摘要:AbstractTravel Demand Management (TDM) measures, whose primary objective is to alleviate the impacts of traffic and congestion in the urban environment, are nowadays increasingly used to address complex transportation and mobility puzzles. One of the most representative TDM measures is the High Occupancy Vehicles (HOV) lane. This paper presents and discusses the results of the hypothetical implementation of an HOV lane in the CBD area of Thessaloniki, Greece. The impact evaluation was conducted through traffic simulation modeling techniques and the results are expressed in terms of environmental and traffic indicators. The environmental and energy aspects of the examined HOV lane are the focus of attention of the current study, in an effort to assess their contribution to rising sustainability issues. The HOV lane in Thessaloniki's case study proved to be, in principal, an efficient tool for managing transport demand. Nevertheless, there is a need for further examination of the impacts on the whole network.
