THE EFFECTS OF TRAFFIC SIGNAL COORDINATION ALONG AN ARTERIAL IN ADELAIDE

Travel time and delay surveys were undertaken "before" and "after" the introduction of computerised signal coordination along Belair Road/Unley Road in Adelaide. This report shows the main results obtained from these surveys in terms of run overall travel time, stopped time, number of stops and the delay at a major intersection. It was found that, whilst traffic volumes have increased by between 7 and 15 per cent relative to the "before" situation, overall travel times have remained virtually constant. Overall delay and number of stops showed a marked improvement after implementation. The extent of those improvements vary with time of day. For morning peak inbound and evening peak outbound traffic, mean overall delay has been reduced by 24 per cent and 37 per cent respectively. (Author/TRRL)
