ABSTRACT
The growing phenomenon of teleworking and the recent covid-19 pandemic have caused the volumes of pedestrians who routinely cross the city to change since March 2020. This change may have resulted in further damage to the health of pedestrians due to limited activity. Some recent studies point to slight changes in walking speed and stride length compared to changes in the number of steps, these changes were consistently seen during the state of emergency, they showed that people tried to walk faster in their outdoor walking. For the safety of pedestrians, it is necessary to analyse not only the change in speed when crossing but also the potential factors influencing it. These factors include user-related variables (gender, age, weight) and variables related to potential distractors such as smartphone use or walking in groups. The results of measurements made during the pandemic period (4 different phases) in pedestrian traffic in the zebra crossing area are also presented. The research was conducted in a zebra crossing area located in a small town in Sicily (Enna) frequently used by workers, students and elderly people. The results showed that during the first and second pandemic phases (May to October 2021) there were significant changes in the way of moving and the speed of pedestrians at crossings. The same crossings were also examined in the late autumn of 2021 (third and fourth pandemic phases) and the data show further changes in pedestrian behaviour. The data collected can help to improve safety in the area of pedestrian crossings through infrastructural actions or educational programmes and campaigns, especially among vulnerable groups of pedestrians.
ABSTRACT
Humanity has faced many pandemics throughout its history with COVID-19 pandemic being the most recent. Each pandemic requires the implementation of a series of restrictions and measures to reform local societies or even society on a global scale. Scientific and technological innovations have ensured the survival of mankind and consequently the establishment of new habits and trends. One of these reforms concerns the transport of goods and in particular urban logistics and last-mile delivery. Despite the increasing use of e-commerce, the average amount of money spent per month and per buyer has decreased;in times of uncertainty, people prefer to postpone big purchases and focus more on everyday products. These purchases have generated an increase in demand for the transport of goods and put significant pressure on the supply chain. For this reason, actions have been developed to improve logistics, in particular last-mile delivery, with the introduction of environmentally friendly and small vehicles, among others. In order to be able to trace the evolution of the combination of the COVID-19 pandemic and logistics spatially and temporally, the manuscript focused as a first step on the analysis of the literature entered in the main databases dedicated to scientific publications, returning some 2,227 indexed articles from 2000 to 2021. The search was conducted using keywords and iterations between them. The results emphasised the need to adapt business activities to the changing situation by anticipating people's needs, creating e-commerce sites capable of accompanying customers in this delicate phase. The results obtained were analysed from a statistical point of view, laying the foundations for future investigative steps in the field of last-mile logistics and the proper planning of loading and unloading spaces for goods in urban areas.
ABSTRACT
Gender equality is a fundamental human right and is part of one of the goals of the 2030 Agenda (Goal 5), which promotes a more equitable and sustainable way of life. A gender imbalance still exists in the transport sector. Over the years, the reasons why women travel have changed, as have their modal preferences, thanks to the introduction of concessions (pink parking, pregnant seats) but also thanks to the introduction of new forms of mobility and multi-modality. However, several works in the literature point out that women's journeys are in many cases more difficult than those of men because there are several factors that influence this imbalance. The recent COVID-19 pandemic has contributed to a widening this gap. Through the administration of an online questionnaire, it was possible to find data regarding socio-demographic characteristics, travel habits and finally to analyze the main problems and feelings (feeling of safety on board, perception of a possible contagion and overall evaluation of gender equity both as passengers and as drivers of vehicles) related to the different modes of transport present in the Sicilian context. A statistical comparison of the results was defined considering the different pandemic phases from January 2020 to December 2021. The results show the basis for a better mobility planning starting from the resolution of the COVID-19 crisis that represents an opportunity to change the status quo.
ABSTRACT
As humanity straggles to absorb the effects of the Covid-19 pandemic, city logistics is one of the transport sectors that has been affected. The restriction measures applied, and the regional lockdowns had put significant pressure on the supply chain but also on the last mile delivery. City logistics stand before a crossroad with important challenges lying ahead and difficult decisions to be made. The transformation of the city logistics sector is inevitable as more and more countries join an alliance against climate change. In this framework, the present paper presents an enquiry concerning the residents' acceptance at the city of Thessaloniki, Greece on the possible implementation of night deliveries. A questionnaire-based survey was conducted and the analysis of the collected data is presented revealing that the residents are aware of night deliveries' occurring problems as well as their willingness to accept the implementation of such policy if all necessary precautions and measures are applied.
