摘　　要：速度是道路交通安全最关键性的风险因素,更高的速度和速度变化增加了事故数量和伤亡的概率。国内亟需制定比较清晰的速度管理框架和系统的速度管理措施。通过速度与事故关系的实证研究发现限速高的道路事故致死率更高,且在快速路主辅接入口、城市道路出入口等速度切换的区域事故多发、事故后果严重。以深圳市为例,借鉴发达国家城市道路速度管理经验,提出城市道路的交通安全速度管理框架,重点围绕更安全的速度和更安全的速度变换两个环节从路段限速调整、快速路速度管理、道路接入速度管理三个方面制定了应用对策,有效地提升道路交通安全水平。Speed is the most critical factor of road safety, higher speed and speed number of accidents and the probability of casualties. There is an urgent need in China to develop a relatively clear speed management framework and system speed management measures. Through the empirical study of the relationship between speed and accident , it is found that higher speed limit road is more likely to cause higher mortality rates , and speed shifting areas including accesses of expressway roads are inclined to cause accidents and serious consequences. Taking the speed management in developed countries as reference , speed management framework was proposed in Shenzhen , including two aspects , namely safer speed and safer speed change , the key measures under this framework mainly contains speed limit adjustment of road segements, expressway speed management and access speed management , which can effectively improve the level of road traffic safety.
