Slippery paint lines can cause a fall

December 21, 2015

Time for a new helmet after this one served its purpose.

Time for a new helmet after this one served its purpose.

While we all know rain, painted lines and bicycles don’t mix, I found out the hard way on Sunday during a ride.

I’m not the most aware person, as Jobst Brandt once showed me on a ride up Page Mill Road. He said, “Watch out for the black ice.” Two seconds later I was down.

Jobst never let me forget that. So I probably had it coming when I fell on the paint lines on Tantau Avenue in Cupertino next to the fabulous new Apple headquarters under construction.

It was the perfect mix of wetness and bad luck as I moved left to enter a left turn lane at Pruneridge. Both wheels must have been on the bike lane as I looked back.

The bike went out from under me in an instant. Then I got a ride to the same hospital where Jobst once stayed after his fateful accident in 2011.

I won’t say the helmet saved my life, but you won’t see me riding without one. I’ve had too many incidents — broken cranks, slippery roads.

After checking the paint lines, I think they’re old enough to have been put down before better paint-grit combinations came along.

As for the green paint swathes, I think they’re safer when wet because they have grit in them, or they conform better to the pavement. They’re an issue in Australia though.

The slippery white lines were a problem in Portland, Oregon, and had to be re-striped.

Finally, if you’re seriously hurt by a white paint line, there’s always someone willing to represent you in court.

Follow-up: After talking with the eyewitness and carefully reviewing the scene of the accident, here’s what happened. I was riding southbound on Tantau in the bike lane prior to moving left to turn onto Pruneridge. At the location I was observed falling there are patches of green paint designating a bike lane. These have become worn from constant sweeping by a street sweeper assigned to keep dust down where the Apple campus is being built. The combination of light rain, dust and finely polished green paint made this surface an extreme hazard.

I reported the accident to the city of Cupertino via email and letter.

After this incident, I believe the green paint swathes constitute a hazard once they become worn. Not good.

Follow-up 2: I took my wheel and some water to test my theory about the slippery green paint. After testing, I found the issue to most likely be one of a slurry of mud accumulating on a white paint line, not green.

The green paint is a lot like sandpaper in consistency. Although it loses some traction when worn, it didn’t seem any worse than regular pavement.

However, the white lines definitely had less traction when wet, especially with a slurry of mud, which you can see below. A thin layer of mud is deadly for bike wheels. Because this street is in a construction area, there’s a lot of dust being generated. Sweeping helps, but there’s still a layer of fine dust.

I also tested some concrete next to the curb. Surprisingly, even when wet it seemed to have better traction compared to the white paint line. It may be that sweeper does a better job of removing dust from concrete compared to the white paint.

My front wheel went out from under me on a white “paint” section, not green, although I can’t say for sure since I don’t know the precise location.

Silicon Valley needs a transportation system like Zurich’s

Today’s San Jose Mercury News ran an editorial by architect Thang Do that outlined what we need to do to make Silicon Valley a better place to live.

He warns that with all the construction underway, we better do something about our transportation system or we’re headed for permanent gridlock.

He mentions Zurich as a shining example of a city that understands public transportation. Here’s why:

The city has an integrated and comprehensive network of tram, rail, bus, and even riverboats to take you where you want to go in the city, throughout the country for that matter. One ticket gives access to all public transportation, with the exception of intra-city rail.

Imagine stepping out of the Zurich airport with all your luggage and walking fewer than 50 yards to a waiting tram whose platform is flush to the pavement. Just roll your baggage on.

Every tram has an LED screen that shows your location and the stops ahead, including connecting trams. Every stop has a shelter with an LED sign indicating the time of arrival for trams, along with machines for purchasing tickets.

Local trains accommodate bicycles and stations have large areas dedicated to bicycle parking. Many streets have bicycle lanes and because there are relatively few cars on the streets, traffic is not an issue.

VTA light rail does have one up on the Swiss trams: VTA provides racks for bikes.

