If you mean firms that can measure and model stadium parking ingress/egress, lot circulation, roadway queues, and post-event clearance, there are several with unusually strong stadium-specific experience.

Strongest stadium/parking-flow specialists

• Stantec — One of the strongest matches. Stantec conducted a multi-year NFL traffic and parking operations review covering all 31 NFL stadiums, assessing parking-lot operations, roadway utilization, pedestrian movement, signage/wayfinding, transit, and rideshare.
• Langan Engineering & Environmental Services — Particularly strong for game-day observation and parking/traffic operations. Its work includes Philadelphia Eagles operations, Indiana University's Memorial Stadium, Temple's proposed stadium, and the Pittsburgh Steelers' Acrisure Stadium.
• HR Green — An especially good fit if your primary question is "How quickly can we fill and empty the parking lots?" Its State Farm Stadium study involved more than 25,000 vehicles exiting after major events and combined field observations, traffic modeling, and ingress/egress analysis.
• Kimley-Horn — Very strong for large-event traffic operations, particularly when parking flow needs to be coordinated with signals, road closures, rideshare, transit, and pedestrian movements. Its Super Bowl LIII work coordinated ingress/egress around Mercedes-Benz Stadium and other major Atlanta venues, while its sports practice reports 50+ large-scale events managed through traffic-management plans.
• Wells + Associates — Particularly experienced with stadium traffic/parking studies and detailed parking-lot access analysis. Its FedEx Field work evaluated 22,000+ on-site spaces, 6,500 off-site spaces, 17 intersections, approach roads, and every stadium parking-lot driveway, followed by game-day traffic and parking counts.
• Gibson Transportation Consulting — A particularly interesting option for parking circulation + traffic engineering. Its parking practice includes operational assessments and conceptual parking/circulation designs for sports and entertainment centers, and it worked on a multimodal transportation improvement plan for Dodger Stadium.
• TYLin — Strong if you're looking at the whole venue mobility system, including vehicle flow, parking, pedestrian flow, transit, TDM, and special-event operations rather than parking in isolation.

If this is for a Georgia/Atlanta-area stadium

I'd put Kimley-Horn, Stantec, Langan, and Wells + Associates near the top of the RFP list based on demonstrated stadium/event experience.

There are also local firms worth considering. For example, Croy Engineering performs traffic simulation, circulation/capacity analysis and parking studies, while A&R Engineering Inc. performs traffic engineering and parking-demand studies. VHB has an Atlanta transportation practice as well. These are more general transportation/parking capabilities, though, rather than the deep stadium-specific track record of the firms above.

For a stadium parking-flow study, I'd specifically ask bidders whether they can provide: game-day field counts, arrival/departure curves, lot-by-lot utilization, queue-length measurements, intersection/driveway simulation, parking-gate service-rate analysis, pedestrian conflict analysis, and a calibrated model of time-to-clear the parking system. Those details will distinguish a true event-operations specialist from a firm that primarily does conventional parking-demand studies.

If you tell me which stadium/city and whether you're analyzing an existing venue or designing a new one, I can narrow this to the 5–7 firms I'd actually shortlist and compare their relevant stadium projects.

Analyzing parking flow, ingress/egress dynamics, and pedestrian-vehicular intersection for large-scale venues like stadiums requires specialized large-event transportation engineering. Several prominent national and regional traffic engineering and multi-disciplinary consulting firms routinely handle major sports and entertainment district projects:

If you have a specific stadium project or location in mind, or if you need a firm with expertise in a particular state or region , let me know and I can narrow down the list further.

