What’s the best way to advocate for crosswalks/pedestrian signal heads on busy roads?

Before y’all say it- I know Houston isn’t walking friendly. Still would like to do something though.

I live near Washington (closer to downtown not the bars) and I walk to Sawyer Yards & the bayou pretty often with my dog. The intersection of Washington Ave & Sawyer St is getting busier with all the new developments, but crossing the street is a mess. I’ve almost been hit 4 or 5 times in the last 2 months. Since there are no crosswalks or pedestrian signals cars are always turning without paying attention.

Who is the best point of contact? TxDot? Congressman? The City?