ABSTRACT
The promotion of active transportation modes in urban areas is a key challenge towards the minimization of motor traffic externalities. After the COVID-19 outbreak, cities around the world started investing heavily in infrastructure for pedestrians and cyclists towards the enhancement of social distancing. However, infrastructure adequacy in the post COVID-19 era needs to be evaluated. Level of Service (LOS) as it is proposed by the Highway Capacity Manual (HCM) is the most common methodological tool to assess pedestrian facilities. Nonetheless, pedestrians' perceptions are more than needed especially in the post COVID-19 era. In this paper an online survey is conducted for the assessment of the main pedestrian facilities in the city of Thessaloniki, Greece. Respondents' sociodemographic characteristics, their social distancing perception as well as their travel habits after the COVID-19 outbreak are concerned. The main research goal is to reveal the most significant factors that affect pedestrians' perceived level of service (PLOS) using regression modeling. The results can shed light on respondents' perceptions about PLOS in the post COVID-19 era. Last, results can assist in policy making for the promotion of active transport modes in urban areas with respect to the current health recommendations for public spaces.
ABSTRACT
Since 2020, due to the Covid-19 pandemic, planners and designers have proposed numerous changes for urban spaces and mobility concepts to comply with governments' anti-contamination restrictions. Several European cities have implemented strategies for developing cycling, favouring the design of temporary (pop-up) or permanent cycle lanes and state incentives to purchase bicycles and electric micro-mobility vehicles. However, existing research suggests that design optimisation must pursue specific geometric, functional and safety standards for cyclists and space sharers (pedestrians/cars). It is thus necessary to analyse the perceptions of citizens and commuters for optimisation of the planning and design of these infrastructures. A multi-criteria evaluation was used to determine optimal infrastructure schemes (temporary and permanent) for the metropolis of Palermo in Sicily, Italy. First, three groups of cyclists (citizens, technicians and commuters) were selected. Then, applying the best-worst method, a series of design alternatives were evaluated by the target groups. The results showed a correlation between different types of users in terms of those who live in the city compared with commuters in the city for the first time. The results of this work lay the foundation for improved planning and design strategies in sustainable urban mobility plans and the Italian Biciplan guidelines.
ABSTRACT
The COVID-19 pandemic is a significant public health problem and the leading cause of reduction in the demand and supply of public transit in the last three years. It has caused an unprecedented reduction in the demand for public road transportation, and it has changed passengers' perceptions from positive to negative when it comes to using public transportation amenities. There is an increasing concern that the public road transportation systems are witnessing a new horizon, especially now that developed and developing countries are trying to resume their daily activities post COVID-19 pandemic. In this research, we focused on the overview of literature reviews of research within the past three years that focused on the challenges and solutions of the impact of the COVID-19 pandemic on public road transportation systems, especially when it comes to the enforcement of physical distancing in public transportation, usage of face masks and government interventions. The inclusion and exclusion criteria were used in reviewing the articles used for this literature review, and an original 140 articles were reduced to 100 articles that were used in this literature review. This research aims to create an overview literature review that highlights the impact of the pandemic on public transportation and identifies strategic ways in which urban planners and public road transportation researchers can develop constructive and efficient public road transportation planning to ensure the sustainability of public transportation systems in the post-COVID-19 era. This literature review extends our knowledge of the COVID-19 pandemic in public road transportation. It also provides additional evidence concerning the effectiveness of physical distancing and the use of face masks to prevent the COVID-19 virus in public road transportation networks.
ABSTRACT
As many studies have already shown, the COVID-19 pandemic has had a great impact on the daily routines of people all over the world. University students form one of the most affected groups of people, since they have had to interrupt many of the activities that they usually perform, and have also had to get used to a new way of learning (e-learning). An important question that now arises is whether the changes that were identified within the pandemic period are to be maintained when the risk of being infected is eliminated. To this end, 537 university students of the Kore University of Enna, Italy, were surveyed. Their responses are analyzed descriptively, and an ordinal regression model is being developed to shed more light on the likelihood of retaining changes related with to transport mode choice. The results show that the likelihood of retaining all the changes when commuting and during daily activities is very high, demonstrating such willingness from the participants. Moreover, it has been shown that public transport has increased the probability of people being negatively affected by the pandemic in the long-term, and opportunities appear for increasing the modal share of active modes.
