While we're hashing out the best way to (re)configure the roads, priorities for paving, and other ways of expediting traffic, let us not forget the factors that we have the least amount of control over, but contribute the most to road safety:
The following pic was captured while stopped at the N. Peachtree stoplight. (I threw the Mom-mobile in park while I got this - no balancing a gear shift and electronics at the same time for me.) What is wrong in the scene below?
Look closely and you will notice dude in the public safety vest perusing the AJC behind the wheel. While this image was taken while traffic was stopped, the aforementioned dude was reading his paper at the same time he was driving down Tilly Mill.
Paving, road configurations, synchronizing traffic lights are all necessary to get traffic through and out to where it's going expediently. But the roads are not going to be any safer until the idea of personal responsibility and good driving habits gets pounded into a few more skulls.
So if you know, or are the supervisor of dude driving a brown Chevy El Camino Conquista (!!) with the license tag below, you might want to pull him aside and explain the benefits of driving safely. Because clearly, he doesn't currently get it.
