Demand Responsive Transit

Demand responsive transit (DRT) can provide an alternative to private cars and complement existing public transport services. However, the successful implementation of DRT services remains a challenge as both researchers and policy makers can struggle to determine what sorts of places or cities are suitable for it. Research into car-dependent cities with poor transit accessibility is sparse. This study addresses this problem, investigating the potential of DRT service in Wayne County, U.S.A., whose dominant travel mode is private car. Using an agent-based approach, DRT is simulated as a new mobility option for this region, thereby providing insights into its impact on operational, user, and system-level performance indicators. DRT scenarios are tested for different fleet sizes, vehicle occupancy, and cost policies. The results show that a DRT service in Wayne County has a certain potential, especially to increase the mobility of lower-income individuals. However, introducing the service may slightly increase the overall vehicle kilometers traveled. Specific changes in service characteristics, like service area, pricing structure, or preemptive relocation of vehicles, might be needed to fully realize the potential of pooling riders in the proposed DRT service. The authors hope that this study serves as a starting point for understanding the impacts and potential benefits of DRT in Wayne County and similar low-density and car-dependent urban areas, as well as the service parameters needed for its successful implementation.

The dynamic development of urban areas poses increasingly more challenges for the provision of transport services for the population. The concentration of the economic potential and population in the metropolitan areas results in the occurrence of large transport needs, and when these needs are met at the same time, the phenomenon of congestion occurs. The purpose of the article is to research the relationship between various factors contributing to congestion in urban traffic and the level of congestion in Polish cities. The authors have used statistical methods such as correlation and regression analysis. The research has shown that the most statistically significant relationships have occurred in the case of the number of business entities and the number of passenger cars. It can be concluded that the demand side factors are more important in Polish cities than the supply side factors or perhaps the current transport policy is ineffective. When effectively applied, transport policy instruments can play a special role. These instruments can contribute to reducing congestion in various ways, i.e. by implementing various sub-objectives, which include reducing the need to travel, reducing the use of passenger cars, improving the functioning of public transport and use of the infrastructure. The results of this study can be useful for transport policy makers at central, regional and local levels.

Platformization affects the entire urban transport sector, effectively blurring the division between private and public transport modalities; existing public–private arrangements have started to shift as a result. This chapter analyzes and discusses the emergence of a platform ecology for urban transport, focusing on two central public values: the quality of urban transport and the organization of labor and workers’ rights. Using the prism of platform mechanisms, it analyzes how the sector of urban transport is changing societal organization in various urban areas across the world. Datafication has allowed numerous new actors to offer their bike-, car-, or ride-sharing services online; selection mechanisms help match old and new complementors with passengers. Similarly, new connective platforms are emerging, most prominently transport network companies such as Uber and Lyft that offer public and private transport options, as well as new platforms offering integrated transport services, often referred to as “mobility as a service.”

Future Vision

The smart city transport concept is viewed as a future vision aiming to undertake investigations on the urban planning process and to construct policy-pathways for achieving future targets. Therefore, this paper sets out three visions for the year 2035 which bring about a radical change in the level of green transport systems (often called walking, cycling, and public transport) in Turkish urban areas. A participatory visioning technique was structured according to a three-stage technique: (i) Extensive online comprehensive survey, in which potential transport measures were researched for their relevance in promoting smart transport systems in future Turkish urban areas; (ii) semi-structured interviews, where transport strategy suggestions were developed in the context of the possible imaginary urban areas and their associated contextual description of the imaginary urban areas for each vision; (iii) participatory workshops, where an innovative method was developed to explore various creative future choices and alternatives. Overall, this paper indicates that the content of the future smart transport visions was reasonable, but such visions need a considerable degree of consensus and radical approaches for tackling them. The findings offer invaluable insights to researchers inquiring about the smart transport field, and policy-makers considering applying those into practice in their local urban areas.

There is currently interest in the design of small electric vertical take-off and landing aircraft to alleviate ground traffic and congestion in major urban areas. To support progress in this area, a conceptual design method for single-main-rotor and lift-augmented compound electric helicopters has been developed. The design method was used to investigate the feasible design space for electric helicopters based on varying mission profiles and technology assumptions. Within the feasible design space, it was found that a crossover boundary exists as a function of cruise distance and hover time where the most efficient configuration changes from a single-main-rotor helicopter to a lift-augmented compound helicopter. In general, for longer cruise distances and shorter hover times, the lift-augmented compound helicopter is the more efficient configuration. An additional study was conducted to investigate the potential benefits of decoupling the main rotor from the tail rotor. This study showed that decoupling the main rotor and tail rotor has the potential to reduce the total mission energy required in all cases, allowing for increases in mission distances and hover times on the order of 5% for a given battery size.

