Abstract |
The restriction problem of public bicycle system (PBS) development is scheduling delay, so that its service level cannot meet users' demand. From aspects of time and spatial distribution, the relationship between demand pattern and land type of public bicycle station is analyzed. A multilevel partition scheduling method is creatively proposed which is divided into three levels: upper-level scheduling region, scheduling cell and PBS station. Based on the detailed analysis of the hierarchical partitioning process and related parameters, a multi-objective optimization scheduling model with time window combined with virtual cell is presented to solve the problem of inter-cell scheduling. And also the optimal path model of scheduling within cell is built. The pattern of inter- cell flexible scheduling and inner- cell semi- deterministic scheduling is formed. The case study shows that the method is workable. It is significant in reducing the blindness and improving scheduling efficiency, as well as decreasing unnecessary time of detour and congestion and ensuring the timely scheduling during peak hours.
