In the year 2010 the World Expo will be held in Shanghai, China. The Dutch design studio Kossmann.dejong was awarded one of the five theme pavilions called the "Urbanian Pavilion". In total, the World Expo has 200 participants, for a duration of six months. About 70 million visitors are expected. On average 40.000 people will visit the "Urbanian Pavilion" daily. As Kossmann.dejong still is in the design phase of the pavilion, the deadline of the final design is in sight. Important decisions concerning the infrastructure and visitors flow therefore have to be made soon. With the use of simulation, Incontrol Enterprise Dynamics will help Kossmann.dejong in creating a clear view on the effect of different scenarios on the visitors flow. In total, the visitors will walk 800 meters through the pavilion. During this trip they will enter six theme areas. In each of these areas a different show is presented.

Objective

The goal of the project was to measure the "performance" of the pavilion under different scenarios. Important issues were:

• average stay time inside the pavilion
• average waiting time in the queue before entering the pavilion
• quality of experience
• an emergency situation

The quality of experience was defined as the key performance indicator of the project. This quality is measured with the value of the density (m²/person). As this quality of experience is stated an important issue, the minimum desired value of the density is 2 m²/person. With this minimum desired value Kossmann.dejong believes that every visitor will have enough space to enjoy the pavilion in a comfortable way.

Parameters

There are several parameters that influence the quality of experience:

• The size of the theme area's (m²)
• The duration of the shows in the theme area's (minutes)
• Entry rate of the visitors (persons/hour)

With the use of simulation Incontrol Enterprise Dynamics will help the exhibition architects in making the right decisions concerning the design of the pavilion.

The model

Based on the knowledge and atoms about the pedestrian flows used in the airport and railing industry, Incontrol Enterprise Dynamics constructed a simulation model of "The Urbanian Pavilion". New shapes of walking area's where constructed to build a realistic representation of the true pavilion infrastructure. With the model the staytime inside, the waiting time and the density of the theme area's can be monitored. Also an emergency event can be created. In an emergency situation visitors increase their walking speed and will move to the closest (emergency) exit. With this event the total evacuation time can be analyzed.

First Results.

When the initial design was simulated the first conclusions were drawn. In two of the six theme areas the average density was to low (<2 m²/person). Either the surface of the theme area was to small or the shows where too long. Also in the initial design two escalators where planned to be built, however one escalator was enough. This meant a significant difference in the investment of the construction.

As the project is still running Kossmann.dejong is making changes to the initial design. These changes will also be evaluated with the help of the simulation model. In this way Kossmann.dejong is able to create a comfortable and pleasant watching experience for the visitor of "The Urbanian Pavilion".
