TSI provides specialized consulting services that can range from a simple traffic impact analysis for a small commercial development to environmental impact statements for the phased development of a medical center or University. Design services focus primarily on roundabout and signalization designs for intersections as well as review of roadway designs for our civil engineer colleagues. In addition, community groups, institutions, and businesses frequently partner with TSI for assistance in developing solutions for traffic safety, access, special event, or other concerns that require team members to develop creative solutions to complex problems.
