ABSTRACT

These days we can see a growing interest in city logistics. Agglomerations struggle with increasing transport flows which inevitably leads to traffic jams and ultimately to the emergence of road closures. Modern information technologies are of great importance in regulating such flows. Smart cities initiative which addresses numerous issues regarding information, technology, and communication in urban planning is related to these technologies. This concept has become increasingly popular among researchers from all over the world. Within the framework of city logistics, various tasks are solved in terms of content, including the problem of traffic regulation. Simulation technologies can serve as an excellent instrument to see how the implementation of intelligent transportation systems resolves this challenge. This article presents the results of applying an algorithm based on simulation of a transport infrastructure object which does not only provide a noticeable road congestion reduction but also a decrease in time spent by passengers in cars during traffic jams. Approximate calculations of socio-economic effects generated by implementation of the developed algorithm confirm the economic feasibility of its application in urban transport systems of megacities.

ABSTRACT

 Nowadays the growth of megacities is considerably constrained by their poor condition and inefficient functioning of various elements within the urban transport systems. Being the modern area of study, city-logistics solves the problems of traffic and ridership management. However, it is also necessary to expand the transport infrastructure, which could optimize the time of multimodal transportation. The projects of transport hubs development are becoming increasingly important. They act as the integral element for cooperation of urban passenger transport and improvement of passenger services quality. Generating significant public effects, these projects are highly effective for both investors and society as a whole. Using the available techniques, the authors of this article assessed social effects (positive externalities) for the development project of transport hub "Devyatkino" in St. Petersburg. Social effects include travel time minimization, mobility growth and transport safety enhancement. According to the results of the project assessment, it was established that the share of state funding could be increased, which differs from the project developers’ standards.

ABSTRACT

 Urban logistics seems to be a kind of «black box» for researchers and city authorities in the recent years, and as a result, a lot of research is limited to describing individual effects or setting out a course of planning a logistics system in urban conditions without taking into account some of its specific characteristics, such as influences of urban transport and environmental policy, urban spatial development; city authorities in turn prefer purely formal interaction with logistics companies and retail, introducing various kinds of prohibitive measures and without monitoring the results of their implementation. Thanks to the ongoing industrial revolution, radical changes are taking place, and digital technologies allow introduction of new management methods, which leads to fairly radical changes in city logistics. This article presents an overview of the changes that will affect the structure of the logistics chain. These changes are organized into 5 groups of factors: new technologies development, economic, environmental, social factors, external threats. Timely preparation for future changes will allow both logistics companies to correctly allocate available resources in the modernization of the logistics system, and city authorities to amend urban policy in the field of management and coordination of city logistics.

ABSTRACT

Effectiveness of urban transport systems development is a necessary condition for agglomerations economy development. Urban transport systems should provide rapid and comfortable passenger transportations. They must comply with the requirements of high performance and hourly transport accessibility. The purpose of urban transport system management is to provide compliance with these requirements while minimizing the total social costs. The assessment of urban transport systems effectiveness should consider both multiple social effects resulting from their functioning and the total social costs that include a number of externalities. Social effects include an assessment of travel time reduction, the growth of mobility and population economic activity, the growth rate of the agglomeration economy. The necessity to develop common approaches to the assessment of these effects and their application in the strategic planning of agglomerations development becomes obvious. The paper deals with the problems of multimodal passenger transportation development on the example of St. Petersburg agglomeration. The calculation model for estimation of sales integration economic effect is offered.

ABSTRACT

One aspect of the modern economy is urbanization of the population in the countries of the European Union and the Russian Federation. The consequences of urbanization are difficult traffic situation in metropolises and an increase of transportation costs. It should be noted that the high congestion of city roads have, first of all, a negative impact on the movement of specialized vehicles of ambulances, flying squad, emergency. The specified reasons cause the trouble with promptly assistance provision to the population in the emergency situations. So it is determined the interest in these field research aimed to improve the effectiveness of city logistics, logistics of urban transport systems. Despite numerous attempts by both scientists and practice experts till now the issues of decrease of transport intensity in large cities are not finally resolved. Thus, further research in this direction, in particular, with refinement and adaptation of modern methods and models of logistics theory based on passenger traffic flows and specialized transport in the metropolises is required.

The provided studies allow to allocate aggregated group of methods and models and to identify the scope of their rational use in the organization of the movement and urban traffic management. Another poorly studied aspect is the ways of supporting free movement of special transport taking into account the implementation of “just-in-time” logistics concept to special transport. For this purpose, special transport routes are classified, and a schematic diagram of the special services organization a key component of which is an intelligent transport system is prepared. According to the proposed approach, the routes design taken by special transport should be supplemented by administrative decisions that are associated with the growth of the special vehicles effectiveness (primarily to minimize the arrival time to the point of destination).
