| Summary: | The traditional bus bay stops are prone to ponding, with reduced waiting comfort, low traffic efficiency and easily damaged pavement structure. Given the problem, based on the sponge design of the bay stop in northern China, the rainstorm flood management model under the traditional and sponge modes is constructed, and the runoff condition of the bus stop is analyzed. The results show that the combination design of LID facilities, such as permeable pavement and the recessed green belt has a good control effect on rainwater runoff in the stop section. The larger the range of LID measures adopted in the stop section, the more pronounced the runoff control effect. The combined design of sponge facilities can effectively control rainwater runoff. However, with the increase in rainfall intensity, the control effect of sponge measures on rainwater runoff at the bus stop gradually decreases.
