KDC

On November 3rd KLM and LVNL organised in co-operation with CROS a residents meeting on the subject of CROS Pilot 3b'+ (accent-plus). The objective of this pilot project is to investigate the possibilities for further reducing noise annoyance through concentrating traffic better in between the communities of Hoofddorp and Nieuw-Vennep.The meeting provided an opportunity for the attendees to get informed on the expected changes in annoyance resulting from increasing the turn radius of CROS pilot 3b’+ route. In support of the communication, the KDC showed computer animations of the changes.

During the residents meeting KDC presented the results of noise calculations and they were discussed with resident representatives of the communities of Hoofddorp, Nieuw Vennep, Zwaanshoek and Cruquius. In addition to the aforementioned, the municipality of Haarlemmermeer and the Ministry of Transport, Public Works and Water Management were also represented.

A range of scenarios were investigated with noise calculations. The most important aspects of the scenarios were:

1. The differences in two route variants of the fixed radius turn (1 and 2).
2. The differences in the participation on the new route; either only KLM traffic, or all the traffic on the route.

Computer animations depicting the instantaneous noise level in dB(A) in the communities of an average departing flight on the route design were presented. Additionally the results of the calculations of (changes in) forecasted annual noise exposure (dB(A) L_DEN and L_night) were presented.
