The COVID-19 pandemic represents a substantial global health problem for humanity in modern times. Disruptions of a fundamental nature have impacted the global transportation system, supply chains, and trade. Huge revenue losses in the transport sector were a direct consequence of the lockdowns. A scarcity of studies currently exists regarding the road transport sector's reaction to the COVID-19 pandemic. Nigeria is analyzed as a case study to demonstrate the gap-filling methods in this paper. This study utilized a mixed-methods design, which integrated qualitative and quantitative research strategies. By using Principal Component Analysis and Multiple Criteria Analysis, the data was effectively analyzed. The study's results show that Nigeria's road transport operators are highly confident (907%) in the ability of 51 new technologies, innovations, processes, and procedures to protect themselves and passengers from the COVID-19 pandemic. Road transport operators' analysis of the pandemic response suggests that observing the lockdown directive is the most effective measure, as evidenced by a breakdown. As the breakdown proceeds, COVID-19 safety protocols are prioritized less, followed by environmental sanitation, hygiene promotion, information technology, facemasks, and concluding with social distancing. Other avenues include public enlightenment, palliative care, inclusion, and the use of mass media. This finding unequivocally supports the effectiveness of non-pharmaceutical strategies in the battle against the pandemic. The study's outcomes affirm the practicality of implementing non-pharmaceutical guidelines for controlling the COVID-19 pandemic in Nigeria.

In response to COVID-19, stay-at-home orders triggered a change in traffic patterns, transforming major roadways into less congested routes during the busiest periods of travel. Crash data from February to May 2020 in Ohio's Franklin County, supplemented by speed and network data, is analyzed to determine the impact of this transformation on traffic safety. Under the stay-at-home guidelines, an analysis of crash characteristics including crash type and time of occurrence was performed. This analysis yielded two models: (i) a multinomial logistic regression model to study the link between daily traffic volume and crash severity, and (ii) a Bayesian hierarchical logistic regression model investigating the association between increased average road speeds and elevated crash severity, factoring in the possibility of a fatal accident. The findings indicate a pattern where smaller volumes are associated with a more significant degree of severity. In the context of the pandemic response, an opportunity arises to explore the underpinnings of this effect. Data indicated that higher speeds frequently corresponded with more severe accidents, a reduced percentage of accidents occurring during the morning rush hour, and a decrease in the range of accidents that occurred in congested areas. It has also been noted that a higher incidence of crashes was linked to intoxication and speeding. The findings' impact resided in the peril to essential workers compelled to traverse the road system, while the capability of remote work was available to others. Potential future shocks to travel demand, and the possibility that traffic volumes might not return to prior levels, are considered, and recommendations are provided for policies that can reduce the chance of fatal or debilitating accidents among road users.

Researchers and practitioners in the field of transportation found both significant challenges and unprecedented opportunities arising from the COVID-19 pandemic. This article highlights key takeaways and knowledge gaps for transportation professionals, encompassing: (1) public health-transportation integration; (2) technological contact tracing and traveler tracking; (3) prioritizing vulnerable populations, including operators, patrons, and underserved communities; (4) adapting travel demand models for social distancing, quarantines, and public health measures; (5) challenges posed by big data and information technology; (6) fostering trust between the public, government, private sector, and other stakeholders in disaster management; (7) disaster-related conflict resolution; (8) the intricacies of transdisciplinary knowledge and collaboration; (9) the need for enhanced training and educational programs; and (10) transformative initiatives for community resilience. The lessons learned during the pandemic regarding transportation planning and community resilience should be communicated and customized for varied systems, services, modalities, and users' requirements. Despite a robust public health response to the pandemic, the complex management, response, recovery, adaptation, and transformation of transportation systems necessitate a multi-disciplinary, multi-jurisdictional approach that prioritizes communication, coordination, and resource allocation. More in-depth research is needed to effectively connect theoretical knowledge to practical applications.

