Are signal re-timings worth it?

If signal retiming makes travel faster, won’t that just induce more demand and erode any gains made? According to Miovision’s Senior Traffic Engineer Sajad Shiravi, even with some increased demand, signal retiming still makes a measurable improvement in traffic. 

In his recent LinkedIn post, Sajad shows that even as the cost of travel (measured by time) decreases and demand increases, the retimed signals still improve the flow of traffic compared to the status quo option. Traffic may continue to increase, but travel times would be significantly worse without signal timing, even with the growth.