Zurich and Switzerland have thought of everything when it comes to getting around on public transportation. There’s no need to own a car, which is a reality for most people living in the landlocked country. That’s a good thing because living in Zurich is as expensive, if not more so, than living in Silicon Valley.

We can learn from Zurich. The sad truth about Silicon Valley is that the Valley of the Heart’s Delight once had a wonderful light-rail network, which was dismantled piece by piece with the arrival of the automobile.

In hindsight, we blew it, but we mustn’t give up hope. We can build a transportation system equal to that of Zurich. All we have to do is, in the words of Patrick Stewart: “Make it so.”

Even the fanciest shopping area, Bahnhofstrasse, has light rail.

Bike lanes on El Camino Real through Menlo Park?

August 31, 2015

Buffered bike lanes are being considered for El Camino Real, Menlo Park.

Buffered bike lanes are being considered for El Camino Real, Menlo Park.

There’s a move afoot to add an experimental bicycle lane and accompanying buffer on El Camino Real through Menlo Park. The experiment may last for six months or a year, yet to be determined.

I don’t have a problem with the experiment, but don’t expect miracles. I used to live in Menlo Park, but I hardly ever rode my bike on El Camino Real through Menlo Park, or to downtown for that matter.

It was traffic-crazy. I had to contend with a million driveways and lots of cars going in and out. The intersections are jammed most of the day. It’s bike unfriendly to say the least.

Adding the bike lane does not remove the hazards of cars entering and exiting driveways or turning right or left, which I consider a greater threat than being hit from behind on a straight section of El Camino Real.

I see the biggest advantage coming from slowing car traffic, and more drivers avoiding that stretch of El Camino Real.

Whatever the outcome, we need to be thinking long-term about accommodating bikes on roads. I’m talking about 50-100 years. It’s going to take that long for things to change.

The big improvement will come once autonomous cars arrive and it’s safe to ride a bike. That combined with electric bikes that make riding easy will change how we get around forever.

Let’s not forget that the Bay Area is unique compared to the rest of the U.S. where they have something called weather. There is no weather to speak of here (heat, cold, snow rain), so local cities have a much more compelling reason for accommodating bikes on roads to ease traffic congestion.

Electric bicycles, mushrooms and solid tires

December 7, 2014

Skyline Boulevard looking at Old La Honda Road.

Saturday I tried out an electric bicycle at Bicycle Outfitter (BO) and had a chance to discuss its prospects with the staff.

At BO, as with most bike shops, electric bikes are greeted with mixed feelings. I can relate to that. When a rider goes blasting by on an electric bike, I’m none to happy, then wish I had one.

However, electric bikes are already well established in China and are gaining a following in Europe. They have their place for commuting, the market they’re going after.

The bike I rode Saturday is a commuter with a top speed of 20 mph, if you’re just running on battery power and not pedaling. It looks like the typical commuter bike with a long wheel base, solid frame, motor in the rear hub. The battery is removable and sits over the rear wheel.

While the bike had heavy, durable tires, I wouldn’t ever want to have a rear flat. Were I to own one, I’d mount the new Tannus solid tire out of Korea. Solid tires have been around for decades, but this latest version looks promising. (One user’s experience.)

It’s lightweight and has decent rolling resistance, not as good as a pneumatic tire of course, but close enough. From what I’ve read, the only drawback is that it’s a bear to mount on a standard rim. It’s rated for 6,000 miles. That means it will probably last at least several years for a commuter.

So what about the performance rider who still wants go to electric? I’ve found two wheels that hold promise — the FlyKly and the Copenhagen. They’re similar in design and both have something else in common that has many buyers frustrated. The wheels were supposed to be available months ago.

As with any new product, production delays can be expected, and because there’s electronics involved, it gets more complicated. The product has to work flawlessly. If it doesn’t, someone could be injured and lawsuits would quickly shut down the companies.

While I won’t go into the details, I would be torn between which one to buy. The FlyKly appeals to the minimalist in me. It’s unobtrusive and weighs only 6.6 pounds. The drawback is that it only works with a single speed.

