TRAVEL DISTRIBUTION MODELS IN JGP SYSTEMS

Abstract

Modern methods of urban traffic planning have been inextricably linked to the application of computer technology since its inception. Without the use of computers, it would not be possible to process and analyze the vast amount of data collected for traffic research purposes. Also, the development and application of various models and simulation processes in traffic analysis and forecasting can only be satisfactorily accomplished through the use of computers. Faster, more powerful computers accessible to everyone and simpler programming have accelerated the development of different approaches to the same problems that have resulted in a large number of alternative models and procedures that can be used at different stages of traffic planning. The application of modern computer technology is of particular importance in the field of development and application of travel models on the network of public urban transport lines – UGP.

Models of distribution of journeys to UGP networks, both from a theoretical and practical point of view, represent for many reasons one of the most complex forms of traffic models and as such represent a newer area in traffic planning. The main problem in the development and implementation of these models is an adequate database related to the spatial and visual distribution of travel, as well as the selection of the relevant – peak load on the basis of which the transport capacities in the PPP system are dimensioned. The usual process for collecting this data is through extensive surveys that require significant funding and complex organization.
