We have been following the trials and tribulations of the Poplar-101 ramp for some time including here. If you read through the comments to that post you will see Jennifer noting
"Interestingly, that intersection/on-off ramp was studied by Hexagon Traffic engineers a couple of years back, and determined to have a lower than average accident rate, whereas the intersection immediately westward by that field was determined to have a higher than average collision rate, though cars are going much slower (crawling) at that point. I think the lower than average rate is because of the heightened awareness at the intersection-proper."
B'gamers have more than a passing interest since the next intersection to the north is Peninsula Ave. where threats of a mondo-expansion and emminent domain proceedings continue. The Daily Journal is updating the construction plan and states, perhaps incorrectly since it provides no statistics
The busy four-way intersection is known for having a high rate of accidents. It mixes three stop-sign-controlled directions of traffic competing to enter the freeway or cross Poplar Avenue, with drivers coming off the highway who aren’t required to stop.
and describes the work
The project involves creating a center divide along Poplar Avenue from Amphlett Boulevard near the highway to about a block west to Idaho Street. The median would prevent any left turns at Idaho Street and prohibit most (ed: most what? is this a typo?) at the Amphlett Boulevard intersection, except for drivers coming off the highway.
The center divide would eliminate southbound drivers on Amphlett Boulevard from entering the highway or crossing toward the Department of Motor Vehicles office, instead they would be forced to turn right heading west on Poplar Avenue. Drivers heading north on Amphlett Boulevard would be forced onto the freeway and those heading east on Poplar Avenue would be prohibited from turning left to head north on Amphlett Boulevard.
All in all this seems to make sense to me. Of course the Law of Unintended Consequences will cause more people to skirt around the DMV and make the easty right onto 101. The real bad idea is noted in the piece as well
A much larger initiative to consider closing the Poplar Avenue highway ramps, and relocate them further north toward Burlingame is also underway.
The city and San Mateo County Transportation Authority are conducting an environmental review of the Peninsula Avenue interchange project that would involve closing the Poplar Avenue ramps. Currently, there are only northbound on- and off-ramps at Peninsula Avenue, requiring drivers to travel down Amphlett Boulevard to enter at Poplar Avenue.
It's just plain dumb to reduce ramp locations.
Peninsula has been improved enough. Why can't these drones leave well enough alone?
