Introduction: In the 21st century, cities in developing countries have witnessed faster growth as compared with cities in developed countries. Countries like India, China and Brazil have one of the most densely populated cities in the world. The transport infrastructure in these cities struggles to deal with the increasing population and geographic sprawl. Though some efforts are made to improve the transportation systems in these cities, urban freight transport is largely overlooked as the focus remains on passenger transport. Methods: This study aims to assess the impacts of the city’s geographic sprawl on urban freight transport using the example of the textile industry in Surat, India. The sprawl of the city and its textile industry is measured based on historical maps, Google imagery, and establishment surveys. Changes in urban freight trip lengths are determined using the data of a commercial vehicle drivers’ survey. Results: In the last two decades, the city expanded geographically by almost three times. The relocation of textile manufacturing units led to a 40% increase in trip lengths and additional 56 tons of carbon dioxide generation per year. Due to the city sprawl, the overall efficiency of the urban freight transport system reduced. There is a need for a holistic planning approach towards urban freight movement and related urban infrastructure for sustainable freight flows. This can serve as a policy framework to decide on the location of a logistics hub or as guidelines to allocate manufacturing enterprises in the proximity of the urban area, thus enabling sustainable development of the city.

Complex Subject

The urban freight transport (UFT) is an important component of the urban logistics. It represents a driving force for the economic dynamics and attractiveness of a city. It can be treated as all movements of goods necessary for the economic activities, the institutions and the residents of urban life. Through, it faces with problems relating to the congestion, unsafety, atmospheric and noise pollution that constrain its performance and hinder its development. This performance is a complex subject on which a great deal of research has emerged in the last decade. Accordingly, this paper aims to develop a model for assessing the performance of the UFT. The objective is to identify the determinants of the performance of the urban freight transport and measure the impact of each factor. Therefore the first part of this article concerns the elaboration of the model and the formulation of the hypotheses. First, an overview of the factors that could influence the performance of the UFT was identified based on a literature review. The result of this step allowed to model, by mobilizing the GRAI grid (Graph of results and interrelated activities), the UFT system in order to release the decisional links between these factors. Then, the grid will be decomposed into hypotheses explaining the relations between the factors and the performance of the UFT. The formulation of each hypothesis will be based on all the theoretical works that have treated it. The second part includes the empirical study to test the model using the partial least squares (PLS) analysis. Therefore, we conducted a survey among managers and users of the UFT in the city of Fez. A hypothetico-deductive approach has been used with a sequential methodological complementarity between qualitative analysis for exploratory purposes and the support of quantitative analysis for confirmation. The results of the test, confirm a significant influence of the identified factors on the UFT performance. The practical scope of this paper is to provide a decision-making framework for urban management department explaining the impact of these factors on the UFT performance.

Charging Strategy

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.
