Analysis Of Safety Impacts Of Access Management Alternatives Using The Surrogate Safety Assessment Model, Kyung Min Kim
Analysis Of Safety Impacts Of Access Management Alternatives Using The Surrogate Safety Assessment Model, Kyung Min Kim
Theses and Dissertations
In a traditional safety impact analysis, it is necessary to have crash data on existing roadway conditions in the field and a few years must pass before accumulating reliable crash data. This is a time-consuming approach and there remains uncertainty in the crash data due to the random nature of crash occurrences. The Surrogate Safety Assessment Model (SSAM) was developed for resolving these issues. With SSAM, a conflict analysis is performed in a simulated environment. A planned improvement alternative under study is modeled and no physical installation of the alternative is needed. Hence, the method using a simulation software along …

Using Lidar Data To Analyze Access Management Criteria In Utah, Marlee Lyn Seat
Theses and Dissertations
The Utah Department of Transportation (UDOT) has completed a Light Detection and Ranging (LiDAR) data inventory that includes access locations across the UDOT network. The new data are anticipated to be extremely useful in better defining safety and in completing a systemwide analysis of locations where safety could be improved, or where safety has been improved across the state. The Department of Civil and Environmental Engineering at Brigham Young University (BYU) has worked with the new data to perform a safety analysis of the state related to access management, particularly related to driveway spacing and raised medians. The primary objective …
