When there's heavy traffic passing off-ramp of urban freeway and close to joint section, the intersection and the passage of the side road traffic will be influenced. In this paper, a coordinated control method based on the mixedlogicdynamic(MLD) model will be introduced using bi-level programming genetic algorithm to coordinately control the off-ramp and the downstream intersection. In bi-level programming, the first stage is acquisition of the best cycle length of the downstream intersection using genetic algorithm, and the second, the optimized result is considered as the initial condition to optimize the waiting time of the vehicles to obtain the best green-time of each phase. Compared with single-programming method, which will bring in errors because the cycle length of downstream intersection must be a known quantity, bi-programming optimization can avoid the problem. The control method is verified by road network simulation using VISSIM.