The Copenhagen is painted a garish red, weighs 13 pounds, but works with any standard road bike. Just swap wheels and you’re all set. Both wheels are wireless and require an app running on a smartphone, iOS or Android.

Once they come out, I’ll be interested to read the reviews. At about $700, they’re relatively affordable. For someone who commutes longer distances, they could pay for themselves in short order.

Meanwhile, with the recent rains my chanterelle friends have finally returned after a two-year absence. They’ll join me and spaghetti for dinner in the coming days.

Chanterelles are back after a long absence. They like rain.

Here’s the recommended “Hedding” to cross Santa Clara Valley

June 20, 2014

Hedding Street offers the best cross-valley route through downtown San Jose.

Hedding Street offers the best cross-valley route through downtown San Jose.

If you’re crossing Santa Clara Valley, it might seem daunting. It’s about 16 miles of suburban sprawl with a stoplight every quarter-mile. Lovely.

In my years of doing the crossing, typically on rides up Mt. Hamilton, I’ve found the best route: Homestead Road, Tantau Avenue, Pruneridge Avenue, Hedding Street, Mabury Road, White Road, McKee Road.

That’s a straight shot with the least amount of traffic, avoiding freeway intersections with exit ramps. It’s the route to take if you’re heading up Mt. Hamilton or visiting Alum Rock Park.

If you read the Roadshow in the Mercury News, you know that some commuters have complained about the Hedding Street restriping in the downtown area. It went from four lanes to two, with a wider, green-stripe bike lane.

I rode there this morning about 7:30 a.m. and again at 12:15 p.m. I didn’t see any traffic. The most cars at a light was nine at First Street and they easily cleared the intersection at the light change.

Granted, I wasn’t there at 5 p.m. on a Tuesday, which is probably the worst time, but I can’t imagine it’s the horror show motorists claim.

If they think traffic in San Jose is bad, they need to get out more. Try Hong Kong or Manila or even Milan at rush hour. San Jose is a ghost town by comparison.

Wall of Shame

January 15, 2014

Sometimes we do silly things we later regret and we’re none the worse off for it. However, other times we do dumb things and pay a price.

I’m recording what I see on my daily commute. I’ll call out cars, bikes and peds.

Mar. 6, 7:15 a.m., San Tomas Expwy northbound before El Camino Real. Cyclist texting while riding no-hands. It was no fun passing him.

Feb. 14, 7:05 a.m., Forbes Ave. and San Tomas Expwy. Cyclist runs red light westbound on Forbes. He takes his time about it.

Feb. 12, 4:45 p.m., Monroe Street near San Tomas Expwy. Bike crossing. Car runs red light. I’ve seen this 4 times now. It’s a confusing place for cars.

Feb. 10, 7:05 a.m. Forbes Ave. and San Tomas Expwy. Cyclist riding south on San Tomas runs red light.

Jan. 30, 7:20 a.m. Walsh Ave. and Bowers Ave., W on Walsh. Cyclist runs red light. Same rider as Jan. 14-15, so I won’t mention again. Free-radical cycling make sense for one person, but falls apart when every commuter tries it. Pavement sensor detects bikes fine here.

Jan. 17, 4:45 p.m., San Tomas Expwy and El Camino Real. The San Tomas Expwy multi-use path between Cabrillo Ave. and El Camino Real is open. I rode it and enjoyed the experience. Southbound on the path, a polite driver yielded so I could take the right-turn crosswalk at El Camino. I would have done the same as a driver. If you don’t have eye contact with the driver, assume he won’t stop.

Jan 16, 7:25 a.m. Benton St. and San Tomas Expwy. Five boys on BMX bikes race across San Tomas westbound on Benton, several taking the pedestrian crosswalk against traffic, no helmets. The ones going with traffic sprint across Benton in front of approaching cars, joining the wrong-way riders continuing to school. I don’t mind the lack of helmets, but who taught them to ride against traffic and dodge in front of cars? I see them daily, so this will be my last mention.

