Take a Look at Tampa’s First Protected Bike lane

Cycle Track -ANIMATION

Tampa is starting to make progress on safe bike infrastructure. Last weekend, Tampa Mayor Bob Buckhorn led a celebratory ride to mark the opening of the city’s first protected bike lane — a curb-protected two-way lane on Cass Street downtown.

The Cass Street project is one of the first protected bike lanes in Florida — a notoriously dangerous state for biking and walking. It’s about three-quarters of a mile long and the city intends to extend it in both directions, said Karen Kress of the Downtown Tampa Partnership.

The project also converted Cass Street from one-way to two-way car flow. While that introduces more potential motor vehicle turning movements across the bikeway, the project includes signals to reduce conflicts between drivers and cyclists.

Kress says locals are already responding. “It is blowing up,” she said. “There’s been so much pent up demand for safe cycling conditions. They’re coming out of the woodwork.”

Kress said her organization has been trying to help businesses find a place for all the bike parking employees are demanding.

The Cass Street bike lane — along with the green, buffered bike lanes on Platt, Cleveland, and Brorein streets that were added last year — emerged from a strategic planning process for the city’s downtown. Tampa was recognized by Smart Growth America recently for its strides toward walkability. The bike lane will help people biking to and from Tampa’s popular 2.5-mile Riverwalk, which was recently completed with help from an $11 million TIGER grant.

Eyes on the Street: London “Cycle Superhighway” Teems With Bike Traffic

In case you’re looking for a good visual to show how bike lanes can be extremely efficient transportation infrastructure, check out this short video from the UK-based advocacy group Sustrans. It shows rush hour on the Blackfriars Bridge “cycle superhighway” in London on a Tuesday morning.

London has been building out a network of “cycle superhighways” since 2008, but only in the last couple of years has the city started to emphasize physical protection from motor vehicle traffic in its bikeway designs. Here’s a look at what the Blackfriars Bridge bike lane looked like before a recent upgrade.

Bicycling in London has risen dramatically in recent years, with bikes now accounting for about a fifth as many trips per day as the Tube, according to Transport for London. In addition to better bikeways, policies like congestion pricing and slow speed zones have made the city’s streets safer and more appealing for people to get around by bike.

Cycling Booms in London, and the City’s Not Looking Back

Image: City of London

If current trends continue, there will be more people bike commuting in central London than car commuting by 2018. Image: City of London

Boris Johnson says that one of his goals as mayor of London was to make cycling “more popular and more normal.” As Johnson’s eight-year tenure winds down, it looks like the progress he made in his second term has accomplished that mission.

If current trends continue, bike commuters will outnumber car commuters in central London by 2018, according to a recent report from Johnson’s office [PDF]. Citywide, Transport for London estimates people already make 645,000 bike trips on an average day.

When Londoners head to the polls later this week to elect their next mayor, five candidates will be on the ballot, all of whom have signaled they will continue to expand the city’s bike network, reports the BBC’s Tom Edwards. Most of them have pledged to triple the amount of protected bike lanes in the city.

You can trace the London cycling boom to several factors, including the introduction of congestion charging under Johnson’s predecessor, Ken Livingstone, in 2003. But the big turning point came during Johnson’s second term, when bike advocates prompted him to get serious about installing protected bike lanes.

In his first term, Johnson championed the construction of “cycle superhighways” on some of the city’s busiest streets. But these routes, which offered little or nothing in the way of physical protection, didn’t live up to their billing. Cyclists were not satisfied with them and staged huge protests calling for safer bike infrastructure. The BBC’s Edwards recalls how cyclists booed Johnson when he was seeking reelection four years ago.

In recent years, Johnson has devoted more resources to protected bike lanes, upgrading the existing “cycle superhighways” and laying out a plan for more. He now says his “single biggest regret” was not doing so sooner.

