A review of transportation carbon emissions research using bibliometric analyses

The transportation sector is one of the major sources of global carbon emissions.In this study,a bibliometric analysis was conducted using CiteSpace and VOSviewer for articles published in the field of transportation carbon emissions(TCEs)between 1997 and 2023.From this analysis,our research shows that:(a)the number of articles on TCEs has grown rapidly since 2010;(b)China,the United States,and the United Kingdom are important research forces,with the Helmholtz Association of German having the highest number of publications;(c)Transportation Research Part D:Transport and Environment is the most cited journal in this field;(d)the current research hotspots mainly focus on theory and methodological approaches,low-carbon travel,green supply chain management,and carbon emission drivers;(e)while,scenario analysis,data envelopment analysis,and vehicle routing problem are popular keywords that have been used in the research field of TCEs in recent years.Finally,using current research trends,our study also proposes a series of future research endeavors for the field of TCEs.

Food-delivery behavior under crowd sourcing mobility services

The rapid development of the online food-delivery industry,has led to not only increases in the number of the crowd-sourced shared food-delivery service drivers on our roads,but also growing urban traffic safety management concerns.This study investigates the decision-making behaviors that exist between delivery drivers,their food-delivery platform and their potential impact on traffic safety.Using the evolutionary game theory,stakeholder decision-making behaviors involving traffic safety within the food-delivery industry were analyzed.From our analysis,several behavioral influencers were identified,including penalties for traffic violations,the opportunity cost of delivery drivers complying with traffic rules,the costs associated with risk and strict management approaches,reputation incentives,costs related to the delivery platform being punished,the probability of compliance with traffic rules,and the probability of adopting a strict management approach by the delivery platform.Our study demonstrates that stabilization strategies used by the food service industry differ when the types of government control measures also differ.When the government takes a more aggressive approach to regulation and control,compliance with the traffic rules and the adoption of strict enforcement measures by management are the only evolutionary stability strategies available to food-delivery platforms.As part of a strict management strategy,appropriate compensation or incentive measures should be provided by the distribution platform.Furthermore,the fines given for traffic violations should be increased to create a safer road environment that has fewer traffic accidents involving food-delivery drivers.