Riding against traffic can be fatal.

Jan. 30, 7:20 a.m., Walsh Ave. and Bowers Ave., W on Walsh. Cyclist runs red light. Same rider as Jan. 14, 15. I won’t mention this one anymore. The pavement sensor detects bikes fine at this intersection. Free-radical cycling can make sense to an individual, but falls apart when every commuter adopts the same philosophy.

Jan. 16, 7:15 a.m. Forbes Ave. and San Tomas Expwy. A youth about age 10 rides his BMX bike west on Forbes across San Tomas running a red light. No lights, no helmet, dark clothes in the pre-dawn light. Did his parents teach that behavior?

Jan. 15, 7:30 a.m. Walsh Ave. and Bowers Ave., W on Walsh. Cyclist runs red light. Same cyclist as Jan. 14. He REALLY knows what he’s doing.

Jan. 14, 7:30 a.m., Walsh Ave. and Bowers Ave., W on Walsh. Cyclist runs red light. Aren’t bikes supposed to stop at red lights? This cyclist had other ideas as he slowly worked his way across the busy intersection. He looks like a highly skilled rider.

Jan. 14, 7:40 a.m., Kifer Rd. and Semiconductor Drive. Riding while on phone. The cyclist gets a call, pulls onto the side walk while riding, wobbles around and takes a call as he rides back into the street. Unbelievable.

Pedestrian lights are for pedestrians

Being predictable on a bike could save your life and being unpredictable could cost you your life.

Recently I saw one of the most bizarre cycling behaviors, one that could have easily caused an accident. Fortunately it didn’t, but the cyclist should know why his action was so dangerous. Unfortunately he’ll probably never read this.

I was driving south on Saratoga Avenue in the right-turn only lane to enter the Interstate 280 on-ramp around 6 p.m. A cyclist was ahead with lights on and wearing a helmet. He looked like he knew what he was doing. I stayed behind him because the intersection was only 50 yards ahead. What really ticks me off is when a right-turning motorist pulls in front then stops so you can pass. I make a point of going left when I can. Treat bikes as you would a car and everything will be fine.

The light was green. The rider then slowed and pulled off the road. He punched the pedestrian light to make the orange hand turn white for go! At this point I slowed, not knowing his intentions. It’s a good thing I wasn’t rear-ended.

All he had to do was keep straight and everything would have been fine. Even if the light were red, he shouldn’t have pulled off the road to punch the light. In some situations where the button is within arm’s reach, that’s OK, but not when you have to pull off the road.

If you’re going to push a pedestrian light like that, you’d best be off your bike walking.

Ride like a motorist and you’ll be treated like one (usually).

Predictable riding, and traffic planning, essential for safety

December 29, 2013

Confusion on Calabazas. Do we want bike lanes crossing traffic lanes?

Confusion on Calabazas. Do we want bike lanes crossing traffic lanes?

A co-worker complained about the bike lanes on Calabazas Boulevard, Santa Clara, so I checked it out, and he was right.

I’m not a traffic engineer, but one of the cardinal rules of road design has been violated here: bikes keep right. Why oh why were the bike lanes put on the far left? Confusion reigns.

As I was stopped at Calabazas northbound at the El Camino Real light a motorist pulled up next to me in his convertible and engaged me in a conversation. He said I was the first rider he had seen using the bike lane on the left. I told him this was an unusual setup, to be sure.

I proceeded on Calabazas, a tree-lined one-way road divided by Calabazas Creek. It felt weird riding on the far left. At intersections I felt uncomfortable, wondering if cars on my left crossing Calabazas would be looking for bikes in this location. On top of this, there’s a weird sign with a car and a red-stripe through it. No cars in this lane. What’s that all about?

The El Camino Real intersections are equally confusing. The green paint shows up in two locations. Am I supposed to be in the far left lane when turning left or the one farther right? And where do cars go?