When to Use Protected Intersections? Academic Study Will Offer Advice

If 2015 was the year protected intersections arrived in the United States, 2016 is the year the country’s bikeway pros are starting to really figure them out.

Inspired by Dutch streets, protected intersection designs use a few simple tricks to rearrange traffic at intersections so that people on bikes and in cars don’t have to constantly look over their shoulders for one another.

Last week, Portland State University announced a $250,000 project that will use simulations to put people on virtual streets and test their use of protected intersections. The goal: create data-driven standards to tell cities where protected intersections are needed.

“At what traffic volume?” asked Justin Carinci, a spokesman for PSU’s National Institute for Transportation and Communities. “At what speeds?”

Fast Changes to City Streets: A 9-Step Guide for Creative Bureaucrats

For most of the 20th century, cities answered transportation problems by adding more pavement.

More freeways. More lanes. More parking lots. More things that couldn’t be reversed or revised.

So it made sense, at the time, for the public process around civil engineering projects to focus, above all else, on not making mistakes. Generations of city workers embraced the value of “Do it once and do it right.”

But today’s transportation problems are different, and so are the projects that respond to them. Naturally enough, the process of planning and designing such projects has begun changing, too.

From the experimental lawn chairs scattered across New York’s redesigned Times Square on Memorial Day 2009 to the row of plastic posts on Denver’s Arapahoe Street after a bike lane retrofit last fall, city projects are tackling big problems with solutions that are small, cheap, fast and agile. But until now, no one has created a short, practical guide for cities that want to create a program to do things like these.

Today, we’re publishing that guide.

5 Strategies for Equitable Active Transportation Planning and Advocacy

Cross-posted from the Alliance for Biking and Walking

It started as a lively discussion on the Bike Equity Network — a listserv for mobility and equity advocates working within walk/bike advocacy and planning — related to a Washington Post article that examined the notion of bike lanes as symbols of gentrification. The online conversation that transpired was rich, frank, and underscored the need to bring the conversation to a broader audience in a more interactive format. So this month, the Alliance hosted a highly anticipated Distance Learning Webinar: “Active Transportation & Anti-Displacement.”

Co-facilitated by Dr. Mike Smart, Assistant Professor at Rutgers University, and featuring insight from several equity leaders, the webinar was a timely and candid conversation that provided Alliance members an opportunity to hear diverse perspectives from and ask questions of advocates working within academia and advocacy — and future planners in Dr. Smart’s class.

Special thanks to Dr. Mike Smart, as well as our presenters:

Listen to the full recording on SoundCloud here and read a summary of the main takeaways below. Also catch some of the conversation that happened on Twitter via hashtag #MobilityEquity. Enjoy!

Acknowledge that bicycle infrastructure is wrapped up in larger development processes spurring gentrification, which has in many cases been done on purpose.

American Sharrow Inventor: “I Was Always Under Pressure to Do Less”

Sharrows, what are they good for? A recent study suggests that one thing shared lane markings don’t do is improve safety for cyclists. The conclusion has sparked an online debate and some detailed defense of sharrows in the right conditions.

Seattle-based journalist Josh Cohen produces the Bicycle Story podcast, and in his new episode he digs into some of the history of sharrows in America. It’s illuminating stuff.

Cohen interviewed traffic engineer James Mackay, who pioneered the use of sharrows in America when he worked for the city of Denver’s bike program in the early 1990s. Mackay said the agency culture — one that resisted taking any risks to improve conditions for cycling — was a factor in the design:

I thought at that time of a sign to define that bicyclists were intended users of the road and define lane position and to confirm that jurisdictional agencies understood that bicyclists would be using the road there. We came up with a design that had the bicycle symbol, the bicyclists with the wheels, inside an arrow outline and it was quickly called the bike in the house with the man jumping barrels at home.

Part of it was the city of Denver’s reluctance to do much of anything for bicycles. So I figured, this would be a less expensive approach versus the conventional bike lane markings. A lot of the agencies don’t want to do anything involving change or spending money for bicycles. I was always under pressure to do less as the Denver bicycle planner.

