摘　　要：考虑站点设施分布组合情况、设施开放时间和最小活动时间以及乘客访问设施路径等因素,对现有的时空效用计算方法进行改造,使之适用于个体公交出行的时空效用计算。以广州市北京路商业中心区为研究区域,分析了乘客出发时刻、出行时间预算,站点服务范围等时空约束下的时空效用变化情况,发现该方法能客观准确地反映时空约束带来的可达性变化,能用于指导个体实现精确出行。Considering the distribution and combination of station facilities, the service time of facilities, the minimum participation time as well as the passenger access path to facilities, the current space-time benefit calculation approaches were innovated to be fit for the space-time benefit calculation for the individual to take public traffic. Taking the commercial center of Beijing Road in Guangzhou as a research object, the changes of the space-time benefits were analyzed under spacetime constraints, including the departure time, the travel time budget and the service range of facilities. It is found that the proposed method can accurately reflect the changes of accessibility brought by space-time constraints, which can be used to guide the individual to achieve precise travel.
