re: EBR Parish has spent over $700 million on traffic projects since 2006.

I don't live in Baton Rouge anymore, but almost all of the GLP projects I remember were widening projects on the south and west sides of the city. If traffic is still getting congested after the roads were widened and new signals were built, that's a YOU (citizens) problem and not a THEM (parish government) problem.

There are two ways for the citizens to reduce congestion: live closer to downtown or commute outside the rush hour. If you look at EBR on Google Maps, you can turn on the traffic view and then select "typical traffic" to see what it's like on an average day. It looks terrible at 5:30 PM on most weekdays and then mostly clear at 6:30 PM. That means you should vary the times when you commute if you hate sitting in traffic. It's something everyone in Houston or Atlanta already knows.

Baton Rouge's other problem is that too much of the commuting traffic flows through the I-10 corridor between I-12 and I-110. It's probably 40-50% of the weekday commuters, which is a massive number. They've already put a lot of effort into making Florida and Airline viable alternatives, but they still aren't freeways.
