The recent pandemic has considerably changed urban transportation while highlighting the weaknesses of the current transport modes. The crisis provided a unique opportunity to redesign the urban mobility plans in a more sustainable and resilient way. This study captured the impact of the COVID-19 outbreak and the subsequent restrictive measures on citizens’ commuting habits and travel mode choice in two Cretan cities with academic communities and intense seasonality of tourism, in two phases (four periods) before, during, and after the quarantine. The sample consisted of 308 (1st phase) and 193 (2nd phase) citizens, 60% and 30% permanent residents of Chania and Rethymno, respectively. During the weeks before the pandemic, 4/10 participants opted for travelling by car daily, either as a driver or as a passenger; almost the same ratio chose walking; 1/10 used public transport (bus). During the first week of the quarantine, one-quarter had decreased car usage and opted for sustainable transport modes (walking, cycling, public transport). The population who chose walking 1–2 times weekly almost doubled. Nevertheless, most factors were found to affect men and women differently; personal safety and road safety are significantly more important for women; ecological footprint is a less essential parameter for men’s travel mode choice. Private vehicle use still holds a considerable role in urban transportation, and noteworthy is due to the sharp decline in public transit in January–February and April and the meager percentage of public transport ridership (1%). The analysis and modelling could be useful in the future design of more sustainable and resilient mobility strategies.

In several European rural communities, woody biomass is considered amongst the most important energy sources for heating and cooking. However, the use of old-fashioned replaces may affect indoor and outdoor air quality. To depict this situation and to plan the necessary improvement interventions, a pilot action was implemented in a typical mountainous Mediterranean area (town of Anogeia, Crete). The action involved: (i) identi cation of the quantities, use and source of the woody biomass used in the community based on the analysis of data collected through a systematic survey; (ii) on-site indoor and outdoor measurements of air quality (CO 2 , CO, NO X , PM), during wintertime and summertime. Based on the current survey, around 70% of the study area households in Anogeia using woody biomass for heating purposes in low energy e ciency systems resulted in high annual consumption of rewood.Fifty-three per cent of occupants didn't consider indoor air quality as a result of wood burning. The analysis of the air quality showed very high concentrations of indoor air pollutants in the majority of old buildings with seniors using traditional heating systems. The type of main/supplementary heating system used in a dwelling depends on factors such as the size of the dwelling, year of construction, education level and age of occupants. The results also demonstrate a strong correlation/liaison between the heating season (summertime/wintertime), and the (signi cant increase in the) concentrations of air pollutants in the sampling sites.

By exploiting the opinion of the society in a Mediterranean city, this paper identifies the mechanisms behind utility cycling and determines the aspects of using the bike in cities for daily commuting. This study focused on the assessment of biking as an alternative mode of transport within a typical Mediterranean city in Crete. Limited road safety is the principal reason that hinders 60% of respondents from cycling, and 41% from riding more frequently. The survey results are congruent with this statement, provided a significant difference in the ratios of actual recreational cyclists (39%) and those who like to ride for entertainment, but they hesitate (71%). In order to quantify this, the attitude of the bikers was grouped in two fact factors influencing: the clothing and the technological one. Based on the opinion of the local society, high priority policies are recommended, such as proper infrastructure, sensitization campaigns, and education programs.

In several European rural communities, woody biomass is considered amongst the most important energy sources for heating and cooking. However, the use of old-fashioned fireplaces may affect indoor and outdoor air quality. To depict this situation and to plan the necessary improvement interventions, a pilot action was implemented in a typical mountainous Mediterranean area (town of Anogeia, Crete). The action involved: (i) identification of the quantities, use and source of the woody biomass used in the community based on the analysis of data collected through a systematic survey; (ii) on-site indoor and outdoor measurements of air quality (CO2, CO, NOX, PM), during wintertime and summertime. Based on the current survey, around 70% of the study area households in Anogeia using woody biomass for heating purposes in low energy efficiency systems resulted in high annual consumption of firewood. Fifty-three per cent of occupants didn’t consider indoor air quality as a result of wood burning. The analysis of the air quality showed very high concentrations of indoor air pollutants in the majority of old buildings with seniors using traditional heating systems. The type of main/supplementary heating system used in a dwelling depends on factors such as the size of the dwelling, year of construction, education level and age of occupants. The results also demonstrate a strong correlation/liaison between the heating season (summertime/wintertime), and the (significant increase in the) concentrations of air pollutants in the sampling sites.
