G.M.'s decision to move its H.C.C.I. program out of the laboratory and into what Mr. Najt calls the advanced engineering phase, as well as beginning road tests, signals the automaker's steady progress in critical technology areas, said Matthias Alt, manager of the company's global H.C.C.I. program.
The evidence gathered in the current study could be of particular interest in some applied research areas, such as the assessment of road traffic signalling strategies or the ergonomic design of GPS navigation systems.