ABSTRACT
The COVID-19 pandemic has significantly influenced people’s lifestyles including their travel choices. The pandemic resulted in placing restrictions in travelling throughout Italy due to the obligatory need for social distancing and changes in public transport services. City residents changed their mobility patterns and started using their private vehicles more often instead of public transport, while choosing to walk or cycle for short distance trips. Governments and local authorities encouraged citizens to use sustainable travel modes, particularly walking, during the pandemic period. However, the high number of infections and deaths, especially in Italy, has strongly influenced the propensity of walking due to the emotional aspects of travelling. This paper presents a statistical analysis based on data gathered through a questionnaire in urban areas of Sicily focusing on travel by walking for either leisure or work. The evaluation of negative emotions that people who habitually walk for short distances in the study areas is the main focus of the present work.The data indicated a variation between three emotions: anxiety, stress, and fear. These emotions had a potential to influence people’s daily life and, as a result, their travel habits.
ABSTRACT
Mobility since 2000 has undergone enormous changes due to new modes of transport and related technologies as well as catastrophic and pandemic events. Several strategies have been implemented by European states to mitigate impacts and assess possible risks in a preventive way. Today, mobility pursues the objectives of sustainability and resilience through a series of short-, medium- and long-term strategies that encourage the collaboration of the population to the choices of urban planning and design. Among the different modes of transport that have had a rise in recent years are scooters. Such modes are well suited to connecting spaces within the first and last mile. Similar to other modes of transportation, scooters are also characterized to date by reduced gender equity. The present work investigates through the administration of an online survey the participants’ perceptions concerning the factors that most affect this gender balance considering the metropolitan areas of Catania and Palermo in Sicily. The development of an ordinal regression model revealed the most influential factors of the gender equality variable. Specifically, age, job occupation and perceived safety level of micromobility modes play the most important role. The present findings can be effectively utilized in the planning stage of e-scooter services towards the bridging of the gender gap.
ABSTRACT
The most important protective measure in the pandemic process is a vaccine. The logistics and administration of the vaccine are as important as its production. The increasing diffusion of electronic devices containing geo-referenced information generates a large production of spatial data that are essential for risk management and impact mitigation, especially in the case of disasters and pandemics. Given that vaccines will be administered to the majority of people, it is inevitable to establish vaccination centres outside hospitals. Site selection of vaccination centres is a major challenge for the health sector in metropolitan cities due to the dense population and high number of daily cases. A poor site selection process can cause many problems for the health sector, workforce, health workers, and patients. To overcome this, a three-step solution approach is proposed: (i) determining eight criteria using from the experience of the advisory committee, (ii) calculating criterion weights using Analytic Hierarchy Process (AHP), and performing spatial analysis of criteria using Geographic Information System (GIS), (iii) assigning potential vaccination centres by obtaining a suitability map and determining service areas. A case study is performed for Bağcılar, Istanbul district, using the proposed methodology. The results show that the suitable areas are grouped in three different areas of the district. The proposed methodology provides an opportunity to execute a scientific and strategic vaccination programme and to create a map of suitable vaccination centres for the countries.
ABSTRACT
As in other countries of the world, the Turkish government is implementing many preventive partial and total lockdown practices against the virus’s infectious effect. When the first virus case has been detected, the public authorities have taken some restriction to reduce people and traffic mobility, which has also turned into some positive affect in air quality. To this end, the paper aims to examine how this pandemic affects traffic mobility and air quality in Istanbul. The pandemic does not only have a human health impact. This study also investigates the social and environmental effects. In our analysis, we observe, visualize, compare and discuss the impact of the post- and pre-lockdown on Istanbul’s traffic mobility and air quality. To do so, a geographic information system (GIS)-based approach is proposed. Various spatial analyses are performed in GIS with the statistical data used;thus, the environmental effects of the pandemic can be better observed. We test the hypothesis that this has reduced traffic mobility and improved air quality using traffic density cluster set and air monitoring stations (five air pollutant parameters) data for five months. The results shows that there are positive changes in terms of both traffic mobility and air quality, especially in April–May. PM10, SO2, CO, NO2 and NOx parameter values improved by 21.21%, 16.55%, 18.82%, 28.62% and 39.99%, respectively. In addition, there was a 7% increase in the average traffic speed. In order for the changes to be permanent, it is recommended to integrate e-mobility and sharing systems into the current transportation network.