Travel patterns and consumer desires have been profoundly altered by the COVID-19 pandemic. bacterial co-infections Public health officials, along with state and local governments, employed stay-at-home orders and supplementary actions, such as closing nonessential businesses and educational facilities, in their efforts to curtail the virus's spread. Metabolism agonist U.S. toll roads saw a notable year-over-year decrease in traffic and revenue, between 50% and 90% in April and May 2020, directly attributable to the recessionary impact. These disruptions have led to changes in the manner in which people travel, encompassing the types and frequency of their trips, the mode of transportation they choose, and their willingness to pay for time-saving travel options and reliable travel times. Research on travel behavior, conducted for the Virginia Department of Transportation within the National Capital Region (Washington, D.C., Maryland, and Northern Virginia), before and during the COVID-19 pandemic, is summarized in this paper. The research team employed a stated preference survey to determine travelers' willingness to pay for reduced travel time and reliable travel times, thereby assisting in projecting traffic and revenue for existing and proposed toll corridors. Albright’s hereditary osteodystrophy The survey's data collection efforts encompassed the timeframe from December 2019 to the end of June 2020. Comparing travel data collected before and during the pandemic highlights widespread changes in travel habits and a decrease in the willingness to pay for both faster and more reliable travel options, especially among drivers commuting to or from their jobs. These findings hold substantial implications for estimating future traffic and revenue projections, particularly regarding the return of travelers to toll corridors in the region.

The unforeseen disruptions of the 2020 COVID-19 pandemic drastically altered transportation systems, notably impacting subway ridership patterns within New York City (NYC), USA. Analyzing the temporal trajectory of subway ridership via statistical models is essential during periods of significant upheaval such as this. Nonetheless, the existing statistical frameworks available might not optimally suit the task of analyzing ridership data collected during the pandemic, due to potential violations of certain modeling assumptions. Utilizing change point detection techniques, this paper proposes a piecewise stationary time series model, enabling the capture of the non-stationary nature of subway ridership. The model's construction comprises numerous standalone ARIMA models, grounded in individual stations, which are interconnected at set moments in time. Data-driven algorithms are also applied to discern shifts in ridership trends, and to estimate the parameters of the model prior to and during the COVID-19 pandemic. The primary focus of the data sets is daily ridership at randomly chosen NYC subway stations. The proposed model's application to these datasets facilitates a more thorough understanding of ridership changes in the context of external shocks, including the average effects and their correlated time-dependent effects.

A framework for analyzing public dialogue on Twitter is proposed in this study to understand the influence of COVID-19 on transport methods and mobility habits. The sentence also specifies the impediments to reopening and likely reopening strategies that are a part of public discourse. Collected between May 15th and June 15th, 2020, this study analyzes 15776 tweets expressing personal viewpoints on transportation services. The subsequent stage involves the application of text mining and topic modeling techniques to the tweets, which serves to uncover the key topics, significant terms, and prevalent themes within the discussions, allowing for a deeper understanding of public perceptions, actions, and broad sentiments related to the changes in transportation systems resulting from COVID-19. Public transport usage is declining, with people opting instead for personal vehicles, bicycles, or walking, as evidenced by the findings. Although bicycle sales have increased substantially, car sales have unfortunately decreased. To combat the increased traffic congestion resulting from COVID-19 mobility disruptions, the exploration of solutions such as cycling, walking, telecommuting, and online schooling initiatives is being considered for the post-pandemic world. Public transport funding decisions were lauded by the populace, who concurrently advocated for the reconstruction, revitalization, and secure resumption of transit services. Ensuring the security of transit personnel, commuters, shop customers, and office staff is a foremost priority in the process of restarting operations; strategies including enforced mask usage, a gradual reopening, and the implementation of social distancing are proposed as potential solutions. Decision-makers can leverage this framework to grasp public perspectives on transportation during COVID-19, enabling the creation of safe reopening policies.
