UNIFORM AND VARIABLE BANDWIDTH ARTERIAL PROGRESSION SCHEMES

Compared with conventional uniform bandwidth progressions, variable bandwidth progression schemes offer considerable advantages for arterial traffic signal control. The variable schemes have a traffic-dependent capability that the conventional schemes lack, providing additional design flexibility and superior traffic performance. A simplified and efficient method for calculating variable-bandwidth progressions given optimized uniform bandwidth progressions is presented. Little's half-integer optimization algorithm is used first for uniform bandwidth maximization, coupled with a combinatorial phase-sequence optimization procedure. The method is then extended to calculate variable-bandwidth progressions using the multiband optimization criterion. A principal feature of this method is that it can be applied to any arterial synchronization scheme after the uniform bandwidth has been maximized.