He told Cohen that he even had to fight with city officials to implement sharrows properly:

Houston Unveils a Bold New Citywide Plan for Bicycling

The same team that helped overhaul Houston’s bus network is turning its attention to the city’s bike network.

This week, recently-elected Mayor Sylvester Turner unveiled the city’s first bike plan since 1993. The plan envisions a network of low-stress bikeways — a welcome improvement over Houston’s previous bike plan, from 1993, which mostly consisted of “share the road” signs and sharrows on wide, high-speed roads, according to Raj Mankad of OffCite, a blog of Rice University’s Design Alliance.

In 2012, Houston voters backed the creation of the Bayou Greenways network, 150 miles of linear trails along the city’s low-lying bayous. But without on-street connections, the greenways would be fragmented and people would have to bike on dangerous streets, writes Mankad.

The new plan calls for about 800 miles of on-street bike lanes — up from just 8 miles today — and about 400 additional miles of off-street paths. Though the plan doesn’t give a concrete timeline for completing the network, the goal is to achieve “gold-level” status from the League of American Bicyclists by 2026.

The estimated cost would be between $300 and $500 million. To put that in perspective, the pricetag is at most one-tenth of what the region is pouring into the “Grand Parkway,” a third ring road for the region.

How Cities Clear Snow From Protected Bike Lanes: A Starter Guide

pfb logo 100x22This post is by Tyler Golly of Stantec and Michael Andersen of The Green Lane Project, a PeopleForBikes program that helps U.S. cities build better bike lanes.

As protected bike lanes have spread from city to city across North America, a problem has followed: snow.

Most protected bike lanes are too narrow for standard street plows. So how are cities supposed to keep them clean?

Last year, the two of us decided to try and help more cities solve this problem by researching the best equipment to use for clearing snow from protected bike lanes. We wanted something like PeopleForBikes’ past post about the best sweepers for clearing protected bike lanes of leaves and debris.

But after talking to city staffers across North America and Europe, we realized that the challenges of winter are different than the challenges of fall. The reason is that winters themselves are so different from city to city.

The snow that piles into a protected bike lane in Chicago is very different in quantity, weight and thaw pattern than the snow in Calgary, which is very different than the snow in New York City.

Moreover, there’s just not as much variation among snow-plowing equipment. As one staffer we spoke to put it, the perfect plow rig for your bike lane is the biggest one that isn’t too big.

Study: Sharrows Don’t Make Streets Safer for Cycling

Sharrows are the dregs of bike infrastructure — the scraps cities hand out when they can’t muster the will to implement exclusive space for bicycling. They may help with wayfinding, but do sharrows improve the safety of cycling at all? New research presented at the Transportation Review Board Annual Meeting suggests they don’t.

A study by University of Colorado Denver researchers Nick Ferenchak and Wesley Marshall examined safety outcomes for areas in Chicago that received bike lanes, sharrows, and no bicycling street treatments at all. (The study was conducted before Chicago had much in the way of protected bike lanes, so it did not distinguish between types of bike lanes.) The results suggest that bike lanes encourage more people to bike and make biking safer, while sharrows don’t do much of either.

Ferenchak and Marshall’s study divided Chicago into three geographic categories using Census block groups: areas where bike lanes were added between 2008 and 2010, areas where sharrows were added, and areas where no bike treatments were added. They then looked at how bike commuting and cyclist injuries changed in these areas over time.

They found that bike commute rates more than doubled in areas with new bike lanes, compared to a 27 percent increase in areas with new sharrows and a 43 percent increase in areas where nothing changed.

Meanwhile, the rate of cyclist injuries per bike commuter improved the most where bike lanes were striped, decreasing 42 percent. Areas that got sharrows saw the same metric fall about 20 percent –worse than areas where streets didn’t change (36 percent), although the difference was not great enough to be statistically significant.
