邯长线扩能改造方案分析研究

既有邯长线1984年初全线建成开通,由于线路技术标准低,年运输能力小,1999--2001年进行了一次扩能改造,但仍满足不了晋煤外运的需要,需再次进行扩能改造。此文根据邯长线的地形地貌特点,对全线电气化改造方案、部分列车牵引5000t延长车站到发线方案、局部区段增建二线和新建双线取值方案进行分析与研究,经过论证和投资比较,扩能改造确定采用全线电气化、部分列车牵引5000t和9个车站到发线延长1050m、分段增建二线及线路坡度维持既有不变的方案。     

Evaluating safety effectiveness of roundabouts in Abu Dhabi

With more than 460 roundabouts located in Abu Dhabi, the capital city of the United Arab Emirates, it is imperative to evaluate the safety benefits provided by those roundabouts. In this study, two approaches were used to evaluate those safety benefits. The first approach is by measuring the 85th percentile operating speeds at a sample of 18 roundabouts in Abu Dhabi to determine whether the measured operating speeds conform to what is recommended by design guides. The second approach is by using a questionnaire to measure how drivers in Abu Dhabi perceive safety when driving at roundabouts and to measure their level of knowledge regarding the rules pertaining to driving at roundabouts. The study found that operating speeds at Abu Dhabi roundabouts typically exceed those recommended by design guides. The study also found that only 4.1% of the drivers interviewed demonstrated a comprehensive understanding of the rules pertaining to driving at roundabouts. Ordinal regression modeling was used to identify driver groups in need for more awareness of the rules to negotiate roundabouts in Abu Dhabi. The study found that the driver group in most need for more awareness is typically young and middle-age male drivers (below the age of 46?years) with less driving experience in countries where roundabouts are common. The questionnaire also revealed that despite the operational benefits provided by roundabouts (in terms of reduced delay), drivers do not prefer to drive at Abu Dhabi roundabouts, which might be explained by drivers' perception of Abu Dhabi roundabouts being not safe.
