How to Add Bike Lanes Without Messing Up Traffic Flow: An Animated Visualization

How to Add Bike Lanes Without Messing Up Traffic Flow: An Animated Visualization | green infographics |

As bike lanes get added to streets around the US one common concern keeps arising: how will this affect congestion? Narrowing roadways by including bike lanes seems like it would clearly increase car traffic, but data from New York City suggests that when done correctly, adding bike lanes can actually speed up traffic flow. Since 2007, the city has added over 30 miles of protected bike lanes.

The solution most commonly used? Road diets.

A road diet is commonly described as “removing travel lanes from a roadway and utilizing the space for other uses and travel modes.” There are many implementation strategies, but when done correctly they provide smoother traffic flow through neighborhoods and better safety for everyone using the road...

Smart Highways by Studio Roosegaarde

Smart Highways by Studio Roosegaarde | green infographics |

Glow-in-the-dark roads and responsive street lamps were among the concepts to make highways safer while saving money and energy at the Design Indaba conference in Cape Town earlier this month.

The Smart Highways project by Studio Roosegaarde proposes five energy-efficient concepts that will be tested on a stretch of highway in the Brabant province of the Netherlands from the middle of this year.

The first of the concepts is a glow-in-the-dark road that uses photo-luminescent paint to mark out traffic lanes. The paint absorbs energy from sunlight during the day the lights the road at night for up to 10 hours. Temperature-responsive road paint would show images of snowflakes when the temperature drops below zero, warning drivers to take care on icy roads.

There are two ideas for roadside lighting: interactive street lamps that come on as vehicles approach then dim as they pass by, thereby saving energy when there is no traffic, and "wind lights" that use energy generated by pinwheels as drafts of air from passing vehicles cause them to spin round. Additionally, an induction priority lane would incorporate induction coils under the tarmac to recharge electric cars as they drive...

First we learned to sequence traffic lights.  Now we can capture energy for better road marking.  Next we will have computer guided car tracks that let us travel more efficiently as a group better utilizing existing highways.  Add in more fuel efficient or electric cars and we have a pretty good outlook for cleaner cities and less dependency on non-renewable resources.

If there is one area that needs focus and improvement it is highways. Agreed!

When people feel safer they are more likely to ride a bike, and they feel safer in bike lanes.

The idea of "vehicular cycling", where cyclists share the road with cars and act like cars, is looking sillier with every new study. A few weeks ago a study showed that a shocking 40% of cycling deaths happened when a cyclist was rear ended, usually on arterial roads. Now a new study, Lessons from the Green Lanes, provides clear evidence that separated bike lanes work really well, not only at saving lives, but in attracting more cyclists, making cyclists feel safer, and increasing economic activity.