ABSTRACT
A sharp decline in public transport use has been reported worldwide since the outbreak of the COVID-19 pandemic. As the virus spreads through close contacts, particularly in closed environments, public transport vehicles could be considered as hotspots for its transmission. However, public transport operations cannot be entirely stopped as many people in developing countries rely on them for their travel needs. This study aims to provide insights into people's travel mode choices during the COVID-19 pandemic. Data, i.e., 1,516 complete survey responses, were obtained through a questionnaire that was conducted in Lahore, Pakistan. A binary logistic model was developed using the collected data to model the likelihood of choosing solo or public transport modes during COVID-19. The results explained that the respondents preferred solo modes more than the public transport modes during the pandemic. Gender, income, education, profession, trip frequency, car ownership, motorbike ownership, and an underlying factor that was defined as “safety precautions” were found to be significant predictors of the public transport choice relative to solo modes. Females tend to choose public transport modes relative to solo modes as compared to males. Private vehicle (car or motorbike) owners were less likely to use public modes relative to solo modes when compared to those who do not own private vehicles. The outcomes of this study could be important for the government authorities, policymakers and transport operators to understand the public transport use in developing countries during pandemics. Such information will be useful to devise regulations and preventive measures to control infectious diseases associated with public transport use, particularly in developing countries, where private transport options are limited.
ABSTRACT
Public transport use has drastically declined during the COVID-19 pandemic because the virus spreads through close contact with infected people and contaminated surfaces, especially in closed-environments. Evidence suggests that following the necessary safety guidelines can limit the spread of the virus, however, non-compliance to precautionary measures has been reported widely. Ignoring the precautionary measures may lead to quick transmission of the virus since public transport vehicles generally resemble closed-environments. This study explores people’s intentions to use public transport during the COVID-19 pandemic while adhering to precautionary measures. For this purpose, a total of 1516 useable responses were collected through a questionnaire survey conducted in Lahore, Pakistan. Regression models were developed to model the intentions to use public transport during the pandemic, to adhere to the precautionary measures while using public transport during the pandemic, and to use public transport while suffering from COVID-19 disease. The results of this study will help in understanding the intentions of the public transport users during the COVID-19 pandemic. It will also provide insights for policymakers and public transport operators about further necessary actions to promote safe public transport use during the current and any possible future pandemics. As public transport use declined during the pandemic, policy implications for alternative mobility options such as demand-responsive-transport (DRT) are also presented. Considering the study results, a policy interventions framework is proposed to promote the safe use of various public transport modes, particularly in developing regions.
ABSTRACT
Transport planning and public health have been intertwined historically. The health impact of public transport services, such as social exclusion, is a widely discussed research topic. Social exclusion is a paramount concern for older adults' health in the wake of emerging global challenges. However, there remains a significant research gap on how psychosocial barriers faced by older adults in using public transport services influence the social exclusion behavior. The present research provides empirical evidence and shows the impact of certain psychosocial barriers of public transportation on older adults' social exclusion. A total of 243 Pakistani older adults (aged 60-89 years old) voluntarily participated in this cross-sectional study. The participants provided self-reports on their psychosocial barriers (including perceived norms, attitude, personal ability, habits, neighborhood social constraints, and intention) and the corresponding social exclusion. Partial Least Square Structural Equation Modeling (PLS-SEM) was utilized for the data analysis. The structural path model supported the significant associations between psychosocial barriers and social exclusion. Except for perceived descriptive norms, all other psychosocial barriers predicted older adults' social exclusion. The research portrays the significance of the psychosocial factors to examine social exclusion and offers practical implications for urban and transport planners. The concerned policymakers can use the research findings to develop age-sensitive, socially sustainable, and healthy cities.

