Streetfilms has been documenting the open streets movement for over seven years, beginning with our landmark film in 2007 on Bogota's Ciclovia, currently the most viewed Streetfilm of all time.

There's nothing more dramatic than looking back five or ten years at Streetfilms footage to see how much the streets of New York City have changed. In this wonderful montage, check out the incredible changes at Times Square, Herald Square, the Brooklyn waterfront, and many other places that outgoing NYC DOT Commissioner Janette Sadik-Khan and her staff have intrepidly transformed.

Without a doubt, 2013 has been a banner year for bike-share in the United States. Major systems were implemented in New York City and Chicago, and many others debuted or expanded in other cities. In fact, Citi Bike users have biked over 10 million miles and the system is closing in on 100,000 annual members!

Portland's South Waterfront is developing into one of the best new walkable urban neighborhoods in America. From one spot, you can grab the Portland Streetcar, ride the Portland Aerial Tram to Oregon Health and Science University, walk across abrand new pedestrian bridge, bike on a protected bikeway, or park your bike at the largest daily valet bike parking facility in the country.

Here we present our final -- and most informative -- Streetfilm from Amsterdam. It provides a nice cross-section of commentary on life in the City of Bikes. If you'd like to skip directly to a certain section, use this table of contents:

If you haven't seen the latest Streetfilm, Groningen: The World's Cycling City, you should check it out. Like, now! It has broken every single Streetfilms viewing record -- nearly 40,000 plays in just the first week.

It's no secret that just about anywhere you go in the Netherlands is an incredible place to bicycle. And in Groningen, a northern city with a population of 190,000 and a bike mode share of 50 percent, the cycling is as comfortable as in any city on Earth. The sheer number of people riding at any one time will astound you, as will the absence of automobiles in the city center, where cars seem extinct. It is remarkable just how quiet the city is. People go about their business running errands by bike, going to work by bike, and even holding hands by bike.

The future looks bright for Pittsburgh for 2014. As they prepare to host the Pro Walk Pro Bike Pro Place conference next September, last week Project for Public Spaces held a one-day summit in advance of next year's big event.

On a Bixi bike excursion to get some ice cream in Montreal, my wife and I stumbled upon the intersection of Fairmount Avenue and Rue Clark, recently upgraded with colorful new street furniture, traffic calming treatments, and a two-way protected bike lane. The space is teeming with street life. When you arrive at this lovely place your first instinct is to stop, sit down, and enjoy.

While spending a week in Montreal, my wife and I stayed right along the Rue Sainte Catherine, which we discovered is closed to motor vehicles from May 15 through September 6 in two main sections. The first, a mile-long stretch that's been car-free in the summer since 2008, has a lot of restaurants and is filled with pedestrians all night long. The second, a more recent addition, is a smaller section to the west which features plenty of programming and music near the Place des Arts.
