A-500 中清幹線

Abstract

中文摘要 本研究旨在探討台中市 500 路中清幹線公車系列路線之營運特性，針對現行營運因大客車駕駛員嚴重缺工所引發的班次脫班、減班及班距拉長等服務水準下降問題，提出具體可行之路線優化策略與政策建議。 研究過程運用 2024 年 500 路系列公車之電子票證大數據，導入 Excel 樞紐分析進行資料清洗、加總與排序，交叉比對各路線前十大上下車站點運量、起訖點（OD）矩陣圖 及尖離峰乘客時段分布；同時輔以隨車質性隨機觀測與利害關係人影響評估。 研究結果顯示，500 路主線目前已實質由 500 延代駛，且 500 延於端點及尖峰時段具高度穩定客源；跳蛙公車部分站點（如彰化銀行、天津路商圈等）其 OD旅次占比低於 10%且與鄰近大站步行距離僅 3 至 5 分鐘；500 延 3 於夜間離峰時段則存在大量空車及極低運量現象。據此提出三大結論：(1)將 500 延正名為 500路主線，確立高效率主線運輸定位；(2)剔除跳蛙公車 6 個低效且高替代性站點，預估可縮短車程 5 分鐘以上，提升行車速率；(3)將夜間離峰之 500 延 3 跨線整併至 500 延，重組無效運能。本成果可提供交通主管機關推動幹線公車聯營、班表整合及客運業者進行人力資源最佳化配置之參考依據。

Abstract This study investigates the operational characteristics of the Taichung City Bus Route 500 Zhongqing Corridor service network and examines the service challenges caused by the ongoing shortage of bus drivers, including reduced service frequency, missed trips, and longer headways. Based on these issues, the study proposes practical route optimization strategies and policy recommendations to improve operational efficiency and service quality. The analysis was conducted using the 2024 electronic fare collection data of the Route 500 bus network. Microsoft Excel PivotTables were employed for data preprocessing, aggregation, and statistical analysis. Passenger demand was evaluated through comparisons of the top boarding and alighting stops, Origin–Destination (OD) matrices, and peak- and off-peak travel patterns. In addition, on-board field observations and stakeholder analysis were incorporated to provide complementary qualitative evidence. The results indicate that the original Route 500 has effectively been replaced by Route 500 Extension, which demonstrates stable passenger demand, particularly at terminal sections and during peak hours. Several skip-stop stations on the Route 500 Express service, such as Changhua Bank and Tianjin Road Commercial District, account for less than 10% of total OD trips and are located within a three- to five-minute walking distance of nearby major stops. Furthermore, Route 500 Extension 3 experiences consistently low passenger demand and a high proportion of empty vehicle operations during off-peak evening periods. Based on these findings, three optimization strategies are proposed: (1) redesignating Route 500 Extension as the official Route 500 trunk service to establish a high-efficiency trunk bus corridor; (2) removing six low-demand and highly replaceable express stops to reduce travel time by more than five minutes and improve operational efficiency; and (3) integrating the evening off-peak services of Route 500 Extension 3 into Route 500 Extension to optimize resource allocation and eliminate redundant capacity. The findings of this study provide useful references for transport authorities in promoting trunk bus operations, coordinated route management, and more effective allocation of operational resources under driver shortage conditions.
