We provide a smartphone-based solution that can be installed in your agency fleet vehicles to crowdsource sensor data which can be used to evaluate curve field safety conditions and determine the proper advisory speed.

Using only your roadway centerline shapefile, we’re able to accurately locate all curves of different types on your network and extract their geometrical features such as radius, point of curve, point of tangent, degree of curvature.

We can determine the appropriate curve warning signs to be installed on your network and that are compliant with the MUTCD 2009 requirements. User-friendly outputs including reports and GIS shapefiles can be delivered.

We can inventory all the existing curve warning signs on your roadway network and compare those to the generate MUTCD-compliance curve sign design to easily determine the need for sign improvement.

We provide a web-based tool that manages all your curve inventory in one-place, and integrates other data sources such as crash data to support curve safety analyses that determine and prioritize proper countermeasures on your network.
