Its probably best to perform a study to assess the effects of retiming signals on congestion, queuing, impacts to side streets, etc., before arriving at some feasible and viable options to solve the issue and best optimize signal timing for existing and future demands. My question is the price tag. Perhaps the cost is legit, considering the labor it takes to perform a timing analysis at one intersection, multiplied by hundreds, as well as all of the other data collection and analysis that's probably needed. I wish we could see the scope of the study that justifies the cost.
