Abstract: The aim of this study is to investigate the influence of geometry on the performance of signalcontrolled road junctions under fixed-time and system D traffic responsive signal control by using 16 experimental scenarios with several different traffic and geometric characteristics. In the estimated log-linear models for delay per unit of time, the principal effects of lane width and turning radii were as expected. The effect on delay of the interaction between lane width and turning radii was found to be of substantial importance at light traffic flow, while the interaction between turning radii and signal control was found to play a significant role at medium traffic flow.
