Description
Summary:Coordination control is implemented on the main public transport system to reduce delay and improve the operation efficiency of buses on urban arterial roadways. First, the concept of a dual-loop phase is introduced and a new phase structure and sequences are proposed. Then, optimization models of the common signal cycle and effective green light time are built. Second, a genetic algorithm is used to optimize signal offset in coordination control according to the driving characteristics of a bus. To evaluate the effect of coordination control, a delay function is established to describe the control effect according to theory of triangle delay. Finally, the main arterial road is selected for a case study. The main parameters, such as common signal cycle, effective green light time, and offset, are optimized using Lingo and MATLAB. Results show that the bus delay value tends to decline after implementing the algorithm and the 50th iterative optimization result is 20.13% lower than that of the first iteration.
