ارزیابی هزینه های اجتماعی حاشیه ای به علت تراکم با استفاده از عملکرد جریان سرعت

The scope of the present paper is the description of a methodological approach for the assessment of the marginal social cost due to congestion along the urban road network. The first part involves an overview of available methodologies for the assessment of costs due to congestion followed by the description of the proposed approach, which takes advantage of the speed-flow functions of representative segments of the categorised urban road network. The main feature of the approach is that it allows for the estimation of the marginal social cost due to congestion using floating car data (FCD) as input. A pilot application in the city of Thessaloniki, Greece and a comparative analysis of the results in relation to the results of recent studies in Europe are presented in the next part. The paper is concluded with the discussion of the prospects and obstacles for the future implementation and enhancement of the methodological approach.
