Assessment on the Impacts of Geometric Design on Road Safety

Road transport plays a vigorous role in the life of an individual socioeconomically. In order to have a normal traffic flow, road engineers must have to give priority to safety in their design such as consistent geometric design. In addition to driver error, roadway factors and the combined driver error and inconsistent geometric design are the major contributors to road safety issue. For a long period of time, road safety analysis was carried out with a traditional technique of sliding scale analysis. Which have drawbacks of incapability of using the latest technologies and also, tedious and unclear data acquisition and analysis. But, in this book the latest technique of using Geographical Information System (GIS) have been adopted for road safety analysis. Basically, the application of ArcGIS software has been implemented for the detection of crash intensive prone locations and identification of inconsistent geometric design segment of the road. In this book, Crash Hot-Spot locations and inconsistent geometric design segments of the road had been merged together to analyze the impacts of geometric design on road safety.
