Preliminary assessment of two multi link road experiments comparing the use of in- car dynamic advisory speeds with normal driving.

A single small car was computer equipped to display speeds to the driver, thus simulating dynamic advisory roadside signs. The car was driven along a 3.5 km arterial road in peak and off- peak periods under vehicle actuated signals, controlled by flexible fixed time or adaptive traffic responsive modes. The main experiment was carried out over eight fixed time and four adaptive days. The conclusions and findings of the experiment are presented here.
