Impact of Access Density on Crash Risk After Controlling for Access Volumes
| 项目名称： | Impact of Access Density on Crash Risk After Controlling for Access Volumes |
| 摘要： | Past studies have reported that crash risk is affected by access density. However, these early access management studies that came to this conclusion may not have fully controlled for access volumes. It is possible that the factor driving crash risk is not access point density but rather higher volumes at cross streets, commercial driveways, or service roads. The aim of this research is to determine the true relationship between access density and safety while controlling for access volumes. The study will determine the extent to which recent access management studies have controlled for access volumes in analyzing crash risk and access density. If not, this effort will examine the relationship between crash risk, access density, and access volumes for one or more sample Virginia corridors. |
