Traffic safety is one of our core practice areas, our staff has co-authored the first edition of the Highway Safety Manual (HSM) published by AASHTO in 2010. Our staff has also supported local agencies in the implementation of the HSM methodologies through training and pilot projects. We have the expertise to work side by side with public and private clients transferring our knowledge and experience to develop a collaborative approach that leads to safer solutions. At the state level we have authored applications guide manuals tailored to local conditions and have worked with state agencies through the implementation of predictive traffic safety.
