Hey people, there's an easy answer here. It's called a speed bump. Get on it.

Why are there no pedestrian sidewalks on the Stevens Creek Trail Commuter Motorway?
It has become very dangerous walking with all the fast moving commuter bicycles and high powered heavy E-Bikes.
Ask any walker about safety on what used to be Stevens Creek Trail and Wildlife Corridor and you will hear the same concerns.
Pedestrians do not walk in city streets with vehicles. Pedestrians walk on sidewalks that afford some level of protection.
Why are walkers forced to mix with the vehicles along Stevens Creek?

I personally worry more about the violent drug dealers with loaded AR-15s living in the RV's in my neighborhood.

Public records fully indicate the lack of incidents happening on the trail. Safety is a big concern everywhere. The headline is overly sensation if you look at the actual numbers of incidents. I guess the paper ignored that or didn't think about it before the headline was written, but in reality, Nothing to see here.

To get bicyclists to obey the speed limits and other safety practices on the trail, all you need to do is: Go to Google and warn them they had better train their people to abide by these laws. Also tell them that they will have to pay for the speed bumpbs (another commenter suggested these, a good idea).

But over the last several years, I have actually noticed a decrease in flagrant, dangerous behavior on the trails by rabid Googlers...

What happened to the guy who hit him? Did he/she get a ticket and a fine and pay for the hospital fees?

@Scott: The article says the bicyclist did not stop, so he/she evaded responsibility. Hit and run.

The woman I know who got a broken shoulder when hit by a bike on SCR some years ago had to pay for everything. She made a u-turn into the rider and while she did get blown up, she was on the hook for the medical bills because it was determined to be her own fault, or more precisely, no fault of the cyclist. The witnesses played a part in coming to this determination.
This is why I like the cameras on bikes they have, and why I fully encourage other trail users to wear them. That way everyone can see what really happened. That said, not much actually does happen on the trail. We're all relatively safe there if you look at the stats. Anecdotal incidents get press though.

Time for Caltrans and the City of Mountain View to step up and address this location. Stating the increased usage from 2012 to 2015 as 96% cloaks that rise - say it as 25 times increase in users and it better reflects that magnitude of increase. As another commenter mentioned, this is the narrowest and darkest place on the Stevens Creek Trail and it also has a blind corner. Many of the accidents here go unreported, so the statistics don't tell the whole story.

Bottom line, time to improve this. As a commute route, this is the nexus where nearly ALL commuters come together and has the highest traffic. This section of trail was opened in 1996, over 20 years ago. It opportunistically used the existing underpass to squeeze in a narrow trail. The time has come to rebuild this to the current Caltrans level for a freeway crossing, which I believe to be 15 feet wide.

Creek improvements to support fish passage are also needed in this area, so perhaps the two can be addressed together for some economy?

Speed Humps are te only solution to slowing traffic, and nobody ever wants them, until they become a victim.

And why don't they ticket reckless cyclists? They want equal rights on the road, give them equal rights, why should they get a pass?

Re: "Speed Humps are te only solution to slowing traffic"

Actually, on a multi-use trail like SCT, I would expect speed humps to merely direct speeding cyclists to the unpaved area just to the right of the hump. What slows down cyclists are the mazes that they cannot go around.
