摘要:
［目的］随着麦加朝觐客流的逐年增长，麦加轻轨繁忙时段运行方案的通过能力达到饱和。为此，探究虚拟编组技术对麦加轻轨繁忙时段运行模式的优化效果，以提升其通过能力。［方法］在研究过程中，通过对发车间隔和发车顺序的深入分析，构建了开行方案。在不同时段采用了A—E共计5种运行模式，以繁忙时段(运行模式C)内总开行列车数最多为目标，运用运行图周期分析方法，得出了最优的运行方案。［结果及结论］研究结果表明，采用虚拟编组技术优化后的运行方案相较于既有的繁忙时段运行方案，能够压缩部分列车发车间隔时间，从而提升运行图周期，进而提高通过能力。虚拟编组技术的应用使得在繁忙时段(5h)内能够开行144对列车，相较于原有模式的132对，通过能力相对提升了9.1%。该研究的实际意义在于为麦加轻轨提升通过能力及服务水平提供了现实可行的方案。

［Objective］ With the annual increase of pilgrim flow in Mecca, the throughput capacity of Makkah Metro Pink Line (simplified as Mecca light rail) operation plan during peak hours is saturated. Therefore, it is aimed to explore the optimization effect of virtual formation technology on the operational mode of Mecca light rail during peak hours, targeting at improving its throughput capacity. ［Method］ In the research process, an operation plan is constructed through in-depth analysis of departure intervals and sequencing. Five operational modes, denoted as A to E, are adopted for different hours. With the objective of maximizing the total number of trains operated during peak hours (operational mode C), the optimal operation plan is obtained using timetable cycle analysis method. ［Result & Conclusion］ Research results indicate that the operation plan optimized with virtual formation technology, compared to the existing plan for busy hours, can compress the departure intervals of some trains, thereby improving the timetable cycle and consequently enhancing throughput capacity. The application of virtual formation technology allows for the operation of 144 pairs of trains during busy hours (about 5 hours), demonstrating a relative increase of 9.1% in throughput capacity compared to the original mode of 132 pairs. The practical significance of the research lies in providing a realistic and feasible solution for enhancing the throughput capacity and service level of Mecca light rail.
