The music is so nice to listen to and the loading screen was cool and smooth, only it was confusing to know if I clicked the arrow.  A hover over an arrow would be helpful to add in the future! Good job though!

This is a kind of game that I would play. I love minimetro/minimotorways and my submission also shares some inspiration with your idea. I think the idea of having a miniature view of the intersection could had been given some more interesting gameplay. My main issue is that it was not obvious what intersection you are controlling and why cycle only affects a single arrow. I’d expect cycle to cycle all 4 lights in an intersection. Either way, an interesting start.

It was hard to play. I get that I voted 1* on graphics since they were all imported. Polish 2* - There the control was inobvious at first, and hard to use once I understood it. Theme was good. "Flow of Traffic" though the flow of UX was poor, so I put it a 4*. I put innovation at 5*, I haven't played a game quite like this. I'm not sure how well this concept can be made, but it feels like there is more opportunity. for 1, I would start zoomed in with 1 intersection, then as enough traffic changes, zoom out to cover more. 
The traffic signals feel tedious instead of fun. Swipe operations on a phone might work better. I.e. swipe through an intersection to change the flow to what you did. Auto turn red the others. That might work better, at least in UX.
