Dawood has transformed the way we present our findings for Road Safety Audits (RSA) by integrating GIS technology into the process. Interactive Story Maps and Operations Dashboards were used during recent RSA meetings with local, state, and federal offices in PennDOT’s District 8-0 to examine the roadways. Story Maps are interactive, engaging web applications that allow users to customize various content – text, images, videos, and immersive maps – into a variety of templates. A tabbed Story Map was used for these meetings to step the audience through the process. Tabs included information such as a project overview, limit and operational characteristics, an overview and video of the Federal Highway Administrations RSA process, interactive mapping, and daytime and nighttime videos of the route in focus.
Operations Dashboards are a configurable web application that displays data dynamically through various summary widgets. We displayed crash data for the previous 5 years along with each road segment. As the extent of the map changed, widgets summarizing the collision type, weather conditions, time of day, and other relevant statistics updated as well. This interactivity enabled an immersive discussion amongst key players.
These products received praise from the Federal Highway Administration for their ease of use and presentation of material.
What is a Road Safety Audit (RSA)?
Per the Federal Highway Administration, ‘A Road Safety Audit (RSA) is the formal safety performance examination of an existing or future road or intersection by an independent, multidisciplinary team. It qualitatively estimates and reports on potential road safety issues and identifies opportunities for improvements in safety for all road users.’
What are the benefits of a Road Safety Audit?
May help produce designs that reduce the number and severity of crashes
May reduce costs by identifying safety issues and correcting them before projects are built
Promote awareness of safe design practices
Integrate multimodal safety concerns
Consider human factors in all facets of design
