The article presents a method which helps local authorities to evaluate urban freight transport models. Given the complex requirements for input data and the inability to supply them for most cities, a proper quantitative evaluation of model functionality may be quite difficult for local authorities. Freight transport models designed to support sustainable urban freight transport objectives are a particular example. To overcome these difficulties, the structure of the method is based on a qualitative analysis of strategic and operational conditions of urban freight management for modelling purposes. A consistent set of criteria is developed to help with parameterising strategic objectives and the analytical requirements of tools to achieve those objectives. The problems of data availability and capture are also included. The method consists of three tiers that are arranged hierarchically to reflect the interrelations. The proposed method was verified against Gdynia’s (Poland) urban freight management requirements. The city was chosen for its early experience of urban freight studies and improvement measures and because it has already defined its strategic objectives. Two comprehensive freight transport models (Freturb and Wiver) and existing city’s transport model were evaluated. The results have ruled out the existing transport model rendering it ineffective as a tool to support urban freight management to meet the city’s strategic objectives. While Freturb turned out to be much better suited for the needs, dedicated models still face a basic barrier of cities having to redesign their systems for collecting urban transport data.

Sustainable Urban Mobility

The growing demand for passenger and freight transport in cities, resulting from the population growth in urbanized areas, has led to increasing problems with congestion, environmental pollution and, as a consequence, to a decrease in quality of life. This problem was noticed by the European Commission, which began to promote the concept of sustainable urban mobility plans (SUMPs). The efficient implementation of SUMPs requires tools for its evaluation. However, in the literature, most proposed assessment tools relate mainly to passenger transport, omitting the freight transport. The purpose of this paper is to utilize a multiple criteria analysis with the use of the Promethee method in order to assess the level of advancement of selected European Union (EU) capital cities in the field of sustainable urban mobility plan formulation and implementation. This method has been applied on the basis of a survey conducted among representatives of 15 EU capital cities and analyses of transportation plans. This research shows that cities that have a comprehensive transport plan consistently collaborate with different stakeholder groups, have implemented the greatest number of measures in the field of sustainable urban transport, and have achieved the best results in terms of safety and NO2 (nitrogen oxides) and PM (particulate matter) emissions.

The Impact

Assessment of pollutant emissions is a prerequisite for planning and development of sustainable urban transport systems. Majority of extant studies on sustainable urban transport is focused on pollution caused by urban passenger transport, with marked paucity of literature on the impact of urban freight transport. To partly bridge this gap, the paper objective is the impact assessment of selected regulative measures, i.e. fleet renewal on freight transport emissions. We used the case of Novi Sad to estimate the potential impact of selected restrictive measures on the external freight transport air pollution. To the best of our knowledge, this is one of the first studies on impact of urban freight transport on the air pollution in the cities in the Balkan region. Several research findings are of interest. Firstly, the analysis of particular gas emissions reveals expected overall positive effects of the fleet renewal in most of cases. Still, the total amount of same emissions hardly increase, so this particular measure is not enough to reach the ambitious EU strategy goals concerned with sustainable urban freight transport. Further, some negative impacts of restrictive measures on gas emissions were also recorded and discussed. The observed complex impact of restrictive measures on urban freight air pollution indicates that urban freight transport planning and modeling requires a comprehensive database, clear goals and higher priority of environmental criterion in traffic planning. Our results and recommendations may be useful for scholars, urban transport planners, policy makers and practitioners.

The Impact

In the era of the new economy, research on freight transport and logistics in urban areas can not ignore the impact of the internet on society. From the point of view of e-commerce, the Web is joined in the daily life of the Italians not only for the growing opportunities to shop at better conditions than the other channels, but for the enormous possibilities that the Internet provides for those who has time, desire and interest to search the site data and useful information to make more effective shopping for a product or a service. The effects of these changes on the transport demand are manifold: on the one hand, the use of virtual activities replaces a series of physical movements, on the other hand the individual who carries out these activities virtually could use the time saved to perform other tasks or perform another type of movement. No less important are the impact of e-commerce on the distribution, since the online purchasing determine, in a specific area, a number of points to be served with high variability and, therefore, quite different from the default items identified by the traditional commercial structure of that area. In the present work some studies on the effects of e-economy and e-commerce on passenger transport and freight transport are detailed and the processes of acquisition of the database for the development of a behavioral model for simulating consumers choices about e-shopping and shopping in trade are defined. The model allow to predict the effects of new technologies on consumers habits and act on demand, focusing on services that may mark the success of innovative approaches to the management of urban transport. The specifications, calibration and validation of models to choose between e-commerce and physical commerce are presented.

Transport Problems

Dynamic growth of automotive indicator and increasing level of freight being carried in the Polish cities are causing serious transport problems. Migration to the cities is a trend observed still in Poland that is expected to continue. Bottlenecks, delivery obstacles, congestion, traffic jams and air pollutions require prompt organizational and technological intervention. The article starts a discussion about the condition of the urban logistics in Poland, comparing various models from the local government authorities point of view and inhabitants. The author outlines the barriers and obstacles in the planning and implementing of the modern urban logistical solutions. The majority of municipal and local government authorities, despite the declared enthusiasm for the smart city concept, prefer traditional infrastructure investments, instead of joint and interdisciplinary planning of the combined organizational and technological solutions tailored to the needs of a specific city. There is an urgent need to introduce regulations limiting freight traffic in the Polish cities, road tolls depending on emissivity, payloads, parking infrastructure. There should be rules planned determining time windows in the urban transport, organizing in-city consolidation centers, etc. The paper includes recommendations for creating Urban Vehicle Access Regulation Schemes for the Polish cities. The article includes also the findings and recommendation for the Polish cities in the field of urban logistics. The author emphasizes, however, that there is still a lack of long-term investment plans in the field of logistics and freight transport in so-called smart cities. The paper demonstrates that the efficiency of the functioning of Po-land’s urban logistics network does not necessarily imply cost-intensive infrastructural development. The optimization of logistics activities should be brought about in urbanized areas primarily based on the organisational changes in the transportation system, customs, habits and behavioral patterns of its users as well as the altered functions of selected. Such an approach is the closest to the views expressed by the inhabitants; however, it all too often proves contradictory to the interests of the other stakeholders of the system. Any changes to the city’s transport layouts or systems, or mobility policies (as a broader concept), call for a broad public contribution when it comes to consulting projects and designing the improvements. Organisational and financial support is likewise indispensable, along with the development of an incentives system. The author also pointed out a need to monitor comprehensively the solutions in the field of urban logistics and urban freight transport of the Polish cities using socio-economic analysis tools. The selected methods of evaluating the urban logistics solutions, incl. comparative best practices analysis, have been discussed.

Structure Changes

This paper briefly reviews the existing Australian situation in respect of urban person and freight transport. It identifies those aspects likely to be sensitive to structural economic change and related changes. The extent of such sensitivity is discussed using such empirical evidence as is available. In particular the paper examines the possible effects on urban transport of such factors as changes in the demographic structure, changes in energy, institutional and political change, and technological change, as well as structural economic change.
