Limited data is available on the size of urban goods movement and its impact on numerous aspects with respect to livability such as emissions and spatial impact. The latter becomes more important in densifying cities. This makes it challenging to implement effective measures that aim to reduce the negative impact of urban good movement and to monitor their impact. Furthermore, urban goods movement is diverse and because of this a tailored approach is required to take effective measures. Minimizing the negative impact of a heavy truck in construction logistics requires a different approach than a parcel delivery van. Partly due to a lack of accurate data, this diversity is often not considered when taking measures. This study describes an approach how to use available data on urban traffic, and how to enrich these with other sources, which is used to gain insight into the decomposition (number of trips and kilometers per segment and vehicle type). The usefulness of having this insight is shown for different applications by two case studies: one to estimate the effect of a zero-emission zone in the city of Utrecht and another to estimate the logistics requirements in a car-free area development.

Although the interest in urban freight transport is growing, it is commonly seen as an area in which there is, for several reasons, a lack of research, especially if you compare it with the amount of research that deals with passenger transport. The attention of governments especially for urban goods movement has increased over recent years and with that the number of studies in the urban goods movement field. However, the practice of city logistics policies is not very often the result of detailed analyses and evaluations. This is reflected in similar types of regulations repeated through the different cities regardless of their characteristics, the same schedules for time windows and load zones, and the failure to recognise different types of urban distribution which require different types of regulations. Apart from copying regulation frameworks, however, cities hardly share information, knowledge or cooperation. The lack of national or regional bodies dealing with city logistics, as there exist for urban passenger traffic, is significant. In this paper we will address the main research contributions in city logistics and try to illustrate how the research contributions are (not) related to the daily practice of policymaking and town planning. Finally we will end with the conclusion that a real gap exists between research and practice and provide some explanations, conditions and directions for setting up new research projects.

from the article: "Abstract The way in which construction logistics is organised has considerable impact on production flow, transportation efficiency, greenhouse gas emissions and congestion, particularly in urban areas such as city centres. In cities such as London and Amsterdam municipalities have issued new legislation and stricter conditions for vehicles to be able to access cities and city centres in particular. Considerate clients, public as well private, have started developing tender policies to encourage contractors to reduce the environmental impact of construction projects. This paper reports on an ongoing research project applying and assessing developments in the field of construction logistics in the Netherlands. The cases include contractors and third party logistics providers applying consolidation centres and dedicated software solutions to increase transportation efficiency. The case show various results of JIT logistics management applied to urban construction projects leading to higher transportation efficiencies, and reduced environmental impact and increased production efficiency on site. The data collections included to-site en on-site observations, measurement and interviews. The research has shown considerable reductions of vehicles to deliver goods and to transport workers to site. In addition the research has shown increased production flow and less waste such as inventory, waiting and unnecessary motion on site."

The debate on tourism in cities, both academically and in practice, has for a long time taken place in relative isolation from urban studies. Tourism is mostly addressed as an external agent and economic force that puts pressure on cities rather than as an interdependent part of city systems. The recent debate on city touristification and excessive dependence on the visitor economy, as well as the associated processes of exclusion, and displacement of local city users, serves to highlight how tourism is an integral part of urban developments. A wider urban perspective is needed to understand the processes underlying the tourism phenomena and more transdisciplinary perspectives are required to analyze the urban (tourism) practices. The current article seeks to contribute to such a perspective through a discussion of the literature on urban and tourism studies, and related fields such as gentrification, mobilities, and touristification. Based on this, theoretical reflections are provided regarding a more integral perspective to tourism and urban development in order to engage with a transversal urban tourism research agenda.

Urban freight transport is frequently censured for its unsustainable impacts. Although our current urbanized civilization requires an efficient freight transport system in order to sustain it, the common perception is that urban freight transport has negative impacts on all sustainability issues: social, economic and environmental (also known as the triple P: people, profi t and planet). Urban freight transport, or urban goods movement, is identifi ed as having the following unsustainable eff ects on: people, such as the consequences of traffi c accidents, noise nuisance, visual intrusion, smell, vibration and the consequences of (local) emissions, such as NOx and PM10, on public health; profit, such as inefficiencies (especially for carriers) due to regulations and restrictions, congestion and reduced city accessibility; the planet, such as the contribution of transport to global pollutant emissions (CO2) and the consequences for global warming.

In a matter of weeks last year, discussions regarding tourism in cities changed from how to deal with overtourism to how to deal with ‘no tourism’. Shortly thereafter, a great number of posts on LinkedIn, websites, and blogs highlighted how the tourism crisis that resulted from the COVID-19 pandemic could help reinvent tourism, into something more equal, inclusive, and sustainable. And so, online – at leastin mypersonalonlinebubble – there seemedtobe a real momentum for proper, transformative changes in (urban) tourism. How can we rebuild urban tourism in a sustainable and resilient way?

This article analyses four of the most prominent city discourses and introduces the lens of urban vitalism as an overarching interdisciplinary concept of cities as places of transformation and change. We demonstrate the value of using urban vitalism as a lens to conceptualize and critically discuss different notions on smart, inclusive, resilient and sustainable just cities. Urban vitalism offers a process-based lens which enables us to understand cities as places of transformation and change, with people and other living beings at its core. The aim of the article is to explore how the lens of vitalism can help us understand and connect ongoing interdisciplinary academic debates about urban development and vice versa, and how these ongoing debates inform our understanding of urban vitalism.

The transition from diesel-driven urban freight transport towards more electric urban freight transport turns out to be challenging in practice. A major concern for transport operators is how to find a reliable charging strategy for a larger electric vehicle fleet that provides flexibility based on different daily mission profiles within that fleet, while also minimizing costs. This contribution assesses the trade-off between a large battery pack and opportunity charging with regard to costs and operational constraints. Based on a case study with 39 electric freight vehicles that have been used by a parcel delivery company and a courier company in daily operations for over a year, various scenarios have been analyzed by means of a TCO analysis. Although a large battery allows for more flexibility in planning, opportunity charging can provide a feasible alternative, especially in the case of varying mission profiles. Additional personnel costs during opportunity charging can be avoided as much as possible by a well-integrated charging strategy, which can be realized by a reservation system that minimizes the risk of occupied charging stations and a dense network of charging stations.

From the article: "ABSTRACT: The research group Supply Chain Redesign in the Built Environment of HU University of Applied Sciences is working on research that combines principles of the circular economy with open source architectural design & urban planning. The aim is finding new ways to re-use demolition waste and recycled materials in small scale urban area developments. And to “democratize” traditional processes in the built environment. Different recent studies have shown the potential benefits, such as a reduction of emissions. In “Hof van Cartesius”, a practical case-study in Utrecht, the ambitions and implications of this approach are being questioned, investigated and tested."
