DID THE APPS SOLVE THIS read it carefully ...Smart roof signs
Goodbody discussed the proposed new vehicle standards, including requirements concerning roof signs and the information that should be displayed on them. The broader objective was to make taxis more readily identifiable and to provide passengers with useful information about the vehicle/driver.
However, I wouldn't attribute a specific “smart roof sign” system to Goodbody without qualification. The detailed electronic/intelligent roof-sign concept appears to have been part of the subsequent regulatory/industry reforms, rather than a central Goodbody recommendation.
The regulations that followed did standardise roof signs, including the licence number, area identification and, where applicable, dispatch/booking contact details and wheelchair-accessible identification.
On-board CCTV
This is different. CCTV was not one of the principal Goodbody recommendations in the 2009 economic review. The report was primarily concerned with the economics and regulation of the SPSV sector—licensing, supply/demand, vehicle standards, dispatching, driver incomes, accessibility and service quality.
So if you're looking at a list of proposals that includes “smart roof signs + CCTV + dispatcher affiliation + wheelchair accessibility”, I suspect you're looking at a broader set of taxi-reform proposals from around 2009–2011, rather than recommendations contained exclusively in the Goodbody report.
