Yes. Our transportation practice serves both sides of the table. We work with state DOTs, counties, and municipalities on corridor improvements, signal systems, and safety upgrades, and we support private developers with traffic impact studies, highway access permitting, and expert testimony for projects ranging from shopping centers and restaurants to industrial and warehouse facilities.

An adaptive signal system adjusts signal timing in real time based on actual traffic conditions rather than relying on pre-set timing plans. These systems improve traffic flow, reduce congestion, and can significantly cut delay times at intersections. Our team specializes in the design and optimization of adaptive systems and can help agencies determine where they will deliver the greatest benefit.

A traffic impact study analyzes how a proposed development will affect traffic operations on surrounding roadways. Most municipalities and DOTs require one when a new project is expected to generate a significant number of vehicle trips. Our planners prepare comprehensive studies that assess intersection capacity, signal timing, access points, and any improvements needed to maintain acceptable levels of service, and we provide expert testimony to support approvals when needed.

We conduct roadway safety audits and apply Vision Zero principles to identify locations where design changes can reduce the frequency and severity of crashes. That can include intersection reconfiguration, improved pedestrian crossings, signal upgrades, enhanced signing and pavement markings, and ADA curb ramp design. Our recommendations are driven by crash data and field observation, not assumptions.

Traffic engineers focus on the design and operation of specific systems like signals, intersections, and ITS infrastructure. Transportation planners take a broader view, analyzing how development, land use, and policy decisions affect mobility across a network. Our team includes both, and having them work together means projects benefit from detailed technical design and big-picture strategic thinking at the same time.

Yes. We develop maintenance and protection of traffic (MPT) plans that keep roadways safe and functional while construction is underway. These plans address lane closures, detour routes, temporary signage, pedestrian access, and phasing sequences, all designed to minimize disruption to the traveling public while giving contractors the access they need to get the work done.
