摘要

本研究使用UIC 406方法和时间表规划质量评估来检验泰国南部铁路线在混合交通条件下的运营效率。这条走廊将电动通勤列车和长途列车整合在共享轨道上,采用不同的控制系统和街区配置。分析表明,基础设施设计,特别是块长度和信令,显著影响轨道利用率。本研究的一个重要贡献是将UIC 406压缩与旅行时间商(TTQ)整合在一起,以揭示时间表结构的低效率。研究结果表明,尽管列车量较大,但较短的街区支持更高的吞吐量,而较长的街区在列车较少的情况下导致更高的入住率。该研究提出了有针对性的改进措施,如细分街区和调整不同列车类型的时间表。这些措施可以在不需要新建轨道的情况下提高效率。研究结果为基础设施规划和政策制定提供了实践指导,为提高复杂混合交通条件下的走廊性能提供了可复制的方法。

Mixed railway operations on the southern line of Thai railways: track utilization efficiency analysis
This study examines the operational efficiency of Thailand’s Southern Railway Line under mixed-traffic conditions using the UIC 406 methodology and Timetable Planning Quality evaluation. The corridor integrates electric commuter and long-distance trains on shared tracks with different control systems and block configurations. The analysis shows that infrastructure design, particularly block length and signaling, significantly influences track utilization. A key contribution of this study is the integration of UIC 406 compression with travel time quotient (TTQ) to reveal inefficiencies in timetable structure. Findings indicate that short blocks support higher throughput despite greater train volumes, while long blocks lead to higher occupancy rates with fewer trains. The study proposes targeted improvements such as subdividing blocks and aligning timetables across train types. These measures can enhance efficiency without requiring new track construction. The results provide practical guidance for infrastructure planning and policymaking, offering a replicable approach for enhancing corridor performance under complex mixed-traffic conditions.
