Abstract:
One important problem in all, particularly in developing countries, is shortage of funds to invest in infrastructure projects. One way to lessen this difficulty is to benefit from the private sector participation in this respect. Build-Operate-Own-Transfer (BOT) is a Public-Private-Partnership (PPP), in which the private sector invests and builds a (e.g. road) project, operates it for a specified period of time to collect the tolls to return the investment cost plus the specified attractive rate on it, and then transfer it to the public sector. This research, which is a continuation of previous endeavors in this area, formulates the problem, discusses the multiplicity of the solutions, and presents a method to evolve the solution of an existing incremental traffic assignment procedure toward the optimum solution. It also presents an Ant System to design the level of public sector subsidy to each road project. A software has been developed to do this design, and perform sensitivity analysis on overall budget level
