Bandwidth Optimization of Coordinated Arterials Based on Group Partition Method

An approach to the application of bandwidth-oriented signal timing has been proposed based on a group partition method for coordinated arterials. Firstly, the approach is an improved and detailed bandwidth optimization method, including detailed steps to calculate upper/lower influences and relative offset for intersections, with different conditions. A window program BOTSD (Bandwidth Optimization and Time-Space Diagram) was developed to obtain optimal progression bandwidth and draw a time-space diagram for an arterial. Secondly, a group partition method of coordinated arterials to get optimal bandwidth was developed. In the case study, after calculating valid and optimal bandwidth for every possible subgroup, arterial progression bandwidth for every combination of possible subgroups can be obtained using the improved bandwidth optimization and group partition method. The results of intersection control delay and progression bandwidth for every combination of possible subgroups show that bandwidth-based solutions generally outperform delay-based solutions. Meanwhile, the signal timing plan from improved bandwidth optimization and group partition method is much better than the result from Synchro 6.0 optimization function and Messer's method.
