Hello Mateo how you doing I'm sorry on my delay to respond ,I was traveling for work My idea is to do a color signals combine with same color line on the lane floor between withe dotted lines corresponding to your destination or exit , same concept using GPS blue line. This will help to the drivers be on the correct lane with out changing lane or reducing speed to lactate witch way to go, it's a visual easy way as every body is familiar this days with navigation using color line. I will add to my project and sketch how it will look. Let me know if this help to understand my idea. I hope the other two ideas I have I have time to post it as combine with this I know it can make traffic better in all cities. It's like make our commute vehicles system when is moving as a mechanical watch.
