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 is a problematic intersection. Cars stopped for the light rail gates between R Street and Q Street often stop throughout the intersection, blocking both the north and south crosswalks over 16th Street, as well as the intersection itself, preventing vehicles along R Street from proceeding while the traffic is stopped. As with all multilane streets, but particularly high speed, one-way arterials, drivers in one lane may stop for a walker while the others will not. I see this every day, and this intersection is worse than most. For reasons I don’t understand, traffic speeds on 16th Street northbound are noticeably higher than 15th Street southbound, even though the design of both streets in the same.
So, how’s it working. Well, I’ve so far only had the chance to observe it for 15 minutes. I’m not sure it is making much difference. About 10% of drivers stopped at or close to the advance yield lines. About 70% of drivers stopped at the forward edge of the flex posts, about 10% stopped over the crosswalk, and about 10% did not stop for people using the crosswalk. I saw three people nearly hit by drivers. This is not unusual, and it not worse than before, but it is not good.
Below is an example. The driver to the left stopped over the top of the crosswalk, even though it was clear that traffic ahead was stopped for the light rail gate, and there was no space to proceed into. The driver to the right stopped before the crosswalk, but not at the advance yield line. Not visible it the driver in the closest lane who did not stop at all because there was a space in that lane across the intersection.
While I appreciate the effort, I’m not sure if the results will be what is desired, which is the ability of walkers to safely cross the street.
In the long run, the reallocation of roadway on 16th Street to reduce the general purpose lanes from three to two will help this location a great deal, but I don’t know when that will happen. It could be years away.
With the new businesses on R Street to the east, and the street dining area on R Street to the west of 15th Street, this intersection has become quite busy with walkers, bicyclists, scooters, and motor vehicles. It does deserve attention.

Time to tunnel under the light rail tracks?
There are now two additional installations, that I know of, 16th St at O St, and 15th St at R St. I’ve spent more time watching. The channelizations does seem to slow drivers a bit, the same kind of friction that parked cars provide if the lanes are not too wide, and this is backup up by the right hand lane on 16th St at R St, which does not have a curb extension (bulb-out) to narrow the lane sufficiently, does not slow as much.
I’m not seeing any better yielding to walkers at these locations, though. I guess this is progress, when people are hit by drivers, the drivers will be going slower and therefore less likely to kill the people, but that is faint improvement. What we go through in often vain attempts to slow down drivers and cause them to consider other people!
