Most safety concerns for pedestrian trips arise during road crossing, due to the interaction of pedestrians with motorized vehicles. This present paper attempts to explore the factors that have significant impact on pedestrians’ crossing behavior, and to identify the group of pedestrians that appear to be the most prone to crossing a road during the first five seconds of the red phase. In this context, observations were conducted in twelve signalized crossings in one-way roads, in the city of Thessaloniki, Greece. The collected data (600 observations of crossing pedestrians) were analyzed statistically; more specifically, the observations were analyzed through descriptive statistics, and a classification tree was developed for predicting pedestrians’ decisions. The results indicate that pedestrians’ crossing behavior is most of all affected by the behavior of other pedestrians in the signalized crossing. Also, the number of traffic lanes has an impact on pedestrians’ decision to cross the road during the first five seconds of the red-light phase.

Intersection safety and drivers’ behavior are strongly interrelated, especially when the latter are located in dilemma zone. This paper explores, among others, the main factors affecting driver behavior, such as distance to stop line, approaching speed and acceleration/deceleration, and two additional factors, namely, driver’s aggressiveness and driver’s relative position at the onset of the yellow signal. Field data were collected using unmanned aerial vehicle (UAV) technology. Two binary choice models were developed, the first relying on observed data and the latter enriched by the latent factor drivers’ aggressiveness and the vehicles’ relative position. Drivers were classified to aggressive and non-aggressive ones using a latent class model that combined approaching speed and acceleration/deceleration data. Drivers were further grouped according to their expected reaction/decision to stop or cross the intersection in relation to their relative position. Both models equally explain drivers’ decisions adequately, but the second one offers additional explanatory power attributed to aggressiveness. Being able to identify the level of aggressiveness among the drivers enables the calculation of the probability that drivers will cross the intersection even if caught in a dilemma zone or in a zone in which the obvious decision is to stop. Such findings can be valuable when designing a signalized intersection and the traffic time settings, as well as the posted speed limit.

Pedestrians–cyclists shared spaces, sidewalks and streets are now a commonly implemented urban design solution in many cities, due to the willingness to promote sustainable mobility and the non-availability of public space. The proper design and management of these infrastructures requires an accurate evaluation of their performance. The most dominant evaluation metric is the level of service (LOS) and various methodologies have been proposed in the literature for its assessment in infrastructures that are being used by pedestrians, cyclists or by both of these two types of users. The present paper gathers and presents various methodologies, and it applies some of them on two pedestrians-cyclists shared spaces in a medium-sized city in Greece. The outcomes of the methodologies are being compared both among themselves and in relation to the opinions of the users, who participated in a questionnaire survey. The review of the literature, along with the application of some of the methodologies, leads to a fruitful discussion, which sets the groundwork for future research in the field of LOS and it also assists practitioners in selecting the appropriate methodologies for the assessment of pedestrian–cyclists shared spaces.

Electronic toll collection (ETC) plays, as part of transport demand management (TDM) measures, an important role in preventing traffic congestion and improving the environmental conditions in urban and rural areas. An attempt is made in the framework of this paper to evaluate the overall performance of a toll station when a lane is dedicated to ETC. The case study refers to a toll station in the Thessaloniki Metropolitan Area, Greece. Scenarios considered specific traffic characteristics, variable toll booth setups, and different penetration rates of the ETC tag users for car and heavy vehicles. The tool used in the evaluation process was the PTV Vissim traffic simulation software. The operation of the toll station during a specific peak-hour period was simulated with the aid of the specific software. In total, 39 alternative scenarios were developed and compared to determine the level of penetration rate for which the ETC lane would be effective for different toll booth setups. Results showed that when the right lane of the toll station is converted to ETC lane, the penetration rate of this lane must be greater the 15% for the private vehicles and 20% for the heavy goods vehicles (HGV) to reduce traffic congestion and to improve environmental conditions. It was also found that when an additional ETC lane was introduced to the existing toll station set up, traffic congestion and the associated environmental conditions were much improved even for low penetration rates. It must be noticed that the results from the use of discounted cash flow methods like internal rate of return (IRR), net present value (NPV) and benefit–cost ratio (BCR) showed that all economic indicators converge as penetration rate increases in all toll booth setups. Therefore, there is a specific penetration rate threshold above which the economic viability of the investment is secured. These findings can assist the design of an effective policy in terms of the optimized operation of a toll station and sustainable mobility planning.

