COP Outcome development and evaluation
Community and social considerations formed a major part of the project investigation, design, commissioning and operation phases. The following initiatives were undertaken to address community and social needs:
- Consultation with user groups during the design phase to assist in the identification of appropriate messages and select the location of cameras and signs.
- An extensive public information programme prior to commissioning explained the NATMS via media releases and brochures.
The Ngauranga Gorge ATMS User Group was formed as a forum to provide feedback on the effectiveness of the system and identify options for improvement.
During the installation of the cameras it became apparent that some residents and businesses were seriously concerned about their rights to privacy, and saw the cameras as a major invasion. Some form of video image blanking had to be provided. Initially they investigated mechanical blanking, by preventing the camera from rotating beyond a certain point. However, this seriously affected the functionality of the camera. The next option was erecting shields around the cameras to restrict viewing of certain areas. This caused problems with vibrations during high winds. Finally, it was deceided to install a different camera with the ability to blank the image electronically. This has proven to be a very effective solution to a sensitive social issue.
A development that is being investigated is the linking of key video cameras to a website, allowing the public to check on driving conditions along the route at any time. It's anticipated that this will be used by people especially around holiday weekends and major events.
Environmental issues
There was a relatively minor level of construction involved and environmental considerations were not a major issue. Potential adverse effects were identified and the following actions taken:
- The overall number of new structures (including gantries and poles) was reduced by strengthening existing structures and placing others at strategic locations. This reduced the quantity of raw materials used, and also adverse visual affects for drivers.
- The new structures were designed to be in keeping with the existing structures and sign posts in the Ngauranga Gorge. This provides an aesthetically pleasing and consistent environment for drivers.
- The fibre optic cable connecting the system components was installed in compliance with Transit New Zealand's Environmental Code of Practice. This ensured that trenches were dug during dry weather to minimise the risk of run-off.
- All cabling was laid underground to reduce the overall visual impact.
