This article sets out an approach to the problem of strategic spatial development through transport network re-organisation. The paper describes an expert system for strategic transport planning and introduces the concept of the Minimal Transport Standard (MTS). The authors have studied the experience of developed and developing countries and formulated a set of indices on the basis of ecological, economic, social and geopolitical parameters of spatial development.
The primary task of the expert system is to increase the quality of life by means of transport. Thus, effectiveness of transport functioning is of second priority and serves to ensure improvement and maintenance of the general conditions of living and business activity. The expert system is universal, but it has been mainly used in developing countries and the regions of the Russian Federation.
Since 1986 when P.Bonsall and H.Kirby (1986) drew attention to the problem of using expert systems in the transport sector, no serious attempt has been made to create an expert system for strategic transport planning. There are many systems for tackling specific transport problems such as optimisation of traffic flows (e.g., EMME/2, MVA), effectiveness of road projects (HDM-IV), road safety and preservation of the environment (Fergusson & Ross, 1992).
Moreover, quite a few systems have been designed for dealing with concrete problems of traffic organisation on transport routes, especially in a city. These are Intelligent Transport Systems, but they solve mainly technical problems of traffic organisation.
A relatively big and constantly renewed list of software products for all directions of transport development is available in the annual McTrans (1998, 1999). But we could not trace any system for strategic transport planning there.
Hence there is a need for strategic expert systems that will address the re- estimation of a fundamental understanding of the role of transport. For example, a lot of traditional views, approaches, methods, and criteria for measuring transport effectiveness changed drastically with the advent of a market economy in so many. countries. Before, transport was based on determination of volumes - the achievement of transport activity. Certain systems for planning of transport development are oriented not so much towards the transport service users, but more towards the providers of transport services. Moreover, it often happens that interests of different transport modes are in conflict. That is why the issue of risk reduction by means of transport network improvement appears to be of extreme importance. Its effective solution will influence the economic and social development and ecological situation in a region. Thus, the achievement of desirable social and economic conditions in a region becomes the task of the strategic planning of any transport network.