Current mobility strategies tend to pursue sustainable solutions with low environmental and economic impact, such as the disincentive to the use of private vehicles. Mobility on foot is among the most advantageous forms for short distances, especially if different technological and infrastructural solutions are inserted in the urban context such as underpasses that limit the likely conflicts with motor vehicles. These solutions, however, are not easily perceived as positive because people often do not like to change their usual routes or because they feel psychological discomfort when they pass through closed places. This research work focuses on the evaluation of the benefits of including a small underpass in the city of Rijeka, Croatia and through an Analytical Hierarchy Process (AHP), a multi-criteria analysis, it was possible to prioritize a number of decision-making alternatives, related to qualitative and quantitative evaluations, otherwise not directly comparable, and combining multidimensional measurement scales into a single priority scale. This analysis allows to provide cues for local and non-local urban planning, encouraging through the participatory form an active comparison between the population and local authorities and at the same time allows to assess which multidisciplinary processes (psychological/engineering) are possible to put in place to encourage the research on pedestrian behavior.

Connected and autonomous mobility are of great interest in transport research. Furthermore, Rail-Road Level Crossings represent high-risk locations of the network and the accidents that take place at them are considered as one of the most significant accident categories that occur at rail infrastructure. Hence, the evaluation of cooperative systems with the aim of increasing safety at Rail-Road Level Crossings is a crucial issue especially towards the evaluation of the system’ objectives as well as decision making for investments regarding in-vehicle warning systems. However, there are many barriers regarding the ex-post evaluation of these systems such as difficulty in collecting and analyzing quantitative data as well as GPS low accuracy. The present research examines the ex-post evaluation of an in-vehicle warning system for Rail-Road Level Crossings developed within the Horizon 2020 project “SAFER-LC” and tested in the city of Thessaloniki, Greece. The evaluation made with a questionnaire-based survey which was carried out in August-October 2019. Statistical analysis revealed numerous interesting findings between drivers’ socioeconomic attributes and the way they assess the in-vehicle warning system, indicating the high level of acceptance towards the tested driver assistance system, by a demanding professional drivers’ group.

Road safety plays an important role in cities as far as sustainability and resilience are concerned. A large number of studies focus on the evaluation of the safety level of road users and especially vulnerable road users. In the framework of this paper an analysis was carried out concerning one of the most important problems at signalized intersections, which are the RLR (Red Light Running) and the YLR (Yellow Light Running) violations. This problem has to do with the behaviour and attitude of drivers as far as their compliance with Highway Code regulations is concerned. The existing situation in relation to RLR/YLR violations was investigated in the city of Thessaloniki, Greece and in Sicily, Italy. Field counts took place in each area followed by data analysis. Two sets of counts (Sicily and Thessaloniki) were used in the framework of this paper in order to investigate the above-mentioned phenomenon. Finally, a comparison between the results concerning both areas was made together with an attempt to investigate through inferential statistics the extent to which both the traffic volume and the category of vehicles affect RLR/YLR. The results can be used as a basis in order to calibrate behavioural models.

The operation of minibuses as public transport modes worldwide is considered as a both efficient and effective way to meet the mobility needs of special population groups in urban areas. Minibus services are more flexible in terms of routing and scheduling as well as more affordable compared to regular bus public transport. This paper investigates the potential introduction and the characteristics of a minibus transit service in the Municipality of Kalamaria (~90,000 pop.) in Thessaloniki Greater Area, Greece. The research is based on a joint revealed and stated preference survey, which took place in 2015 and was addressed to the citizens of the Municipality, where such a minibus service was formerly active. The revealed preference survey mainly explored the current travel behavior of citizens and their level of acceptance for such a service in case of its reopening. The stated preference survey investigated the intentions and travel preferences of the respondents under different scenarios of travel time, service frequency and travel cost. A total of 140 questionnaires was collected and analyzed using descriptive and inferential statistics. Causal analysis was conducted to reveal interrelations of respondents’ willingness to use the service depending on the above attributes. According to the research findings, the perceived “quality of service” is strongly associated with safety, reliability and comfort of the transport mode used. Additionally, travel time is considered more important than cost. Although respondents seem to prefer a free of charge service, it was found that Willingness-to-Pay for minibus services ranges around 0.5 euros.

