I too pass that Safra junction quite often. I find that the
lights favour traffic on Ave 5 than those on Ave 1. As almost
everytime I approach that junction from Ave 1, the light will be
red. Only on my lucky day, very rare, do I breeze through that
junction on a green.
It is true that the junction is well regulated, with ample green
arrow time, but if drivers want to beat the lignts or on
coming vehicles then what more can be done. I
think there are cameras there already.
