Traffic engineering solutions cannot be designed in a vacuum, and the most effective solutions occur when there is a seamless integration of the design and transportation analysis process.

For more than 80 years, WSP SELLS has fostered this interactive approach on all of their highway, bridge and development projects.

WSP SELLS has the ability and experience to analyze all modes of transportation through the latest modeling technology in traffic, rail, pedestrian, and multi-modal operations. At the cutting edge of transportation technology, WSP SELLS can bring all of these disciplines together in a design that moves people safely and efficiently, while still respecting the character of the project surroundings.
