"Economy of scale and the role of publicly available congestion information for local delivery industry: Agent-based simulation approach"
This exploratory study use the agent-based model to create a virtual environment in which small and large firms enter into a new market under several different conditions to examine the validity of the hypotheses that in the absence of publicly available traffic information, the competitive advantage of larger companies, resulting from having accurate information on the traffic condition (because they possess greater ability to gather congestion information using their own trucks as probes), can be large enough to prevent smaller companies to enter into a new market for which the pattern of recurring traffic congestion is not well known. Thus, the traffic information system may provide additional benefits that have not been recognized in the past. The output from the simulations runs show that while traffic information system reduces the entry cost, especially for the small firms, the average cost savings over the simulation cycle of 70 time periods is equivalent of 3% of the total cost. Also, the saving in the entry cost is affected by the level of congestion and also the variability in the link travel times. Although determining whether the entry cost is large enough to prevent the smaller companies to enter the new market in the real world will require further analyses using the empirical data. However, it is clear that the provision of the publicly available traffic information will improve the odds of entry and survival for the small firms.
