| abstract: |
|
The dissertation included three scientific studies. Data from the respective offices
on crashes, traffic and the geometric design of roads were obtained. To examine the
spatial patterns of Crashes and identify crash hotspots in Ethiopia, the spatial autocorrelation
of crashes and Getis-Ord-Gi* statistics in ArcGIS were used. Moreover, the Crash Prediction
Model of the Highway Safety Manual and Interactive Highway Safety Design Model has
been exploited to evaluate the safety performance of rural roads and quantify the
safety effects of road design improvements made to existing roads

Die Dissertation umfasste drei wissenschaftliche Studien. Von den zuständigen Ämtern
wurden Daten über Unfälle, Verkehr und die geometrische Gestaltung von Straßen eingeholt.
Um die räumlichen Muster von Unfällen zu untersuchen und Unfallschwerpunkte in Äthiopien
zu identifizieren, wurde ArcGIS verwendet. Das Crash Prediction Model des Highway
Safety Manual und das Interactive Highway Safety Design Model wurden genutzt, um die
Sicherheit ländlicher Straßen zu bewerten und die Sicherheitsauswirkungen von Verbesserungen
der Straßengestaltung bestehender Straßen zu quantifizieren.
