This paper discusses the awarding of terminals in European ports from an EU legal and policy context. It also seeks to provide in-depth information on current practices and perceptions of port authorities around Europe on tendering and contractual arrangements linked to the awarding of terminals. The relevant issues relate to the terminal awarding processes, the duration of the terminal award contract and the contract stipulations. The paper also seeks to understand whether the practices are influenced by factors such as terminal size, the competitive environment in which the port operates and the geographical location.

In addition to a synopsis of public transport operations in post-communist East Europe, the first part of this article presents an overview of public transport operations in Tirana from 1990 to the present day. The second part of the article discusses the findings of three sets of transportation surveys.

Abstract: Gap maintaining behavior significantly affects the traffic flow modeling under heterogeneous traffic conditions. The clearance between two adjacent moving vehicles varies depending on several traffic conditions. From the data collected on the gap maintaining behavior it has been observed that vehicles maintain different gaps when travelling under different traffic conditions and this is also influenced by lateral position of the vehicle. Mallikarjuna (2007) has found that this variable gap maintaining behavior can be explained using a macroscopic traffic characteristic called area occupancy. In this study, these relationships would be used in deciding the cell width which is the basic input for cellular automata (CA) based heterogeneous traffic flow models. It is proposed that the dominant vehicle in the traffic stream, its lateral position, and lateral gaps on either side are the governing factors in deciding the cell width. Cell width has been finalized based on this input and it is found to be varying when area occupancy is varying from 3 to 15%. Type: Articolo 2010-01-01T00:00:00Z
