The Relationship between Traffic Signal Phasing-Sequence and Intersection Geometry Design

In traffic signal control, signal phasing and sequence have close relationship with the intersection geometry design. Now, more and more waste of intersection resource and accidents are due to incorrect setting of phase, sequence and intersection geometry design. Furthermore, most traffic signal control systems seldom take account of optimization of signal phase and sequence, especially the relationship between Phasing-Sequence and intersection geometry condition. With the development of intersection design in China, these systems can no longer adapt to this change. So it is useful to do further research on this point. It will make more efficient use of intersection resource and give valuable ideas for upgrading the traffic signal control system.
