The main aim of the Journal is to bring together the research work being done in the field of Transport Economics and arrange it organically in the form of a synthesis between theory and fact. The situation facing transport economics is one in which old problems remain to be solved and new ones have been created by a wider range of information and improved methods of analysis. In addition, foreseeable development in the internal logic of theories and the formulation of fresh hypotheses to interpret complex phenomena, both economic and non-economic, are becoming the object of further research for which the Journal is intended to be a medium of expression and comparison. It is important in this respect to stress the fact that transport economics is prepared to take advantage of contributions from allied sciences and combine them in providing a more convincing interpretation of realities together with solutions to concrete problems. Within this framework the contributions to the Journal, though differing in standpoint and cultural background, will all be expected to maintain a rigorous standard of scientific scholarship. Topics are approached from any discipline or perspective: economics, management, engineering, mathematics, statistics, etc.
