    Since the 2nd Workshop of the Lower Cretaceous Cephalopod Team in Mula, Spain (Hoedemaeker et al., 1993), several ammonite zones and ammonite horizons have been introduced that still have not be inserted in the standard zonation of the Mediterranean area. In the present survey (1) the different results of various independent specialists are compared, (2) an attempt is made to correlate their resulting zonation schemes, and (3) recommendations are given for the use of the newly introduced zones and horizons in the Mediterranean region

    This paper describes the set-up of a AVG knowledge database from the AVV Transport Research Centre from the Dutch Ministry of Transport, Public Works and Water Management. The database provides a categorised overview of all research performed in The Netherlands in the area of Automatic Vehicle Guidance (AVG). Two analyses are performed on the documents in the database: on traffic flow effects and on individual driving behaviour and acceptance of ACC
