Introduction
Incontrol continues its journey in analyzing the pedestrian activities at special infrastructures. A project is done at the soccer stadium of PSV Eindhoven. Since PSV became champion of the Dutch league for 7 times in the last 10 years one could say that PSV Eindhoven is one of the most successful soccer teams in the Netherlands. The stadium has a capacity of 35.000 seats located in an upper and a lower ring in the stadium. Every soccer game PSV is seeking to optimize the pedestrian flows by managing the different activities that people undergo during their stay. These activities include for example, ticket sale, security check-in and the sale of food and beverages. Next to this, PSV want to create insight in evacuation scenarios. Since doing an evacuation drill with 35.000 people is quite a complex matter, PSV is still searching for other methods that can help in analyzing different evacuation solutions. The last years the stadium, next to soccer games, has been used for other purposes like concerts. Since the infrastructure was not initially created for these other commercial purposes, PSV also seeks for optimization of the pedestrian flows during these events. In the following paragraphs there is described how INCONTROL helped PSV in dealing with these issues.

Goal
By mutual agreement there was decided to develop a customized simulation tool. With this tool PSV itself is able to create and analyze different scenarios. The tool is developed in two phases. In the first phase the soccer game scenario is developed and in the second phase the event scenario will be developed. With the use of graphical user interfaces (GUI) INCONTROL made the tool a user-friendly device. The user can apply and save his/her own settings, and hereby create different models for different situations. The user can do his/her own experiments after which the output is then visualized using excel. So next to the overall view of the pedestrian flow through the different layers and activities of the stadium also quantitative output is created in order to do a proper analysis of the designed situation.

The tool
The tool is developed using the pedestrian flow simulator PLATO. In addition to the default PLATO library, customized atoms where made that represented the different activities which a person could endure in the stadium. For example:

• Tourniquettes (high and low)
• Toilets
• Bars
• Coin sale machines
• Emergency exits

Each of these atoms (activities) has their own parameters which can be set by the user to create a realistic situation. Next to this they also have a 2d and 3d visualization to create a realistic representation.
The tool’s infrastructure is built in different layers which each can be turned off individually so the different layers and sections of the stadium can be analyzed on a detailed level. With the use of entrances, exits and passages the different sections and areas in the stadium are connected or not. In this way a pedestrian will create its own route through the possible connections to reach his destination. The eventual destination will be the tribune area that is assigned to the pedestrian (based on ticket sale). Based on the settings concerning toilet usage, coin sale and food and beverage, the pedestrian will adapt its route to use any assigned activity.
In order to analyze the effect of different arrival intensities of the visitors, the amount, tribune destination and arrival time of the visitors can also be set in the GUI.

Evacuation
The user can create a total evacuation on a pre-defined moment during the simulation run. Visitors will adapt their behavior, for example increase their walking speed. Also the visitors will individually choose an evacuation route based on the available emergency exits and passages. By closing or opening passages and exits during an evacuation the user is able to create its own “What if” situation. By analyzing the model visualization and quantitative output, the user can define and resolve bottlenecks. In this way current and proposed evacuation plans can be validated.

Events
Since the stadium was not initially designed for other commercial events, temporary infrastructure is used to optimize the pedestrian flows during these events, for example female toilets, bars and ticket checkpoints. In this event scenario also the field is used to accommodate the visitors (about 14.000 extra) during the event. Due to these aspects of the event scenarios there was decided to build a second scenario. The scenario will be created based on the design of a major event in 2010. The entire temporary infrastructure will be developed in such a way so that the capacity of these facilities can be adapted in the simulation tool. In this way, well-founded decisions concerning the temporary infrastructure can be made during the design-phase.


Finally
As the partnership with PSV continues, the soccer game scenario is now being tested and validated. The event scenario is now in developed phase but will be finished on time so that next event configuration will be based on decisions made with the help of INCONTROL’s simulation tool.
