Recent years saw immense growth in performance measurement literature related to public transit systems, with a clear segmentation between financial and quality-of-service performance frameworks. Recently, there has been a shift away from considering cost efficiency alone as a performance measure, and quality-of-service – which influences ridership attraction and retention – has been receiving more interest. The segmentation of these two performance aspects poses a gap in the literature, as there are interdependencies between them. This study provides a systematic review of the methodologies and empirical findings of studies on both performance measurement aspects of urban rail transit systems; specifically, we demonstrate the importance of linking cost efficiency analyses to the level of service quality. To our knowledge, this is the first review of urban rail transit research that links the two performance aspects. We begin by reviewing the methodological limitations of cost performance measures and summarising the drivers of cost performance in the existing literature. We then review studies on the definitions and measurements of quality-of-service in urban rail performance. Lastly, we summarise the scant literature linking the two performance aspects and highlight future study directions, mainly, the importance of a structural framework to provide a holistic view of transit operators’ performance.

The relationship between commuting behaviours and subjective wellbeing has been fascinating scholars of different disciplines. Especially in the last decade, longitudinal research designs have made great progress in identifying causality in the commuting-wellbeing relationship by focusing on within-individual variations over time. However, the results from longitudinal research are far from consistent and, therefore, questions remain unanswered regarding the association of motorised and long commuting journeys with subjective wellbeing in the long term. The aim of this literature review is to account for why these inconsistencies occur and to provide some avenues for future longitudinal research. We achieve this by developing theoretical conceptualisations of the commuting-wellbeing relationship from an interdisciplinary perspective, which drives the subsequent critical review of empirical longitudinal evidence based on nation/city-wide panel surveys, intervention experiments and relocation events. We recommend furture research to distinguish and integrate different processes that lead to changes in commuting behaviours, including environmental changes, information or participatory interventions, and the event of residential relocation together with other life events and long-term processes in life. This processual thinking will enrich the temporal scope of longitudinal research and contribute to a better understanding of the interdependent relationship between daily commuting behaviours and long-term subjective wellbeing.

Demand responsive transit (DRT) echoes the new requirements of modern travel on flexibility and carbon reduction, as well as achieving a better match between demand and supply. However, many DRTs still failed. An important step named adaptability analysis helps to understand the context, desirability, and feasibility of introducing DRT. An adaptability analysis includes three sub-questions. Question 1 focuses on policy, regulation, funding, and technologies. Question 2 looks at the interactions of travel demand with operation parameters such as fare and fleet size. Question 3 tries to figure out the impacts of DRT on mobility, society, and the environment. To answer Question 1, macro-level methods collect information and generalise from empirical knowledge, including experience and barriers from real-world operation cases. To answer Question 2, meso-level methods determine the operation mode of DRT by quantifying related factors and establishing evaluation models or boundary condition decision models. To answer Question 3, micro-level methods use microscopic models for simulating the interaction between passengers and vehicles under different scenarios. This paper further discusses the advantages, disadvantages, and future directions of adaptability analysis methods of DRT. Overall, DRT presents great potential and future adaptability analysis should be developed by considering new trends in DRT and more complex and practical-oriented scenarios.

Infrastructure for active travel (AT) is receiving attention as a low-cost, sustainable transport option that promotes physical activity. However, the planning and implementation of new AT infrastructure often brings challenges. This review synthesises stakeholders’ views and experiences of developing guidance for, designing, commissioning and implementing environmental interventions to promote AT. Eight databases were searched for studies containing qualitative data from stakeholders with direct experience. Results were synthesised thematically. The risk of bias was assessed using the CASP checklist for qualitative research, and evidence quality using the GRADE-CERQual tool. A total of 21,703 articles were identified from database searches, with 35 studies included. Eighteen studies focused on infrastructure promoting walking and cycling, fourteen on cycling and three on walking. Fifteen studies were judged to have no/very minor concerns, 12 had minor concerns, four had moderate concerns and four were of serious concern. A variety of stakeholders were influential, most commonly supportive elected leaders and individuals in public and voluntary sectors. Inter-disciplinary collaboration facilitated sharing of expertise and resources, and upskilling was beneficial. Effective communication methods varied between stakeholders and reason for communication. Persuasive strategies included aligning with stakeholders priorities and making the best use of evidence. Opportune moments to implement AT infrastructure were alongside non-AT projects and exogenous events. Compliance with AT policies could increase by embedding in higher level legislation. Political support was important and fostered through not de-prioritising cars and gaining external funding. The GRADE-CERQual found high confidence in our findings, apart from the sub-themes “Methods of communication” and “Political will” that had moderate confidence. Our findings can assist stakeholders in successfully navigating the process from conception to implementation of AT infrastructure and inform future policy and decision-making.