The COVID-19 pandemic has resulted in unprecedented measures changing travel habits in many countries. Many users have started to prefer traveling by private cars, which is against the sustainability policies of the European cities. The necessity of gaining a deeper understanding of road users’travel habit changes, their feelings on public transport use, and their perceptions of using sustainable urban mobility modes has emerged for future transport planning. Considering these facts, the study in this paper aimed to investigate the influence of the COVID-19 pandemic on road users’perceptions, needs, and use of sustainable travel modes (i.e., public transport, walking, and cycling). An online survey was carried out during the period from March to May 2020 in the case study area, Sicily of Southern Italy. Regarding the population of the case study, the survey was representative, with 431 individuals. The survey included variables, namely gender, age, city of residence, private car ownership, walking and cycling frequency before and during the pandemic, public transport use frequency for leisure activities before and during the pandemic, need for remote working, and the stress and anxiety perception of using public transport during the pandemic. The analysis started with descriptive statistics and it was followed by correlation analysis in order to explore the characteristics of the dataset and relationship between variables. It was found that these were not statistically significantly correlated at a 95% confidence level. An ordinal regression model was applied for determining the predictions. The results suggested that women were less likely to walk during the pandemic than men. Participants were more likely to resume remote work even after the second phase in order to reduce their daily travel needs and keep their isolation. Participants have expressed a positive opinion on the use of micromobility during pandemic situations. These results can be considered as a basis for sustainable urban planning and a guide for decision-makers who aim to encourage the use of public transport, walking, cycling, and micromobility.
ABSTRACT
This paper investigates the problems and stresses of the contemporary city, mainly due to natural and health factors, related to climate change and the pandemic COVID19. Besides highlighting the characteristics of climate change and the ongoing pandemic, this study focuses on the analysis of the main effects and consequences that these phenomena have produced on the city and the vulnerabilities of the urban system. To understand how these events have impacted the urban environment, directly and indirectly, this research undertakes to define some specific indicators capable of comparing the phenomena and assessing their repercussions. The Methodology is based on the following focal points: on the analysis of the urban shocks that have affected the cities in the last decade, on the comparison between contemporary survey data and those relating to historical trends, on the definition of the main urban sectors particularly affected by the onset of urban shocks, and on the definition of strategies, actions, and tools deemed to be effective in the implementation of a post-pandemic and climate-proof city. These results were achieved through complementary urban design and tools capable of creating a post-pandemic and climate-proof adaptive city, within a cross-disciplinary approach.
ABSTRACT
Interest towards urban micromobility has been growing lately, and it will now increase further due to the measures used against COVID-19. It is recommended to avoid close contact to prevent contagion. Municipalities have been called to implement wider cycling networks so that people may go to their work place by cycling rather than by using public transport. This paper focused on cycling path design using an infrastructure-building information model (I-BIM). The issue covered was how to connect cost and safety requirements in the first steps of the project. We set a methodology that gives, after identifying the intervention area and defining the available economic resources, the key elements needed to design possible cycle path solutions. It guides the designer step-by-step, starting from basic assumptions related to a cycle path’s location (urban/non-urban), budget (by range), and safety (according to Bicycle Compatibility Index BCI and Bicycle Level of Service (BLOS) index), up to the definition of preferred options in terms of materials to be selected. As a case study, we implemented this methodology in the old city center of Catania in Sicily (Italy), designing a cycle path that connects the city center with the existing cycle path on the coast, while aligning with safety requirements within budget constraints.
ABSTRACT
All countries have suffered from the COVID-19 crisis;the pandemic has adversely impacted all sectors. In this study, we examine the transport sector with a specific focus on the problem of commuting mode choice and propose a new decision-making approach for the alternative modes after synthesizing expert opinions. As a methodology, a customized model of the recently developed best–worst method (BWM) is used to evaluate mobility choice alternatives. The survey reflects citizens’ opinions toward mobility choices in two Italian cities, Palermo and Catania, before and during the pandemic. BWM is a useful tool for examining mobility choice in big cities. The adopted model is easy to apply and capable of providing effective solutions for sustainable mode choice. The urban context is analyzed considering the importance of transport choices, evaluating the variation of resilience to the changing opinions of users.
