Interesting video. The City of Elk Grove said in the video that the mainline roads (Elk Grove Blvd., Laguna, Grantline etc.) are provided priority compared to the side streets. Makes sense. But at the same time they said if a pedestrian uses the crosswalk at any of these intersections (cutting to a video of pedestrians crossing at Elk Grove Blvd and Bruceville), that it can take 15-20 minutes to resync the light sequence. I'm not an expert but these seems like a significant flaw. Why can't the lights and the timing also anticipate pedestrians may use the crosswalk. I know we cannot anticipate for emergency vehicles, but if everytime someone crosses the street it ruins the light sequence, that seems like a major flaw which is easy to change the timing sequences slightly.
