FLOW™ Overview
FLOW™ - Airport Terminal Planning
Smarter Terminal Capacity Planning from Curb to GateAVIAS™ FLOW™ is a comprehensive, spatial demand and capacity planning application designed specifically for airport terminals. From curbside check-in to gate hold areas, FLOW™ delivers detailed insight into infrastructure needs and level-of-service performance across all components of the terminal environment.
Built on Industry StandardsWhat sets FLOW™ apart is its integration of industry standards and planning guidelines from leading authorities including the FAA, TRB/ACRP, TSA, CBP, IATA, ICAO, and ADA. These references are seamlessly embedded into the application’s engine—no need to manually cross-reference spreadsheets or PDFs.
Intuitive Interface, Immediate ResultsSay goodbye to sprawling, error-prone spreadsheets. FLOW™ uses a flow-based, graphical user interface (GUI) designed for planners, by planners. Users can quickly assess time-based scenarios, analyze future activity levels, model planning triggers, and instantly see results - no complex coding or manual recalculations required.
Powerful Scenario PlanningWhether you’re assessing the impact of aircraft fleet changes, up-gauging of aircraft types, or adding new demand, FLOW™ delivers immediate clarity:
- Determine gate and holdroom requirements
- Identify restroom and concession space needs
- Evaluate TSA checkpoint lanes and queue areas
- Test scenarios against Level of Service (LOS) targets using our stoplight-style optimization matrix
FLOW™ enables airport operators and planners to make confident, data-driven decisions about terminal development and space allocation. With its real-time analysis capabilities, FLOW™ answers the “what if” questions in seconds—empowering faster, smarter terminal planning from day one.
