I took a couple of photos while we were traveling along Espana Boulevard. I wanted new photos of the traffic signals along Espana to use as visuals for my examples whenever I discuss traffic signals and their coordination or synchronization in my lectures.
Green signal for traffic. If the traveler is able to travel at the optimum speed, one will be able to catch the green light at so many intersections along Espana. The road is the major thoroughfare in the area and traffic along it is prioritized over those from the side roads to maximize the throughput along Espana.
If one catches a red light at one intersection, it is possible that the traveler will catch a red light in the next intersection(s).
