USDOT fatality data for Sacramento
The US Department of Transportation (USDOT) has released data on fatalities throughout the US, allowing communities to drill down to the issue in their location. Streetsblog has a great introductory post at How Deadly is Your Community’s Streets? New Data Tool from USDOT Shows the Hard Truth (2023-01-08), and USDOT’s story map is Our Nation’s…

Sac Vision Zero intersections & red light cameras
I’ve written previously about Vision Zero high injury intersections in the City of Sacramento: Sac Vision Zero new intersections map, Sac Vision Zero top intersections all modes, Sac Vision Zero top ped intersections, Sac Vision Zero Top 5 Corridors and top intersections, and Sac Vision Zero flaws. The City of Sacramento has red light cameras at the following locations: Mack…

lower speed limits?
Assembly Bill 43 (Friedman), passed in 2021, allows cities to set lower speed limits in specific situations. The 85% percentile rule says that speed limits should be set at the speed 85% of drivers are going, the prevailing speed, causes speed limits to increase, as drivers reset their normal speed to be somewhat over the…

red light cameras
The City of Sacramento has 11 red light camera locations: Red Light Running Program. Of these, some are at high-injury intersections, but most are not. These locations are cross-referenced with high injury intersections shown in the post Sac Vision Zero new intersections map. Location Top all Top ped Top bike Mack Rd & La Mancha Way/Valley…

Hmm. 16th St traffic calming
A new traffic calming feature has showed up on 16th Street approaching R Street in midtown Sacramento. Paint and flex posts have been placed between the travel lanes. Advance yield lines (‘sharks teeth’) were also painted, showing where drivers should stop when yielding to pedestrians. I’m not sure what to think of this. Certainly this…

I can’t point you to the language for specifics, since the legislative website has not been updated yet. You might call this a gut and amend bill, but since the original subject was ‘pedestrian…

the VZ solution we won’t talk about
The one thing that no one in the transportation advocacy community wants to talk about is speed-limiting vehicles. Speed-limiting means that vehicles cannot operate over the speed limit selected for a section of roadway. The technology for doing this is largely already in place on modern motor vehicles, as they already monitor their speed and…

Sac Vision Zero new intersections map
Thinking about the intersections maps and what they show (Sac Vision Zero top intersections all modes, Sac Vision Zero top ped intersections, Sac Vision Zero Top 5 Corridors and top intersections), I thought it might be interesting to present the data in a different way. The two maps below show all of the top intersections identified in the…

Sac Vision Zero top intersections all modes
And now for the third analysis of high injury network intersections and the relationship to the Sacramento Vision Zero Top 5 Corridors. The dataset this time is all killed or severe injury collisions in Sacramento, for all modes of travel, for the period 2009-2017. Of the 1641 collisions in the city, 322 (20%) were at…
