At the intersection of Morse Ave and Cottage Way in the Arden-Arcade community of Sacramento county, there is a pedestrian scramble. What this men’s is that the pedestrian signal is on, for walk, in all the directions at once. They are also called Barnes Dance, for Henry Barnes, the traffic engineer who popularized them, and exclusive pedestrian phases.
Sometimes these intersections have marked diagonal crosswalks, as a reminder that diagonal crossings are permitted, and sometimes they do not, but a pedestrian may cross diagonally whether the marked crosswalk is there or not.
I am most familiar with these from Reno (I lived in Carson City for some years), which has several along Virginia Street in downtown. I’ve seen them other places, but don’t recall exactly where right now. At every location where I’ve seen them, right turns are prohibited on red, by signing, so when pedestrians are crossing, no cars are moving at all, and there is no issue with drivers failing to yield to pedestrians using the crosswalk.
I think that every intersection that has heavy pedestrian traffic, particularly where many of the pedestrians are crossing one street and then the other, should have pedestrian scrambles. Yes, they slow traffic a bit, but they increase pedestrian safety and comfort, a great trade-off in my opinion. Many scrambled that existed in the past were removed by traffic engineers who wanted to prioritize vehicle flow over all other considerations, including safety, but it is time to bring them back, at least in select locations. See Governing Magazine, Cities Revive an Old Idea to Become More Pedestrian-Friendly, or search the Internet for pedestrian scramble for both recent and old installations.
The county had this to say about the intersection:
- The all-ways crossing, also known as a pedestrian scramble, at Cottage and Morse was in place/operation prior to the 2016 Cottage Way modification project. After doing some researched, we discovered it has been in place since the signal was installed in 1969.
- The pedestrian scramble operates 24 hours a day.
- The configuration of this intersection is unusual for the County. The scramble works for this location given the layout and right of way constraints that result in some of the corners only having one pedestrian push button to serve two directions.
- We currently do not have any plans to add diagonal crossings at this location.
- This is currently the only location in the County that has a pedestrian scramble.
Questions about using Leading Pedestrian Interval (LPI) signals at the community meeting on crosswalks reminded me that I had information on these in the city for some while, but hadn’t shared it. A LPI signal gives the pedestrian a 3-second (or more, but the Sacramento ones are all 3 seconds) head start, with the walk sign coming on before the light turns green, so that pedestrians will already be in the crosswalk and more visible before vehicles start to move. These address the common issue of both right-turning and left-turning vehicles failing to yield to pedestrians in the crosswalk. They are one of the pedestrian safety countermeasures identified by the
To complete the story about crosswalks, the locations where crossing is prohibited must also largely be removed. These locations are marked with the ‘no crossing’ sign at right (MUTCD R9-3a). Some of these locations probably never had crosswalks, some had them but were removed when the street was ‘upgraded’. A few of these locations cannot be made safe without complete reconstruction of the street. Freeway on-ramps and off-ramps, of which Sacramento has too many because it has too many freeways and too many freeways designed around commuting instead of interstate commerce, are particularly problematic. However, most locations indicate a clear intent by traffic engineers to prioritize the movement and speed of motor vehicles over all other considerations, including safety. This bias must be ended.
As you can see to the right, at the intersection of Freeport and Oregon, there are residences to the west and businesses to the right. There are signalized crosswalks about 700 feet to the north and about 700 feet to the south, but walking to either of these adds a one-quarter mile walk. Is this reasonable or not? It could be argued either way, but to discount it as Mr. Moore did demonstrates bias against pedestrians. The Google Map photo is from before the removal of the crosswalk.
Curb extensions, also called bulb-outs, have been installed on all four corners at the intersection of 16th Street and N Street in midtown Sacramento. The extensions are the width of the parking lanes along both these streets. N Street has bikes lanes, which are not restricted by the extensions, while 16th Street does not have bike lanes, and won’t until the street is reconstructed into a more complete street at some unknown point in the future.
