Abstract: For the double bottlenecks traffic network containing one bottleneck in both of the two consecutive road part, the travel behavior of the household which needs to go through double bottlenecks to reach two destinations: the school and then the company are investigated. This paper firstly proposes the user equilibrium model under no-toll situation. Then, we study the congestion charge model, and according to the discussion on the difference of starting time between school and work, the optimal toll scheme and charging time window that minimize the system total cost are obtained. We find that congestion charge can effectively reduce the system cost, and that a lower system cost can be obtained when the difference between the two desired arrival times is small. Finally, the numerical results verify that the peak time length remains unchanged, and achieve the charging plan based on which the system cost is optimal.
