ChinaRAP Project Snapshot 1: Improve Highway Safety to Cherish the Life Project (HSEP 2)
• HSEP 2 focuses on:
– scope of project: improving infrastructures on expressway, national and provincial trunk roads, and rural roads
– total investment(estimated): 120 billion CNY
– type of roads: existing roads, new built roads, and reconstructed roads.
– principles and countermeasures
• principle 1: Existing roads - Eliminating the current hazardous road sections
• principle 2: New-built roads - no more new hazardous roads should be added
during the designs and constructions stage
• countermeasures: Decision making process changes: single-index based method to ChinaRAP.

• More than 100,000km National and provincial roads in Beijing Shandong Guangdong Jilin
Hubei Henan Chongqing Fujian Zhejiang Guizhou Yunan XinJiang were assessed.
• More than 100 staff take part in the survey
• More than 300 take part in the coding and quality checking

S206(荣合路)K115.6——K115.5路段
该路段为非分隔式山区车道穿村镇路段,路侧干扰较多,为Y交叉口。该位置转弯
半径较小,路侧有水塘,且无防护设施。当前限速40km/h,提高限速后风险增加
,不建议提高车速。
