The Impact

Mobility as a Service (MaaS) is an emerging concept that is being advanced as an effective approach to improve the sustainability of mobility, especially in densely populated urban areas. MaaS can be defined as the integration of various transport modes into a single service, accessible on demand, via a seamless digital planning and payment application. Recent studies have shown the potential reduction in the size of automobile fleets, with corresponding predicted improvements in congestion and environmental impact, that might be realized by the advent of automated vehicles as part of future MaaS systems. However, the limiting assumptions made by these studies point to the difficult challenge of predicting how the complex interactions of user demographics and mode choice, vehicle automation, and governance models will impact sustainable mobility. The work documented in this paper focused on identifying available methodologies for assessing the sustainability impact of potential MaaS implementations from a whole system (STEEP—social, technical, economic, environmental, and political) perspective. In this research, a review was conducted of current simulation tools and models, relative to their ability to support transportation planners, to assess the MaaS concept, holistically, at a city level. The results presented include: a summary of the literature review, a weighted ranking of relevant transportation simulation tools per the assessment criteria, and identification of key gaps in the current state of the art. The gaps include capturing the interaction of demographic changes, mode choice, induced demand, and land use in a single framework that can rapidly explore the impact of alternative MaaS scenarios, on sustainable mobility, for a given city region. These gaps will guide future assessment methodologies for urban mobility systems, and ultimately assist informed decision-making.

This paper proposes a method of assigning trips to automated taxis (ATs) and designing the routes of those vehicles in an urban road network, and also considering the traffic congestion caused by this dynamic responsive service. The system is envisioned to provide a seamless door-to-door service within a city area for all passenger origins and destinations. An integer programming model is proposed to define the routing of the vehicles according to a profit maximization function, depending on the dynamic travel times, which varies with the ATs’ flow. This will be especially important when the number of automated vehicles (AVs) circulating on the roads is high enough that their routing will cause delays. This system should be able to serve not only the reserved travel requests, but also some real-time requests. A rolling horizon scheme is used to divide one day into several periods in which both the real-time and the booked demand will be considered together. The model was applied to the real size case study city of Delft, the Netherlands. The results allow assessing of the impact of the ATs movements on traffic congestion and the profitability of the system. From this case-study, it is possible to conclude that taking into account the effect of the vehicle flows on travel time leads to changes in the system profit, the satisfied percentage and the driving distance of the vehicles, which highlights the importance of this type of model in the assessment of the operational effects of ATs in the future.

This article analyses the impact that the confinement measures or quarantine imposed in Spain on 15 March 2020 had on urban mobility in the northern city of Santander. Data have been collected from traffic counters, public transport ITS, and recordings from traffic control cameras and environmental sensors to make comparisons between journey flows and times before and during the confinement. This data has been used to re-estimate Origin-Destination trip matrices to obtain an initial diagnostic of how daily mobility has been reduced and how the modal distribution and journey purposes have changed. The impact on externalities such as NO2 emissions and traffic accidents have also been quantified. The analysis revealed an overall mobility fall of 76%, being less important in the case of the private car. Public transport users dropped by up to 93%, NO2 emissions were reduced by up to 60%, and traffic accidents were reduced by up to 67% in relative terms.

The authors analyze the impact of a tax on sweetened beverages using a unique data set of prices, quantities sold, and nutritional information across several thousand taxed and untaxed beverages for a large set of stores in Philadelphia and its surrounding area. The tax is passed through at an average rate of 97%, leading to a 34% price increase. Demand in the taxed area decreases by 46% in response to the tax. Cross-shopping to stores outside of Philadelphia offsets more than half of the reduction in sales in the city and decreases the net reduction in sales of taxed beverages to only 22%. There is no significant substitution to bottled water and modest substitution to untaxed natural juices. The authors show that tax avoidance through cross-shopping severely constrains revenue generation and nutritional improvement, thus making geographic coverage an important policy decision.

In the Twentieth century transportation has been one of the most impactful drivers for economic and social development, while nowadays, it appears as a major cause of environmental and social problems. Even worse, the more transportation has become a relevant part in daily life and business, the more it is blamed for problems such as traffic congestion, car accidents, social economic inequality, energy consumption and pollution. Transportation is in fact caught in a vicious circle. Urban planning is forced to reduce transition costs, transforming cities in a sort of social network, and in parallel to orient mobility towards sustainability, both capable to convey socioeconomic development. Within this context, the University of Bologna has chosen a sustainable approach for its Multi-campus territorial structure, applying several sustainable mobility policies regarding public transportation, cycling, electric/hybrid car fleet and walking accessibility. The paper purpose is to show significative links between sustainable policy application and modal share, using data from an online survey submitted to university staff and students. Even gender influence on modal share has been investigated.

