With a rapid development of Bus Rapid Transit (BRT) system in China, many studies on planning and design of BRT have been conducted; however, there is only little research on the feeder system of the BRT system, especially for the layout of the newly added feeder lines. In this paper, we first put forward that the reasonable influence area of BRT and the layout of feeder lines should be determined on the basis of questionnaire surveys of passengers close to the BRT stations. Second, the selection principle of newly added feeder lines and the feeder stops were proposed. Then, a mathematical model with the connection benefits (including travel time cost and operation cost) as a minimum objective function has been conducted for the first time, an improved genetic algorithm was designed to calculate the model, and the layout scheme of newly added feeder lines was solved. Finally, the methodology was applied to the case of Beijing BRT line 1. With the goal of 80% passengers' interest, the reasonable influence radius of Beijing BRT line 1 is 3.89 km. After the calculating the model, eight newly added feeder bus lines were designed linking to the Beijing BRT line 1. The results reveal that the layout method of newly added feeder bus lines coordinating with BRT can be well used to support the feeder system design of Beijing BRT.
