摘要

通用交通接驳规范(GTFS)是一种数据格式,广泛用于共享公共交通时刻表数据和相关地理信息。GTFS 有两个版本:GTFS 静态版描述计划行程,GTFS 实时版描述实际行程。MobilityDB 是一个新颖、免费的开源移动对象数据库,作为 PostgreSQL 和 PostGIS 的扩展而开发,增加了空间和时间数据类型以及大量功能,便于分析移动数据。将 GTFS 数据加载到 MobilityDB 是一项相当复杂的任务,但必须以临时方式完成。本作品介绍了如何使用 MobilityDB 分析布宜诺斯艾利斯市的公共交通流动性,并同时使用布宜诺斯艾利斯公共交通系统的静态和实时 GTFS 数据。此外,还制作了可视化工具来增强分析效果。据作者所知,这是首次尝试使用移动对象数据库分析 GTFS 数据。

Analyzing public transport in the city of Buenos Aires with MobilityDB.

The General Transit Feed Specification (GTFS) is a data format widely used to share data about public transportation schedules and associated geographic information. GTFS comes in two versions: GTFS Static describing the planned itineraries and GTFS Realtime describing the actual ones. MobilityDB is a novel and free open-source moving object database, developed as a PostgreSQL and PostGIS extension, that adds spatial and temporal data types along with a large number of functions, that facilitate the analysis of mobility data. Loading GTFS data into MobilityDB is a quite complex task that, nevertheless, must be done in an ad-hoc fashion. This work describes how MobilityDB is used to analyze public transport mobility in the city of Buenos Aires, using both, static and real-time GTFS data for the Buenos Aires public transportation system. Visualizations are also produced to enhance the analysis. To the authors' knowledge, this is the first attempt to analyze GTFS data with a moving object database.

期刊介绍: The scope and purpose of the journal includes, but is not limited to, any type of research in the area of Public Transport: Planning and Operations. As its core it serves the primary mission of advancing the state of the art and the state of the practice in computer-aided systems and scheduling in public transport. The journal considers any type of subjects in this area especially with a focus to planning and scheduling, the common ground is the use of computer-aided methods and operations research techniques to improve information management, network and route planning, vehicle and crew scheduling and rostering, vehicle monitoring and management, and practical experience with scheduling and public transport planning methods. Besides theoretical papers, the journal also publishes case studies and applications. Public Transport addresses transport operators, consulting firms and academic institutions involved in development, utilization or research of computer-aided planning and scheduling in public transport.Officially cited as: Public Transp