Motives: COVID-19 pandemic has caused worldwide implementation of unprecedented measures of physical distancing to decrease the potential of the COVID-19 infection. As cities respond to closure measures in order to flatten the infection curve, the challenges associated with the spread of the epidemic and the increasing numbers of infected and deaths that compel us to fundamentally rethink the formation of our cities, especially their streets, the research presents an urban review of the impact of the pandemic on cities and find solutions to recover, achieve a safe and sustainable healthy environment, and prepare better for any pandemic that may occur in the future, the research seeks to strengthen the theory of prevention, which the research proposes to call (urban immunity) by including social distancing as a design criterion in the city that has proven effective in flattening the curve. Aims: This paper focuses on the mechanisms related to sustainable mobility after COVID-19 in shaping urban mobility and initiating a green transformation in urban transportation rapidly by decarbonizing and promoting cycling and walking across all over the city. The research methodology depends on identifying the most important urban problems that Al-Dhubat Street suffers from and proposing solutions that reduce dependence on private transportation and move towards sustainable mobility as an important step in strengthening urban prevention against any epidemics that may occur in the future, and then testing indicators on the Al-Dhubat Street to identify effective indicators. Results: The research concluded that social distancing is the way back to active mobility by relying on walking and bicycles and works to restore the right of pedestrians in the streets and sidewalks instead of cars and thus achieve sustainable urban development, which enhances the urban immunity of the city against any other epidemics may occur in the future. With the proposed interventions on Al-Dhubat Street we can keep car use low and promote walking and cycling for a sustainable, equitable, habitable, and healthy community after the pandemic.

The pavements of the sidewalks are not simple roofs for the floor of cities. The correct specification and application of the materials not only guarantees the accessibility of this space, but also favors and enhances the urban mobility of pedestrians, the walkability, much defended by several professionals of urbanism. Have you stopped to observe the city we live in? The streets, the sidewalks and all of your public areas? Note the immense "invasion" of public space, making life on sidewalkssomething stimulating and interesting, by the enormous confusion implanted: kiosks, street vendors / street vendors, cars parked in a forbidden place and sometimes on the sidewalks, barbecues, holes, steps, obstacles, furniture and urban equipment very poorly located,results of the complete dysfunction ofthis space. The problem observed reflects the current dismay of people and public authorities in relation to accessibility, mobility and safety of people, especially those with reduced mobility,disabled or not. That said, this work objectives tofind a floor of easy installation and low cost that meets the principles of universalaccessibility, urban aesthetics and enhances the mobility of people in the city with autonomy and security. Based on an observational and photographic study of the sidewalks of the Pelinca neighborhood, together with a technical survey of existing sidewalks,the information obtained will be compared with the guidelines contained in the accessibility and urban mobility legislation in force, whether at the municipal, state and federal levels. The data extracted in the evaluation of existing floors, will provide subsidies, for the identification of a new type of pavement, contributing to the Public Power in the elaborationof booklets for the implementation and or adoption of guiding measures for the construction and reformulation of sidewalks, in the city of Campos dos Goytacazes

The COVID-19 pandemic had a significant effect in urban mobility, while essential changes are being observed in travelers’ behavior. Travelers in many cases shifted to other transport modes, especially walking and cycling, for minimizing the risk of infection. This study attempts to investigate the impact that COVID-19 had on travelers’ perceptions towards bike-sharing systems and whether the pandemic could result in a greater or lesser share of trips that are being conducted through shared bikes. For that reason, a questionnaire survey was carried out in the city of Thessaloniki, Greece, and the responses of 223 people were analyzed statistically. The results of the analysis show that COVID-19 will not affect significantly the number of people using bike-sharing for their trips. However, for a proportion of people, bike-sharing is now more attractive. Moreover, the results indicate that bike-sharing is now more likely to become a more preferable mobility option for people who were previously commuting with private cars as passengers (not as drivers) and people who were already registered users in a bike-sharing system. The results also provide evidence about the importance of safety towards COVID-19 for engaging more users in bike-sharing, in order to provide them with a safe mobility option and contribute to the city’s resilience and sustainability.

The efficient functioning of the transport system in each area requires that account be taken of the fact that each journey consists of a chain of elementary movements on foot or by means of trans­port. The construction of an effective public transport system is one of the methods to reduce traffic congestion, especially in city centres. The inter-change synchronization is the way to increase the efficiency of public transport. The purpose of the paper is to present the results of research on the intensity of pedestrian traffic at interchanges as a function of time in the city of Radom. Pedestrian movements play an important role not only in the vicinity of transport nodes. Their production and quality also determine the assessment of these movements as one of the stages of production of combined movements. The tendency to pedestrian travel (or lack of it) also affects public and individual transport journeys. Based on the survey conducted in households, the structure of movement (size and motivations) of the inhabitants of Radom is given.

Transport of urban goods has a signifi cant impact on the lives of residents and the functioning of the local economy. At the same time, it creates numerous problems related to the impact on the environment and the surroundings. Thus, the distribution of goods in the city has a signifi cant impact on the lives of residents and tourists' impressions. Due to the fact that 25 percent EU emissions from transport come from urban areas, cities play a key role in mitigating the negative eff ects of transport. Many cities are currently implementing Sustainable Urban Mobility Plan (SUMP) that focus on people's mobility. In most cases, the distribution of goods is not mentioned in the SUMP or is mentioned briefl y. In the absence of clear guidelines for resolving urban transport issues, some cities have adopted various strategic documents and measures. In the absence of standardization of documents, it is diffi cult to compare them and determine the level of city advancement in the implementation of urban logistics measures. To overcome this problem, the EC initiated the concept of Sustainable Urban Logistics Plan (SULP). The article presents the structure and plan of implementing SULP.
