【摘要】：為有效控制道路交通事故的發(fā)生,基于風(fēng)險對我國道路限速標(biāo)準(zhǔn)進(jìn)行科學(xué)設(shè)計(jì),將敏感性因素引入風(fēng)險的概念中,從安全事故產(chǎn)生的可能性、嚴(yán)重性和敏感性3個維度構(gòu)建道路風(fēng)險分級三維評價模型,以3個維度為一級指標(biāo)建立道路風(fēng)險評價指標(biāo)體系,最終形成道路風(fēng)險分級評價方法,基于道路風(fēng)險等級科學(xué)確定限速標(biāo)準(zhǔn),將安全性與經(jīng)濟(jì)性有效結(jié)合。以北京市四環(huán)某路段為例,提出道路單元劃分原則,用所構(gòu)建的道路風(fēng)險分級評價方法對該路段進(jìn)行評價并優(yōu)化設(shè)計(jì)其限速標(biāo)準(zhǔn),驗(yàn)證了方法的可行性。
[Abstract]:In order to effectively control the occurrence of road traffic accidents, the road speed limit standard is designed scientifically based on the risk, and the sensitivity factor is introduced into the concept of risk, from the possibility of safety accidents. Three dimensions of the severity and sensitivity of road risk classification three-dimensional evaluation model, with the three dimensions as the first level indicators to establish the road risk evaluation index system, and finally formed the road risk grading evaluation method. Based on the scientific determination of the speed limit standard of road risk grade, the safety and economy are effectively combined. Taking a certain section of the fourth Ring Road in Beijing as an example, the principle of road unit division is put forward. The feasibility of the method is verified by evaluating the road section and optimizing the design of the speed limit standard by using the road risk grading evaluation method.
