"The police presence will increase significantly, particularly in the entrance area," said Kunibert Schmidt, chief organizer of the IAA and managing director of the auto industry association VDA.
For the first time, visitors' baggage will be searched at the entrances.
At the beginning of the last IAA two years ago, terrorists attacked the World Trade Center in New York and the Pentagon in Washington. Schmidt said that the show organizers have learned from the 2001 crisis and that communication among police, exhibitors and the show organizers VDA will be improved.
This year's auto show will include 125 world premieres.
Schmidt said that to increase show attendance, the VDA will run a large-scale TV campaign for the first time. The association will show 20-second spots during prime time on ARD and ZDF (public German TV stations) and RTL (a private German station).
The TV campaign will run from August 30 until September 8.