Micromobility aims to provide environmentally friendly options for trips that cannot be accomplished with public transport and reduce automobile dependence. The most recent transport mode for accomplishing such trips is the electric scooter (e-scooter) and they have flooded several countries and cities taking a significant share of trips. However, there is little guidance regarding their operations and initial observations demonstrate public disdain. This article deals with the evaluation of the public opinion in regard to e-scooters based on those who do not use them. To solicit input, an in-person and an electronic questionnaire were used in Thessaloniki, Greece. Statistical analysis of the collected data was undertaken to establish possible pattern of public opinion and identify situations of e-scooters that cause problems in pedestrian and motor vehicle traffic. Furthermore, the lack of infrastructure, which is a deterrent to e-scooter use, and the absence of a legislative framework that sets out the rules for traffic seem to be main concerns. Finally, the surveys noted that e-scooters will be promoted and integrated into traffic by designing and building adequate infrastructure, training users in Highway Code and imposing fines on offenders.

Micromobility, defined as short-distance transport, is recently experiencing a global growth. The primary goal of this new mobility trend is to provide environmentally friendly options for trips that cannot be accomplished with public transport and reduce automobile dependence. A popular transport mode is electric scooters (e-scooters) and they have been making inroads in several countries and cities on a global scale. However, there is little guidance regarding their operations. The purpose of this research is to evaluate the users’ attitudes and behavior of e-scooters in Thessaloniki, Greece. In-person and electronic surveys were completed targeting persons who have used an e-scooter more than once. The findings indicate that users most frequently ride on bicycle lanes and on roads without bike lane, while they prefer to use them for recreational purposes and not for commuting. Concerning the issues that would prevent them from using an e-scooter, greater importance is assigned to the bad behavior of car drivers, while bicycle lanes is considered the most efficient way for improving the use of e-scooters. Finally, slight differences were found on the behavior of users based on their age and gender, but people of different age and gender share similar attitudes.

Recently, the share of bicycles among transportation modes has been rising. This is also the case in university campuses that have seen an increase of bicycling as a transport mode. Transportation authorities globally encourage bicycling as a way for pollution reduction and alleviation of traffic congestion. However, lack of bicycle facilities could significantly hinder increase in bicycling levels. This study used in-person surveys to evaluate the attitudes and desires of bicyclists in two university campuses in Greece: Thessaloniki and Volos. The goal of the survey was to identify barriers to bicycling in both cities and pinpoint facility aspects that could be improved. Descriptive statistics and hypothesis testing were utilized in the analysis of the survey data to determine the level of agreement among participant responses and document their attitudes and preferences. Lack of bicycling facilities was the main impediment that respondents in both cities identified: a finding that agrees with prior research. In addition, the aggressive behavior of car drivers is considered an important obstacle in both cities. The survey findings support to the notion that bicyclists everywhere have similar attitudes about what the types of improvements required for increasing bicycling and enhancing their experiences. In addition, local conditions and practices have an impact on the relevance of specific issues.

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.

In recent years, many efforts are being made for the promotion of active modes of transport. Due to this reason, as well as due to the limited available public space, the co-existence of pedestrians and cyclists is a very common phenomenon, which requires extensive investigation. The design and implementation of pedestrians-cyclists shared use space is a widely used technical choice, when the road infrastructure is unsuitable for hosting cyclists and thus the separation of cyclists from the motorized traffic is considered advisable. However, the co-existence of pedestrians and cyclists is not always harmonious and the interactions between them can have a negative impact in their perceived comfort and safety. The present research aims to quantify this negative impact of the various kinds of interactions, by considering the users’ attitudes and by applying the Analytical Hierarchy Process method. The attitudes of users were captured through questionnaire surveys, that were directed to both pedestrians and cyclists in the city of Palermo, Italy. The results of the analysis are being compared with the results of a previous attempt to quantify the impact of interactions. Through this comparison, useful conclusions and notes for further research are deriving.

