Transportation Design

Matrix brings many years of experience designing transportation facilities, including roadways, intersections, corridors, and roundabouts.

Matrix has design expertise in multiple roadway types (local streets, collectors, arterials, highways) and intersections (stop-controlled, signal-controlled, roundabouts). We have prepared many plan, specification, and estimate (PS&E) packages that have been successfully constructed with minimal change orders and within project budgets and schedules. Further, most designs require the coordination of property and business owners, utility companies, and multiple agencies; our team is adept at the inter-stakeholder communication, organization, and relationship building needed for the successful design and realization of desired facilities.
