Before implementing an Urban Freight Transport (UFT) solution, certainty is required about the effectiveness of the considered alternatives. Selecting an effective solution necessitates the engagement of all stakeholders involved in the management of the UFT system. The aim of the study is the formulation of a common assessment platform for facilitating the selection of the most appropriate UFT solution, taking into account the solutions’ effectiveness and the stakeholder perceptions and consensus. Solution maturity, social acceptance, and user uptake, which are considered as the main drivers of stakeholders’ engagement, are evaluated based on a real time Delphi survey, in parallel with solutions’ sustainability dimensions (economy and energy, environment, society, transport, and mobility). The Delphi method emerges as a suitable tool in this direction as stakeholders’ subjective judgments, and not analytical techniques, are required. The platform is demonstrated through the assessment of ten UFT solutions by 184 stakeholders (public authorities, supply chain operators, and other interested groups) who reside in cities across the world. The results of the demonstration showed that Intelligent Transportation Systems (ITS) for freight monitoring and electric vehicles are the highest rated solutions, while drone deliveries are the lowest, reaching respectively the highest and lowest consensus levels.

In the past few years, tools have been developed based on different communication means with the purpose of achieving a safer, more efficient, and environment-friendly operation of vehicular flows in the transport systems. Some of the early means generally involved a very strong human participation. In the course of time and with the rapid progress made in electronics, telecommunications, and computer systems, such processes have become automated until generating a series of technologies that currently are incorporated into the single generic term of intelligent transportation systems (ITS). This research has multiple purposes. First, some characteristics of road freight transport in Mexico are presented. Then, with such characteristics under consideration, the ITS technologies with the largest potential for application to that transportation type are described. A vision of future implementation is shown. Finally, some conclusions are presented.

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.

Subject. The article considers functioning and development of process flows of transportation and logistics system of a smart city. Objectives. The study identifies factors and dependencies of the quality of human life on the organization and management of stream processes. Methods. I perform a comparative analysis of previous studies, taking into account the uniquely designed results, and the econometric analysis. Results. The study builds multiple regression models that are associated with stream processes, highlights interdependent indicators of temporary traffic and pollution that affect the indicator of life quality. However, the identified congestion indicator enables to predict the time spent in traffic jams per year for all participants of stream processes. Conclusions. The introduction of modern intelligent transportation systems as a component of the transportation and logistics system of a smart city does not fully solve the problems of congestion in cities at the current rate of urbanization and motorization. A viable solution is to develop cooperative and autonomous intelligent transportation systems based on the logistics approach. This will ensure control over congestion, the reduction of which will contribute to improving the life quality of people in urban areas.
