Abstract High budget transport infrastructure projects in the Istanbul Metropolitan Area endeavour to increase the efficiency of the transportation system. Among those investments; the bus rapid transit system – Istanbul Metrobus Line (IML) – is the most popular one that serves one million trips per day. Yet, the performance and impact of IML are not quantitatively assessed. Hence in this study, a high-resolution GIS-remote sensing framework is designed to analyse before and after accessibility over the period of 40 years (namely 1987–1997–2007–2014). High resolution satellite images were processed to generate the lacking historical land cover/use information with the expected high accuracy. Within the study area, utilized accessibility indices have unevenly increased after the operation of IML, such as 104.19% in potential and 99.07% in daily accessibility. According to the achieved results, such high spatio-temporal spatial framework could aid decision makers to quantitatively assess and evaluate the performance of such investments.

伊斯坦布尔地铁公交线路交通可达性时空评价

摘要 伊斯坦布尔都市区的高预算交通基础设施项目致力于提高交通系统的效率。在这些投资中；快速公交系统 – 伊斯坦布尔地铁 (IML) – 是最受欢迎的系统，每天服务 100 万人次。然而，未对 IML 的性能和影响进行定量评估。因此，在本研究中，高分辨率 GIS 遥感框架旨在分析 40 年（即 1987-1997-2007-2014）期间可访问性之前和之后。处理高分辨率卫星图像以生成具有预期高精度的缺乏历史土地覆盖/使用信息。在研究区内，IML运营后的利用可达性指数增长不均，潜力为104.19%，99. 07% 的日常可访问性。根据取得的成果，这种高时空空间框架可以帮助决策者定量评估和评估此类投资的绩效。