Mobility is one of the most important and challenging aspects that influence climate change, air quality, and especially the quality of citizens’ lives. Therefore, creating sustainable transport solutions makes way for different modes of transport such as the bicycle, which is continuously gaining more supporters, due to the health, economic, and environmental benefits that it provides. However, cyclists are facing several barriers (e.g., lack of infrastructure), a fact that keeps away commuters from using a bicycle for their daily trips. Investigating the factors that reflect on the commuters’ intention to use a bicycle is a sine qua non for the promotion of sustainable mobility. Therefore, the objective of this paper is the investigation of the factors that prevent residents with low experience or with no cultural/lifestyle background in regards to cycling from cycling. The case study of the city of Larnaca (Cyprus) is deployed by exploring the socio-demographic and trip characteristics of the city’s residents and their relation with the intention to cycle. A two-step approach is developed, namely Explanatory Factor Analysis (EFA) and Structural Equation Modeling (SEM). Despite the promotion of cycling that education is attempting to do (successfully), other factors (such as age, distance, and time) appear to prevent Larnaca’s residents from cycling. Among the actions that local authorities should undertake is that of safety prevention of the vulnerable users of the road network. This group includes elderly people, who need major encouraging interventions by local policymakers and stakeholders.

The present research has investigated the impact of a Cooperative – Intelligent Transport Systems service for increasing Rail – Road Level Crossing safety, in terms of driving dynamic of the taxi drivers who used the service at the city of Thessaloniki, Greece. The Cooperative – Intelligent Transport Systems service informed drivers when approaching a Rail – Road Level Crossing, through 6 different paths, at the western area of the city of Thessaloniki. The results were yielded after comparing two datasets concerning the use of the Cooperative – Intelligent Transport Systems service by 168 taxi drivers for 28 days and without the use of the Cooperative – Intelligent Transport Systems service by 15 taxi drivers for 25 days. Even if conclusions are contrasting for the different types of the Rail – Road Level Crossing transits, the findings highlight a relation between speed reduction with types of transits whose first road segment is rectilinear, during Cooperative – Intelligent Transport Systems service use, while minor differentiations are noticed for Rail – Road Level Crossing transits with sharp turns and stop signs.

The limited available public space and the intention to promote active mobility, enhance the importance and the interest about pedestrians-cyclists shared spaces. This paper proposes a new methodology for determining the level of service (LOS) in shared spaces, based on the hindrance concept. In this context: a) the types of events between the users were identified, b) regression tree models for predicting the events’ frequency were developed, c) weights were assigned to the various events, based on their negative impact on users’ perceived comfort and safety. The assignment of weights consists a novelty of the proposed methodology since there is no other study attempting to identify their negative impact. Eventually, a mathematical formula suitable for optimizing the design and management of pedestrians-cyclists shared spaces, by minimizing users’ hindrance, is being produced. The objective of the methodology is to be a reliable and easy to use tool for planners and decision-makers. From the application of the methodology in the city of Thessaloniki, Greece, it is identified that: a) the pedestrian and bicycle flow rates play a decisive role in the frequency of experiencing events, b) “delayed passing” is the most disturbing situation for both pedestrians and cyclists, c) “passings” have similar negative impact on users’ perceptions with “meetings”.

Transport policy objectives, as well as lack of space in the built environment make clear that the coexistence of pedestrians and cyclists is an important issue. For that reason, a survey was conducted on two sidewalks and one pedestrian street in the city of Thessaloniki, Greece where the cycling volumes and cycling experience are still low; however efforts are being made to promote active transport modes (e.g. cycling, walking). In the analysis made in this paper, an ordinal regression model was developed that utilizes questionnaire survey data and field measurements. The aim of the ordinal regression model is to identify and quantify the impact of geometric, functional and social factors on pedestrians' perception about the presence of bicycles and the infrastructure level of service (LOS). The results show a clear difference in the perceptions according to gender and age. Females tend to perceive lower LOS and the same applies for the younger people. Regarding the geometric and functional attributes, pedestrian unit flow rate has been found to affect perceived LOS to a large extent. Another conclusion that emerges from the analysis is the importance of a proper distribution of the available space between pedestrians and cyclists, as over-dimensioning of the bicycle lane has a significant impact on the perceptions of pedestrians, regardless the bicycle volumes.

