金华市公交车路线调度预警分析数据
收藏资源简介：
通过金华市公交集团的指挥调度监控系统，收集公交车辆的烂班车辆调度数据，分析不同线路的烂班占比情况，为公交线路的烂班预警研判提供数据支撑，为提升运营管理效率提供有力的抓手。1、数据采集：通过金华市公交集团的指挥调度监控系统采集公交车辆的烂班班次、烂班类型等信息； 2、数据处理：对采集到班次数据进行汇总分类，剔除无效和错误数据，确保数据完整性和一致性； 3、数据加工：计算某一公交单程线路的烂班累计数量=所有烂班类型的次数合计∑Rk（k为不同烂班类型，k=1,..,n）；计算该路线所属车队的烂班次数合计∑Ri（i为不同路线，i=1,..,m）；计算某路线的烂班次数在车队中的占比=∑Rk/∑Ri，根据占比数值的大小判断预警等级，占比超过5%为重度预警；占比小于5%为轻度预警。 4、数据应用：结合地图工具将不用线路的预警等级进行分级展示，便于精准化管理不同预警等级的路线。
This dataset is sourced from the Command, Dispatch and Monitoring System of Jinhua Public Transport Group, which collects bus service delay (colloquially referred to as "lanban" in Chinese) scheduling data. It analyzes the proportion of delayed trips across various bus routes, providing data support for early warning and risk assessment of bus service delays, and offering a robust means to enhance operational management efficiency. 1. Data Collection: Collect data including delayed bus trip records and types of service delays via the Command, Dispatch and Monitoring System of Jinhua Public Transport Group. 2. Data Processing: Summarize and categorize the collected trip data, remove invalid and erroneous records to ensure data integrity and consistency. 3. Data Calculation and Enrichment: - Compute the cumulative number of delayed trips for a single bus route: total count of all delay types, denoted as ∑Rk (where k refers to different delay types, k=1,…,n); - Compute the total number of delayed trips for the fleet that the target route belongs to: ∑Ri (where i refers to different routes, i=1,…,m); - Calculate the proportion of delayed trips of a specific route in its affiliated fleet: ∑Rk / ∑Ri. Determine the early warning level based on this proportion: severe warning if the proportion exceeds 5%, and mild warning if the proportion is below 5%. 4. Data Application: Integrate with mapping tools to visually present the warning levels of different routes in a graded fashion, enabling precise management of routes corresponding to different warning levels.
