Abstract

Traffic and corridor studies from Perth are analysed together with an international comparison of 32 cities to seek an answer to this question. The data suggest that free-flowing traffic does not save energy or lower emissions overall in a city contrary to previous assertions. This is despite the apparently clear advantages in efficiency for individual vehicles. The reasons for this are examined in terms of travel distances, alternative modes and suboptimal vehicle usage due primarily to the land use structure of the city. The effect of congestion on time savings is also assessed.
