Stress-Testing Success: Why Every Major Event Travel Demand Management Programme Needs a Live Test Event

Testing and readiness is integral
Every major event transport plan looks convincing on paper. The modelling holds up, the messaging is agreed and the partners have signed off. Then 80,000 people try to get home at once, and organisers find out what actually works.
Transportation demand management (TDM) is about changing behaviour. It asks commuters, businesses, freight operators and spectators to travel differently: to retime trips, reroute, switch mode or not travel at all. Behaviour can’t be fully modelled – assurance comes in testing. That makes test events one of the most valuable, and most misused, tools we have ahead of a major event.
Last week’s confirmation that the United States will host the inaugural FIFA Women’s Club World Cup in January 2028 brought that into sharp focus for me. With LA28 now less than two years away, it’s worth asking which opportunities actually count as tests.
What makes a good test opportunity
In our time working on Olympic Games, Commonwealth Games, Football World Cups and Rugby World Cup programmes, the strongest tests I’ve seen share a few traits:
- They collide with normal life. Event-time pressure comes from event demand landing on top of background demand (those going about their everyday business). A weekday event during work hours tells you far more than one on a Sunday afternoon.
- They use the same network. The same corridors, venues, transit lines and freight routes the Games will rely on.
- They create simultaneous demand. Using one venue is a stadium operation. Several venues at once, plus live sites, is a network test.
- They let you deploy the real measures. Not just observing, but running the employer outreach, retiming asks, freight guidance and public messaging, then checking whether anyone responded (spectators AND background demand).
- They’re measured properly. Baselines, counts, surveys and business uptake, with before-and-after comparisons. Without data, you’ve hosted an event, not run a test.
- They leave time to adapt. A lesson learned 18 months out can reshape the plan. A lesson learned six weeks out becomes a risk register entry.
- They exercise the real governance. The same agencies, decision-making and sign-off chains that will operate at event time.
What doesn’t make a good test
The things to avoid if TDM is the primary interest to be tested:
- A single-venue weekend event with a local crowd who already know how to get there
- An audience profile that looks nothing like the event in question
- Measures being showcased when nobody has the appetite for them to fail
- No background travel pressure, so success tells you nothing about event conditions
- Events that are too late for findings to be acted on, or held somewhere else entirely
The question isn’t whether the event went smoothly. It’s whether we learned something we can still use.
Three events, three distances from the Games
The LA28 calendar offers three very different opportunities. Each sits (or sat!) at a different point on the runway.
FIFA World Cup 2026: two years out. This summer’s matches at SoFi Stadium were arguably the closest thing to a Games-scale rehearsal Los Angeles will get. There were summer conditions, international visitors, weekday fixtures and fan festivals running alongside a working city. It was a genuine chance to test business engagement, retiming messages and multi-agency coordination, with time to act on the results. The limitation is that it was essentially one venue cluster, not the simultaneous, region-wide demand of an Olympic and Paralympic Games. The real question is whether it was treated as a TDM test, with baselines and measurement, or as an event to get through.
Super Bowl LXI: 17 months out. Super Bowl LXI comes to SoFi in February 2027. It’s high profile, heavily secured and logistically complex, which makes it useful for perimeters, rideshare management and venue access. But it’s a single Sunday in winter, with a corporate-heavy, car-reliant audience. It tests event operations well. It tests demand management much less, because (as it’s a Sunday) there’s little background demand to manage.
FIFA Women’s Club World Cup: six months out. The inaugural FIFA Women’s Club World Cup runs from 5 to 30 January 2028, with 19 clubs participating and host cities still to be named. If Los Angeles is selected, it will be the last major multi-match tournament on the network before the Games. That’s too late to redesign a TDM programme, but well timed for a final live check of messaging, partner coordination and governance. The caveats are winter conditions, smaller crowds and an audience profile unlike the Games. And until host cities are confirmed, it’s a reminder that you can’t build a test programme around events you don’t control.
The bigger point
Los Angeles doesn’t lack events. What it needs is to decide in advance which ones will be treated as tests, with defined hypotheses, measures actually deployed and data collected. Where an opportunity is too small, too different or too late, we have to be honest that “it went fine” isn’t evidence the Games will. Naturally LA28 organisers have a sharp focus on possible test opportunities, including we understand potentially using next year’s Triathlon World Championships, however the true test of the audiences response to TDM activities will be challenging to pursue not least as the transportation operation planned for the Games will not be in place.
Test events should be designed to find weaknesses, not to reassure us.....
What’s your view? Which events, in LA or elsewhere, have genuinely moved an event TDM plan forward? Please come say hello@intheround.global as we’d love to get into a conversation about it.
