Defining of Factors for the Improvement of Suburban Traffic in Zagreb Metropolitan Area (Report‪)‬

1. INTRODUCTION Defining of improvement factors of suburban traffic represents a significant enhancement of its future development in the Zagreb metropolitan area. The results of past research (Brkic et al., 2001) include models that understand substantial investments in the construction of new infrastructure which would result in the increase of the transport capacity and the quality of providing transport services in suburban traffic, requiring at the same time substantial financial investments. Besides, it may be assumed that such an improvement of this traffic system can cause the occurrence of major increase in the demand for the transport service in the suburban traffic which would in that case, without additional system improvement measures, result in its overload, including also reduced quality of the transport service.
