Advances in Transportation Studies is a quarterly (four-monthly) and a refereed journal that contains international and national review papers on the most recent outcomes of studies and advanced research in the field of Road and Highway Engineering with a particular focus on the safety, effectiveness, efficiency and sustainability of transport. Topics discussed examining design standards and regulations, impact of human factors on facilities design, geometry, facilities construction, pavement design and management for safety improvement, environmental impact make it essential reading for Transportation Scholars and Researchers, Transportation Facilities Engineers, Transportation planners and Modellers.Moreover special issues on particular topics, such as policy analysis, formulation and evaluation, interaction with the political and socio-economic environment, management and evaluation of trasportation systems, are published from time to time and provide a wide range of information for Administrators and Policy Analysts, too. The journal contains in-depth, state-of-the-art papers on transport topics.CONTENTSSection AA. LoizosRoad Deterioration Modeling in PMSs: sensitivity and global applicabilityB. Crisman, P. Perco, A.
