it was recommended to test 62 mm thick gyratory specimens at 7±0.5% AV (directly molded) or at 5±0.5% AV (after cutting), which should help capture the different aspects of the asphalt mixture’s resistance to rutting in terms of aggregate skeleton and binder properties.

While infrastructure planning guidelines frequently emphasise the need of comprehensible, easy to use or unambiguously understandable infrastructure, they lack information on how to design such intuitively usable cycling infrastructure. Furthermore, while cyclists already criticise the current traffic system not to be intuitively usable, this issue will be even more relevant as cycling usage may increase in the next years. Thus, this paper presents a systematic literature review to identify studies that already investigated the intuitiveness of cycling infrastructure. Furthermore, this study aims to identify major research gaps. Searching three databases with a predefined set of keywords resulted in more than 1300 titles. Applying inclusion and exclusion criteria, eleven titles remained in the last review step and were analysed in detail. Results show that these studies use a variety of methods and terms to describe and investigate intuitiveness of various cycling infrastructure designs. Conclusions from these studies range from very specific infrastructure design recommendations over highly general design advices to recommendations that do not refer to infrastructure design at all. Three main research gaps were identified. Firstly, there are various infrastructure types that have not been covered by the studies. Furthermore, there is a need for basic research on how to apply principles of intuitive design to cycling infrastructure design in general. Lastly, a large amount of research investigated behavioural responses to infrastructural changes but was not designed to specifically assess intuitiveness. Thus, there are large research gaps to be filled by upcoming studies to design intuitively usable cycling infrastructure.

Bike-sharing systems allow occasional and regular users to move by replacing other transport modes for the same trip or generating a new journey. Our research assesses the demand for Lisbon’s public dock-based bike-sharing system (BSS) users named after GIRA. This paper aims to identify the determinant factors that influence the potential of the BSS to generate new trips or replace previous modes using a binary logit model based on a survey of 3112 BSS users. The survey results indicate that GIRA generated approximately 20% of the BSS trips, i.e., they would not have been realized if GIRA did not exist. The remaining BSS trips replaced other motorized (55%) and non-motorized (25%) trips. The main determinants explaining a higher likelihood of replacing other modes are having a yearly GIRA pass and a bike-sharing station within a 5-min walking distance. In contrast, regular car users are more likely to generate new trips, suggesting they use bike-sharing for recreational purposes. The findings provide policymakers with an assessment of the determinants that can influence bike-sharing users to generate or substitute trips from other modes for bike-sharing and, consequently, give policies to potentially increase bike-sharing mobility share.

This reflective paper elucidates the thought-making process of the author in understanding and putting into context the environmental consciousness of childhood and the self-concept. The axiom that can be yielded in the paper is the quiet role of childhood in facing the environmental challenges the world faces for the longest time.

Air traffic controllers play a vital function with regard to ensuring the safety and efficiency of international civil aviation. Despite this, there is a lack of research addressing how air traffic controllers are trained. This paper collects opinions about the air traffic control (ATC) training programme in Singapore from a group of 30 instructors who were working within the aerodrome training team. Convenience sampling was used to recruit the participants and thematic analysis was used to identify key opinions. Significant advantages and disadvantages of the current training programme were identified, such as pre-training and simulator constraints. In addition to findings relating to the learning of required skill sets, interviews also highlighted the need for a just culture in the workplace and human factors training.
