The Influence of Geometry on Operational Performance of Signal-Controlled Junctions
This study investigates the influence of geometry on the performance of signal-controlled road junctions under fixed-time and system D traffic responsive signal control. The study uses 16 experimental scenarios with several different traffic and geometric characteristics. Results showed that the principal effects of lane width and turning radii were as expected in the estimated log-linear models for delay per unit of time. Findings also showed that the effect on delay of the interaction between lane width and turning radii was significant at light traffic flow, while the interaction between turning radii and signal control played a significant role at medium traffic flow. These results can be used in the design of a junction in relation to its geometry and in the choice of the best signal control strategy.
