NIGP 92593: Traffic and Transportation Engineering

NIGP 92593 Traffic and Transportation Engineering, an Item code, encompasses traffic signal design, roadway and intersection traffic analysis, traffic control planning, and transportation engineering studies that state and local governments buy to manage traffic safety, signal coordination, and multimodal connectivity across their networks. Recent activity shows state and local jurisdictions using this code for design of traffic signal modernization, intersection improvements tied to pedestrian safety initiatives, toll collection system upgrades, and comprehensive safety planning under federal Safe Streets and Roads for All grant programs.

The issuing-body mix spans county public works departments, city transportation and engineering divisions, county and regional transit authorities, and special-purpose water districts. The County of Orange (California) and Orange County Flood Control District appear repeatedly across multiple solicitations for traffic engineering and transportation design support on task-order basis. Geographic spread centers on California, Georgia, Florida, Texas, and Arizona, with activity spanning county governments, mid-size cities, and state DOT coordination across the Southeast and Southwest. Representative recent opportunities include the City of Orlando's RFP for a Red-Light Camera Traffic Infraction Detector System covering 80 intersections (proposals due September 17, 2026); the County of Orange's RFQ for land surveying services spanning records research, GNSS surveys, and topographic surveys supporting traffic and transportation projects (due July 21, 2026); Cameron County's solicitation for traffic signal improvements under a Carbon Reduction Program with GPS-based synchronization equipment (due July 28, 2026); and Bryan County Board of Commissioners' request for planning services to develop a Safe Streets and Roads for All Safety Action Plan (due August 14, 2026). Across these opportunities, compensation is typically time-and-materials or fixed-price based on detailed scope, with three-year base terms and renewal options common in on-call QVL structures. California prevailing wage requirements and federal compliance (FAA, FTA, FHWA standards) apply to most federally funded work; small business participation goals and DBE set-asides appear in several California and Georgia solicitations.
