Currently, all CNS components are imported except digital maps that been produce by local map provider referring to document ISO 14825:2011 — Intelligent transport systems — Geographic Data Files (GDF) — GDF 5.0. Even though the document has an intensive guideline but most of it does not suit Malaysia road network. This paper discussing about the type of access restriction and prohibited manoeuvre classification that exists in the Klang Valley road network. Data collection and investigation were done using Sanyo CNS preloaded with 2007 digital maps. A result from the investigation shows that there are six (6) type of prohibited manoeuvre exists in Klang Valley. The intention of this investigation is to incorporate the Malaysia road models with the GDF document so GDF conversion and quality checking tools can be developed according to Malaysia road model. This can avoid an error in CNS maps due to the human operator interfere.