In recent years, the relationship between transportation and subjective well-being has been a major subject. Well-being is a factor that can affect travelers’ psychology and transport mode choice. For this reason, policymakers have attempted to improve travelers’ subjective well-being and promote sustainable modes of transport. For a better understanding of these factors, a questionnaire-based survey was conducted to identify the travel eudaimonia aspect of subjective well-being (comfort, safety, autonomy, self-confidence, physical, and mental health), for the various means of transport in the city of Thessaloniki. During the survey, 300 valid questionnaires were completed. The collection of the above data was followed by statistical analysis. The aim of the analysis was to identify the factors of travel eudaimonia that contributed to the mode choice. For that reason, four ordinal regression models were developed to determine how travel eudaimonia affected the usage frequency of the four available means of transport in the city of Thessaloniki (i.e., private car, bicycle, public transport, walking). Walking was rated higher than other modes in all factors, whilst cycling was rated high in physical and mental health, self-confidence, and autonomy, but low in comfort and safety. Public transport scored very low in all factors, demonstrating the poor quality of service provided by the city’s public transport. Moreover, from the ordinal regression models’ results, it could be demonstrated that travel eudaimonia factors had a significant role to play in mode choice. Recognizing the impact of these factors on transport mode choice is particularly useful for policymakers, researchers, and engineers, as it helps them to make informed decisions about what improvements are needed to promote sustainable modes of transport (mainly walking, cycling, and secondarily, public transport).

Transport is widely considered as a sector with significant positive and negative externalities affecting society, environment and economy. The fact of incorporating the main principles of sustainable development into transport planning is of prime importance. However, moving towards transport sustainability is a challenging task; it requires a paradigm shift as well as the constant monitoring and intensive evaluation of the current conditions through broadly accepted methodological tools such as indicators. In this context, the scope of the current research is to provide a complete picture of the approaches which aim at measuring progress towards transport sustainability as well as facilitating the development of new initiatives by highlighting the major trends. Consequently, a considerable number (78) of sustainable transport indicator initiatives were selected through an extensive literature review. Accordingly, descriptive statistics was used regarding the main features of the examined initiatives, while an analysis focused on the 2644 included indicators was subsequently implemented. The current research illustrates the linkages among the sustainability pillars and the selected objectives/themes. It also points out the great variability regarding the hierarchical structure, categorizes the considerable number of themes found in the literature into smaller groups, presents the most commonly used themes and indicators, and finally proposes an alternative categorization of weighting schemes concerning indexes. An attempt has been made so that this study can become a meaningful operational tool for researchers aiming at promoting the relevant research by contributing to the selection of the most suitable yet compatible and scientifically valid methods for each case.

Worldwide, pedestrians make up close to half of all motor-vehicle related fatalities but disproportionally little of the research in Information Technologies (IT) in general and Intelligent Transportation Systems (ITS) in particular has aimed at pedestrian safety improvements. This paper analyses and compiles three different ways so that IT and ITS can be used in order to improve mobility and safety of pedestrians in urban spaces: (a) for contacting and/or being localized, (b) for guidance (leading/navigating), (c) for alerting or informing of a danger. The aim is to categorize recent experiences where ITS can improve pedestrians’ mobility and safety so that new ideas based on ITS will be developed. These new ideas will better meet pedestrians’ functional quality needs today as well as in the future in a society with an aging population and aging infrastructure. This is very important for a society where people will not accept high fatality risks. The most important developments are described with links to websites in which one can gather more information. Target groups of this paper are professionals working in the field of traffic planning; practitioners, planners and researchers.