Abstract Background The use of illicit substances causes various health and social problems globally. Moreover, open drug use and dealing in urban areas, i.e., open drug scenes, can cause public order problems, lead to the recruitment of marginalized and young people for drug use or sale, and induce feelings of insecurity in the general public. Although some international studies have described various ways to manage open drug scenes, such as law enforcement and social interventions, there is limited knowledge about the facilitators and barriers promoting or impeding the implementation of such interventions. The aim of the current study was to explore how different authorities describe the nature of two open drug scenes in Stockholm and to derive authorities’ perspective on facilitators and barriers to implementing interventions to reduce open drug dealing, drug use, and related problems at these locations. Methods Semi-structured interviews with police officers, security staff, social workers, and municipality officials (n = 21) in the municipality of Stockholm were conducted and analyzed by qualitative content analysis. Results The analysis of the interviews generated the following categories: Problems, Interventions, Organizational factors, and External factors, revealing information about the strategic and daily counteracting work occurring at the open drug scenes as well as authorities’ perceptions of facilitators and barriers to implementing interventions to reduce open drug dealing, drug use, and related problems. Facilitators included motivated and skilled professionals and organized collaboration between key actors. Prominent barriers were a lack of resources to maintain personnel continuity at the scenes, policies that impede information sharing and put security staff in danger, and people who use or sell drugs without having residence permits. Conclusions To increase the possibility of successful implementation of interventions to counteract open drug dealing, politicians and authorities should pay attention to collaboration between key actors, sufficient resource allocation, possible modification of policy governing professional duties, and remedies to the vulnerability of individuals without residence permits.

Electric cargo bicycles have become a popular mode of transport for last-mile goods deliveries under conditions of restricted traffic in urban areas. The indispensable elements of the cargo bike delivery systems are loading hubs: they serve as intermediate points between vans and bikes ensuring loading, storage, and e-vehicle charging operations. The choice of the loading hub location is one of the basic problems to be solved when designing city logistics systems that presume the use of electric bicycles. The paper proposes an approach to justifying the location of a loading hub based on computer simulations of the delivery process in the closed urban area under the condition of stochastic demand for transport services. The developed mathematical model considers consignees and loading hubs as vertices in the graph representing the transport network. A single request for transport services is described based on the set of numeric parameters, among which the most significant are the size of the consignment, its dimensions, and the time interval between the current and the previous requests for deliveries. The software implementation of the developed model in Python programming language was used to simulate the process of goods delivery by e-bikes for two cases—the synthetically generated rectangular network and the real-world case of the Old Town district in Krakow, Poland. The loading hub location was substantiated based on the simulation results from a set of alternative locations by using the minimum of the total transport work as the efficiency criterion. The obtained results differ from the loading hub locations chosen with the use of classical rectilinear and center-of-gravity methods to solve a simple facility location problem.

The impact of implementation of cohesion policy on the sustainable development of EU countries is of great interest and presents a number of actual challenges. This research aims to evaluate the impact and the effects of the cohesion policy among the Member States using hierarchical clustering analysis in order to identify how the selected variables affect the sustainable development adopted models. The variables used in the analysis were selected on the basis of official data provided by the European Commission, SDG Index and Dashboards Reports and the EU Cohesion Monitor. The results of the research have led to the grouping of the 28 Member States in a number of six clusters, identifying performers but also those countries that have a high potential for sustainable development or which require increased attention to be sustained in recovering existing gaps. The results of the study can be a starting point for policy makers and other stakeholders involved in their efforts to support sustainable development through effective and effective policies.

Redesigning and retrofitting cities so they become complex systems that create ecological and cultural–societal health through the provision of ecosystem services is of critical importance. Although a handful of methodologies and frameworks for considering how to design urban environments so that they provide ecosystem services have been proposed, their use is not widespread. A key barrier to their development has been identified as a lack of ecological knowledge about relationships between ecosystem services, which is then translated into the field of spatial design. In response, this paper examines recently published data concerning synergetic and conflicting relationships between ecosystem services from the field of ecology and then synthesises, translates, and illustrates this information for an architectural and urban design context. The intention of the diagrams created in this research is to enable designers and policy makers to make better decisions about how to effectively increase the provision of various ecosystem services in urban areas without causing unanticipated degradation in others. The results indicate that although targets of ecosystem services can be both spatially and metrically quantifiable while working across different scales, their effectiveness can be increased if relationships between them are considered during design phases of project development.

Purpose The purpose of this paper is to investigate the budgeting practices in the Tanzanian Central Government. New budgeting reforms were introduced following exhortations from the bodies such as the UN, the World Bank and the IMF and reflect the new public management (NPM). Design/methodology/approach A grounded theory methodology was used. This methodology is inductive, allowing phenomena to emerge from the participants rather than from prior theory. This ensures both relevance and depth of understanding. Findings The principal research findings from the data concern the central phenomenon of “struggling for conformance”. Tanzanian Central Government adopted innovations in order to ensure donor funding by demonstrating its ability to implement imposed budgetary changes. Organizational actors were committed to these reforms through necessity and struggled to implement them, rather than more overtly resisting them. Research limitations/implications The research is subject to the usual limitations of case study, inductive research. Practical implications This research has several implications for policy-makers of NPM and budgetary reforms. These include the recognition that the establishment of the rules and regulations alone is not adequate for the successful implementation of budgetary and NPM reforms and should involve a comprehensive view of the nature of the internal and external environment. Originality/value There are few empirical papers of NPM accounting practices being implemented in the public sector of developing countries and none at all based in Tanzania. The paper identifies the existence of struggling to conform to reforms rather than resistance identified in prior research.
