Use Of Harsh-Braking Data From Connected Vehicles As A Surrogate Safety Measure, Nathaniel Patrick Edelmann
Use Of Harsh-Braking Data From Connected Vehicles As A Surrogate Safety Measure, Nathaniel Patrick Edelmann
Boise State University Theses and Dissertations
Traffic safety may be analyzed with the use of surrogate safety measures, measures of safety that do not incorporate collision data but rather rely on the concept of traffic conflicts. Use of these measures provides several benefits over use of more traditional analysis methods with historical crash data. Surrogate measures eliminate the need to wait for crashes to occur to conduct a safety analysis. The amount of time required for enough crash data to accumulate can be significant, delaying safety analyses. Similarly, these measures allow for safety analysis to be conducted prior to crashes occurring, potentially calling attention to hazardous …
