Abstract

Due to the economic and social cost of traffic accidents, it is essential for road administrators to properly evaluate where infrastructure investments are necessary to improve the system. Network Safety Management (NSM) is an analysis tool typically used on freeways and other interurban roads to identify the locations with the highest potential for infrastructure improvements from a safety perspective. In this paper we investigate how this tool can also be used to identify such locations within an urban environment.

The aim of this research is to investigate the application of NSM in urban environments, illustrate it with real case studies, evaluate the results obtained, and test their robustness for different input parameters.
