Assessing the Safety Issues Associated with Isolated Rural Intersections
| 项目名称： | Assessing the Safety Issues Associated with Isolated Rural Intersections |
| 摘要： | Due to the relatively low traffic volumes on many rural high-speed roadways roads, it is often not cost-effective to upgrade the roads and not warranted to implement active traffic control devices such as traffic lights to improve safety at intersections and sometimes it may be even counterproductive. However, vehicles traveling on these roadways generally have high speeds and, thus, tend to have relatively more severe injuries when vehicle crashes do occur. In addition, many rural roadways also have high truck volumes and suffer from truck-related safety issues. Although local communities with problematic isolated intersections request traffic signals be installed, often these intersections do not meet the Texas Manual on Uniform Traffic Control Devices (TMUTCD) traffic signal warrants. Furthermore, the placement of a traffic signal at an isolated signal can also create a driver expectancy issue for the traveling public. The purpose of this research is to compile crash and operational data and perform a comprehensive assessment of the risk factors and root causes of crashes involving rural intersections, prioritize the risk factors, identify and evaluate safety countermeasures, and recommend the most effective, low-cost countermeasures for safety promotion. |
