道路线形的安全评价是从设计阶段保证行车安全的关键,道路平曲线的弯曲程度直接影响着行车安全,单位交角曲线长L/I(曲线长/曲线交角)代表了道路平曲线的弯曲程度。通过大量的行车实验及驾驶员的心率、最高血压的变动与单位交角曲线长L/I的相关分析,结果表明单位交角曲线长L/I可作为道路平曲线设计要素的安全性评价指标。在线形复杂的山区公路,基于人机工程学与工程费用的考虑,行车安全需要的L/I取值应在0.5~1.0之间。 相似文献

随着汽车时代的到来,我国的道路交通形势越来越严峻,交通事故频发、交通秩序混乱、交通阻塞严重。为了探询能够尽快解开这一困局的方法,通过多年来对道路交通事故的成因进行深入地研究,分类分析,发现我国的道路交通事故70%以上、死亡人数的50%与行人和自行车有关。利用出国考察的机会,对欧洲及日本的道路交通及交通组织进行了认真的研究,并与我国的现实情况进行比较分析,因而得出:我国的道路交通问题关键出在道路的规划设计上,是由于在“混合交通”的理论基础引导下,使我国的道路在规划设计时就将交通特性完全不同的交通流混合在了一起,因而造就了目前这种“混合”、混乱的局面。只有确立道路交通安全第一的指导思想,建立交通分离的道路规划设计规范,修建出能够使行人、自行车远离机动车流且畅通、无障碍的道路系统来,达到各行其道有其道、各自愿行其本道良好交通道路条件,我国的道路交通将与发达国家的道路交通没有本质的区别,能够组织的一样好。我相信在不久的将来,我国的道路交通也会像一些发达国家那样安全、有序、畅通。 相似文献

以交通事故的诱发机理作为着眼点进行研究,指出不良的道路条件是引发道路交通事故的重要原因。结合国内外的研究结果,分析了道路条件对道路交通安全的影响。根据我国目前道路设计中对交通安全重视不足的现状,借鉴国外成功经验,提出了道路的规划设计不仅要满足基本的力学要求,更要保证道路交通安全的思想。 相似文献

This paper presents the historical and cultural background relating to road improvement and road safety characteristics in Kenya, a developing country in East Africa. Some who come from low-developed areas of developing countries often take time to comprehend the modern transportation infrastructure, especially roads, and have difficulty assimilating and customizing the same to their culturally tailored modes.This paper discusses two case studies: one on the socio-economic impact following improvements to a 50-km, high-class, high-traffic-volume road and the other on the monitoring and evaluation of road safety aspects along the Northern Corridor in Kenya also following major road improvements.The road improvements to the Nairobi-Thika Highway (a trunk road) have attracted many investors along the highway corridor. The high-speed road has also brought with it the unfortunate consequence of speeding vehicles colliding with pedestrians crossing the road at undesignated locations.The Northern Corridor, the transportation corridor that links the Great Lakes Countries of the Democratic Republic of Congo, Burundi, Rwanda, and Uganda from the port of Mombasa in Kenya, has had high accident rates for a considerable amount of time. The results of monitoring and evaluation exercises on the Northern Corridor have shown that drivers are the major contributors in causing accidents, with a component ratio of 49.4%; pedestrians are next at 21.7%. Data also shows that 24% of the accidents along the Northern Corridor are fatal, which is of major concern. The study additionally indicated that the majority of road users have not been exposed to education or training on road safety.This paper presents a number of recommendations arising from the road safety study regarding possible improvements in aspects of road safety along the corridor and potential applications of those changes to other roads in general. For example, there are recommendations related to the geometric design of the road, driver training and behavior, vehicle maintenance, and the need to enhance road safety through the utilization of road safety parks where road users can undergo training and drills on road safety aspects.In conclusion, we argue that the rehabilitation of the Northern Corridor from Mombasa on the Kenyan coast to the border with Uganda has led to significant road safety improvement. 相似文献

This paper deals with the fundamental research related to a new sensing system for road surface as the first step to construct an identification tool for the friction coefficient of the road ahead. In this paper, the albedo value is used for the measurement. Because the previous albedo meter measured the road surface by using sunlight, it was not used at night. Therefore, we propose a vehicle-mounted road surface sensing system by using a pair of solar cells with an additional light. From the experimental results, it is shown that the sensing system can measure the difference of road conditions, not only during daytime but also at night. For high reliability of detection, an image processing system of the road surface is proposed. It is shown that the sensor fusion can recognize the difference of the road surface. 相似文献
