Samenvatting
Results of a test with feed- back to car drivers are described. The feed- back is produced by a flashing road sign activated by motorists whose vehicle speed is too high for safe driving through a sharp bend.In the test, fast drivers are defined as drivers with vehicle speeds of 80 km /h approx. 120 meter before the bend. Results show that installation of the new road sign in itself (without flashing) influences the drivers.