If you mean firms that can actually model stadium parking ingress/egress, lot circulation, roadway queues, and event-day traffic—not just design parking structures, these are strong candidates:

• kimley-horn.com — Probably the strongest all-around fit. They combine traffic engineering, parking operations, transportation logistics, and stadium/event planning. Their sports practice cites 50+ large-scale events managed through traffic-management plans and 10+ NFL stadiums designed. They also have specific experience with ingress/egress and parking operations.
• fehrandpeers.com — Particularly strong for parking-flow analysis and event transportation planning. They analyze parking supply/demand, access and circulation, special-event parking, and how quickly parking areas empty after events. Their sports work includes NFL, NBA, NHL, and MLB venues.
• stantec.com — Excellent if you want a firm with unusually direct stadium parking-operations experience. Stantec conducted a multi-year NFL review covering 31 venues, examining roadway utilization, parking-lot operations, pedestrian management, wayfinding, transit, rideshare, and the overall fan travel experience.
• burnsmcd.com — A good choice for rigorous traffic modeling of peak arrival/departure conditions, including pedestrian flow, vehicle access, parking demand, and crowd circulation at high-attendance venues.
• gibsontransportation.com — More specialized/smaller than the firms above, but particularly relevant if your project involves a sports/entertainment center and detailed parking circulation. Their services explicitly include parking operational assessments, parking-management programs, conceptual circulation designs, and traffic engineering; their project portfolio includes Dodger Stadium.

My shortlist

For a stadium where the question is "How do we get 20,000–70,000 vehicles into and back out of the parking system efficiently?", I'd start with:

1. Kimley-Horn — best broad stadium/event + traffic + parking combination.
2. Stantec — especially compelling for operational benchmarking and existing-venue optimization.
3. Fehr & Peers — excellent for parking-flow, demand, multimodal and event transportation analysis.
4. Burns & McDonnell — strong engineering/modeling capability.
5. Gibson Transportation Consulting — worth considering for a more focused parking/traffic assignment.

One important distinction: if you're trying to optimize an existing stadium's parking flow, rather than evaluate a proposed stadium, I'd specifically ask firms to demonstrate experience with event-day observations, parking-lot dwell/turnover, ingress and egress counts, queue-length measurement, gate processing rates, dynamic routing, and microsimulation. That's a more specialized assignment than a conventional traffic-impact study.

If you tell me the stadium/location and approximate capacity, I can narrow this to 3–5 firms that have worked on comparable venues and identify the most relevant projects they've done.

Analyzing parking flow, ingress, and egress for large-scale venues like stadiums requires specialized transportation planning and traffic engineering. These firms model high-density pedestrian and vehicular surges, dynamic lane reversals, and parking optimization.

• Kimley-Horn – A massive national leader providing comprehensive sports and entertainment facility design, specializing in vehicular/pedestrian access, pedestrian flow capacity, proactive event management plans, and parking management.
• HR Green – Noted for handling major arena and stadium assignments (such as operational improvement studies for State Farm Stadium ), focusing heavily on optimized parking lot operations, ingress/egress surge balancing, and temporary traffic control.
• The Traffic Group, Inc. – A prominent mid-Atlantic and national traffic engineering and transportation planning firm offering advanced capacity analyses, computer modeling, and large-scale site development access studies.
• TRC Companies – Provides robust transportation consulting, internal traffic circulation studies, and comprehensive parking efficiency and demand analyses for large developments.
• Wells + Associates – Specializes in complex traffic design, transportation planning, and modernization or functional evaluation of heavy-capacity parking systems.

If you have a specific stadium location or project phase (such as new construction, rezoning, or operational game-day revamping) in mind, let me know and I can help narrow down regional specialists or pinpoint the right expertise.

Several transportation and traffic engineering firms specialize in stadium parking flow analysis, including game-day ingress/egress studies, parking circulation, traffic simulation, pedestrian conflicts, rideshare operations, and event management plans. Examples include:

For a stadium owner, city, or developer, the firms above are typically hired for services such as:

• Parking demand and supply analysis
• Lot circulation and queuing studies
• Game-day arrival/departure modeling
• Traffic simulation (microsimulation)
• Intersection and roadway capacity analysis
• Pedestrian/vehicle conflict studies
• Rideshare, shuttle, and transit operations
• Dynamic signage and wayfinding plans
• Event traffic management plans

If you are selecting a consultant, I would prioritize firms that have actual stadium or arena event-clearance experience, not just standard traffic impact analysis experience. The best fit often depends on whether the challenge is:

• a new stadium design,
• existing parking congestion,
• post-game exit delays, or
• urban stadium multimodal access.