I made the mistake of being in the left side going south crossing El Camino. The small sign said “bikes left on green only.” I was kind of taking a left to get across to Calabazas, but when the car turning left from Calabazas nearly ran me over, I realized my mistake. Could have been fatal. This is an unusual left turn to begin with. Now it’s downright confusing.

Another oddity is the bike lane crossing Calabazas at an angle as it approaches Pomeroy. What if I’m turning left? It’s all wrong.

The old road alignment (two lanes one way both directions) was fine. The bike lanes were on the right. Now technically they weren’t perfect bike lanes because cars parked on the street take up too much of the lane (open door a hazard), but they could easily have taken out a lane and had parking as well as a bike lane.

Unfortunately the vehicle code (21208) says bikes must use the bike lane, with a few exceptions.

No doubt this street has a fair amount of traffic on weekdays with Wilcox High School nearby.

The city of Santa Clara, which has a bike committee, needs to revisit this road design and get it right: bikes keep right.

Finders Keepers, Losers Weepers

February 27, 2013

What do you do when you find a wallet or something of value? It's something to think about.

What do you do when you find a wallet or something of value? Think about it.

Cyclists, more than motorists, find things while riding. The questions is, what do you do when you find something of value? Keep it?

We all know the old saying, “Finders keepers, losers weepers.” I think most of us would rather do the right thing though. But just a minute here. I have a story to tell.

Jobst Brandt and Brian Cox were out for a Sunday ride on Skyline Boulevard when Jobst spied a wallet. He stopped, found the owner’s address, and realized it was just a short distance away on Las Cumbres Road.

I could tell you a story about some rides down Las Cumbres and beyond, but that’s one of those Once Upon a Ride events.

The riders pedaled over to the owner’s fancy house and knocked on the door. The occupant answered and Jobst explained how he found the wallet on Skyline.

Immediately the ungrateful owner started accusing Jobst and Brian of stealing money from the wallet. It was a ugly scene, one that caused Jobst to re-think what he would do the next time he found something of value.

From what I can find online, many people put wallets into mail boxes and let the postal service handle it. Or they give it to the police.

You can never free yourself from the potential accusation that you’ve stolen something, so maybe the postal drop is the best way to go, although it may be illegal, technically speaking, to put anything in a mailbox other than postmarked materials.

I’ve never found a wallet, but I found a cell phone on two occasions. I called the owners and both times they got their phones back. One owner worked just a mile from where I live.

We’ve all found money. I keep it but it’s small change. If you found money in a store and handed it over to the clerk, do you really think the owner would stop by looking for it? Or that the clerk would return it?

That’s a dilemma and one that I’ve never entirely resolved. Since the amount of money isn’t going to change your life, I think the best thing to do is donate it to charity and have a clear conscience.

Of course most of what I find on the road is the random tool and work gloves. Those go into my garage where they have a home and will be put to good use.

Trail Work Moves Ahead in South Bay

January 12, 2012

A dodgy section of trail from Zanker Road to Coyote Creek next to Hwy 237 is being paved in 2012. The sheep stay.

We have lots of good trail news in the South Bay to start the new year. First, the unpaved portion of the Guadalupe River Trail from I-880 at the San Jose airport extending to Alviso at Gold Avenue will be paved starting later this year.

The bad news is the trail will be closed for up to a year.

On another bright note, the notoriously bad section of trail (0.6 miles) paralleling the north side of Hwy 237 from Zanker Road to Coyote Creek will be paved in 2012. It’s actually not bad if you like a funky mix of old pavement and firm gravel. I will miss it in a way.

Now if only we could see the Coyote Creek Trail opened under Hwy 237. That one has always been a mystery to me.

Finally, it took millions of dollars to buy the land from Union Pacific, but we now have the land needed to build a trail linking Los Gatos Creek Trail with Guadalupe River Trail. It’s called the 3 Creeks Trail extension.

I didn’t see any projected opening dates, so I imagine it will be a few more years before we have a place to ride.