Recently, a growing body of literature has focused on the role of daily mobility on subjective well-being (SWB). What is less well understood is the temporal effect of commuting on SWB/life satisfaction. To date, most studies addressing this temporal effect consider the impact of a residential relocation and not many studies reflect on the impact of a workplace relocation (WPR) on commuting behaviour, commuting satisfaction and SWB. This is surprising considering that changes at the destination of a commuting trip (i.e. relocation of the workplace) could be as important as changes at the origin of a commuting trip (i.e. relocation of the place of residence). This paper, therefore, aims to provide a systematic review of the impact of a WPR on commuting behaviour, commuting satisfaction and SWB. Using the PRISMA method, we identified 35 papers and developed a conceptual model summarising the main relationships between workplace relocation, commuting behaviour, commuting satisfaction and SWB. This conceptual model also reflects four disciplinary perspectives dominating research on the impacts of a workplace relocation.

Contemporary shopping is experiencing rapid changes with the increasing ubiquity of technologies that can be utilised to create seamless omni-channel experiences. These changes have logistics-related implications for end-consumers. Adopting Bowersox (1978)’s [Logistics management. New York: Macmillan] categorisation of logistics activities, this study comprises a synthesised review of scattered consumer logistics literature to bring order and structure to this evolving research field. It is found that an omni-channel shopping environment enables the dynamic transfer of logistics activities between business operators and consumers; However, this interaction does not extend to the post-shopping last-mile context. Instead, last-mile logistics is characterised by a somewhat rigid extension/shift of logistics obligations to/from consumers. Additionally, the COVID-19 pandemic has given rise to a self-service and technology-dependence trend in consumer logistics, leading to the more active control of logistics activities by consumers. Four propositions along with a unified framework are proposed, based on which a list of future research questions is suggested.

Many communities have been marginalised in the ongoing policy and planning debates surrounding transportation electrification, even though well allocated charging infrastructure is essential for the environmental and societal benefits of Electric Vehicles (EVs) to be realised. This scoping review aims to synthesise the current state of knowledge and gaps surrounding transportation equity in EV charging research. Following PRISMA-Scr protocols, a literature search is conducted to locate articles that explicitly or implicitly discuss EV charging equity. Our review finds that research on charging equity is nascent and lacking in clear normative evaluations of equity compared to the wider body of transportation equity literature. Only slightly more than one-in-four of an identified 37 articles discuss equity and justice explicitly. Equity perspectives in charging research are dominated by North American and European perspectives, with limited perspectives from the rest of the world. Charging incentivisation schemes and planning efforts may not be equity focused and may favour wealthier individuals, and there are differences in the charging needs and desires of high adoption groups compared to low adoption groups. These findings, however, often come from geographically and philosophically limited contexts and there are gaps in the literature for new methodological and topical contributions to this area.

Riding a bike for transport purposes is an effective way to improve population and environmental health. Despite this, participation levels in many countries are low. Identifying the barriers and enablers to riding a bike for transport is essential to developing interventions that encourage bike riding. In this mixed-methods systematic review, we aimed to identify the perceived barriers and enablers to adults riding a bike for transport in Organisation for Economic Development (OECD) countries. A systematic database search was conducted to identify relevant peer-reviewed and grey literature. Fourty-five papers/reports met eligibility criteria. There were 34 barriers and 21 enablers identified. The leading barriers related to riding on the road alongside motor vehicles. Other factors identified included the provision and quality of cycling infrastructure, personal factors such as physical fitness, attitudinal factors such as community perceptions of cyclists, and environmental factors. While this review highlights the complexity of factors that influence the uptake of riding a bike for transport, many of the leading factors could be overcome through the provision of high-quality protected infrastructure for bike riders. Other interventions to address other known barriers and enablers are needed to increase the uptake of bike riding.

This systematic review focuses on factors associated with occupational road crashes among professional drivers of commercial vehicles, e.g. trucks, buses and taxis. PubMed, MEDLINE and Google Scholar were searched, and quality assessment followed guidelines developed by the British Sociological Association medical sociological group. Sixty-six cross-sectional studies and one cohort study were included, of which 18, 45 and 3 studies were categorised as high-, moderate- and low-quality studies, respectively. Twenty-seven significant risk factors for road crashes were divided into six domains: (1) organisational, (2) individual driver characteristics, (3) qualifications, (4) driver conditions, (5) driving behaviour, and (6) external. The most frequently investigated factors were age (individual driver characteristics domain), sleepiness and substance use (driver conditions), driving duration and time of driving (organisational). More recently studied risk factors were management support (organisational), years of experience (qualifications), health parameters (driver conditions), vehicle speed and distracting activities, e.g. use of phone or navigation tools while driving (driving behaviour). The review identified overall risk factor domains and occupation-specific risk factors suitable for targeting and prioritising organisational preventive safety efforts. To obtain a more in-depth understanding of the antecedents of road crashes, future prospective studies are encouraged that evaluate preventive strategies for occupational road crashes.
