Abstract:When traffic demand deviates from the expectation during the operation phase of highway build-operate-transfer (BOT) project, the dynamic adjustment method on the toll and concession period is helpful to ensure the benefits of the public, the government and the project company. This paper developed an expected profit function of the project company in the remaining (T-n) years based on the actual profit of first n years in order to ensure the project company has a reasonable profit. Furthermore, it discussed the single adjustment and linkage adjustment decisions on the toll and concession period to avoid gaining excess profit or being unable to gain the expected profit for the project company in the case of the traffic demand curve parallel shifts rightward or leftward. Finally, a numeric example was adopted to verify proposed model and provide the reference on toll and concession period adjustment decisions for the government and the project company during operation phase of highway build-operate-transfer (BOT) project.
